ting it into operation. It identifies the minimal requirements for getting the system up and running. WARNING: This QuickStart Guide assumes that installation procedures will be performed by qualified professionals following all safety and other requirements and acting in accordance with standard prac-

tices and procedures. Failure to meet safety requirements and/or non-standard practices and procedures could result in personal injury and/or damage to equipment. All of the instructions presented in this chapter are discussed in more detail in subse-

quent chapters of this manual and in the PacketWave 100 Series Subscriber Equip-

ment Installation and Operation manual. 070-20000340-01 Rev A 11 CHAP TER 1. Q UICKSTAR T GUIDE PLANNING, SITE PREPARATION, AND CONFIGURATION Before you begin installing the PacketWave equipment, make sure you properly plan the overall system and individual sites. Step 1. Determine and Prepare Locations A. Make sure that the base station is located such that it can communicate with sub-

scribers. Cell sector width may be 60 or 90, depending on the antenna chosen. Distance between base station and subscriber site may be up to 5 miles for line-

of-sight or near-line-of sight communications, or up to 1 mile for non-line-of-

site communications. B. Make sure that the base station site includes a proper mounting structure for the radios and antennas, and an indoor location for the Base Station Unit. Maximum cable length is 165 feet (50 m) without dc insertion from an external source. C. Make sure all subscriber sites have an appropriate radio/antenna support or mounting location. Maximum cable length between subscriber Indoor Units

(bridge/routers) and Outdoor Units (radio/antennas) is 165 feet (50 m) without dc insertion from an external source. Step 2. Define IP Networking A. Each cell sector is served by a separate wireless subsystem (WSS) in the Base Station Unit. The WSS wireless interface will be the gateway for all subscribers it serves, which typically define a single subnet. Determine the WSS interface

(gateway) address based on the available IP address space and desired subnetting. NOTE: The PacketWave System supports VLSM. B. The Base Station Unit requires a DHCP server from which it and subscribers receives IP addresses and other basic configuration information, and a TFTP server from which they download configuration files. i. The DHCP server, or a DHCP relay agent pointing to it, must be on the same subnet as the BSUs backhaul interface for the BSU to locate the DHCP server. ii. The address of the TFTP server is provided by the DHCP server, so may be any reachable IP address. C. If SNTP (time), SMTP (mail), SNMP, and/or Syslog servers are to be imple-

mented, their IP addresses will be required during BSU configuration. 070-20000340-01 Rev A 12 Step 3. Create BSU Configuration File(s) CHA PTER 1. Q UICKSTAR T GUIDE A. Load and run the WaveCenter Configuration Manager program (provided on CD). NOTE: The program can be run on the TFTP server or another computer from which the files can be downloaded to the TFTP server. The Configuration Manager runs on Windows 98, NT, or 2000 Professional; Linux; or Sun Solaris. B. From the opening screen, click on the BSU icon to open the BSU Configuration Manager. For WSS 1:

i. Go to the WSS Multiple Subnets menu and specify the WSS IP Address and WSS Subnet Mask (mandatory). NOTE: If multiple subnets are to be implemented for the WSS, click on the new instance icon and repeat the step above until all subnets are defined. ii. Go to the WSS Channel menu and specify the Channel Center Frequency (mandatory). iii. If desired, configure any optional WSS parameters as described in Chapter 6 of this manual. iv. Save the configuration by clicking the Generate WSS Config button and following the prompts. v. For an additional WSS, click on the new instance icon on the WSS Mul-

tiple Subnets menu, which will increment the WSS number (Host ID). Then return to step i above. When all WSS are configured, proceed to the step C. C. Go to the MAIN General menu and specify the Base Station Units MAC Address. D. If desired, configure any optional BSU parameters (MAIN, SNMP, and ALERTS menus) as described in Chapter 6 of this manual. E. When all configuration has been completed, generate the BSU configuration file by clicking on the Generate BSU Config button and following the prompts. Save the config file with a name uniquely linking it to the BSU; Aperto recommends the default format bsc_<MACaddress>.cfg. F. Close the BSU Configuration Manager. If there are additional BSUs to configure, return to step B. 070-20000340-01 Rev A 13 Step 4. Create Subscriber Configuration Files CHAP TER 1. Q UICKSTAR T GUIDE A. From the WaveCenter Configuration Managers opening screen, click on the subscriber Indoor Unit icon to open the subscriber (CPE) Configuration Manager option. i. Go to the System menu and specify the MAC address, CPE Mode and CPE Model (mandatory). ii. iii. If the CPE Mode is NAT, you may go to the NAT menu and configure as desired. However, the defaults will work for basic operation. If the CPE Mode is Router, you may go to the Router menu and configure as desired. However, the defaults will work for basic operation. (Standard routing is not supported in R1P1.) B. If desired, configure any other optional subscriber parameters as described in Chapter 6 of this manual. C. When all configuration has been completed, generate the subscriber configuration file by clicking on the Generate Configuration File button and following the prompts. Save the config file with a name uniquely linking it to the subscriber Indoor Unit; Aperto recommends the default format cpe_<MACaddress>.cfg. D. Close the CPE Configuration Manager. If there are additional subscribers to configure, return to step A. Step 5. Configure the TFTP and DHCP Servers A. Download all BSU and subscriber configuration files to the default TFTP direc-

tory on the TFTP server. B. Configure the DHCP server for the following:

IP address and subnet mask for TFTP server, and for other servers as desired. Range(s) of assignable addresses, with subnet masks and gateway addresses. BSU MAC address and the name of the corresponding configuration file to be found on the TFTP server. For each subscriber Indoor Unit, its MAC address and the name of the corre-

sponding configuration file to be found on the TFTP server. NOTE: If desired, different DHCP servers can be defined for the BSU and for sub-

scribers. C. Make sure that the DHCP and TFTP servers are running. 070-20000340-01 Rev A 14 CHA PTER 1. Q UICKSTAR T GUIDE INSTALLING AND STARTING BASE STATION EQUIPMENT The steps in this section outline the physical installation of the base station equipment.

(See Chapters 4 and 5 of this manual for details.) Step 6. Install Base Station Radios and Antennas A. Mount the PacketWave radios and antennas on the antenna mast or other support structure using the mounting brackets supplied, or other brackets as required by the support structure. Observe minimum distances between antennas and maxi-

mum radio-to-antenna distances. B. Connect the radios RF jumper cables to the appropriate connectors on the antenna. C. Install radio signal and control cables between each radio and the Base Station Unit location. Label the cable ends to prevent misconnections.

- Radio signal cable (RG6, 75 ohm, quad shield coaxial, male F connectors)

- Radio control cable (shielded outdoor Cat 5, male RJ45 connectors) The Radio Control interface on the Base Station has the same physical appearance as the 10/100Base-T interface. Make sure you connect to the right one. Step 7. Install the Base Station Unit A. Mount the Base Station Unit in an equipment rack, allowing for adequate air flow around and through the unit. B. Connect the radio signal and control cables from the outdoor radios to the proper ports on the BSU front panel. NOTE: No other connections to the front panel are necessary for a site with a single BSU. See Chapter 4 for discussions of optional connections and/or multiple BSUs. C. Connect 120 V ac or -48 V dc to the rear panel connector, as appropriate. Connecting power will cause the Base Station Unit to boot up, locate the DHCP server and obtain basic configuration information from it, then download its full configuration file from the TFTP server. NOTE: If power is connected before the DHCP server is configured and the BSUs configuration file is available in the TFTP server, or if either of the servers is unreachable, the BSU will power up in standby mode. It will need to be rebooted when the servers are fully configured and reachable. 070-20000340-01 Rev A 15 CHAP TER 1. Q UICKSTAR T GUIDE After the first successful loading of the BSU configuration file from the TFTP server, the configuration will be stored in nonvolatile memory on the BSU. Thus, if the BSU is rebooted when the TFTP server is unreachable, the BSU will operate with its exist-

ing configuration rather than going into standby mode. INSTALLING AND STARTING SUBSCRIBER EQUIPMENT The steps in this section outline the physical installation and initialization of equip-

ment at the subscriber site. See the PacketWave 100 Series Subscriber Equipment Installation and Operation manual for details. Step 8. Prepare for Installation A. Before visiting the subscribers site:

i. Make sure that the necessary system configuration has taken place, as described in the PacketWave 1000 Base Station Unit Installation, Configu-

ration, and Operation manual. ii. Make sure that the DHCP and TFTP servers are running. iii. Verify that the subscriber configuration file has been created and saved on the TFTP server. iv. Verify that the DHCP server has been configured with the subscribers IP and MAC addresses and its configuration file name. B. At the subscribers site:

i. ii. Identify the location for the Indoor Unit (bridge/router). Identify an appropriate location for mounting the Outdoor Unit, where it can be pointed at the base station with the least possible obstruction iii. Determine the cable path between the Indoor Unit and the Outdoor Unit. Maximum cable length is 165 feet (50 m). Step 9. Install the Outdoor Unit (Radio/Antenna) A. If a mounting pole or other support is to be employed, install it in the chosen loca-

tion, following standard procedures and local building codes. The Outdoor Units mounting bracket accommodates diameters of 1.5 inches, 2 inches, or 5 cm. B. Mount the Outdoor Unit to the support or to the building. 070-20000340-01 Rev A 16 Step 10. Install the Indoor Unit (Bridge/Router) CHA PTER 1. Q UICKSTAR T GUIDE A. To start, in most cases, the Indoor Unit should be temporarily placed close to the Outdoor Unit to facilitate antenna alignment process. When the installation of the-

Outdoor Unit is complete, move the Indoor Unit to its permanent location. Make sure the Indoor Unit is located near an electrical power outlet or power extension cord will be needed. WARNING: For proper cooling, the Indoor Unit must be installed in the upright position, with adequate air flow around and through it. B. Assuming that the Indoor Unit is located at a temporary location, run spare radio signal and control cables between the Outdoor and Indoor Units.

- Radio signal cable (quad shield coaxial, male F connectors) Radio RF connectors on the Outdoor and Indoor Units.

- Radio control cable (shielded outdoor Cat 5, male RJ45 connectors) Radio Control connectors on the Outdoor and Indoor Units. The Radio Control interface on the Indoor Unit has the same physical appearance as the 10/100Base-T interface. Make sure you connect to the right one. Step 11. Initialize the Subscriber Equipment A. Connect the power module between the Indoor Unit and a wall outlet. B. Perform antenna alignment procedure (see the PacketWave 100 Subscriber Equip-

ment manual, or the addendum on this subject). C. If the Indoor Unit is located at a temporary location, move the Indoor Unit to its permanent location. WARNING: For proper cooling, the Indoor Unit must be installed in the upright position, with adequate air flow around and through it. D. Use the permanent radio signal and control cables to connect the Outdoor Unit to the Indoor Unit.

- Radio signal cable (RG6, 75 ohm, quad shield coaxial, male F connectors) between Radio RF connectors on the Outdoor and Indoor Units.

- Radio control cable (shielded outdoor Cat 5, male RJ45 connectors) between Radio Control connectors on the Outdoor and Indoor Units. 070-20000340-01 Rev A 17 CHAP TER 1. Q UICKSTAR T GUIDE Step 12. Configure Subscriber Hosts A. Connect the subscribers computer(s) to the 10/100Base-T interface on the Indoor Unit, using a straight Ethernet cable for connection to a hub or a crossover Ether-

net cable for connection directly to a computer. B. Typically, the only other thing necessary to connect a subscriber host computer to the PacketWave network and beyond is to configure the hosts TCP/IP to obtain its IP address using DHCP. Instructions should be available using the computers online help 070-20000340-01 Rev A 18 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW 070-20000340-01 Rev A 22 Cell Size, Capacity, and Scalability CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Apertos advanced wireless technologies support a wide range of cell requirements, and make PacketWave an exceptionally scalable solution. PacketWave cell specifica-

tions include:

Cell radius can easily reach 5 miles (8 km) with line-of-site transmission paths, or about 1 mile (1.6 km) with obstructed paths. Each Base Station Unit can support up to 250 subscribers per sector, with a maximum of six sectors. A cell can employ multiple Base Station Units. Thus, a single cell can serve thousands of subscribers. The bandwidth capacity for a Base Station Unit is 120 Mbps, based on a max-

imum raw bit rate of 20 Mbps per sector. Subscriber data rates can be individually configured from 384 kbps to 10 Mbps;

with bursts to 20 Mbps. The ratio of downstream to upstream traffic can be adjusted between 90%

downstream/10% upstream and 90% upstream/10% downstream. The PacketWave System ensures that a wireless network can grow to thousands of subscribers in urban or suburban areas through high frequency reuse and dense multicell deployment. Combining high frequency reuse with advanced interference management and mitigation techniques, the PacketWave System conserves valuable spectrum by covering extensive geographical areas with a minimum number of channels. As the number of subscribers and the bandwidth needs in a cell increase, new sectors can be added, and multiple PacketWave 1000 Base Station Units can be stacked to provide additional bandwidth using multiple channels per sector. To extend service offerings geographically, a service provider simply deploys additional cells. Multiple Frequency Bands The PacketWave System can be deployed in the standard frequency bands used vari-

ously throughout the world for licensed or unlicensed wireless broadband networking. The PacketWave 1000 Base Station Unit can support PacketWave radios and antennas operating in 2.5 GHz MMDS, 3.5 GHz FWA, 5.3 GHz, and 5.8 GHz U-NII bands with no physical or software reconfiguration. Similarly, any PacketWave 100 Series Subscriber Indoor Unit (bridge/router) can support the same range of frequency bands. 070-20000340-01 Rev A 23 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW IP-Based System The PacketWave System leads the industry in the implementation of advanced IP fea-

tures and services. Packet filtering, DHCP snooping, and ARP snooping conserve bandwidth for subscriber traffic. Support for IP RIP routing, multiple subnets per sec-

tor, Variable-Length Subnet Mask (VLSM), and Classless Internet Domain Routing

(CIDR) ensure complete control of IP address management and network configura-

tion. PacketWave Series 100 Subscriber Indoor Units support bridging, IP routing, and NAT for flexible deployment. Because the PacketWave System is based on IP end-to-end and IP networking skills and resources are relatively common, the PacketWave solution helps service providers to control costs, expand service options, expedite configuration, simplify connection to the Internet, and minimize time to market. The ubiquity of IP also allows native support for value-added Internet applications such as VPN, web hosting, and video-

conferencing. Range of Backhaul Options The PacketWave 1000 Base Station Unit offers both flexible and cost-effective solu-

tions to connect to backhaul networks. In its basic configuration, PacketWave 1000 supports 10/100 Mbps Ethernet. This enables the PacketWave 1000 to connect directly to an Ethernet-based MAN or, through an external router, to a variety of broadband network technologies. Through future plug-in modules, other backhaul options, such as ATM, will be directly supported. In addition, external optical or high-

capacity wireless backhaul such as millimeter wave technology can be implemented. Where other backhaul options are not available, one of the Base Station Units wire-

less channels can provide a link to a backhaul network. Whatever the backhaul option, quality of service (QoS) is maintained throughout the network using either IP Differentiated Services (DiffServ), ATM Service Categories, or MPLS. Subscriber and Network Management The PacketWave System simplifies subscriber and network management by using GUI-based tools, standard protocols, and industry-standard platforms. One of these tools is the highly-scalable, Java-based WaveCenter Configuration Manager, which automates the subscriber provisioning process. In addition to the WaveCenter Configuration Manager, the PacketWave System also includes Web-based and SNMP-compliant network management software for configuration, fault, perfor-

mance, and security management. 070-20000340-01 Rev A 24 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Technological Innovations At the heart of PacketWave's revolutionary performance are three innovative Aperto Networks technologies: RapidBurst, OptimaLink, and ServiceQ. RapidBurst RapidBurst technology enables the PacketWave System to achieve exceptionally low latency and high spectral efficiency. Advanced Time Division Multiple Access

(TDMA) burst mode ensures maximum flexibility and efficiency in both upstream and downstream transmissions. Adaptive Time Division Duplexing (TDD) allows operation in a single channel anywhere in the spectrum. Dynamic bandwidth alloca-

tion assigns time slots and packet sizes depending on specific traffic flows. With RapidBurst , the PacketWave System provides up to 120 Mbps of bandwidth per cell with one base station. OptimaLink OptimaLink technology individually optimizes the reliability and throughput of each Subscriber wireless channel by dynamically adjusting up to ten PHY- and MAC-layer parameters. The result is increased coverage, extending broadband services to subscribers who would otherwise be unreachable due to obstructed-line-of-sight or non-line-of-sight conditions. ServiceQ ServiceQ technology provides different quality of service (QoS) levels to subscribers on a flow-by-flow basis enabling differentiated service offerings and effective man-

agement of service level agreements (SLAs). Various service levels can be defined in three service classesConstant Bit Rate (CBR), Committed Information Rate (CIR), and Best Effort (BE). The percentage of bandwidth allocated to each service class is adjustable depending on the mix of service offerings. ServiceQ supports high-quality video and telephony applications. Each service flow can be associated with a specific host or application and can be assigned to any service class, so application-specific services with QoS can be offered. 070-20000340-01 Rev A 25 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW BASE STATION (CELL SITE) EQUIPMENT PacketWave base station equipment includes the PacketWave 1000 Base Station Unit and associated radios and antennas. Base Station Unit The PacketWave 1000 Base Station Unit, shown in Figure2-2 , is a single rack-

mounting controller unit which supports any of the PacketWave System radio and backhaul options. There are two models, one with an ac power supply and one with a dc power supply. Figure2-2 PacketWave 1000 Base Station Unit In the basic configuration pictured, the PacketWave 1000 includes:

Four built-in wireless interfaces for connection to radios and their associated antennas. A 10/100Base-TX Ethernet backhaul interface. Synchronization interfaces for multiple colocated Base Station Units. A local RS-232 craft management port. An external clock interface. A dry-contact relay which can be configured to operate a local alarm device or to control redundant equipment such as a backup radio and antenna. 070-20000340-01 Rev A 26 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Two slots for plug-in modules.

- One slot will support a dual wireless interface unit, allowing a total of six wireless interfaces in the Base Station Unit.

- The second slot will support an alternative backhaul interface. Modules sup-

porting additional backhaul options, including ATM, are under development. Multiple Base Station Units Subscriber density and bandwidth requirements may combine to exceed the capacity of a single Base Station Unit. Part of the scalability built into the PacketWave System is the ability to colocate and link multiple Base Station Units at a cell site. Through the use of different center frequencies within the systems frequency band, sectors can be overlaid within the cell to serve additional subscribers, providing a virtually unlim-

ited growth path. To coordinate the Time Division Multiple Access (TDMA) and Time Division Duplexing (TDD) on which the PacketWave wireless communication is based, it is necessary for all Base Station Units in a cell to be synchronized in terms of signal framing and time slot identification. Sync ports on the Base Station Unit allow all units to share the same framing, with inputs for a main and alternate BSU to provide the framing signal. Base Station Radios and Antennas PacketWave base station radios and antennas deliver the benefits of a single-source, thoroughly-tested base station package. Radios and antennas are available for the following frequency bands:

2.5 GHz MMDS 3.5 GHz FWA 5.3 GHz U-NII 5.8 GHz U-NII There are also different antenna models available for 60 and 90 sectors. Radios and antennas are designed for mounting outdoors on tubular antenna masts or similar supports. Details are provided in Chapter 5. 070-20000340-01 Rev A 27 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW SUBSCRIBER SITE EQUIPMENT PacketWave equipment installed at the subscriber site consists of an subscriber Indoor Unit (a bridge/router between the wireless subnet and the subscribers computer or LAN), and an outdoor integrated radio/antenna unit. The two units are illustrated in Figure2-3 . There are four models of radios, for support of different frequency bands:

2.5 GHz MMDS 3.5 GHz FWA 5.3 GHz U-NII 5.8 GHz U-NII Radio/antenna units vary in size, depending on the frequency band. Each subscriber Indoor Unit can support any of the integrated radio/antenna units. (Of course, the radios frequency band must match that employed at the base station.) The radio/antenna unit is usually installed on the subscribers roof or under the eave, mounted either on a pole or to a flat surface. It is also possible to mount a radio/

antenna unit in a window if a suitable transmission path is available. 070-20000340-01 Rev A 28 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW There are three models of the Indoor Unit: the PacketWave 110, 120, and 130.

PA CKETWA VE SY STEM OVER VIEW THE PACKETW AVE SYSTEMS IP NETWORK The PacketWave System uses IP for the backhaul channel and the wireless channels. Overall, the system has the following network architecture, as shown in Figure2-5. The Base Station Units backhaul channel is part of a subnet which includes:

- A gateway to the outside world (Internet or private network).

- Access to a DHCP server (either the DHCP server or a DHCP relay agent must be on the same subnet as the BSUs backhaul interface).

- Access to a TFTP server identified by the DHCP server. Each wireless interface is the gateway for a subnet comprising itself and the subscriber Indoor Units with which it communicates, and perhaps some or all of the hosts at the subscriber sites. NOTE: A wireless interface can be configured for multiple subnets, if desired. Also, two or more wireless interfaces can be clustered in the same subnet. These options are discussed in detail later in this section. Subnets may be implemented at subscriber sites. Figure2-6 shows various options. 070-20000340-01 Rev A 210 CHA PTER 2.

PA CKETWA VE SY STEM OVER VIEW Figure2-6 PacketWave Subscriber Indoor Unit and Host IP Addressing 070-20000340-01 Rev A 212 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Address Assignment The PacketWave System supports DHCP (Dynamic Host Configuration Protocol), which manages IP address assignment for most interfaces in the PacketWave network. In the configuration of the DHCP server, the PacketWave System IP addresses must be fixedi.e., reserved for the specific units; they cannot be dynamically assigned. Specifically, PacketWave System IP addresses are distributed as follows:

The Base Station Unit receives the IP address of its backhaul interface from the DHCP server for its subnet. The Base Station Units wireless interfaces (WSS) are assigned IP addresses as part of the BSU configuration (using the WaveCenter Configuration Manager). Subscriber Indoor Units receive the IP addresses of their wireless interfaces from the DHCP server, via a DHCP relay agent in the Base Station Unit. Subscriber hosts can receive IP addresses in a variety of ways (see Figure2-6 ):

- From the BSUs DHCP server, via DHCP relay agents in the subscriber Indoor Unit and the Base Station Unit.

- From a DHCP server included in the subscriber Indoor Unit.

- From a DHCP server on the subscribers subnet.

- Using NAT (Network Address Translation), provided by the PacketWave Subscriber Indoor Unit or by a NAT router on the subscribers subnet.

- By manual entry at the hosts. Clustering Wireless Interfaces To enhance flexibility in the use of a particular IP address space, the PacketWave 1000 Base Station Unit allows multiple wireless interfaces to be assigned to the same subnet. This is done during BSU configuration using the WaveCenter Configuration Manager. SU-to-SU Bridging To make communication within the wireless subnets more efficient, the PacketWave 1000 Base Station Unit supports bridging between subscribers on the same subnet. SU-to-SU bridging is enabled or disabled during BSU configuration using the WaveCenter Configuration Manager. 070-20000340-01 Rev A 213 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Multiple Subnets on a Wireless Subsystem (WSS) To enable one wireless interface to support subscribers for two or more service pro-

viders, the PacketWave 1000 Base Station Unit allows multiple subnets to be assigned to the same wireless interface. This is done during BSU configuration using the Wave-

Center Configuration Manager. Figure2-7 shows multiple subnets on a wireless interface. Note that when a sub-

scriber Indoor Unit uses DHCP to request an address, neither the BSU (as DHCP relay agent) nor the DHCP server can determine from the request which subnet the SU should be assigned to. Therefore, IP and MAC addresses for all subscriber Indoor Units on the wireless system must be manually entered into the DHCP server. Figure2-7 Multiple Subnets on a WSS 070-20000340-01 Rev A 214 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Variable-Length Subnets (VLSM) The PacketWave System supports Variable-Length Subnet Masking (VLSM). The essential characteristic of VLSM is that any number of contiguous final bits in an IP address can define a subnet, meaning that subnets need not be limited to Class A, B, or C sizes. Using VLSM addressing techniques (such as recursive subnetting) can simplify routing and allow more efficient use of IP address space. Figure2-8 shows an example of VLSM addressing in a PacketWave network. A full discussion of VLSM is beyond the scope this manual, but detailed information can be found in numerous books and online sources. Figure2-8 VLSM on a PacketWave System 070-20000340-01 Rev A 215 Servers CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Each Base Station Unit requires access to DHCP and TFTP servers to boot up prop-

erly. Access to additional servers is required for the support of specific features. For additional information about PacketWave System servers, including the configu-

ration of a DHCP server, see Chapter 7. DHCP Server The DHCP server assigns IP addresses to all of the PacketWave interfaces except the Base Station Units wireless interfaces. It also tells each Base Station Unit and sub-

scriber Indoor Unit the name of its configuration file, its default gateway, and the addresses of other servers. Thus, the DHCP server is critical to the ability of PacketWave Base Station Units and subscriber Indoor Units to communicate with the rest of the Internet. Because DHCP is based on a broadcast request from a client, and the Base Station Unit is a DHCP client, the DHCP server or a DHCP relay agent must be located on the same subnet as the Base Station Units backhaul interface. TFTP Server For the PacketWave System, the main function of the TFTP server is to store the system configuration files, and download them on request. Each Base Station Unit and subscriber Indoor Unit requests its configuration file on hardware or software reboot

(cold or warm start). Each Base Station Unit and subscriber Indoor Unit stores its configuration in non-volatile memory. When it reboots, it downloads the latest configuration from the TFTP server if it is able to, and then makes any changes to its configuration based on a comparison of the downloaded configuration with the stored configu-

ration. If the device cannot successfully download its configuration from the TFTP server, it operates with its stored configuration. The TFTP server is also used to distribute software updates to Base Station Units and subscriber Indoor Units as follows:

The new software file is placed on the TFTP server. The configuration file for each unit to be downloaded is modified to specify the new software, and then re-saved on the TFTP server. Each unit to be downloaded is rebooted. During reboot, a unit gets its new con-

figuration file, learns that a new software file is specified, and downloads the software from the TFTP server. 070-20000340-01 Rev A 216 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW SNTP Server The Base Station Unit typically derives the time and date from an SNTP (Simple Network Time Protocol) server identified by the DHCP server. The BSU includes time zone and daylight savings time parameters which it applies to the received time and date as appropriate. NOTE: Alternatively, date and time can be set via the Web and SNMP interfaces. Subscriber Indoor Units use the BSU as their time server. DNS Server The DHCP server should identify an DNS server to be used in the resolution of Internet domain names. SMTP Server The PacketWave Base Station Unit can use email to announce events. If this feature is to be used, an SMTP (Simple Mail Transfer Protocol) server must be specified. System Log Server (Syslog) If a Syslog server is identified either by the DHCP server or in the BSU configuration, the Base Station Unit will log all events to the specified server using the standard Syslog protocol. SNMP Manager PacketWave Base Stations and subscriber Indoor Units include built-in SNMP (Sim-

ple Network Management Protocol) agents. These agents can be accessed by SNMP managers as specified in the system configuration. NOTE: PacketWave SNMP agents use SNMP v.2 syntax for objects. 070-20000340-01 Rev A 217 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Figure2-9 PacketWave Servers and Management Access 070-20000340-01 Rev A 218 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW CONFIGURATION AND MANAGEMENT SOFTWARE The PacketWave System includes the WaveCenter Configuration Manager for devel-

oping and maintaining the systems configuration files. It also includes a browser-

accessible Web GUI interface and an SNMP interface for real-time monitoring and management, plus a basic ASCII command line interface (CLI) for debugging/

troubleshooting. Figure2-9 shows the PacketWave Systems management access. Only configuration changes made using the WaveCenter Configuration Manager affect the PacketWave Systems configuration data base. While some configura-

tion can be performed via the Web and SNMP interfaces, these changes are lost if the configured equipment (Base Station or subscriber Indoor Unit) is rebooted. WaveCenter Configuration Manager The WaveCenter Configuration Manager (CM) is a Java-based application used to configure PacketWave base station and subscriber equipment. It runs on any of the following platforms:

Windows 98 Windows NT Windows 2000 Professional Linux Sun Solaris NOTE: The platform on which the WaveCenter Configuration Manager is run must include the Java Runtime Environment (JRE). JRE is included on the WaveCenter distribution CD. The Configuration Manager is used to create individual Base Station Unit and subscriber configuration files. These files are then stored on the systems TFTP server, from which they are downloaded automatically by Base Station Units and sub-

scriber Indoor Units as part of their boot-up processes. The PacketWave Configuration Manager has two parts: a Base Station Unit Config-

uration Manager and a Subscriber (CPE) Configuration Manager. Each consists of multiple menus which in combination allow full configuration of the PacketWave System components. A complete description of the Configuration Manager and its use is given in Chapter 6 of this manual. 070-20000340-01 Rev A 219 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW Web-Based GUI For real-time monitoring and limited configuration of the Base Station Unit and all of its subscriber sites, the Base Station Unit supports a graphical user interface (GUI) accessible via the IP network using a standard browser (currently, Netscape 4.74 or Internet Explorer 5.0). The Web interface includes network views, performance graphs, and event logs. Details of the Web interface are given in Chapter 8 of this manual. SNMP Agents For real-time monitoring and limited configuration, each Base Station Unit and sub-

scriber Indoor Unit includes a built-in SNMP agent with trap support. (In R1P1, all SNMP parameters are read-only). More information about SNMP capability in Chapter 8 of this manual. Command Line Interface An ASCII command line interface (CLI) provides a compact set of commands which are intended primarily for system troubleshooting by Aperto personnel or other qualified technicians. The CLI can be accessed via Telnet or directly through the Base Station Units front-panel RS-232 port. An overview of the CLI is given in Chapter 8 of this manual. 070-20000340-01 Rev A 220 CHA PTER 2. PA CKETWA VE SY STEM OVER VIEW SERVICE OFFERINGS AND QOS The PacketWave System is designed to give service providers extreme freedom in the definition of multiple services and the specification of quality-of-service (QoS) levels. Before configuring individual subscribers, services and QoS parameters need to be identified. Factors involved include:

Service Class, which may be:

- Best Effort (BE)

- Committed Information Rate (CIR)

- Constant Bit Rate (CBR) Type of Service (TOS) Overall and peak bandwidths Concepts of PacketWave Service Level Definition The PacketWave quality-of-service (QoS) capability is based on sets of classifiers and service flows, and links between the two, as shown in Figure2-10. A classifier is one or more layer 2 and/or layer 3 parameters which will identify a particular traffic flow. A service flow is a set of parameters which will determine the performance characteristics (QoS) of traffic assigned to that flow. When a classifier is defined, it is assigned to a specific service flow. Thus, any traffic meeting the classifier specifications will be transmitted according to the performance characteristics of its assigned service flow. Assigning Service Levels Service levels are assigned in the individual SU configuration files, allowing for max-

imum flexibility in differentiating service among subscribers. Details of service level specification are provided in Chapter 6. 070-20000340-01 Rev A 221 CHA PTER 2.

CELL SITE CONSIDERATIONS The planning of a wireless cell site is a complex task requiring the knowledge and skill of trained professionals. Location is of course a prime consideration, as are more technical factors such as interference management and lightning protection. Aperto expects that the cell site will be carefully thought out and professionally developed, and that recognized procedures and codes will be faithfully observed. When planning a cell site, take into account the following characteristics of the PacketWave System:

Base Station Location While line-of-sight paths are not required between PacketWave antennas at the base station and subscriber site, performance is improved when transmission paths are unobstructed. Do whatever is practical to minimize actual or potential transmission obstructions. Antenna and Radio Issues PacketWave base station antennas and radios are typically mounted on an antenna mast or tower, and include mounting brackets for attachment to tubular structures (pipes). If a mounting structure already exists, you will need to determine its suitability to the physical and radio characteristics of the PacketWave components. If no mounting structure exists or the existing one is not suitable, you will need to determine what type of mounting structure is appropriate, then obtain and install the structure. You will also need to determine the method by which antennas and radio will be mounted to the structure, and obtain appropriate hardware if the standard hard-

ware included with the PacketWave components is not appropriate. 070-20000340-01 Rev A 31 SUBSCRIBER SITE CONSIDERATIONS CHAP TER 3. SY STEM PLA NNING Locations of subscriber sites are determined by the subscribers, within the limits of the wireless cell. When implementing a subscriber site, consider the following:

Subscriber Indoor Unit Make sure the model chosen matches the sub-

scribers requirements for bridging/routing and host capacity. Radio Frequency Band Make sure the PacketWave radio/antenna unit operates in the wireless cells frequency band. Cabling You will need to supply cables for connecting the subscriber Indoor Unit to the outdoor radio/antenna, and for connecting the subscriber Indoor Unit to the subscribers computer or LAN. Table3-C identifies the cables that you will need to supply. (Cabling instructions are included in the PacketWave 100 Series Subscriber Equipment Installation and Operation manual.) More complete planning instructions for the subscriber site are included in the PacketWave 100 Series Subscriber Equipment Installation and Operation manual.

SY STEM PLA NNING When planning a PacketWave System, make sure you fully understand the systems IP networking principles and requirements as discussed in Chapter 2. Plan the network carefully; then document the various subnets and the individual IP addresses. A topological diagram, while not required, will provide the most readily understandable network documentation. Make sure that the network plan includes the following:

Base Station Units MAC address (needed for DHCP configuration). Subnet and IP address for the Base Station Units backhaul interface. Default gateway for the Base Station Units backhaul interface. Servers accessible by the Base Station Unit. Wireless subnets, and IP addresses for the Base Station Units WSS interfaces. MAC addresses of individual subscriber Indoor Units, matched to subscriber site (needed for DHCP configuration). IP address for each subscriber Indoor Units wireless interface. Default gateways for subscriber Indoor Units (Base Station Unit WSS inter-

faces). Subscriber LAN subnets and IP addresses, as appropriate. Instructions for configuring a DHCP server with the above information are provided in Chapter 7. CONFIGURATION PLANNING Each Base Station Unit and subscriber requires a separate configuration file which must be generated using the WaveCenter Configuration Manager. For basic operation, very simple configurations will suffice; the parameters which must be specified are:

Base Station Unit MAC address; WSS interface IP addresses and subnet masks; wireless channel center frequencies. Subscriber Indoor Unit MAC address; mode (bridge, router, or NAT);

model number. However, there are numerous other parameters which can be specified to aid in net-

work administration, to add features, or to adjust performance. Details are provided in Chapter 6 of this manual. 070-20000340-01 Rev A 35 CHAP TER 3. SY STEM PLA NNING Determine the amount of configuration appropriate for your network, and the specific options to be selected. Document the configuration requirements for all Base Station Units and subscribers. Service Level Planning Management of multiple service level offerings requires careful thought and signifi-

cant expertise in quality of service (QoS) issues and techniques. To maximize the flex-

ibility with which service levels can be defined and managed, the PacketWave System includes extensive configuration options related to the establishment of specific types and levels of service. If multiple service levels are to be offered, they must be defined in the Subscriber Unit

(CPE) configuration files. Principles of service level definition and implementation are discussed in Chapter 2; configuration details are presented in Chapter 6. 070-20000340-01 Rev A 36 4 INSTALLING BASE STATION UNITS The Base Station Unit (BSU) is a rack-mountable control unit that links up to six radios and their antennas to the core network through a WAN backhaul channel. It must be mounted indoors, protected from precipitation and temperature extremes. CAUTION: Make sure that the room in which Base Station Units are installed has temperature and humidity controls necessary to maintain the temperature between 32 and 104 F (0 and 40 C) and the humid-

ity between 10% and 90% noncondensing. MOUNTING The Base Station Unit occupies two vertical rack units (3.5 inches) in a standard 19-inch equipment rack. It includes integral mounting ears as part of the front panel, handles on the front panel near the mounting ears, and drawer slides on the sides of the unit. Air flow holes are located on the sides of the enclosure, with a pair of cooling fans on the rear panel. CAUTION: Make sure that the equipment is mounted so that adequate air flow around the BSUparticularly near the ventilation holes and fansis not blocked. Secure the front panel to the equipment rack using the appropriate hardware. 070-20000340-01 Rev A 41 CHA PTER 4. INSTA LLING BA SE STATION UN ITS FRONT-PANEL CONNECTIONS Other than the power connection, all connections to the Base Station Unit are made on the front panel, which is illustrated in Figure4-1. Figure4-1 BSU Front Panel Connecting the Radios to the BSU Connections from the outdoor radios to the Base Station Unit are described in Chapter 5 of this manual. Connecting the Backhaul Link The standard backhaul connection for the Base Station Unit is a 10/100-BaseTX link. This can be used for a range of different backhaul implementations, as shown in Figure4-2 . To make the backhaul connection:

Obtain or construct a Cat 5 cable of the required length, with a standard RJ45 plug on the BSU end and the appropriate connector on the other end. Insert one end of the cable with an RJ45 plug into the RJ45 socket labeled 100Base-T on the BSU front panel, as shown in Figure4-3. Connect the other end as appropriate for the particular backhaul implementa-

tion. 070-20000340-01 Rev A 42 CHAPTER 4.

INSTA LLING BA SE STATION UN ITS To properly identify wireless channel time slots, multiple colocated Base Station Units need to be synchronized to the same framing signal. This is done by intercon-

necting the units Sync connectors, as shown in Figure4-4 . When there are three or more Base Station Units, a main and alternate sync signal source for the framing sig-

nal should be chosen; with two Base Station Units, no alternate is necessary. Any Base Station Unit can be the source of a framing signal. If it is not receiving a framing signal at one of its Sync In ports, a BSU will transmit a framing signal through its Sync Out ports. Thus, when the primary framing signal source fails, the alternate signal source can take over immediately. To interconnect the multiple Base Stations:

1. Determine the Base Stations which will be the main and alternate sync signal sources. 2. For the main sync signal, construct a coaxial cable with a BNC connector at one end, a BNC T-connector for each Base Station Unit other than the main sync source, and a 50-ohm terminator at the other end. 3. For the alternate signal source, construct a coaxial cable with a BNC connector at one end, a BNC T-connector for each Base Station Unit other than the main and alternate sync sources, and a 50-ohm terminator at the other end. 4. Connect the Main Sync Out connector on the main sync signal source to the Main Sync In connectors on all other Base Station Units, as shown in Figure4-4 . 5. Connect the Alt Sync Out connector on the alternate sync signal source to the Alt Sync In connectors on all other Base Station Units except the main sync signal source, as shown in Figure4-4. 070-20000340-01 Rev A 44 CHAPTER 4.

INSTA LLING BA SE STATION UN ITS Connecting an External Reference Clock For timing, a Base Station Unit can use its own internal oscillator, or a 10 MHz signal from an external source. When multiple BSUs are colocated, it is a good idea to use an external source to facilitate synchronization. To connect an external source:

1. If it is not already present, install the reference source per the manufacturers instructions. 2. Construct a coaxial cable with a the required connector for the reference source at one end, a BNC T-connector for each BSU, and a 50-ohm termination at the other end. 3.

I NSTA LLING BA SE STATION UN ITS The Relay Switch connector on the Base Station Unit provides dry relay contacts for operating external equipment. It supports normally-open and normally-closed circuits, as shown in Figure4-6. CAUTION:

The alarm/control circuit connected to the relay switch should present a maximum current of 2 A at 30 V dc. It may be either normally open or normally closed. To connect to the alarm/control switch relay:

1. Design and implement the desired external alarm or control circuit. 2. Use between 28 and 14 AWG wire (2.5 mm maximum diameter) for connection to the BSU. Wire may be solid, stranded, or stranded with ferrule. 3. Verify whether the alarm/control circuit is normally closed or normally open. 4. For a normally-closed circuit, connect the leads to terminals 1 and 2. For a normally-open circuit, connect the leads to terminals 2 and 3. Make the connections by:

a. Loosening the screws above the wire holes, if necessary. b. Inserting the wires into the proper holes. c. Tightening the screws above the wire holes until the wires are held securely.

The port employs a DB-9 female connector and oper-

ates with the following parameters: 38.4K baud, 8 bits, 1 stop bit, no parity. To use the CLI through the craft port, connect the computer to the BSU front panel as shown in Figure4-7, using a null-modem (crossover) cable up to 25 feet in length. Operation of the CLI, which can also be accessed via Telnet, is discussed in Chapter 8 of this manual. To local computer

(command line interface only) Figure4-7 Connecting to the RS-232 Craft Port CONNECTING POWER The Base Station Unit may come with either an ac or dc power supply. There is no on-off switch on either model, so disconnecting the power cable or wires is the stan-

dard way to remove power from the BSU. Generally, it is a good idea to make power connections after all other connections have been made. However, any front-panel BSU connection can be disconnected and reconnected while power is on. 070-20000340-01 Rev A 48 CHAPTER 4. I NSTA LLING BA SE STATION UN ITS AC Power An ac power cord is supplied with the Base Station Unit.

Fuse holder ac cable connector Rear of BSU, left corner Figure4-8 AC Power Connection and Fuse Holder Fuse The ac power supply is protected by a fuse in a holder next to the power connector on the rear panel of the Base Station Unit, as illustrated in Figure4-8. For the US and other 120VAC power, the fuse is a 4 A, 250 V time-lag high-breaking fuse, 5 x 20 mm, such as the Schurter SPT 0001.2510. Should this fuse blow, determine and correct the cause (if possible). Then replace the fuse as follows:

1. Disconnect the BSUs power cord. 2. Use a flat-bladed screwdriver to lever up the tab at the bottom of the fuse-

holder and remove the fuse holder. 3. Remove the fuse from the clips that hold it, and verify that the fuse has blown. 4. Place a new fuse in the clips. 5.

dant -48 V dc power connections, plus two 4mm ground studs at the bottom edge of the rear panel. You can connect to one or two power sources, as desired. To connect to a dc power supply:

1. Use 12 AWG wire of no longer than 25 feet (8 m) for all power and ground connections. On the BSU end of each power and ground wire, install a crimp-

style ring lug of 0.3 inches (7.5 mm) or less in diameter to fit between the ter-

minal barriers. Make sure the wires are marked or color-coded to identify pos-

itive and negative connections. 2. Install a connecting wire from one of the GND lugs to a good earth ground. 3. Connect the positive (+) and negative (-) terminals of one of the BSUs dc power connectors to a -48 V dc power source, using a Phillips screwdriver to tighten the terminal posts on the ring lugs. Repeat for the other dc power con-

nector and power source, if desired. 4. If a redundant power supply is to be employed, repeat steps 3 and 4 for the other power source, terminal block, and ground lug. 070-20000340-01 Rev A 410 5 INSTALLING RADIOS AND ANTENNAS The PacketWave base station antennas and radios are designed for mounting outdoors on common antenna masts, and include mounting brackets for such mounting. Differ-

ent mounting hardware can be substituted as appropriate for your antenna support. INSTALLING THE ANTENNA MOUNTING SYSTEM Various antenna mounting systems can be used for the PacketWave base station. Choose a mounting system appropriate for your particular network and site, and fol-

low the manufacturers directions to install. If the antenna mounting system has a directional aspect (for example, a six-sided antenna mast), be sure to consider the physical sector locations when installing. CAUTION:

Be sure that the antenna mounting system is appropriate for the weights and wind-resistance of all of the antennas and radios to be installed on it, and for local environmental conditions. 070-20000340-01 Rev A 51 CHA PTER 5. INSTA LLING RAD IOS AN D ANTENN AS MOUNTING THE ANTENNAS AND RADIOS Before mounting the antennas, you need to know the compass directions and ele-

vation tilts appropriate for each sector. (The antennas have a beam width of 60 or 90 horizontal and 9 vertical). There are several antennas which may be used in a PacketWave system. Because of their different sizes and weights, the antennas do not all use the same mounting acces-

sories. The base station radio includes a rear-mounted bracket as shown in Figure5-1; the bracket accomodates a pole diameter of 1.5 inches (3.8 cm), 2 inches (5 cm) To mount an antenna:

1. Determine the mounting location for the antenna. 2. Orient the antenna vertically. 3. Using the mounting equipment provided, or other mounting hardware as desired, secure the antenna to the mast or other support. To mount a radio:

1. Determine the exact location for the radio. 2. Loosen the pole clamp bolt and open the pole clamp. 3. Orient the radio so that the F and RJ45 connectors are at the bottom. 4. Close the pole clamp around the pole. 5. Adjust the direction and elevation of the radio/antenna unit. 6. Tighten the pole clamp bolt until the radio/antenna unit is secured in position.

I NSTA LLING RAD IOS AN D ANTENN AS RUNNING THE RADIO CABLES Connections to the radio include two RF jumper connections up to the antenna and two connections down to the Base Station Unit. Radio to Antenna The radio is connected to the antenna by two cables. One end of each is attached to the radio internally, and the other terminates with a male N connector, as shown in Figure5-2 . To connect the radio to the antenna:

1. Connect the cables from the radio to the appropriate connectors on the antenna. 2. Apply a silicone sealant or other weatherproofing to the connections as desired. Radio to Base Station There are two cables that connect each radio to its Base Station Unit: a radio signal cable (which also carries dc power) and a control cable. These cables run from out-

door radios to the indoor BSU, so a suitable cable run and building entry point must be identified, as discussed in Chapter 3. Connections to the BSU are illustrated in Figure5-3 ; Connections to the radio are illustrated in Figure5-4. For these outdoor-to-indoor connections, the order of the steps in the installation procedure will vary depending on a number of factors, including site particulars and installers preferred practice. For example, in some cases it may be best to run unterminated cable and then attach connectors; in others it may be more effi-

cient to attach one or both connectors to the cable before running it. Also, cable dressing at various locations may be best performed at different points in the pro-

Creating the BSU and subscriber (CPE) configuration files and placing them on the TFTP server is half of the PacketWave system configuration. The other half is the configuration of the IP network, including the DHCP server, described in Chapter 7. INSTALLING THE WAVECENTER CONFIGURATION MANAGER The WaveCenter Configuration Manager is provided on CD as part of the BSU pack-

age. You can load the WaveCenter Configuration Manager onto a computer running any of the following operating systems:

Windows 98 Windows NT Windows 2000 Professional Linux Sun Solaris Whatever the platform, it will need to have the Java Runtime Environment (JRE) installed on it. If the JRE is not already present, it can be installed from the Wave-

Center CD. 070-20000340-01 Rev A 61 CHA PTER 6. BSU AND S UBSCR IBER CON FIGU RATION Depending on the particulars of your network, it may be a good idea to run the WaveCenter Configuration Manager on the same computer that provides the systems TFTP server. If you run the Configuration Manager on a different computer, you must be able to move the files created by the Configuration Manager to the TFTP server computer. To install the WaveCenter Configuration Manager:

1. Place the CD in the CD-ROM drive and view the contents. Note that there is a cm folder/directory, which contains the Configuration Manager installation files, and a jre folder/directory, which contains the executable file for the Java Runtime Environment. 2. If the computer does not already have the Java Runtime Environment installed, open the jre folder/directory and run the executable file (jre<version>.exe). 3. Open the cm folder/directory; then open the appropriate folder/subdirectory for your platform and run the appropriate setup file. For example, for a Windows system open the win32 folder and run setup.exe. 4. Follow the prompts in the installation wizard. 5. When installation has been completed, a WaveCenter Configuration Manager icon will have been placed on the desktop. Double-click this icon to launch the WaveCenter Configuration Manager. 070-20000340-01 Rev A 62 CHA PTER 6. BSU AND S UBSCR IBER CON FIGU RATION HOW THE WAVECENTER CONFIGURATION MANAGER WORKS The WaveCenter Configuration Manager is used to create a separate configuration file for each Base Station Unit and each subscriber in the system. Each base station unit and subscriber site (CPE) must have a valid configuration file in order to function. BSU and Subscriber Branches The WaveCenter Configuration Manager consists of separate Base Station Unit and subscriber (CPE) branches, accessed by clicking the BSC and SU (CPE) icons shown in Figure6-1. To configure a Base Station Unit, click on the BSC icon. To configure subscriber equipment, click on the subscriber Indoor Unit (CPE) icon.

CHA PTER 6. BSU AND S UBSCR IBER CON FIGU RATION Managing Configuration Files Before using the WaveCenter Configuration Manager, be sure you understand the principles of configuration file management discussed below. Opening and Loading Files When you click on the BSU or subscriber Indoor Unit (CPE) icon on the WaveCenter Configuration Manager home screen, a new (blank) configuration file is opened with the default parameters. You can then load an existing file by selecting File Open from the menu bar, or the file open icon on the toolbar. The Configuration Man-

ager will let you browse for the desired file. NOTE: Some screens have a new instance icon on the right side. This icon does not cause a new configuration file to be opened; rather, it causes a new instance to be opened, and is displayed only on pages which can be configured multiple times for multiple instances (such as multiple SNMP managers; see Figure6-2). Saving Files There are two methods for saving configuration files, as identified in Table6-A:

Selecting File Save as from the page menu line. The Configuration Manager will prompt for a file name. Clicking on the Generate BSC Config or Generate Configuration File (CPE) button. The Configuration Manager will prompt with the suggested file name in the format bsc_<MACaddress>.cfg or cpe_<MACaddress>.cfg, using the MAC address entered during configuration. See the discussion of file names below. NOTE: Some screens have a page save icon on the right side. This icon does not cause the configuration file to be saved; rather, it causes the current instance to be added to the configuration file which is being created or modified. The page save icon is displayed only on pages which can be configured multiple times for multiple instances (such as multiple SNMP managers; see Figure6-2). File Names Configuration files are required to have unique names so that each BSU and sub-

scriber Indoor Unit can download the correct configuration file from the TFTP server. Table6-B identifies the naming convention suggested by Aperto, which uses MAC addresses to guarantee uniqueness. These are the default names used when you click on the Generate BSC Config or Generate Configuration File button, as described above. While the naming convention identified in Table6-B is recommended, it is not required. You can use any other format you wish, as long as the names are unique. 070-20000340-01 Rev A 66 CHA PTER 6. BSU AND S UBSCR IBER CON FIGU RATION Table6-B Suggested Convention for Naming Configuration Files Configured Entity File Name Format Example Base Station Unit bsc_<MACaddress>.cfg Subscriber cpe_<MACaddress>.cfg bsc_00013b0002e4.cfg

(for MAC 00:01:3b:00:02:e4) cpe_00013b00025d.cfg

(for MAC 00:01:3b:00:02:5d) Storage Location To be accessed by the Base Station Units and subscriber Indoor Units when they boot, the configuration files must be specified in the DHCP servers configuration file and stored in the default directory (typically, \tftpboot) of the TFTP server. You can save directly to that directory when creating the configuration files, or save to a different location and then transfer the files before booting the configured units. Configuration Template Files It will often be efficient to create generic configuration files which can be used as templates when adding new BSUs, WSSs, or subscribers. You create and save a configuration template the same way you create and save a con-

figuration file, but save it with a descriptive file name rather than a file name linking it by MAC address to a specific unit. Then, when you want to use the template as the basis for a new configuration file, you load the template, make any changes necessary, and save the file using the correct file name for the new unit. NOTE: Similarly, you can base a new configuration file on an existing configuration file by loading the existing file, editing it, and saving it using the proper file name for the new unit. Downloading Configuration Files After the configuration files have been created and stored on the TFTP server, the con-

figured devices need to be booted up. (The Base Station Unit must be operational when a subscriber Indoor Unit is initialized, or the initialization will fail.) The booted device will then automatically download its configuration from the TFTP server. Each Base Station Unit and subscriber Indoor Unit stores its configuration in non-volatile memory. When it reboots, it downloads the latest configuration from the TFTP server if it is able to, and then makes any changes to its configuration based on a comparison of the downloaded configuration with the stored configu-

ration. If the device cannot successfully download its configuration from the TFTP server, it operates with its stored configuration. 070-20000340-01 Rev A 67 CHA PTER 6.

1. Click on the Classifier tab and then the Upstream tab so that the screen illus-

trated in Figure6-16 is displayed. 2. Assign upstream traffic to a service flow as follows:

a. Specify the parameter(s) that will define the classifier. b. Choose the service flow to which traffic matching this classifier will be directed by selecting from the Service Flow Reference menu. c. Click on the save instance icon when done. 3. Click on the Downstream tab so that the screen illustrated in Figure6-17 is displayed. Assign downstream traffic to a service flow as follows:

a. Specify the parameter(s) that will define the classifier. b. Choose the service flow to which traffic matching this classifier will be directed by selecting from the Service Flow Reference menu. c. Click on the save instance icon when done. 4. To define another set of upstream and downstream classifiers, click on the new instance icon. Note that the Classifier Reference field will increment. a. Click on the Upstream tab, choose the service flow to which traffic matching this classifier will be directed by selecting from the Service Flow Reference menu, alter parameters as desired, and click on the save instance icon. b. Click on the Downstream tab, choose the same service flow as for upstream traffic from the Service Flow Reference menu, alter parameters as desired, and click on the save instance icon. 5.

BSU AND S UBSCR IBER CON FIGU RATION OTHER CONFIGURATION METHODS Only configuration changes made using the WaveCenter Configuration Manager can affect the PacketWave Systems configuration file on the TFTP server. A limited set of configuration changes can be made in real time via the Web and SNMP interfaces. But such changes are not recorded in, and cannot be saved to, the configuration files on the TFTP server. When the configured equipment (Base Station Unit or subscriber Indoor Unit) is rebooted, it will revert to the parameters in the stored configuration file, and all changes made via the Web interface or SNMP will be lost. Therefore, configuration changes via the Web Interface or SNMP are recommended only for testing and troubleshooting purposes. Should a configuration change need to be made permanent, you must use the WaveCenter Configuration Manager to update the relevant configuration file on the TFTP server. NOTE: If a configuration change is made to operating parameters using the Web or SNMP interface, and then duplicated using the CM and saved to the TFTP server, the change will essentially survive a reboot. This is a way to make permanent con-

figuration changes without immediately rebooting the system. 070-20000340-01 Rev A 639 CHA PTER 6. BSU AND S UBSCR IBER CON FIGU RATION 070-20000340-01 Rev A 640 CHAPTER 7. NETWORK CONFIGURATION AND START-UP Figure 7-1 PacketWave System Servers Required and Recommended Servers Make sure that the Base Station Unit can access the following servers:

DHCP Server The server from which the Base Station Units and subscriber Indoor Units obtain:

- IP addresses

- Subnet masks

- Default gateways

- TFTP server IP address

- Other server IP addresses

- BSU and SU configuration file names NOTE: If the DHCP and the BSU are not on the same subnet, the BSUs subnet must include a DHCP relay agent to pass the BSUs DHCP requests to the proper DHCP server. Also, subscriber Indoor Units can collectively be assigned a different DHCP server than the one used by the BSU. 070-20000340-01 Rev A 72 CHAPTER 7. NETWORK CONFIGURATION AND START-UP TFTP Server The server from which the Base Station Units and subscriber Indoor Units download configuration files. SNTP Server A Simple Network Time Protocol server is recommended for synchronizing the PacketWave Base Station Units date and time with other systems on the network. (If there is no SNTP server, the Base Station Units date and time must be set via the Web interface.) NOTE: Subscriber Indoor Units obtain the date and time from the BSU. Whenever the BSUs date/time is changed, it downloads the new date/time to all subscriber Indoor Units. DNS Server Access to a DNS server is necessary for the resolution of Internet domain names. Optional Servers Depending on the features and functions to be implemented, additional servers may be required. These servers can be identified in the DHCP server configuration or in the BSU configuration. NOTE: If different servers of a particular type are identified, the server identified in the DHCP configuration will prevail. SMTP Server A Simple Mail Transfer Protocol server is required for the emailing of event alerts. (Alternatively, this server can be identified in the BSU configuration.) Syslog Server A syslog server may be specified for logging of event mes-

sages from the Base Station Units. (Alternatively, this server can be identified in the BSU configuration.) DHCP Server for CPE A different DHCP server than the one used for the BSU can be specified for Subscriber Indoor Units. SNMP Managers All Base Station Units and subscriber Indoor Units include SNMP (Simple Network Management Protocol) agents which can be accessed by an SNMP manager for monitoring and limited configuration. The SMTP, Syslog, and CPE DHCP servers can be identified via the WaveCenter Configuration Managers BSU MAIN IP Servers screen. (The SMTP and Syslog servers can also be specified in the DHCP servers configuration file.) The SNMP managers are identified via the BSU SNMP and CPE SNMP screen 070-20000340-01 Rev A 73 CHAPTER 7. NETWORK CONFIGURATION AND START-UP Preparing the TFTP Server The PacketWave System uses the TFTP server for storing files and downloading them to Base Station Units and subscriber Indoor Units on request. Any third-party or pub-

lic domain TFTP server may be used. Ensure that configuration files for all Base Station Units and subscriber Indoor Units are stored in the default directory (typically \tftpboot) of the TFTP server, and that the TFTP server is running. Configuring the DHCP Server A variety of DHCP servers are available. Their configurations follow the same general principles, but vary in implementation, terminology, and user interfaces. DHCP con-

figuration should be performed by personnel knowledgeable about both DHCP in gen-

eral and the particular DHCP server to be used. Whichever DHCP server is employed, it should be configured to include the parameters identified in Table 7-A. CAUTION:

Take special care to ensure that the BSU and subscriber configu-

ration file names entered in the DHCP configuration are exactly the same as the files created using the WaveCenter Configuration Manager and stored on the TFTP server. A newly-installed unit will not be able to operate properly if it cannot locate and down-

load its configuration file. Table 7-A DHCP Configuration Requirements Servers Subnets (Scopes) Each Base Station Unit Each Subscriber Indoor Unit Required: TFTP Recommended: SNTP, DNS Optional: SNMP, SMTP, POP3 Subnets / Subnet Masks Routers / Gateways Hardware Ethernet / MAC address Fixed IP address for backhaul interface configuration file name Hardware Ethernet / MAC address Fixed IP address for wireless interface configuration file name Subscriber Hosts IP addresses if the subscriber Indoor Unit functions as a bridge DNS server if the subscriber Indoor Unit functions as a NAT router 070-20000340-01 Rev A 74 CHAPTER 7. NETWORK CONFIGURATION AND START-UP SYSTEM START-UP Once all of the configuration files have been created, start the PacketWave System by performing the following steps:

1. Verify that all of the configuration files have been saved in the default directory on the TFTP server. 2. Verify that the TFTP server is running and accessible. 3. Verify that the DHCP server has been configured for network addresses and for all BSUs and subscribers. 4. Verify that the DHCP server is running and accessible. 5. Boot the Base Station Unit. It will download its configuration, obtain its IP address, and initialize automatically. 7. 6. When the Base Station Unit has finished initializing, boot the subscriber Indoor Units. Initialize each subscriber Indoor Unit using the CPE Installation Tool, as described in the PacketWave 100 Series Subscriber Equipment Installation and Operation manual. When a subscriber Indoor Unit has been initialized, it will download its configuration, obtain IP addresses, and join the network. ADDING BASE STATION UNITS AND/OR SUBSCRIBERS To add one or more Base Station Units and/or subscribers to an existing cell:

1. Launch the WaveCenter Configuration Manager. 2. Use the Configuration Manager to create configuration files for the new device(s) as described in Chapter 6. 3. Save or copy the configuration file(s) to the default directory of the TFTP server. 4. Add the required information about the device(s) in the DHCP servers config-

uration file. 5. Boot the new devices. 070-20000340-01 Rev A 75 CHAPTER 7. NETWORK CONFIGURATION AND START-UP OTHER CONFIGURATION METHODS Only configuration changes made using the WaveCenter Configuration Manager affect the PacketWave Systems configuration data base. A limited set of configuration changes can be made in real time via the Web and SNMP interfaces, but such changes are not permanently stored. When the configured equipment (Base Station Unit or subscriber Indoor Unit) is rebooted, it will revert to the stored configuration, and all changes made via the Web interface or SNMP will be lost. Therefore, configuration changes via the Web Interface or SNMP are recommended only for testing and troubleshooting purposes. Should a permanent configuration change need to be made, you must use the WaveCenter Configuration Manager to update the relevant configuration files on the TFTP server. 070-20000340-01 Rev A 76 8 MANAGEMENT INTERFACES The PacketWave system supports real-time monitoring and limited on-the-fly con-

figuration changes via a Web-browser-accessed Graphical User Interface (GUI) and SNMP. There is also a simple command line interface (CLI) for basic troubleshooting and debugging. WEB INTERFACE (GUI) Each Base Station Unit and Subscriber Unit includes a Java-based graphical user interface (GUI) which runs on a standard Web browser (Netscape 4.74 or higher, or Internet Explorer 5.0). Functions of the Web GUI include:

Viewing network topology. Monitoring status and performance. Reviewing configuration. Making basic configuration changes. Resetting Base Station Units, BSU wireless interfaces (WSSs), and subscriber Indoor Units. 070-20000340-01 Rev A 81 CHA PTER 8. MAN AGEMENT I NTERF ACES Accessing the Web Interface To access the graphical user interface:

1. Establish a connection and open your Web browser. 2. Enter the URL, http://<BSU IP address>/bsc.htm. 3. Respond to the user name prompt with Aperto and to the password prompt with Aperto. NOTE: The user name and password are case-sensitive, so be sure to capitalize the A in Aperto. 4. If the browser prompts that it needs to load a plug-in, allow it to do so. 5. Wait for the Web interface home page to open, as shown in Figure8-1. The Web GUI pages share the basic elements identified in Figure8-1 . Using the Base Station Units Web GUI When you open the BSUs Web GUI, you are at the BSU Home Page shown in Figure8-1 . A main menu and submenus allow you to navigate easily among the var-

ious BSU pages. Network Views From the BSU Home Page, you can view the BSU and its wireless interfaces. Hyper-

links allow you to navigate through the BSU connections as indicated in Figure8-1 through Figure8-3. The first time you select the Cell View page (Figure8-3), your browser may prompt that it wants to download Java applets. Click on the OK button to allow the download. The applets will then be cached in the browser, so downloading will not be required in the future. The connectivity views provide a quick way to identify the configured Base Station Units, sectors (WSS), and subscribers, and to check their status. The arrows pointing to the subscriber Indoor Units in Figure8-1 and Figure8-2 indicate wireless channel status: green if good or red if down. Color-coding of the cell view, shown in Figure8-3, is indicated by the legend on the cell view page. Status indications on the topology views are updated dynamically every 30 seconds. 070-20000340-01 Rev A 82 CHAP TER 8.

INTENDED AUDIENCE FOR THIS MANUAL This manual is intended primarily for subscriber equipment installers. It also includes information of use to subscribers, including a discussion of the Web GUI. Installation of radio equipment involves numerous factors requiring considerable expertise. It is assumed that equipment installers are professionals with a full under-

standing of the principles and standard practices and procedures of cell site installa-

tion, with all relevant safety requirements, and with applicable local building codes. 070-20000330-01 Rev A viii GENERAL CAUTIONS AND WARNINGS CHAPTER 1. Observe the following when installing or operating any PacketWave System compo-

nents. All outdoor installation, including equipment mounting and cabling, should be performed by trained microwave radio technicians familiar with usual and customary practices and procedures. Always use quality componentsincluding cables, connectors, mounts, etc.spe-

cifically rated for your particular environmental conditions and system performance requirements. Always use appropriate tools, and follow the instructions of the tool manufacturers. Observe all applicable local building codes. Observe all customary and mandatory safety requirements when installing and operating PacketWave equipment. Because Aperto Networks cannot be responsible for improper installation or use of its equipment, failure to follow these and other published cautions and warnings may void your equipment warranty. 070-20000330-01 Rev A ix CHAPTER 1. 070-20000330-01 Rev A x 1 QUICKSTART GUIDE This chapter outlines the basic procedure for installing PacketWave 100 Series Subscriber Equipment and putting it into operation. It identifies the minimal require-

ments for getting the equipment up and running, and assumes that configuration using DHCP and WaveCenter Configuration Manager has been performed as described in the PacketWave 1000 Base Station Unit manual. WARNING: This QuickStart Guide assumes that outdoor installation proce-

dures will be performed by qualified professionals following all safety and other requirements and acting in accordance with standard practices and procedures. Failure to meet safety requirements and/or non-standard practices and procedures could result in personal injury and/or damage to equipment. All of the instructions presented in this chapter are discussed in more detail in subse-

quent chapters of this manual. Step 1. Prepare for Installation A. Before visiting the subscribers site:

i. Make sure that the necessary system configuration has taken place (as described in the PacketWave 1000 Base Station Unit manual). ii. Make sure that the systems DHCP and TFTP servers are running. iii. Verify that the subscriber configuration file has been created and saved on the TFTP server. iv. Verify that the DHCP server has been configured with the subscribers IP and MAC addresses and its configuration file name. 070-20000330-01 Rev A 11 CHAPTER 1. QUICKSTART GUIDE B. At the subscribers site:

i. ii. Identify the location for the Indoor Unit (bridge/router). Identify an appropriate location for mounting the Outdoor Unit. In most cases, the unit should be pointed at the base station with the least possible obstruction iii. Determine the cable path between the Indoor Unit and the Outdoor Unit. Maximum cable length is 165 feet (50 m). Step 2. Install the Outdoor Unit (Radio/Antenna) A. If a mounting pole or other support is to be employed, install it in the chosen loca-

tion, following standard procedures and local building codes. The Outdoor Units mounting bracket accommodates diameters of 1.5 inches, 2 inches, or 5 cm. B. Mount the Outdoor Unit to the support or to the building. Step 3. Install the Indoor Unit (Bridge/Router) A. To start, in most cases, the Indoor Unit should be temporarily placed close to the Outdoor Unit to facilitate antenna alignment process. When the installation of the-

Outdoor Unit is complete, move the Indoor Unit to its permanent location. WARNING:

For proper cooling, the Indoor Unit must be installed in the upright position, with adequate air flow around and through it. Make sure the Indoor Unit is located near an electrical power outlet or power extension cord will be needed. B. Assuming that the Indoor Unit is located at a temporary location, run spare radio signal and control cables between the Outdoor and Indoor Units.

- Radio signal cable (quad shield coaxial, male F connectors) Radio RF connectors on the Outdoor and Indoor Units.

- Radio control cable (shielded outdoor Cat 5, male RJ45 connectors) Radio Control connectors on the Outdoor and Indoor Units. The Radio Control interface on the Indoor Unit has the same physical appearance as the 10/100Base-T interface. Make sure you connect to the right one. 070-20000330-01 Rev A 12 Step 4. Initialize the Subscriber Equipment CHAPTER 1. QUICKSTART GUIDE A. Connect the power cable between the Indoor Unit and a wall outlet. B. Perform antenna alignment procedure (see addendum on this subject). C. If the Indoor Unit is located at a temporary location, move the Indoor Unit to its permanent location. WARNING:

For proper cooling, the Indoor Unit must be installed in the upright position, with adequate air flow around and through it. D. Use the permanent radio signal and control cables to connect the Outdoor Unit to the Indoor Unit.

- Radio signal cable (quad shield coaxial, male F connectors) between Radio RF connectors on the Outdoor and Indoor Units.

- Radio control cable (shielded outdoor Cat 5, male RJ45 connectors) between Radio Control connectors on the Outdoor and Indoor Units. For permanent outdoor-to-indoor connections, the order of the steps in the instal-

lation procedure will vary depending on a number of factors, including site particulars and installers preferred practice. For example, in some cases it may be best to run unterminated cable and then attach connectors; in others it may be more efficient to attach one or both connectors to the cable before running it. See Chapter 4, Outdoor Unit Installation for more details. Step 5. Configure Subscriber Hosts A. Connect the subscribers computer(s) to the 10/100Base-T interface on the Indoor Unit, using a straight Ethernet cable for connection to a hub or a crossover Ether-

net cable for connection directly to a computer. B. Typically, the only other thing necessary to connect a subscriber host computer to the PacketWave network and beyond is to configure the hosts TCP/IP to obtain its IP address using DHCP. Instructions should be available using the computers online help 070-20000330-01 Rev A 13 CHAPTER 1.

antenna), and an Indoor Unit (bridge/router), as shown in Figure 2-1. Outdoor Unit

(Radio/Antenna) Indoor Unit

(Bridge/Router) Figure 2-1 PacketWave Subscriber Equipment 070-20000330-01 Rev A 21 CHAPTER 2. OVERVIEW Outdoor Unit The outdoor portion of the subscriber equipment consists of a single unit containing the radio and antenna. Different models support various frequency bands:

2.5 GHz MMDS 3.5 GHz FWA 5.3 GHz 5.8 GHz U-NII The radio/antenna unit installed at the subscriber site must match the frequency band employed at the base station. 2.5 GHz MMDS 3.5 GHz FWA 5.3 GHz or 5.8 GHz U-NII Figure 2-2 Subscriber Outdoor Units As shown in Figure 2-2, sizes of the antennas vary with the frequency band, from approximately 9 inches square to approximately 13 inches square. Outdoor units mount easily on a home or office roof, under the eave, or even in a properly-situated window. The subscriber antennas are directional, with a beam width of 17 to 20 horizontally and vertically depending on frequency. The width of this beam, combined with the width of the base station antenna beam, means that only rough pointing of the antenna is needed for establishing a wireless link, though accurate pointing is important for maximum signal quality. Depending on distance, a line-of-sight path may not be required for establishment of a wireless link between the subscriber and the base station. PacketWaves OptimaLink technology minimizes the effects of obstructions in the path between the subscribers antenna and the base station antenna. 070-20000330-01 Rev A 22 CHAPTER 2. OVERVIEW Indoor Unit The PacketWave 100 Series Indoor Unit is a bridge/router which provides the link between the subscribers computer(s) and the outdoor radio/antenna for the wireless service. The first available model, the PacketWave 130 supports bridging and NAT modes. IP routing will be supported in the next major software release. On the radio/antenna side, the Indoor Unit has two interfaces:

A port for wireless traffic (which also provides power to the Outdoor Unit). A port for controlling the radio/antenna. On the subscriber side, the Indoor Unit has an auto-negotiating 10/100Base-T Ethernet port. The Indoor Unit plugs into a standard ac wall plug (120 or 220 volts). A power cord with transformer is provided with the unit. Bridging Mode NAT Mode Figure 2-3 PacketWave 130 Indoor Unit 070-20000330-01 Rev A 23 Software CHAPTER 2. OVERVIEW Subscriber equipment is provisioned using the WaveCenter Configuration Manager, as described in the PacketWave 1000 Base Station Unit Installation, Configuration, and Operation manual. On boot-up, the indoor unit downloads its configuration from the base stations TFTP server. At the same time, it downloads address and host infor-

mation from the base stations DHCP server. The PacketWave 100 Series subscriber equipment includes the following management software:

CPE Installation Tool See addendum on antenna alignment procedure Web GUI Each Indoor Unit includes a graphical user interface (GUI) which can be accessed via a standard Web browser, either directly or through the Base Station Units Web GUI. Direct access to the Web GUI is available to the ser-

vice providers and can be made available to subscribers as well. Use of the Web GUI is described in Chapter 7. SNMP Agent Each Indoor Unit includes an SNMP agent which can be accessed via a standard SNMP manager, either directly or through the Base Station Units proxy agent. SNMP capability is described in Chapter 7. Command Line Interface A limited command line interface (CLI) to the Indoor Unit can be accessed via telnet. Use of the CLI is described in Chapter 7. PacketWave Indoor Units also include servers and other networking functionality:

DHCP Server PacketWave 130 Indoor Units include a Dynamic Host Configuration Protocol (DHCP) server for local address management. DHCP Relay Agent PacketWave 130 Indoor Units include a Dynamic Host Configuration Protocol (DHCP) relay agent for passing DHCP communications to the Base Station Unit. NAT Server PacketWave 130 Indoor Units include a built-in NAT (Network Address Translation) server. 070-20000330-01 Rev A 24 3 SITE PLANNING There are three basic site-planning issues which must be decided before you begin installation:

Location of the Indoor Unit (bridge/router). Location and mounting method of the Outdoor Unit (radio/antenna). Cable path between the Indoor Unit and the Outdoor Unit. LOCATION OF THE INDOOR UNIT (BRIDGE/ROUTER) Typically, the Indoor Unit is located near the subscribers hub or computer. However, the Ethernet cable to the local computer or hub can be up to 330 ft (100 m) in length. CAUTION: Make sure that the Indoor Unit is installed in a room with tem-

perature and humidity controls such that the temperature remains between 32 and 104 F (0 and 40 C) and the humidity remains between 10% and 90% noncondensing. 070-20000330-01 31 LOCATION OF THE OUTDOOR UNIT (RADIO/ANTENNA) CHAPTER 3. SITE PLANNING For optimal wireless channel performance, it is advantageous to locate the Outdoor Unit (radio/antenna) where it has the least-obstructed path to the base station antenna. If a line-of-site path is available, locate the Outdoor Unit where the path is least likely to be affected by such obstructions as blowing branches, seasonally changing foliage, etc. If a clear line-of-site path is not available, choose a path that minimizes obstruc-

tions. Fine-tuning of the antenna pointing is performed using the CPE Installation Tool software, as described in Chapter 6 of this manual. Other factors to consider when choosing a location for the Outdoor Unit include:

Distance to the Indoor Unit Locate the Outdoor Unit so that cables to the Indoor Unit will be no longer than 165 feet (50 m). Cable routing Consider how cables from the Outdoor Unit cables will enter the building. Accessibility If possible, choose a location that is relatively accessible, which will simplify installation and any adjustment or repair that might be nec-

essary in the future. Mounting method The antenna/receiver includes an adjustable bracket for mounting the unit on a pole that is 1.5 inch, 2 inches, or 5 cm in diameter. For other mounting options (under an eave or on a chimney, for example), mount-

ing hardware may be adapted as desired. Any alternate mounting method should allow adequate adjusting of the antenna direction, both horizontally and vertically. 070-20000330-01 32 CABLES AND CABLE PATH CHAPTER 3. SITE PLANNING For subscriber equipment installation, you will need the cables and connectors indi-

cated in Table 3-A. Table 3-A Subscriber Site Cable Requirements

Choose the path along which the cables will run between the Indoor Unit and the Out-

door Unit, keeping in mind that a radio signal cable length should be less than 165 feet (50 m). Carefully consider both the outdoor and indoor portions of the cable run. Decide how the cable run will be secured, how it will enter the building, and whether it will include wall jacks. Consider all local building codes and standard construction practices when planning the cable path. SUBSCRIBER LAN/COMPUTER If the Indoor Unit is functioning in NAT mode, addresses on the local subnet (i.e., LAN) will not be visible beyond the subscribers subnet. The Indoor Unit will auto-

matically become a DHCP server for the subscribers subnet. In addition, in default setting, the Indoor Units DHCP server will use the DNS server address supplied by the systems DHCP server to resolve network addresses. 070-20000330-01 33 CHAPTER 3. SITE PLANNING 070-20000330-01 34 4 OUTDOOR UNIT INSTALLATION In most cases, the installation of the Outdoor Unit should be performed before the installation of the Indoor Unit (see Chapter 5). Since the Outdoor Unit must be con-

nected to the Indoor Unit to align the antenna, the Indoor Unit should be temporarily placed close to the Outdoor Unit to facilitate this process. When the installation of the Outdoor Unit is complete, the Indoor Unit can be moved to its permanent location. INSTALLATION REQUIREMENTS You will need the following tools and supplies when installing the Outdoor Unit:

Drill (for cable entry through walls, etc.) Phillips screwdriver Wrench Cabling tools Spare radio signal and control cables with connectors (each 30 feet or longer) Cable ties, staples, or clamps for dressing cables Silicone sealant You will also need the following cables and connectors:

Coaxial cable (quad shield) and two male F connectors Shielded Cat 5 cable (outdoor rated) and two RJ45 male connectors Ethernet cable with RJ45 male connectors (straight-through for connection to hub, or crossover for connection to computer) 070-20000330-01 Rev A 41 CHAPTER 4. OUTDOOR UNIT INSTALLATION MOUNTING THE OUTDOOR UNIT (RADIO/ANTENNA) Subscriber Outdoor Units are designed for mounting on a pole or antenna mast with a diameter of 1.5 inch, 2 inches, or 5 cm, using a rear-mounted bracket as shown in Figure 4-1. To mount an Outdoor Unit on a pole:

1. Loosen the pole clamp bolt and open the pole clamp. 2. Close the pole clamp around the pole. 3. Adjust the direction and elevation of the radio/antenna. 4. Tighten the pole clamp bolt until the Outdoor Unit is secured in position. Figure 4-1 Outdoor Unit Mounting Bracket Other mounting options, such as under an eave or in a window, can also be employed. In such cases, appropriate mounting hardware must be obtained. RUNNING CABLES BETWEEN OUTDOOR AND INDOOR UNITS As described in Chapter 2, there are two cables that connect the Outdoor Unit to the Indoor Unit:

A quad shield coaxial cable for the subscriber signal (which also provides 12 V dc power to the Outdoor Unit). A shielded Cat 5 cable for controlling the Outdoor Unit. The connectors on the Outdoor Unit are located on the back, at the bottom of the radio enclosure. 070-20000330-01 Rev A 42 CHAPTER 4. OUTDOOR UNIT INSTALLATION These cables run from outdoors to indoors, so a suitable cable run and building entry point must be identified, as discussed in Chapter 3. For these outdoor-to-indoor connections, the order of the steps in the installation procedure will vary depending on a number of factors, including site particulars and installers preferred practice. For example, in some cases it may be best to run unterminated cable and then attach connectors; in others it may be more effi-

cient to attach one or both connectors to the cable before running it, or to use a pre-assembled cable. Also, cable dressing at various locations may be best per-

formed at different points in the procedure. Therefore, the procedures given for these connections should be taken as a list of necessary steps and a suggested order, and modified as appropriate for your particular circumstances. CAUTION:

If the Indoor Unit has already been installed and connected as described in Chapter 5, be sure that power is disconnected from the Indoor Unit before attaching the cables from the Outdoor Unit. Signal Connection The radio signal cable should be outdoor-rated 75-ohm coaxial cable with a maximum length of 165 feet (50 m). The cable terminates with a male F connector at each end. To install the radio signal cable, perform the following steps 1. Obtain an appropriate length of cable, and run it from the Indoor Unit to the Outdoor Unit. Include a service/drip loop as appropriate. Install a male F connector at the radio/antenna end of the cable. 2. 3. Attach the cable to the female F connector on the Outdoor Unit, as shown in Figure 4-3. Tighten the connector until the cable is firmly secured, but do not overtighten. 4. Dress the outdoor portion of the cable as appropriate. 070-20000330-01 Rev A 43 CHAPTER 4. OUTDOOR UNIT INSTALLATION To Indoor Units Radio RF connector To Indoor Units Radio Control connector Figure 4-2 Connections to the Outdoor Unit (Radio/Antenna) Control Connection The control cable should be outdoor-rated Cat 5, terminating with an RJ45 male connector (plug) at each end.

Plug the cable into the RJ45 socket on the Outdoor Unit. 5. Put the rubber boot in position to protect the R-J45 connection and secure it in place with a cable tie, as shown in Figure 4-3. 6. Dress the outdoor portion of the cable as appropriate. 7. Seal the entry of both cables to the building as appropriate. 070-20000330-01 Rev A 44 5 INDOOR UNIT INSTALLATION In most cases, the installation of the Outdoor Unit should be performed before the installation of the Indoor Unit (see Chapter 5). Since the Outdoor Unit must be con-

nected to the Indoor Unit to align the antenna, the Indoor Unit should be temporarily placed close to the Outdoor Unit to facilitate this process. When the installation of the Outdoor Unit is complete, the Indoor Unit can be moved to its permanent location. INSTALLATION REQUIREMENTS You will not need any tools to install the Indoor Unit. Cable and power connections are made to the Indoor Units rear panel, illustrated in Figure 5-1. The subscriber must have either an Ethernet LAN or a computer with an Ethernet interface. You will need to supply an Ethernet cable of sufficient length, with an RJ45 plug on each end. Use a straight cable for connection to a hub or router, or a crossover cable for connection to a PC. 070-20000330-01 Rev A 51 CHAPTER 5. INDOOR UNIT INSTALLATION Figure 5-1 Indoor Unit Rear Panel 070-20000330-01 Rev A 52 CHAPTER 5. INDOOR UNIT INSTALLATION INSTALLATION PROCEDURE Installation of the Indoor Unit involves placing the unit in the desired location, con-

necting radio/antenna and local Ethernet cables to the rear panel, and applying power. Position the Indoor Unit as desired. WARNING:

070-20000330-01 Rev A 54 CHAPTER 5. INDOOR UNIT INSTALLATION Powering Up the Indoor Unit To apply power to the Indoor Unit:

1. Plug the power cord into the POWER connector on the Indoor Unit, as illus-

trated in Figure 5-5. 2. Plug the power cord/transformer into a grounded wall outlet. The Indoor Unit does not have an on/off switch; to turn the unit off, disconnect power at either the rear panel or the wall socket. The Outdoor Unit receives power from the Indoor Unit (or a separate power source) via the coaxial radio signal cable. To wall outlet Figure 5-4 Indoor Unit Power Connection 070-20000330-01 Rev A 55 CHAPTER 5. INDOOR UNIT INSTALLATION 070-20000330-01 Rev A 56 6 STARTING UP Once you have completed the connections described in Chapters 4 and 5, there is one procedure you need to complete before the local computers can access the Packet-

Wave network and the Internet. That procedure involves using the CPE Installation Tool software to optimize antenna pointing. When the Indoor Unit is first installed, its software knows that the antenna-point-

ing procedure has not been performed. It will not allow itself to access the PacketWave network until the procedure has been performed. Once the antenna-pointing procedure has been executed, it should not be required again. RUNNING THE CPE INSTALLATION (ANTENNA ALIGNMENT) TOOL See the accompanying addendum for antenna alignment instructions. 070-20000330-01 Rev A 61 CHAPTER 6. STARTING UP CONNECTION TO THE PACKETWAVE NETWORK When the Indoor Unit reboots at the end of the installation/antenna alignment process described above, it performs an initialization procedure that brings it up as part of the PacketWave network. During this procedure:

The Indoor Unit requests an IP address from the systems DHCP server. (The DHCP request is passed along by the BSUs DHCP relay agent.) The DHCP server responds with the IP address and other information, includ-

ing the name of the Indoor Units configuration file. The Base Station Unit and the Indoor Unit both learn the new IP address. The Indoor Unit downloads its configuration file (as previously created using the WaveCenter Configuration Manager) from the TFTP server. Note: For information about the WaveCenter Configuration Manager software, see the PacketWave 1000 Base Station Unit Installa-

tion, Configuration, and Operation manual. The Indoor Unit configures itself according to the received configuration file and activates for subscriber traffic. If the Indoor Unit is functioning in NAT mode, the IP addresses of its attached computers are obtained from the local DHCP server built into the Indoor Unit. Setting Up the Local Computer(s) Whether the subscribers computers are connected to a Indoor Unit functioning in bridge or NAT mode, each host needs an IP address. The simplest solution is to con-

figure each computer to obtain its IP address using DHCP. It is also possible to man-

ually enter the IP addresses. For larger subscriber LANs, a local DHCP server may be preferable. 070-20000330-01 Rev A 62 7 MANAGEMENT INTERFACES The PacketWave 130 Indoor Unit includes several management interfaces which allow the installer and user to monitor the wireless and LAN connections, diagnose problems, and perform some local configuration changes. These interfaces include:

Front-panel LEDs. A Web-browser-accessed graphical user interface (GUI) for real-time monitor-

ing and limited on-the-fly configuration changes. SNMP. A simple command line interface (CLI) for basic troubleshooting and debugging. This chapter provides information about all of these interfaces. FRONT-PANEL LEDS The LEDs on the Indoor Units front panel provide operational information as described in Table 7-A.
