capacity 2.4 GHz connections between local- and wide-area networks via broadband radio links. The NCL1135 uses direct-sequence spread spectrum (DSSS) techniques to provide secure communications and is completely network configurable. Figure 1 shows an NCL1135 point-to-point network and point-to-multipoint network. Figure 1 NCL1135 Network Examples Network Point-to-Point Network:

(Station) Ethernet APCDNC0032.0A 1 1 NCL1135 Overview The NCL1135 is used to extend Ethernet networks, access the Internet at high speed, connect remote locations, and perform general data networking without the ongoing costs of leased telephone or data lines. 1.2 Features Flexible deploymentWaveRiders NCL1135 can operate as either a bridge or router. In routing mode, the NCL1135 can be set up to use dynamic communications strategies such as the Routing Information Protocol (RIP), Dynamic Host Control Protocol (DHCP), and Open Shortest Path First (OSPF). Ethernet compatibilityWaveRiders NCL1135 allows users to connect with most Ethernet networks or devices. Microprocessor-controlled signal processingAll functions of WaveRiders spread-spectrum transceiver are controlled through the integration of a powerful microprocessor. Architectural flexibilityWaveRiders NCL1135 can be set up as a separate point-

to-point links, or in a mulitipoint configuration in which a single NCL1135 operating in master mode can deliver data to and receive data from a maximum of 20 NCL1135 devices operating in station mode. User-configurable and -customizable monitoringWaveRiders NCL1135 operating system supports Simple Network Management Protocol (SNMP), which allows for continual status monitoring of any NCL1135 in your network, and remote upgrading. Low interferenceWaveRiders implementation of Direct Sequence Spread-

Spectrum (DSSS) technology transmits signal information over a wide channel bandwidth, which reduces the potential for interference with neighboring communications systems. WaveRiders NCL1135 design permits three master units to operate in close proximity without interfering with each other. For example, three master units supporting 20 station units apiece can operate in close proximity, thus providing 60 end-user links. Software-enabled feature setsWaveRider offers NCL1135 users an easy, customizable upgrade path through software-enabled feature optioning. 2 APCDNC0032.0A

1.3 About Spread-Spectrum Radio Technology 1 NCL1135 Overview Spread-spectrum communications systems differ from conventional narrowband communications systems because they use a much larger transmission bandwidth to send the same amount of information. There are two primary forms of spread spectrumdirect sequence and frequency hopping. The NCL1135 uses direct-sequence spread-spectrum (DSSS). In DSSS systems, the transmitted information, along with a digital spreading sequence, are used to modulate the transmit carrier. The received signal is de-spread using the same digital spreading sequence, and the information recovered. Although spread spectrum appears complex and uses a wider bandwidth, DSSS offers the following advantages for its use:

Reduced power spectral densitySpreading over a wider bandwidth reduces the spectral density (power per Hz of bandwidth) of the transmitted signal, allowing simultaneous operation of many spread spectrum systems in the same frequency band and geographic area. The reduced spectral density also allows you meet the regulatory emissions requirements in frequency bands such as the ISM band. Transmission securityIt is technologically more difficult to surreptitiously recover

configuration mode: bridging or routing planning 2.1 Network Configuration The NCL1135 can be deployed in three different network configurations:

point-to-point repeater point-to-multipoint Before deploying the system, you must determine the required network topology. APCDNC0032.0A 5

2 Network Considerations 2.1.1 Point-to-Point In a typical point-to-point application, shown in Figure 2, unit A communicates directly with unit B. You can implement the link in either bridging or routing mode. Figure 2 Point-to-Point Application Ethernet Radio Ethernet NCL1135 A NCL1135 B 2.1.2 Repeater You can set up a repeater by using two NCL1135 units back-to-back. In the configuration shown in Figure 3, unit A communicates with unit B via the back-to-back NCL1135 repeater configuration of units C and D. You must use different frequencies for each leg of the path. Use this configuration to circumvent large obstacles in the radio link path, or when the link from unit A to unit B is too long to provide reasonable signal levels and data throughput. Figure 3 Repeater Application Ethernet Radio Ethernet Radio Ethernet NCL1135 A NCL1135 NCL1135 C D NCL1135 B In this configuration, the effective data throughput from unit A to unit B is the same as the lessor data throughput from unit A to unit C or unit D to unit B. That is, the throughput through a series of links will be that of the slowest link. You can implement this configuration in either bridging or routing mode. 6 APCDNC0032.0A 2 Network Considerations 2.1.3 Point-to-Multipoint Figure 4 shows an example point-to-multipoint configuration. The master, unit A, sends and receives messages to and from NCL1135 stations. In this configuration, the throughput of unit A is shared among the stations. Although stations may receive communications from other stations, because of RF propagation conditions, the stations are programmed to accept messages only from their designated master.

You can use a name based on its location, its purpose, or a combination of both. For example, a system name, Station_firehall identifies the NCL1135 configured as a Station and located at the firehall. The session to change the system name from NCL1135 to Station_firehall would look like this:

NCL1135> system name Station_firehall System name changed to: Station_firehall Station_firehall>

2. Type <write> or <save> to save the settings to memory. NOTE: In this User Manual, the command-line prompt will always be shown as NCL1135>. 3.1.3 Resetting an NCL1135 to Factory Settings If the NCL1135 is a factory-configured unit, the following procedure does not need to be performed. Use this procedure if the NCL1135 had been previously configured for use elsewhere in your network and you would like to prepare it for another location and use. 1. Connect the NCL1135 to a terminal or terminal-emulation software and at the NCL1135> prompt, type <write erase> to reset the unit to its factory-default settings. 2. Type <reboot> for the unit to recognize the factory-default settings. APCDNC0032.0A 15 3 Configuring the NCL1135 3.2 Configuring the NCL1135 The procedures to configure the NCL1135 using a command-line interface are divided into two main sections:

Radio configuration see Setting the Radio Configuration on page 16 IP configuration see Setting the IP Configuration on page 18 You can also configure the NCL1135 with the following options:

Routing Information Protocol (RIP)see Setting RIP Configuration on page 19 Open Shortest Path First (OSPF)see Setting OSPF Configuration on page 20 Dynamic Host Control Protocol (DHCP) Relaysee Setting the DHCP Relay Configuration on page 21 Simple Network Management Protocol (SNMP)see Setting the SNMP Configuration on page 22 Domain Name Server (DNS) Resolversee Setting the DNS Resolver Configuration on page 23 3.2.1 Setting the Radio Configuration Before setting the radio configuration parameters, ensure that the NCL1135 has been connected to a terminal and initialized as described in Connecting and Initializing the NCL1135, on page 12 and you have changed the password as described in Changing the NCL1135 Password, on page 14. WARNING!

3 Configuring the NCL1135 5. Set the NCL1135 as a Master or Station. To set the NCL1135 as a Master, type

<radio type master>. To set the NCL1135 as a Station, type <radio type station>. 6. If the NCL1135 is a Master, add the unit IDs for the Stations that are configured for this network group. At the NCL1135> prompt, type <radio station add station_unitid> where station_unitid is the unit ID for a Station. NOTE: To remove a Station from the Remote Station List, type <radio station del station_unitid> where station_unitid is the unit ID for the Station you want removed. 7. Repeat step 6 for each Station that you want to add to the Remote Station List for the Master NCL1135. A maximum of 20 Stations can be added to one Master. 8. If the NCL1135 is a Station, add the Master unit ID for the network group. At the NCL1135> prompt, type <radio masterID master_unitid> where master_unitid is the unit ID for Master NCL1135 in the network group. 9. At the NCL1135> prompt, type <write> to save the settings to memory. TIP: To display a list of Stations associated with a Master NCL1135, type <radio station> at the NCL1135>

prompt. APCDNC0032.0A 17 3 Configuring the NCL1135 3.2.2 Setting the IP Configuration Ensure that the NCL1135 has been connected to a terminal and initialized as described in Connecting and Initializing the NCL1135, on page 12 and you have changed the password as described in Changing the NCL1135 Password, on page 14. Complete the radio configuration as described in Setting the IP Configuration, on page 18 before configuring the IP configuration options. 1. At the NCL1135> prompt, type <ip address ethernet aaa.bbb.ccc.ddd nn>

to set the IP address for the Ethernet interface. aaa.bbb.ccc.ddd is the IP address of the NCL1135 and nn is the number of bits in the subnet mask (for example, 24 represents a subnet mask of 255.255.255.0). 2. At the NCL1135> prompt, type <mode bridging> or <mode routing> to set the forwarding mode. 3. If the mode is set to bridging in Step 2, omit this step. If the mode is routing, type <ip address radio remote_unit_id aaa.bbb.ccc.ddd eee.fff.ggg.hhh> to set the IP address for the radio interface to the remote unit. aaa.bbb.ccc.ddd is the IP address for the local unit and eee.fff.ggg.hhh is the IP address for the remote unit. NOTE: If you change the radio IP address for a Station at a later time, remember to update the Master with the new Station IP address. If you change the radio IP address for a Master at a later time, remember to update each Station in the Remote Station List with the new remote IP address for the Master. 4. For a Master unit, repeat step 3 for every Station in the group. For a Station unit, you only need to enter the remote unit IP address for the Master. 5. You can optionally add a maximum of 256 static routes for the NCL1135. At the NCL1135> prompt, type <ip route add aaa.bbb.ccc.ddd eee.fff.ggg.hhh subnet_mask> where aaa.bbb.ccc.ddd is the IP address for the destination network, eee.fff.ggg.hhh is the IP address for the gateway, and subnet_mask is specified in the number of bits. 6. If the mode is routing and the NCL1135 is a Master, type <ip route add station_ethernet_subnet station_radio_ip_address subnet_mask> to route the Master subnet traffic to the Master. 7. If the mode is routing and the NCL1135 is a Station, type <ip route add 0.0.0.0 master_radio_ip_address 0> to add a default static route to route all unknown subnets through the Master. 8. At the NCL1135> prompt, type <radio enable> to enable the NCL1135 to transmit messages. Ensure that the NCL1135 antenna port is terminated. 9. At the NCL1135> prompt, type <write> to save the settings to memory. 10. When done configuring the NCL1135, disconnect the terminal from the NCL1135. 18 APCDNC0032.0A 3 Configuring the NCL1135 3.2.3 Configuration Options The NCL1135 provides users with the following configuration options:

in Routing Mode Routing Information Protocol (RIP)see Setting RIP Configuration on page 19 Open Shortest Path First (OSPF)see Setting OSPF Configuration on page 20 Dynamic Host Control Protocol (DHCP) Relaysee Setting the DHCP Relay Configuration on page 21 for System Monitoring Simple Network Management Protocol (SNMP)see Setting the SNMP Configuration on page 22 Domain Name Server (DNS) Resolversee Setting the DNS Resolver Configuration on page 23 After completing these procedures, it is important to confirm that the configuration is correct before deploying the NCL1135 in the field. Refer to Chapter 4, Testing, on page 35. Two example configuration diagrams and sessions are provided in Examples of Bridging and Routing Configurations, on page 24: one for a point-to-multipoint bridging, and the second for a point-to multipoint routing network. Setting RIP Configuration When the NCL1135 is in Routing Mode, you can optionally enable the Routing Information Protocol (RIP) features. RIP is a protocol that runs between two routers (for example, two NCL1135s) or a route server in order toexchange information about routes. When RIP is active, RIP can be configured to advertise default routes or static routes. The NCL1135 supports both RIP version 1 and 2. RIP version 2 can be set as broadcast, compatible, or multicast. 1. At the NCL1135> prompt, type <ip routing rip> to enable RIP as the routing mode. 2. To transmit the route information in packets, type <ip rip active>. If RIP is set to quiet, it receives and processes RIP packets, but it does not transmit them. 3. Type <ip rip version> to display the current version of RIP. 4. If RIP is version 1, it is broadcast only. To change RIP routing to support version 2, type <ip rip version 2>. 5. If you set RIP to version 2, you can additionally specify how RIP handles packets. To do this.... Type... Send version 2 advertisements as broadcast.

APCDNC0032.0A 19

3 Configuring the NCL1135 To do this.... Type... Send more compatible version 1 broadcasts (intended for version 1 routers).

Disable RIP routing. Enable RIP routing. Send version 2 advertisements to RIP version 2 multicast addresses. This is generally more efficient than broadcast.

6. To enable RIP to advertise the default route, if one exists, in the advertisement, type

<ip rip default>. To send RIP to advertise static routes, as well as all other RIP information, type

<ip rip update>. noupdate sends all route information except static route information. Setting OSPF Configuration The Open Shortest Path First (OSPF) routing protocol generates an IP network layer database and forwards that information to all other routers within the same network to determine the shortest path between nodes. OSPF is compatible with other routing protocols and does not affect packet content. OSPF routing decisions are based on a Link-State Algorithmn (or Advertisement), which allows faster delivery of packetized data, particularily within larger corporate and institutional intranetworks, because each router is aware of the set of links used by every other router, rather than only those of its adjacent router. In an OSPF-enabled environment, whenever a router becomes aware of another router on one of its attached subnetworks, it creates a logical link to that system, and treats it as a neighbour. To do this.... Type... Display OSPF area configuration

Add an OSPF area Delete an OSPF area Disable OSPF protocol. Enable OSPF protocol. Configure interface parameters.

<Area.aaa.bbb.ccc.ddd>

20 APCDNC0032.0A 3 Configuring the NCL1135 Setting the DHCP Relay Configuration When the NCL1135 is in Routing mode, you can optionally enable Dynamic Host Control Protocol (DHCP) Relay which makes the NCL1135 aware of the protocol for DHCP traffic and forward the responses back to the designated DHCP Server. NOTE: DHCP Relay is transparent when the NCL1135 is in bridging mode and, therefore, is not available in that mode. You can configure a maximum of five DHCP servers in the NCL1135 configuration. 1. At the NCL1135> prompt, type <dhcp mode relay> to enable DHCP Relay in the device. 2. To add a DHCP server, type <dhcp relay add ip_address> where ip_address is the IP Address for the DHCP Server available for the NCL1135 to forward and receive DHCP traffic. 3. At the NCL1135> prompt, type <write> to save the settings to memory. NOTE: To remove a DHCP server, type <dhcp relay delete ip_address>. To disable DHCP Relay, type <dhcp mode none>. APCDNC0032.0A 21 3 Configuring the NCL1135 Setting the SNMP Configuration SNMP enables a network management station to monitor, control, and remotely configure network devices called agents. SNMP allows you to look at SNMP variables using READ communities, and to set SNMP variables using WRITE communities. Communities are optional on the NCL1135, but it can support a maximum of five communities. An NCL1135 comes factory-configured with two communities, a READ community called public and a WRITE community called private. SNMP also provides a mechanism called trap, which notifies a network management station that a significant event took place. A significant event can be an interface going down or coming up, a unit performing a cold or warm start, or an authentication failure. Refer to RFC 1157 for details. Associated with SNMP are Management Information Bases (MIBs). These specify a collection of management information available from the agent. This information can be controlled and monitored from a network management station. The NCL1135 implements SNMPv2c and includes a number of standard SNMP MIBs:

RFC1157 (MIB-Il) RFC1493 (bridging) an NCL1135-specific MIB WaveRider MIBs can be downloaded from the technical support page at www.waverider.com. The following procedure describes how to configure standard SNMP communities for read/

write access to the NCL1135 SNMP agent and to specify a server IP address to which trap messages are sent. 1. At the NCL1135> prompt, type <snmp> to display the current SNMP settings for the NCL1135. 2. To add a new community, type <snmp community add community READ|WRITE> where community is the name of the community and READ|WRITE is the community type. You can have a maximum of five communities. 3. If a community is not set up the way you want it, delete it by typing

3 Configuring the NCL1135 Setting the DNS Resolver Configuration The NCL1135 implements DNS resolver software. Once you configure the NCL1135, you can use host names instead of IP addresses when you make a Telnet connection from the NCL1135 console to other IP hosts on the network, or when you send ping messages to test connectivity. Adding DNS server lists is optional on the NCL1135, but you can configure the NCL1135 to use a maximum of five DNS servers. An NCL1135 comes factory-configured with no DNS servers in the list. You can also configure the NCL1135 with a domain name for your local IP network. The following procedure describes how to configure the NCL1135 to implement DNS resolver software and configure the NCL1135 domain name. Setting the DNS resolver configuration is optional. 1. At the NCL1135> prompt, type <ip dns> to display the current DNS setup used by the NCL1135. 2. To add a DNS Server, type <ip dns server add aaa.bbb.ccc.ddd> where aaa.bbb.ccc.ddd is the IP address of the DNS Server. 3. To delete a DNS Server, type <ip dns server del aaa.bbb.ccc.ddd> where aaa.bbb.ccc.ddd is the IP address of the DNS Server. 4. To set the domain name for your local IP network, type <ip dns domain domain_name> where domain_name is the name for your local IP network. 5. At the NCL1135> prompt, type <write> to save the settings to memory. APCDNC0032.0A 23 3 Configuring the NCL1135 3.3 Examples of Bridging and Routing Configurations The following two examples for a point-to-multipoint network configuration provide detailed diagrams for a bridging and routing configuration and the corresponding command-line sessions to configure the appropriate devices in the network. In a point-to-multipoint network configuration, all the NCL1135s in the network must be either configured as bridges or routers, not a mix of both operational modes. 3.3.1 Point-to-Multipoint Bridging Network Figure 10 shows a configuration of a typical point-to-multipoint bridging network.

You receive replies only if the link is operational. Refer to Chapter 7, Troubleshooting, on page 53 if the device does not respond. 36 APCDNC0032.0A 5 Deploying the NCL1135 The following section describes tests that you can use to optimize the signal strength and align the NCL1135 antennas after they are set up and transmitting. NOTE: You cannot run more than one test at a time at a given unit. 5.1 Optimizing Signal Strength 5.1.1 Running the Continuous Transmit (Tx) Test This test should only be used when setting up a Master and the first Station of a new network. The purpose of this test is to send a continuous stream of messages from an NCL1135 Master to a Station which receives and discards the messages, or to a spectrum analyzer for signal monitoring. The Radio Packet Error Rate (PER) is displayed at a Station receiving the Continuous Transmit messages and using that information, an installer aligns the antenna accordingly. Refer to Displaying the Radio Packet Error Rate (PER), on page 43 for more information. You will need one NCL1135 configured as a Master. At the other end of the link, you can have an NCL1135 Station or a spectrum analyzer. The following procedure describes the test for a Master NCL1135 and one Station NCL1135. If you are using a spectrum analyzer, adjust the antenna for maximum received signal. CAUTION: Do NOT run this test in a working network. Doing so will cause every device in the network to slow down. APCDNC0032.0A 37 5 Deploying the NCL1135 1. Ensure that the NCL1135s (one Master and one Station) have been configured and tested. 2. Deploy the Master and Station connecting the antennas as required. WARNING!

prompt when the test is running. 5. At the Station NCL1135 console terminal, type <radio per continuous> to begin displaying the Radio PER. Refer to Displaying the Radio Packet Error Rate (PER), on page 43 for more information. 6. Using the information from Radio PER, align the antenna at the NCL1135 Station so that the number of packets missed is at a minimum rate. 7. When done with the antenna alignment, stop the test at the Master NCL1135. Type

<radio txTest stop>. 8. At the Station NCL1135, press any key to end the Radio PER output. NOTE: By default, a Master NCL1135 keeps track of the Radio PER of each Station. A Station does not track the Radio PER of another visible Station unless it is running the Continuous Receive test. Refer to Running the Continuous Receive (Rx) Test, on page 39. A Station does track the Radio PER of both direct and broadcast communication with the Master. The information received from Radio PER during the Continuous Transmit test will be similar to the following output. The following output is from a Station (unit ID 2) communicating with the Master (unit ID 1) that is running the Continuous Transmit test. station> radio per continuous Unit Id Link Status Total # Received Total # Missed PER (%)

5.1.2 Running the Continuous Receive (Rx) Test The purpose of this test is to help you deploy an additional Station in an existing network without interrupting traffic to the currently active Stations in the network. The test is run from the new Station to sniff packets destined to every other Station (originated by the Master) in the system. The test is run simultaneously with Radio PER which displays the number of packets received and missed for each Station that is sniffed. This test can also be used at existing Stations to analyze throughput in a running system. 1. Ensure that the new Station NCL1135 has been configured and tested. 2. Deploy the Station and connect the antenna. WARNING!

Antennas and associated transmission cable must be installed by qualified personnel. Failure to terminate the antenna port correctly can permanently damage the NCL1135. WaveRider assumes no liability for failure to adhere to this recommendation or to recognized general safety precautions. 3. Connect a terminal at the Station NCL1135 using a serial cable and log into the device. 4. At the Station NCL1135, type <radio rxTest start> to begin sniffing the transmissions and automatically start the Radio PER display. Continuous Rx test started is displayed when the test is started. NOTE: If you stop the Radio PER display (press any key), you can restart the display by typing <radio per continuous>. Refer to Displaying the Radio Packet Error Rate (PER), on page 43 for more information. APCDNC0032.0A 39 5 Deploying the NCL1135 5. Using the information from Radio PER, align the antenna at the NCL1135 Station so that the number of packets missed is at a minimum rate. 6. When done with the antenna alignment, press any key to stop the Radio PER display, then type <radio rxTest stop> to stop the test. NOTE: When the Continuous Receive test is stopped, the Master NCL1135 statistics, both direct and broadcast, remain in the Radio PER list and continue to be updated. If the Continuous Receive test is restarted, the statistics for the Master and broadcast will continue from where they left off. The Stations will start from zero again. The information received from Radio PER during the Continuous Receive test will be similar to the following output. The following output is from a Station (unit ID 2) communicating with the Master (unit ID 1) that is also transmitting to another Station (unit ID 3). station> radio rxtest start Continuous Rx test started Unit Id Link Status Total # Received Total # Missed PER (%)

40 APCDNC0032.0A 5 Deploying the NCL1135 5.1.3 Performing the Transmit/Receive Loopback Test This test should only be used when setting up a new network. The purpose of this test is to ensure that the Master NCL1135 can see the Station. It also determines the quality of the links between Master and Station. The test originates at the Master NCL1135, repeatedly sending test packets to the Stations. A Station recognizes these as test packets from the Master and echoes them back to the Master. When the Master receives the replies from the Station, it updates its Radio PER for that Station. One Master NCL1135 can have up to ten Stations simultaneously echoing test packets back to it. You will need one NCL1135 configured as a Master and at least one NCL1135 Station. CAUTION: Do NOT run this test in a working network. Doing so will cause every device in the network to slow down. 1. Ensure that the Master NCL1135 and Station NCL1135s have been configured and tested. 2. Deploy the Master and at least one Station connecting the antennas for each device as required. WARNING!

Rx test started is displayed when the test is started. Refer to Displaying the Radio Packet Error Rate (PER), on page 43 for more information. 5.

APCDNC0032.0A 45 6 Operational Statistics 6.2 Displaying the Operational Statistics 6.2.1 Interface Statistics The interface statistics command displays the configuration information and statistics for the three interfaces associated with the NCL1135: radio, Ethernet and loopback. The loopback interface is an interface on a logical network that returns all output packets as input packets. The address for this logical network is 127.0.0.0 and the address for the loopback interface is usually 127.0.0.1. This means that any packets sent to the IP address 127.0.0.1 will be turned around and queued as input packets to the same interface. The values of the input and output statistics for the loopback interface should both be the same. To see the interface information for a NCL1135, type <interface statistics> at the NCL1135> prompt.

Bridge Channel A device that connects and passes packets between two network segments. Bridgers operate at the MAC layer. A bridge filters or forwards an incoming frame based on the MAC address of the frame. A learning bridge listens to traffic on its interfaces and maintains a table of addresses. See also Router. Generally, the medium through which information is communicated. In wireless communications, the channel is usually defined by the center frequency, modulation type, and occupied bandwidth. Command Line Interface

(CLI) In contrast to a graphical user interface, a CLI is a configuration and control interface based on keyboard-entry commands and responses. Console Port Typically, the 9-pin RS 232 serial port on an NCL1135 to which a terminal or laptop computer is connected to configure or control the device. Domain Name Server

(DNS) A database system that translates IP addresses into domain names. For example, 207.23.187.242 is converted into waverider.com. Direct-Sequence Spread Spectrum (DSSS) A form of spread-spectrum communications that uses a high-

speed code sequence, along with the information being sent, to modulate the RF carrier. MAC address Master Master ID This refers to the 6-byte low-level hardware address of physical address of an Ethernet device. The NCL1135 defined as a master provides the access control for all NCL1135 stations in the same radio network. The master configuration determines the channel that the NCL1135 stations use. There must be only one master using the same channel in the radio network. You must configure a master within the coverage area of another master to use a different channel. Improves security on the wireless network. NCL1135s must have the same master ID in order to communicate with each other. 70 APCDNC0032.0A Term Master vs. Station Open Shortest Path First Radio Channel Radio Type Router Routing Information Protocol Static Route Station System Name System Password Unit ID Definition Decide which NCL1135 is the master. In the point-to-point configurations, it does not matter which NCL1135 is master, just remember that the master provides the access control to the station. In the case of point-to-multipoint, the master must have a line of sight to each station, but each station may not have a radio communication path to other stations. A routing protocol for autonomous IP networks based on the Shortest Path First (SPF) algorithm, where link-state advertisements (LSAs) are sent to all other routers within the same network to determine the shortest path to the desired node. A 22 MHz wide RF channel with a center frequency specified in Appendix C. In any given network, all NCL1135s must operate on the same radio channel to communicate. This parameter specifies the role of the NCL1135 in the radio network. Each NCL1135 is classified as either a master or a station. A device that connects and passes packets between two or more network segments. A router filters or forwards an incoming packet based on the IP address of the packet. Routers use static routes which take precedence over routes chosen by all dynamic routing protocols. See also Bridge. A routing protocol for IP networks based on the distance-

vector algorithm, where all or a portion of the routing table is sent to all other neighbouring devices along with each message. A route that is explicitly configured and entered in the routing table. Static routes take precedence over routes chosen by dynamic routing protocols. An NCL1135 defined as a station synchronizes with an NCL1135 master that has the same station and master ID setting. A name that allows a user to identify a particular NCL1135. Once the Name is assigned, the system name appears as the prompt. A set of characters that prevents unauthorized access to console commands. The same password applies when accessing the console from the RS-232 port, from the network using Telnet, or when connecting to the FTP server. In the case of a station, unit ID provides the wireless address at the station. In the case of a Master, a list of unit IDs forms the access list of stations allowed to communicate with the Master. Any station not on the list will be disabled whenever the station attempts to access the Master.

Software License Agreement on page ii Warranty on page iv Regulatory Notices on page x Warnings and Advisories on page xii This NCL1135 User Manual provides you with information necessary for planning, installing, and operating an NCL1135-based system. The information has been organized in the following sections:

spectrum system must correct the interference problem, even if such correction requires the Part 15 transmitter to cease operation. The FCC does not exempt spread-spectrum devices from this latter requirement regardless of the application. The FCC strongly recommends that utilities, cellular stations, public safety services, government agencies, and others that provide critical communication services exercise due caution to determine if there are any nearby radio services that can be affected by their communications. x APCDNC0031.0 Operational Requirements In accordance with the FCC Part 15 regulations:

multipoint systems, omni-directional applications, and multiple co-located intentional radiators transmitting the same information. The operator of the spread-spectrum intentional radiator or, if the equipment is professionally installed, the installer is responsible for ensuring that the system is used exclusively for fixed, point-to-point operations. 5. The operator of a spread-spectrum system is responsible for ensuring that the system is operated in the manner outlined in Interference Environment on page x and Operational Requirements on page xi. APCDNC0031.0 xi Warnings and Advisories General Advisory Operator and maintenance personnel must be familiar with the related safety requirements before they attempt to install or operate the NCL1135 equipment. It is the responsibility of the operator to ensure that the public is not exposed to excessive Radio Frequency (RF) levels. The applicable regulations can be obtained from local authorities. WARNING!

Do not operate the NCL1135 without connecting a 50-ohm termination to the antenna port. This termination can be a 50-ohm antenna or a 50-ohm resistive load capable of absorbing the full RF output power of the transceiver. Failure to terminate the antenna port properly may cause permanent damage to the NCL1135. xii APCDNC0031.0 Customer Support If you have any problems with the hardware or software, please contact WaveRider Communications Inc.

capacity wireless 2.4 GHz connections between local- and wide-area networks. The NCL1135 uses direct-sequence spread spectrum (DSSS) techniques to provide secure communications and is completely network configurable. Figure 1 shows an NCL1135 point-to-point network and point-to-multipoint network. Figure 1 NCL1135 Network Examples Network Point-to-Point Network:

(Station) Ethernet APCDNC0031.0 1 Chapter 1 NCL1135 Overview The NCL1135 is used to extend Ethernet networks, access the Internet at high speed, connect remote locations, and perform general data networking without the ongoing costs of leased telephone or data lines. The NCL1135 provides an Ethernet interface that allows you to connect to most Ethernet networks or devices. One NCL1135 modulates and transmits data to remote NCL1135s, which demodulate, decode, and pass the data to the receiving user network. DSSS signal processing exploits the ability of transceivers to spread the signal information over a wide channel bandwidth. This reduces the potential for interference with neighboring communications systems. Because the NCL1135 operates in the microwave frequency range, a line-of-sight communication link is required, therefore, some installations have the antenna on rooftops or communications towers. The NCL1135 is user-configurable and can be remotely upgraded. The NCL1135 operating system supports simple network management protocol (SNMP) which allows for constant status monitoring of any NCL1135 in your network. All aspects of WaveRiders spread-spectrum transceiver are controlled through the integration of a powerful microprocessor. The 2.4 GHz radio transceiver allows a single NCL1135 operating in master mode to deliver data to and receive data from a maximum of 20 NCL1135 devices operating in station mode. The NCL1135 design permits three master units to operate in close proximity without interfering with each other. For example, three master units each supporting 20 station units can operate in close proximity, thus establishing 60 links. 2 APCDNC0031.0 1.2 Spread-Spectrum Radio Technology Chapter 1 NCL1135 Overview Spread-spectrum communications systems differ from conventional narrowband communications systems because these systems use a much larger transmission bandwidth to send the same amount of information. There are two primary forms of spread spectrumdirect sequence and frequency hopping. The NCL1135 uses direct-sequence spread-spectrum (DSSS). In DSSS systems, the transmitted information, along with a digital spreading sequence, are used to modulate the transmit carrier. The received signal is de-spread using the same digital spreading sequence, and the information recovered. Although spread spectrum appears complex and uses a wider bandwidth, DSSS offers the following advantages for its use:

Reduced power spectral density Spreading over a wider bandwidth reduces the spectral density (power per Hz of bandwidth) of the transmitted signal, allowing simultaneous operation of many spread spectrum systems in the same frequency band and geographic area. The reduced spectral density also allows you meet the regulatory emissions requirements in frequency bands such as the ISM band. Transmission security It is technologically more difficult to surreptitiously recover

(or jam, in the case of military communications systems) spread-spectrum signals than it is to recover conventional narrowband signals. Interference suppression The same mechanism that de-spreads the desired signal in the receiver, also spreads undesired signals, which then appears to the receiver as lower levels of RF noise. For more information about spread spectrum communications, contact the WaveRider Customer Support Centre. APCDNC0031.0 3 This page is intentionally left blank 2 Network Considerations This section provides an overview of the network considerations that you should make before beginning to implement an NCL1135 network. These network considerations include the following:

network topologies mode: bridging and routing network planning 2.1 Network Topology The NCL1135 can be deployed in three different configurations:

point-to-point repeater point-to-multipoint Before configuring the system, you must determine the required network topology. APCDNC0031.0 5 Chapter 2 Network Considerations 2.1.1 Point-to-Point In a typical point-to-point application, shown in Figure 2, unit A communicates directly with unit B. You can implement the link in either bridging or routing mode. Figure 2 Point-to-Point Application Ethernet Radio Ethernet NCL1135 A NCL1135 B 2.1.2 Repeater You can set up a repeater by using two NCL1135 units back-to-back. In the configuration shown in Figure 3, unit A communicates with unit B via the back-to-back NCL1135 repeater configuration of units C and D. You must use different frequencies for each leg of the path. Use this configuration to circumvent large obstacles in the radio link path, or when the link from unit A to unit B is too long to provide reasonable signal levels and data throughput. Figure 3 Repeater Application Ethernet Radio Ethernet Radio Ethernet NCL1135 A NCL1135 NCL1135 C D NCL1135 B In this configuration, the effective data throughput from unit A to unit B is the same as the lessor data throughput from unit A to unit C or unit D to unit B. That is, the throughput through a series of links will be that of the slowest link. You can implement this configuration in either bridging or routing mode. 6 APCDNC0031.0 Chapter 2 Network Considerations 2.1.3 Point-to-Multipoint Figure 4 shows an example point-to-multipoint configuration. The master, unit A, sends and receives messages to and from NCL1135 stations. In this configuration, the throughput of unit A is shared among the stations. Although stations may receive communications from other stations, because of RF propagation conditions, the stations are programmed to accept messages only from their designated master.

Figure 9 Console Port Pin-out Diagram 1 2 3 4 5 DB9 Male DTE Configuration Pin 2 Rx line Pin 3 Tx line Pin 5 Ground 6 7 8 9 3. If you are using a terminal-emulation package, such as HyperTerminal, start the application. 4. In the terminal-emulation application, select the communications port that you are using to connect to the NCL1135. 5. Configure the application using the following settings:

9600 bps 8 data bits no parity 1 stop bit no flow control 6. Plug the NCL1135 into a 110 or 220 V AC power source using the power cord provided with the unit. The NCL1135 begins an initialization sequence displaying progress messages on the terminal screen. When it completes initialization, it displays a message to indicate that the system is operational and the PASSWORD: prompt appears. 7. At the PASSWORD: prompt, press ENTER. The NCL1135 comes factory-configured with no password. 8. Change the password for the NCL1135 by following the instructions in Changing the NCL1135 Password, on page 14. 9. Change the system name in the NCL1135 as described in Setting the NCL1135 System Name, on page 15. 10. If the NCL1135 had been configured for use elsewhere in your network, reset the unit by following the instructions is Resetting an NCL1135 to Factory Settings, on page 15. If the NCL1135 is a factory-configured unit, you can omit this step. The NCL1135 is now ready to be configured for your network. APCDNC0031.0 13 Chapter 3 Configuring the NCL1135 3.1.1 Changing the NCL1135 Password You must be successfully connected and logged into the NCL1135. For security, we recommend that you set the password for each unit in your network to a unique password and that you record the password on the Configuration Data Record for the group. Refer to Appendix E for a copy of the NCL1135 Network Group Configuration Data Record. 1. At the NCL1135> prompt, type <system password>. 2. At the Enter Current Password: prompt, type the old password. 3. At the Enter New Password: prompt, type the new password. TIP: Use a maximum of sixteen (16) alphanumeric, ASCII characters. Passwords are case-sensitive. For example, abc is not the same as aBc. 4. At the Verify password: prompt, type the new password again. 5. The system will display a message that your password has been successfully changed. Your session to change the password may be similar to the following example session:

NCL1135> system password Enter Current Password: *******

Enter New Password: ****

Verify password: ****

System password has been changed. NCL1135>

6. Type <write> or <save> to save the settings to memory. CAUTION: Remember to record the password in your Data Configuration Record. Unlocking the NCL1135 can be a complicated process. If you have forgotten the password, contact the WaveRider Customer Support Centre for assistance. 14 APCDNC0031.0 Chapter 3 Configuring the NCL1135 3.1.2 Setting the NCL1135 System Name You must be successfully connected and logged into the NCL1135. 1. At the NCL1135> prompt, type <system name your_system_name> to name the NCL1135 in your system. TIP: We recommend that you use a system name that uniquely identifies the unit. You can use a name based on its location, its purpose, or a combination of both. For example, a system name, Station_firehall identifies the NCL1135 configured as a Station and located at the firehall. The session to change the system name from NCL1135 to Station_firehall would look like this:

NCL1135> system name Station_firehall System name changed to: Station_firehall Station_firehall>

NOTE: In this User Manual, the command-line prompt will always be shown as NCL1135>. 2. Type <write> or <save> to save the settings to memory. 3.1.3 Resetting an NCL1135 to Factory Settings If the NCL1135 is a factory-configured unit, the following procedure does not need to be performed. Use this procedure if the NCL1135 had been previously configured for use elsewhere in your network and you would like to prepare it for another location and use. 1. Connect the NCL1135 to a terminal or terminal-emulation software and at the NCL1135> prompt, type <write erase> to reset the unit to its factory-default settings. 2. Type <reboot> for the unit to recognize the factory-default settings. APCDNC0031.0 15 Chapter 3 Configuring the NCL1135 3.2 Configuring the NCL1135 The procedures to configure the NCL1135 using a command-line interface are broken into two main sections:

Radio configuration see Setting the Radio Configuration on page 16 IP configuration see Setting the IP Configuration on page 18 To configure an NCL1135 correctly, you must complete both the radio and IP configuration procedures. You can also configure the NCL1135 with the following functionality:

DHCP Relay see Setting the DHCP Relay Configuration on page 19 SNMP see Setting the SNMP Configuration on page 20 DNS Resolver see Setting the DNS Resolver Configuration on page 21 3.2.1 Setting the Radio Configuration Before setting the radio configuration parameters, ensure that the NCL1135 has been connected to a terminal and initialized as described in Connecting and Initializing the NCL1135, on page 12 and you have changed the password as described in Changing the NCL1135 Password, on page 14. WARNING!

<radio type master>. To set the NCL1135 as a Station, type <radio type station>. 16 APCDNC0031.0 Chapter 3 Configuring the NCL1135 6. If the NCL1135 is a Master, add the unit IDs for the Stations that are configured for this network group. At the NCL1135> prompt, type <radio station add station_unitid> where station_unitid is the unit ID for a Station. NOTE: Repeat step 6 for each Station that you want to add to the Remote Station List for the Master NCL1135. A maximum of 20 Stations can be added to one Master. NOTE: To remove a Station from the Remote Station List, type <radio station del station_unitid> where station_unitid is the unit ID for the Station you want removed. 7. If the NCL1135 is a Station, add the Master unit ID for the network group. At the NCL1135> prompt, type <radio masterID master_unitid> where master_unitid is the unit ID for Master NCL1135 in the network group. TIP: To display a list of Stations associated with a Master NCL1135, type <radio station> at the NCL1135>

prompt. 8. At the NCL1135> prompt, type <write> to save the settings to memory. APCDNC0031.0 17 Chapter 3 Configuring the NCL1135 3.2.2 Setting the IP Configuration Ensure that the NCL1135 has been connected to a terminal and initialized as described in Connecting and Initializing the NCL1135, on page 12 and you have changed the password as described in Changing the NCL1135 Password, on page 14. Complete the radio configuration as described in Setting the IP Configuration, on page 18 before configuring the IP configuration options. 1. At the NCL1135> prompt, type <ip address ethernet aaa.bbb.ccc.ddd nn>

to set the IP address for the Ethernet interface. aaa.bbb.ccc.ddd is the IP address of the NCL1135 and nn is the number of bits in the subnet mask (for example, 24 represents a subnet mask of 255.255.255.0). 2. At the NCL1135> prompt, type <mode bridging> or <mode routing> to set the forwarding mode. 3. If the mode is set to bridging in Step 2, omit this step. If the mode is routing, type <ip address radio remote_unit_id aaa.bbb.ccc.ddd eee.fff.ggg.hhh> to set the IP address for the radio interface to the remote unit. aaa.bbb.ccc.ddd is the IP address for the local unit and eee.fff.ggg.hhh is the IP address for the remote unit. NOTE: For a Master unit, repeat step 3 for every Station in the group. For a Station unit, you only need to enter this command once. NOTE: If you change the radio IP address for a Station at a later time, remember to update the Master with the new Station IP address. If you change the radio IP address for a Master at a later time, remember to update each Station in the Remote Station List with the new remote IP address for the Master. 4. You can optionally add a maximum of 256 static routes for the NCL1135. At the NCL1135> prompt, type <ip route add aaa.bbb.ccc.ddd eee.fff.ggg.hhh subnet_mask> where aaa.bbb.ccc.ddd is the IP address for the destination network, eee.fff.ggg.hhh is the IP address for the gateway, and subnet_mask is specified in the number of bits. 5. If the mode is routing and the NCL1135 is a Master, type <ip route add station_ethernet_subnet station_radio_ip_address subnet_mask> to route the Master subnet traffic to the Master. 6. If the mode is routing and the NCL1135 is a Station, type <ip route add 0.0.0.0 master_radio_ip_address 0> to add a default static route to route all unknown subnets through the Master. 7. At the NCL1135> prompt, type <radio enable> to enable the NCL1135 to transmit messages. Ensure that the NCL1135 antenna port is terminated. 8. At the NCL1135> prompt, type <write> to save the settings to memory. 9. When done configuring the NCL1135, disconnect the terminal from the NCL1135. 18 APCDNC0031.0 Chapter 3 Configuring the NCL1135 You can also optionally set the following additional configuration options in the NCL1135:

DHCP Relay see Setting the DHCP Relay Configuration on page 19 SNMP see Setting the SNMP Configuration on page 20 DNS Resolver see Setting the DNS Resolver Configuration on page 21 After the NCL1135 configuration is complete, you should test it to ensure the configuration is correct before you deploy it in the field. Refer to Chapter 4, Testing, on page 33. Two example configuration diagrams and sessions are provided in Examples of Bridging and Routing Configurations, on page 22: one for a point-to-multipoint bridging, and the second for a point-to multipoint routing network. Setting the DHCP Relay Configuration When the NCL1135 is in Routing mode, you can optionally enable Dynamic Host Control Protocol (DHCP) Relay which makes the NCL1135 aware of the protocol for DHCP traffic and forward the responses back to the designated DHCP Server. NOTE: DHCP Relay is transparent when the NCL1135 is in bridging mode and, therefore, is not available in that mode. You can configure a maximum of five DHCP servers in the NCL1135 configuration. 1. At the NCL1135> prompt, type <dhcp mode relay> to enable DHCP Relay in the device. 2. To add a DHCP server, type <dhcp relay add ip_address> where ip_address is the IP Address for the DHCP Server available for the NCL1135 to forward and receive DHCP traffic. 3. At the NCL1135> prompt, type <write> to save the settings to memory. NOTE: To remove a DHCP server, type <dhcp relay delete ip_address>. To disable DHCP Relay, type <dhcp mode none>. APCDNC0031.0 19 Chapter 3 Configuring the NCL1135 Setting the SNMP Configuration SNMP enables a network management station to monitor, control, and remotely configure network devices called agents. SNMP allows you to look at SNMP variables using READ communities, and to set SNMP variables using WRITE communities. Communities are optional on the NCL1135, but it can support a maximum of five communities. An NCL1135 comes factory-configured with two communities, a READ community called public and a WRITE community called private. SNMP also provides a mechanism called trap, which notifies a network management station that a significant event took place. A significant event can be an interface going down or coming up, a unit performing a cold or warm start, or an authentication failure. Refer to RFC 1157 for details. Associated with SNMP are Management Information Bases (MIBs). These specify a collection of management information available from the agent. This information can be controlled and monitored from a network management station. The NCL1135 implements SNMPv2c and includes a number of standard SNMP MIBs:

<snmp community del community READ|WRITE> where community is the name of the community and READ|WRITE is the community type. 4. At the NCL1135> prompt, type <snmp location location> to change the geographical location of the NCL1135. 5. Type <snmp contact contact> to change the contact name for the NCL1135. The contact can be a name and phone number, a URL, or an email address. 6. To add a trap server to the NCL1135 configuration, type <snmp trap add aaa.bbb.ccc.ddd community> where aaa.bbb.ccc.ddd is the IP address of the trap server and community is the name of the community on the trap server. 7. To delete a trap server from the NCL1135 configuration, type <snmp trap del aaa.bbb.ccc.ddd community> where aaa.bbb.ccc.ddd is the IP address of the trap server and community is the name of the community on the trap server. 8. At the NCL1135> prompt, type <write> to save the settings to memory. 20 APCDNC0031.0 Chapter 3 Configuring the NCL1135 Setting the DNS Resolver Configuration The NCL1135 implements DNS resolver software. Once you configure the NCL1135, you can use host names instead of IP addresses when you make a Telnet connection from the NCL1135 console to other IP hosts on the network, or when you send ping messages to test connectivity. Adding DNS server lists is optional on the NCL1135, but you can configure the NCL1135 to use a maximum of five DNS servers. An NCL1135 comes factory-configured with no DNS servers in the list. You can also configure the NCL1135 with a domain name for your local IP network. The following procedure describes how to configure the NCL1135 to implement DNS resolver software and configure the NCL1135 domain name. Setting the DNS resolver configuration is optional. 1. At the NCL1135> prompt, type <ip dns> to display the current DNS setup used by the NCL1135. 2. To add a DNS Server, type <ip dns server add aaa.bbb.ccc.ddd> where aaa.bbb.ccc.ddd is the IP address of the DNS Server. 3. To delete a DNS Server, type <ip dns server del aaa.bbb.ccc.ddd> where aaa.bbb.ccc.ddd is the IP address of the DNS Server. 4. To set the domain name for your local IP network, type <ip dns domain domain_name> where domain_name is the name for your local IP network. 5. At the NCL1135> prompt, type <write> to save the settings to memory. APCDNC0031.0 21 Chapter 3 Configuring the NCL1135 3.3 Examples of Bridging and Routing Configurations The following two examples for a point-to-multipoint network configuration provide detailed diagrams for a bridging and routing configuration and the corresponding command-line sessions to configure the appropriate devices in the network. In a point-to-multipoint network configuration, all the NCL1135s in the network must be either configured as bridges or routers, not a mix of both operational modes. 3.3.1 Point-to-Multipoint Bridging Network Figure 10 shows a configuration of a typical point-to-multipoint bridging network.

Refer to Chapter 7, Troubleshooting, on page 51 if the device does not respond. 34 APCDNC0031.0 5 Deploying the NCL1135 The following section describes tests that you can use to optimize the signal strength and align the NCL1135 antennas after they are set up and transmitting. NOTE: You cannot run more than one test at a time at a given unit. 5.1 Optimizing Signal Strength 5.1.1 Running the Continuous Transmit (Tx) Test This test should only be used when setting up a Master and the first Station of a new network. The purpose of this test is to send a continuous stream of messages from an NCL1135 Master to a Station which receives and discards the messages, or to a spectrum analyzer for signal monitoring. The Radio Packet Error Rate (PER) is displayed at a Station receiving the Continuous Transmit messages and using that information, an installer aligns the antenna accordingly. Refer to Displaying the Radio Packet Error Rate (PER), on page 41 for more information. You will need one NCL1135 configured as a Master. At the other end of the link, you can have an NCL1135 Station or a spectrum analyzer. The following procedure describes the test for a Master NCL1135 and one Station NCL1135. If you are using a spectrum analyzer, adjust the antenna for maximum received signal. CAUTION: Do NOT run this test in a working network. Doing so will cause every device in the network to slow down. APCDNC0031.0 35 Chapter 5 Deploying the NCL1135 1. Ensure that the NCL1135s (one Master and one Station) have been configured and tested. 2. Deploy the Master and Station connecting the antennas as required. WARNING!

Refer to Displaying the Radio Packet Error Rate (PER), on page 41 for more information. 6. Using the information from Radio PER, align the antenna at the NCL1135 Station so that the number of packets missed is at a minimum rate. 7. When done with the antenna alignment, stop the test at the Master NCL1135. Type

<radio txTest stop>. 8. At the Station NCL1135, press any key to end the Radio PER output. NOTE: By default, a Master NCL1135 keeps track of the Radio PER of each Station. A Station does not track the Radio PER of another visible Station unless it is running the Continuous Receive test. Refer to Running the Continuous Receive (Rx) Test, on page 37. A Station does track the Radio PER of both direct and broadcast communication with the Master. The information received from Radio PER during the Continuous Transmit test will be similar to the following output. The following output is from a Station (unit ID 2) communicating with the Master (unit ID 1) that is running the Continuous Transmit test. station> radio per continuous Unit Id Link Status Total # Received Total # Missed PER (%)

Antennas and associated transmission cable must be installed by qualified personnel. Failure to terminate the antenna port correctly can permanently damage the NCL1135. WaveRider assumes no liability for failure to adhere to this recommendation or to recognized general safety precautions. 3. Connect a terminal at the Station NCL1135 using a serial cable and log into the device. 4. At the Station NCL1135, type <radio rxTest start> to begin sniffing the transmissions and automatically start the Radio PER display. Continuous Rx test started is displayed when the test is started. NOTE: If you stop the Radio PER display (press any key), you can restart the display by typing <radio per continuous>. Refer to Displaying the Radio Packet Error Rate (PER), on page 41 for more information. APCDNC0031.0 37 Chapter 5 Deploying the NCL1135 5. Using the information from Radio PER, align the antenna at the NCL1135 Station so that the number of packets missed is at a minimum rate. 6. When done with the antenna alignment, press any key to stop the Radio PER display, then type <radio rxTest stop> to stop the test. NOTE: When the Continuous Receive test is stopped, the Master NCL1135 statistics, both direct and broadcast, remain in the Radio PER list and continue to be updated. If the Continuous Receive test is restarted, the statistics for the Master and broadcast will continue from where they left off. The Stations will start from zero again. The information received from Radio PER during the Continuous Receive test will be similar to the following output. The following output is from a Station (unit ID 2) communicating with the Master (unit ID 1) that is also transmitting to another Station (unit ID 3). station> radio rxtest start Continuous Rx test started Unit Id Link Status Total # Received Total # Missed PER (%)

38 APCDNC0031.0 Chapter 5 Deploying the NCL1135 5.1.3 Performing the Transmit/Receive Loopback Test This test should only be used when setting up a new network. The purpose of this test is to ensure that the Master NCL1135 can see the Station. It also determines the quality of the links between Master and Station. The test originates at the Master NCL1135, repeatedly sending test packets to the Stations. A Station recognizes these as test packets from the Master and echoes them back to the Master. When the Master receives the replies from the Station, it updates its Radio PER for that Station. One Master NCL1135 can have up to ten Stations simultaneously echoing test packets back to it. You will need one NCL1135 configured as a Master and at least one NCL1135 Station. CAUTION: Do NOT run this test in a working network. Doing so will cause every device in the network to slow down. 1. Ensure that the Master NCL1135 and Station NCL1135s have been configured and tested. 2. Deploy the Master and at least one Station connecting the antennas for each device as required. WARNING!

Rx test started is displayed when the test is started. Refer to Displaying the Radio Packet Error Rate (PER), on page 41 for more information. 5. Using the information from Radio PER, determine the quality of the link between the Master and Stations. 6. When done, press any key to stop Radio PER, then stop the Transmit/Receive Loopback Test by typing <radio txrx stop>. APCDNC0031.0 39 Chapter 5 Deploying the NCL1135 The information received from Radio PER during the Transmit/Receive Loopback test will be similar to the following output.

APCDNC0031.0 43 Chapter 6 Operational Statistics 6.2 Displaying the Operational Statistics 6.2.1 Interface Statistics The interface statistics command displays the configuration information and statistics for the three interfaces associated with the NCL1135: radio, Ethernet and loopback. The loopback interface is an interface on a logical network that returns all output packets as input packets. The address for this logical network is 127.0.0.0 and the address for the loopback interface is usually 127.0.0.1. This means that any packets sent to the IP address 127.0.0.1 will be turned around and queued as input packets to the same interface. The values of the input and output statistics for the loopback interface should both be the same. To see the interface information for a NCL1135, type <interface statistics> at the NCL1135> prompt. Table 2 provides definitions for the statistics labels. For a Master NCL1135, information similar to the following example is displayed. NCL1135> interface statistics Statistics For Loopback

Bridgers operate at the MAC layer. A bridge filters or forwards an incoming frame based on the MAC address of the frame. A learning bridge listens to traffic on its interfaces and maintains a table of addresses. See also Router. Generally, the medium through which information is communicated. In wireless communications, the channel is usually defined by the center frequency, modulation type, and occupied bandwidth. Command Line Interface

speed code sequence, along with the information being sent, to modulate the RF carrier. MAC address Master Master ID Master vs. Station This refers to the 6-byte low-level hardware address of physical address of an Ethernet device. The NCL1135 defined as a master provides the access control for all NCL1135 stations in the same radio network. The master configuration determines the channel that the NCL1135 stations use. There must be only one master using the same channel in the radio network. You must configure a master within the coverage area of another master to use a different channel. Improves security on the wireless network. NCL1135s must have the same master ID in order to communicate with each other. Decide which NCL1135 is the master. In the point-to-point configurations, it does not matter which NCL1135 is master, just remember that the master provides the access control to the station. In the case of point-to-multipoint, the master must have a line of sight to each station, but each station may not have a radio communication path to other stations. APCDNC0031.0 65 Appendix B Abbreviations and Terminology Term Radio Channel Radio Type Router Static Route Station System Name System Password Unit ID Definition A 22 MHz wide RF channel with a center frequency specified in Appendix C. In any given network, all NCL1135s must operate on the same radio channel to communicate. This parameter specifies the role of the NCL1135 in the radio network. Each NCL1135 is classified as either a master or a station. A device that connects and passes packets between two or more network segments. A router filters or forwards an incoming packet based on the IP address of the packet. Routers use static routes which take precedence over routes chosen by all dynamic routing protocols. See also Bridge. A route that is explicitly configured and entered in the routing table. Static routes take precedence over routes chosen by dynamic routing protocols. An NCL1135 defined as a station synchronizes with an NCL1135 master that has the same station and master ID setting. A name that allows a user to identify a particular NCL1135. Once the Name is assigned, the system name appears as the prompt. A set of characters that prevents unauthorized access to console commands. The same password applies when accessing the console from the RS-232 port, from the network using Telnet, or when connecting to the FTP server. In the case of a station, unit ID provides the wireless address at the station. In the case of a Master, a list of unit IDs forms the access list of stations allowed to communicate with the Master. Any station not on the list will be disabled whenever the station attempts to access the Master. 66 APCDNC0031.0 Appendix C Operating Channel Frequencies The following table defines the channel frequency set for each WaveRider regulatory domain..
