RF Energy Health Hazard The radio equipment described in this guide uses radio frequency transmitters. Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard. Do not allow people to come in close proximity to the front of the antenna while the transmitter is operating. The antenna will be professional installed on fixed-mounted outdoor permanent structures to provide separation from any other antenna and all persons as detailed on page 1-2. Protection from Lightning Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building. The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode.

MK-MAN-01 AB-Full Access Digital Radio 2 System Description 2.1 About This Manual This manual is written for those who are involved in the hands-on installation of the CarrierWave Digital Radio, such as installation technicians, site evaluators, project managers, and network engineers. It assumes the reader has a basic understanding of how to install hardware, use Windows based software, and operate test equipment. 2.2 Introduction The CarrierWave family of digital license-free radios provides high capacity transmission, flexibility, features, and convenience for wireless digital communications networks. The CarrierWave digital radios are spectrum and data rate scalable, enabling service providers or organizations to trade-off system gain with spectral efficiency and channel availability for optimal network connectivity. CarrierComms digital radio family enables service providers and enterprises to offer a portfolio of secure, scalable wireless applications for data, video, and Voice over IP (VoIP). The CarrierWave digital radio family operates in the Industrial, Scientific, and Medical (ISM) band of 5.725 to 5.850 GHz, which is typically referred generically as 5.8 GHz. The CarrierWave Digital Radio family supports two types of user data payload connectivity:

SONET/SDH wireless bridging between two fixed coordinated locations without the delay and expense of trenching fiber or the added costs of leasing dedicated OC-3 lines. 100Base-TX intelligent bridging between two locations without the delay and expense of installing cable or traditional microwave

- Scalable Ethernet capability of 25 and 50 Mbps is included. These scalable radios provide LAN connectivity and offer performance trade-offs between operational bandwidths, data rates, and distance. For customers such as cellular carriers requiring backhaul and backbone extension as well as service providers requiring network redundancy, new Points of Presence (POPs), and last mile access, the CarrierWave-155 radio is a cost effective alternative to leased lines with carrier-class quality of performance. The CarrierWave-100 radio is a cost effective solution to meet the growing demand for enterprise Local Area Network (LAN) connectivity between buildings and campuses as well as service providers requiring reliable products for infrastructure expansion, extending Metropolitan Area Network (MAN) fiber access, and network redundancy. CarrierWave Digital Radio MK-MAN-01 2-2 System Description The CarrierWave Digital Radio includes integrated Operations, Administration, Maintenance, and Provisioning (OAM&P) functionality and design features enabling simple commissioning when the radio network is initially set up in the field at the customers premises. Furthermore, a highlight of CarrierComms radio products is scalability and the capability to support a ring-type architecture. This ring or consecutive point radio architecture is self-healing in the event of an outage in the link and automatically re-routes data traffic, thereby ensuring that service to the end user is not interrupted. The overall architecture consists of a single 2RU rack mount Indoor Unit (IDU) with a cable connecting to an Outdoor Unit (ODU) with an integrated antenna. There is an option for interfacing the ODU with an external antenna (contact factory for availability). The IDU/ODU architecture is advantageous when compared to a single IDU with external mount antenna since supporting a signal of 5.8 GHz from the IDU rack to the antenna will experience significant signal degradation requiring expensive coaxial cable or waveguide. Figure 2-1. CarrierWave IDU/ODU Architecture Table 2-1 lists key features that CarrierWave technology offers to those involved in the design, deployment and support of broadband fixed wireless networks.

-48v (Isolated Input); 2-pin captive power connector. The CarrierWave Digital Radio requires an input of 37 to 60 volts dc at the rear panel DC Input connector. The total required power is a maximum of 70 W. The IDU rear panel power connector pin numbering is 1 through 2, from left to right, when facing the unit rear panel. Pin 1 is the power supply return and is connected to unit chassis ground internally. Pin 2 should be supplied with a nominal 48 V dc, with respect to the unit chassis (ground). A ground-isolated supply may be used, provided it will tolerate grounding of its most positive output. The recommended power input is 44 to 52 V dc at 2 Amps minimum. It is recommended that any power supply used be able to supply a minimum of 100 W to the IDU. is supplied with A mating power cable connector the CarrierWave IDU. It is a 2-pin plug, 5 mm pitch, manufactured by Phoenix Contact, P/N 17 86 83 1 (connector type MSTB 2,5/2-STF). This connector has screw clamp terminals that accommodate 24 AWG to 12 AWG wire. The power cable wire should be selected to provide the appropriate current with minimal voltage drop, based on the power supply voltage and length of cable required. The recommended wire size for power cables under 10 feet in length supplying 48 Vdc is 18 AWG. The IDU supplies the ODU with all required power via the ODU/IDU Interconnect cable. The CarrierWave Digital Radio IDU does not have a power on/off switch. When DC power is connected to the IDU, the digital radio powers up and is operational. There can be up to 200 mW of RF power present at the antenna port (external antenna version). The antenna should be directed safely when power is applied.

Single T1 supported on SONET IDUs Figure 2-6. CarrierWave System Block Diagram The IDU interfaces with the ODU to receive and provide modulated transmit and receive waveforms. The IDU interfaces provide SONET OC-3 (CarrierWave-155) and Fast Ethernet 100Base-T (CarrierWave-100) connections to the network. In addition, one (SONET model) or two (Ethernet model) T1 channels are provided for PBX extension. SNMP is provided on 10/100BaseT ports. The ODU RF Up/Down Converter card provides the interface to the antenna. The transmit section up converts and amplifies the modulated Intermediate Frequency (IF) of 2.375 GHz from the IF Processor and provides additional filtering. The receive section down converts the received signal, provides additional filtering, and outputs an IF of 1.675 GHz to the IF Processor. The 64-QAM Modem performs the modulation and demodulation of the payload (OC-3 or Fast Ethernet or Scalable Ethernet), and forward error correction using advanced modulation and coding techniques. Using all-digital processing, the 64-QAM Modem uses robust modulation and forward error correction coding to minimize the number of bit errors and optimize the radio and network performance. The 64-QAM Modem also scrambles, descrambles and CarrierWave Digital Radio MK-MAN-01 2-12 System Description interleaves/deinterleaves the data stream in accordance with Intelsat standards to ensure modulation efficiency and resilience to sustained burst errors. The modulation will vary by application, data rate, and frequency spectrum. The highest order modulation mode supported is 64 Quadrature Amplitude Modulation (QAM). Table 2-4 summarizes the TCM/convolutional code rates for each modulation type supported by the Digital Radio. Table 2-4.

, 7/8, 11/12 4/5, 9/10 5/6, 11/12 The IDU also provides the physical interface for the user payload and network management. In transmit mode, the Framer merges user payload (OC-3 or Fast Ethernet) with radio overhead-

encapsulated network management data. This combined data stream is transmitted without any loss of user bandwidth. In the receive mode, the Framer separates the combined data stream received from the 64-QAM Modem. The IDU supports Scalable Ethernet data rates, such as 25 or 50 Mbps via the 100BaseT data interface port. The IDU provides network management data on 10 Mbps ports accessible via the 10/100BaseTX port. The Central Processor Unit (CPU) provides the embedded control and network element functionality of the OAM&P. The CPU also communicates with other functions within the IDU for configuration, control, and status monitoring. The CPU passes appropriate status information to the IDU front panel display. The power supply converts 48 Vdc to the DC voltage levels required by each component in the system. 2.6 Consecutive Point Architecture The consecutive point network architecture is based upon the proven SONET/SDH ring. Telecommunications service providers traditionally use the SONET/SDH ring architecture to implement their access networks. A typical SONET/SDH network consists of the service providers Point of Presence (POP) site and several customer sites with fiber optic cables connecting these sites in a ring configuration (see Figure 2-7). This architecture lets providers deliver high bandwidth with high availability to their customers. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 2-13 Figure 2-7. Ring Configuration. SONET/SDH rings are inherently self-healing. Each ring has both an active path and a standby path. Network traffic normally uses the active path. Should one section of the ring fail, the network will switch to the standby path. Switchover occurs in seconds. There may be a brief delay in service, but no loss of payload, thus maintaining high levels of network availability. The consecutive point architecture implemented in the CarrierWave Digital Radio family is based on a point-to-point-to-point topology that mimics fiber rings, with broadband wireless links replacing in-ground fiber cable. A typical consecutive point network consists of a POP and several customer sites connected using CarrierWave units. These units are typically installed in pairs in a building. Each unit installed at a customer site is logically connected to two other units. These connections are as follows:

An over-the-air radio frequency (RF) link to a unit at an adjacent site A back-to-back Ethernet cable link to another unit in the same building through a switch Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and in-building connections is repeated at each site until all buildings in the network are connected in a ring as shown in Figure 2-8. CarrierWave Digital Radio MK-MAN-01 2-14 System Description Figure 2-8. Consecutive Point Network MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 2-15 2.7 Power Management RF power management is a radio design feature that controls the power level (typically expressed in dBm) of the RF signal received from a transmitter by a receiver. The traditional goal of power management is to ensure that the RF signal at a receiver is strong enough to maintain the radio link under changing weather and link conditions. Traditional power management techniques such as Constant Transmit Power Control (CTPC) and Automatic Transmit Power Control (ATPC) transmit at a high power level to overcome the effects of fading and interference. However, these techniques continue to operate at a higher power level than needed to maintain the link in clear weather. Because transmit power remains high when the weather clears, the level of system interference increases. Radios operating at high transmit power will interfere with other radios, even if the interfering source is miles away from the victim. High interference levels can degrade signal quality to the point that wireless radio links become unreliable and network availability suffers. The traditional solution to system interference is to increase the distance between radios. However, the resulting sparse deployment model is inappropriate for metropolitan areas. In response to the need for a high-density deployment model the CarrierWave use a unique power control technique called AdTPC. AdTPC enables CarrierWave units to transmit at the minimum power level necessary to maintain a link regardless of the prevailing weather and interference conditions. The CarrierWave is designed and manufactured to not exceed the +30 dBm maximum power allowed. The purpose of power management is to minimize transmit power level when lower power levels are sufficient. AdTPC also extends the concept of power management by controlling not only the power (dBm) of the RF signal, but its quality (signal-to-

noise ratio) as well. In contrast to ATPC, the AdTPC technique dynamically adjusts the output power based on both the actual strength and quality of the signal. Networked CarrierWave units constantly monitor receive power and maintain 10-12 BER performance under varying interference and climate conditions. Each CarrierWave unit can detect when there is a degradation in the received signal level of quality and adjust the transmit power level of the far-end CarrierWave unit to correct for it. AdTPC provides maximum power in periods of heavy interference and fading and minimum power when conditions are clear. Minimal transmit power reduces potential for co-channel and adjacent channel interference with other RF devices in the service area, thereby ensuring maximum frequency re-use. The resulting benefit is that operators are able to deploy more CarrierWave units in a smaller area.

CarrierWave Digital Radio Back-to-Back Testing Configuration 3.4 Overview of Installation and Testing Process The installation and testing process is accomplished by performing a series of separate, yet interrelated, procedures, each of which is required for the successful implementation of a production CarrierWave Digital Radio network. These procedures are as follows:

Site Evaluation: gathering specific information about potential CarrierWave Digital Radio installation sites. Cable and Installation: Testing and installing CarrierWave ODU cables and optional interface devices at installation sites. CarrierWave ODU Mounting and Alignment: Mounting ODUs to a pole or wall, performing link alignment and radio frequency (RF) verification. CarrierWave Digital Radio Configuration: Using CarrierWave Link Manager software to install network- and site-specific parameters in the radios. CarrierWave Digital Radio Testing: Performing cable continuity checks and RF tests for links, the payload/radio overhead channel, and the management channel.

This information is critical to the successful design and deployment of a network. Site evaluations are required to confirm whether or not a building meets network design requirements. The main objectives are as follows:

Confirm Line of sight for each link CarrierWave Digital Radio ODU mounting locations Site equipment locations Cable routes Any other potential RF sources Prepare site drawings and record site information 3.5.1 Preparing for a Site Evaluation The following tools are required to perform a site evaluation:

RF and network design diagrams (as required) Binoculars Global positioning system (GPS) or range finder Compass Measuring tape and/or wheel Digital camera Area map Aerial photograph (if available) List of potential installation sites (targeted buildings) The following tasks must be completed prior to performing a site evaluation:

Prepare the initial network design by performing the following:

CarrierWave Digital Radio MK-MAN-01 3-6 Identify potential buildings by identifying targeted customers (applicable if youre a service provider) Identify potential links by selecting buildings based on the high probability of line of sight Installation Arrange for access with the facility personnel into the buildings, equipment rooms, and architectural plans to become familiar with the location of all ducts, risers, etc. 3.5.2 Site Evaluation Process The following steps must be completed to perform a successful site evaluation. Each step in the process is detailed in the following subparagraphs:

Ensure RF Safety compliance: Ensure that appropriate warning signs are properly placed and posted at the equipment site or access entry. For a complete list of warnings, refer the Safety Precautions listed at the beginning of this manual. Ensure Compliance with Laws, Regulations, Codes, and Agreements: Ensure that any installation performed as a result of the site evaluation is in full compliance with applicable federal and local laws, regulations, electrical codes, building codes, and fire codes. Establish Line of Sight between CarrierWave Digital Radios: The most critical step in conducting a site evaluation is confirming clear Line of Sight (LOS) between a near CarrierWave Digital Radio and a far CarrierWave Digital Radio. If LOS does not exist, another location must be used. CarrierWave Radios in a link must have a clear view of each other, or line of sight. Binoculars may be used evaluate the path from the desired location of the near CarrierWave Radio to the desired location of the far CarrierWave Radio. To confirm Line of Sight:

- Ensure that no obstructions are close to the transmitting/receiving path. Take into consideration trees, bridges, construction of new buildings, unexpected aerial traffic, window washing units, etc.

- Ensure that each CarrierWave Digital Radio can be mounted in the position required to correctly align the CarrierWave Digital Radio with its link partner. Determine CarrierWave ODU Mounting Requirements: CarrierWave ODUs can be mounted on an antenna mast, brick, masonry or wall. Refer to detailed installation sections. Determine CarrierWave IDU Installation Location: CarrierWave IDUs can be installed tabletop or cabinet, wall mount, or rack mount. The site must provide DC power. Refer to detailed installation sections. Document Potential Sources of Colocation Interference: When CarrierWave ODUs are located on a roof or pole with other transmitters and receivers, an interference analysis may be required to determine and resolve potential interference issues. The interference analysis needs to be performed by an RF engineer. The specific information required for each transmitter and receiver includes the following:

MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-7

- Transmitting and/or receiving frequency

- Type of antenna

- Distance from CarrierWave ODU (horizontal and vertical)

- Polarity (horizontal or vertical)

- Transmit power level

- Antenna direction Measure the Link Distance: The two ways to measure link distance are as follows:

- GPS: record the latitude and longitude for the near and far CarrierWave ODU sites and calculate the link distance. Record the mapping datum used by the GPS unit and ensure the same mapping datum is used for all site evaluations in a given network.

- Range finder: measure the link distance (imperial or metric units may be used). Once the link distance has been measured, verify that the link distance meets the availability requirements of the link. Select the Grounding Location for both the CarrierWave ODU and IDU: The CarrierWave Digital Radio must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires

- Grounding all ODUs as specified in the Installation section

- Grounding all IDUs to the rack. Determine the Length of Interconnect Cable from ODU to IDU: The primary consideration for the outdoor interconnect cable from the ODU to IDU is the distance and route between the ODU and IDU. This cable should not exceed 300 feet using Times Microwave LMR-400 cable. Longer lengths and distances are possible, but require higher quality cable, as illustrated in the table below. Cable Type Loss at 2.5 GHz

(dB/100 ft.) Cable Length Allowed (ft.) LMR-200 LMR-300 LMR-400 LMR-600 LMR-900 16.9 10.4 6.8 4.4 3.0 120 200 300 450 650 Listed cable types are from Times Microwave, equivalent cable from other manufacturers may be used CarrierWave Digital Radio MK-MAN-01 3-8 Installation Confirm the Presence of DC Power for the CarrierWave IDU. Ensure Building Aesthetics: The CarrierWave ODUs streamlined exterior is designed to complement building aesthetics. Ensure that the ODU can be mounted so that it is aesthetically pleasing to the environment and to the property owner. Aesthetics must be approved by the property owner and the network engineer. Take Site Photographs Sketch the Site 3.5.3 Critical System Calculations 3.5.3.1 Received Signal Level (RSL) and Link Budget The received signal level (RSL) can be estimated using the following formula:

RSL (dBm) = PTX + GTX ANT LPath + GRX ANT Where: PTX is the transmitter output power (in dBm) GTX ANT is the gain of the transmit antenna (in dB), 23 dBi for ODUs internal antenna GRX ANT is the gain of the receive antenna (in dB), 23 dBi for ODUs internal antenna LPath is the Path loss, defined by:

LP (dB) = 36.6 + 20log10(F*D) Where: F is the Frequency in MHz (5800), D is the Distance of path in miles This link budget is very important in determining any potential problems during installation. The expected RSL and measure RSL should be close (+/- 5 to 10 dB) 3.5.3.2 Fade Margin Calculation The fade margin is the difference between the actual received signal and the CarrierWave Digital Radios threshold for the modulation mode selected. The fade margin can be used to determine availability and should be at least 10 dB. 3.5.3.3 Availability Calculation Availability of the microwave path is a prediction of the percent of time that the link will operate without producing an excessive BER due to multipath fading. Availability is affected by the following:

Path length Fade margin MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-9 Frequency Terrain (smooth, average, mountainous, valleys) Climate (dry, temperate, hot, humid) Depending on the type of traffic carried over the link and the overall network design redundancy, fade margin should be included to support the desired availability rate. Critical data and voice may require a very high availability rate (99.999% or 5.3 minutes of predicted outage per year). To improve availability, the fade margin can be increased by shortening the path length, transmitting at a higher power level, or by using higher gain antennas. Availability can be computed using the following formula, which is known as the Vigants Barnett Method. Availability = 100

(1 P) P = 2.5 10-9 C F D3 10(-FM/10) Where F is the frequency in MHz (5800) D is the distance in miles FM is the fade margin in dB C is the climate/terrain factor as defined below:

Humid/Over Water: C = 4 (worst case channel) Average Conditions: C = 1 Dry/Mountains: C = 0.25 (best case channel) Example: Assume 21 dB fade margin, over 5 miles with average climate/terrain. The availability comes out to be 99.9986. This corresponds to the link being unavailable for 7.6 minutes per year. 3.5.3.4 Frequency Plan Determination When configuring CarrierWave Digital Radios in a point-to-point or consecutive point configuration, careful engineering of the CarrierWave Digital Radio frequency plans and antenna locations should be performed in order to minimize potential interference between nearby radios. Nearby radios should operate on different frequencies, transmitting in the same band (high side or low side). When designing multi-radio configurations, antenna size, antenna polarization, and antenna location are critical. The frequency plan must be selected based on desired data rate and expected link conditions. In a high interference environment or with lower gain antennas, higher bandwidth, more robust modulation formats must be employed. The available frequency plans are illustrated in Figure 3-

CarrierWave Digital Radio Channel Frequency Plans 3.5.3.5 Antenna Planning The ODU comes with a built in 23 dBi gain antenna. This should provide adequate link performance for most applications. Larger antennas have the advantage of providing narrower beamwidths and high isotropic gain, which yields better link performance (higher fade margin, better availability), and improves immunity to spatial interference (due to the smaller beamwidths). However, larger antennas are more costly to purchase and install than smaller antennas and in some cases, they require special equipment for installation due to narrower beamwidths. They are also more easily affected by wind. Only directional antennas can be used with the CarrierWave Digital Radios. Consult factory for antenna manufacturer options. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-11 The ISM band does not restrict antenna gain or EIRP, therefore there is no need to back off transmit power due to excessive antenna gain. 1. Select where the cable will enter the building from the outside. 2. Determine the length of cable required. Allow three extra feet on each end to allow for strain relief, as well as any bends and turns. 3.5.4 Documenting a Site Evaluation Use the site evaluation form provided on the following pages to document the results of your site evaluation.

IDU Installation ODU Installation 3.6.1 Installing the CarrierWave IDU The CarrierWave IDU can be installed in the following three options:

1. Table top or cabinet 2. Wall mount 3. Rack mount The CarrierWave IDU should be:

Located where you can easily connect to a power supply and any other equipment used in your network, such as a router or PC. In a relatively clean, dust-free environment that allows easy access to the rear panel connectors as well as the front panel controls and indicators. Air must be able to pass freely over the chassis. Accessible for service and troubleshooting. Protected from rain and extremes of temperature (it is designed for indoor use). 3.6.1.1 Installing on a Table Top or Cabinet The CarrierWave IDU can be placed on a tabletop or cabinet shelf. In order to prevent possible disruption, it is recommended to use a strap to secure the IDU. 3.6.1.2 Installing on a Wall An installation option for the IDU is mounting the unit to a wall. Consult factory for details. If the wall mount option is being considered, plan to position the CarrierWave IDU at a height that allows LEDs, the display on the front panel, and the rear connectors to be visible at all times and easily accessible. Also, including plastic clamps to support and arrange the ODU/IDU Interconnect Cable should also be considered. 3.6.1.3 Installing in a Rack To maintain good airflow and cooling, it is preferred that the CarrierWave IDU in a slot that has blank spaces above and below the unit. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-15 To rack-mount the IDU, use the supplied mounting brackets (CarrierComm part number 82-

3184A01) to secure the chassis to the rack cabinet. As shown in Figure 3-4, the brackets can be attached at any of four points on the sides of the enclosure front, back, middle facing front, and middle facing back. This flexibility ensures compatibility with most rack mounting arrangements. Figure 3-4. CarrierWave IDU Dimensions 3.6.2 Installing the CarrierWave ODU There are three options for mounting the CarrierWave ODU Antenna mast Pole Building Each site must be assessed for the mounting method, location, and height. After defining the mounting location and height for the CarrierWave ODU, re-confirm the line of sight. CarrierWave Digital Radio MK-MAN-01 3-16 Installation Tools and Equipment required for installation of the ODU:

Tools Required Equipment Required Compass and protractor inch grounding rod Grounding clamp Grounding wire Coaxial cable assembly

#6 wood screws Cable clips Anchor sleeves Area map Phillips-head screwdriver Flat-head screwdriver Hammer or mallet Power drill 1/8 inch drill bit inch masonry drill bit 5mm hex (Allen) wrench Bubble level or plumb line Adjustable wrench Wire snake (if routing cable through interior walls) 3.6.2.1 Installing the Mounting Poles First install the mounting poles, on which you will mount the CarrierWave ODU. The mounting pole J bracket is optional equipment. Consult factory for supply and part number. It is important to note the direction in which the ODU will point when installing the mounting pole. The mounting pole must be mounted in a vertical position. Failure to do so may result in improper alignment of the ODU. If you need to tilt the ODU to avoid self-interference, you should use a tilt (optional) bracket. Consult factory for tilt bracket. The mounting pole must be grounded. 3.6.2.1.1 Installing on an Antenna Mast 1. Position the mounting pole on the antenna mast. The mounting pole J-bracket is optional equipment. Consult factory for supply and part number. 2. Insert the U-bolts around the mast and through the holes in the mounting pole. Install a washer and nut to each side of the threaded U-bolt and hand tighten. Repeat this step for the second U-bolt. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-17 3. Tighten nuts equally until mounting pole is secure and cannot rotate. Typically 2 inch Figure 3-5. Optional Mounting Pole J Bracket Installed on Pole or Antenna Mast 3.6.2.1.2 Installing on Brick or Masonry 1. Place the mounting plate against the wall. Use a level or plumb line to set the mounting pole perpendicular to the ground (J-bracket is optional, consult factory for supply and part number). 2. Mark the hole locations. 3. Set the pole aside. 4. Drill inch holes at the marked locations. Drill the holes approximately inch deep. 5. Insert the expansion shields into the drilled holes and tap them home. 6.

Tilt Bracket CarrierWave Digital Radio MK-MAN-01 3-20 Installation Figure 3-11. CarrierWave ODU with Mounted Tilt Bracket 3.6.3 Routing the ODU/IDU Interconnect Cable 1. Select where the cable will enter the building from outside. 2. Determine the length of cable required. Allow three extra feet on each end to allow for strain relief, as well as any bends and turns. 3. Route the cable. The ODU and IDU are equipped with N-type female connectors at their interconnecting ports. A length of coaxial cable (such as Times Microwave Systems LMR-400, LMR-300 or LMR-200) fitted with two N-type male connectors is required to connect the ODU to the IDU. This cable assembly may be supplied in fixed lengths with the digital radio. Bulk coaxial cable of equivalent specification may also be used, with terminating connectors applied during cable installation. Based on an evaluation of the cable routing path, pull the ODU/IDU Interconnect cable from one unit to the other, utilizing cable trays, ducts, or conduit as required. Take care that the ODU/IDU Interconnect cable is not kinked or damaged in any way during installation. Be sure to protect the N-type connectors from stress, damage and contamination during installation (do not pull the cable by the connectors). If multiple ODU/IDU Interconnect cables are to be installed along the same route, the cables should all be pulled at one time. Be sure the installed cable does not have any bends that exceed the specified cable bend radius. The ODU/IDU Interconnect cable should be adequately supported on horizontal runs and should be restrained by hangers or ties on vertical runs to reduce stress on the cable. Outside the building, support and restrain the cable as required by routing and environmental conditions (wind, ice). The CarrierWave ODU/IDU and interconnection must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires that the ODU, any mounting pole or mast and any exposed interconnect cable be grounded on the outside of the structure. The IDU must be grounded to a rack or structure ground that also has direct path to earth ground. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-21 The ODU must be directly connected to a ground rod or equivalent earth ground. The ODU/IDU interconnect cable should also be grounded at the ODU, where the cable enters the structure and at intermediate points if the exposed cable run is long (typically at intervals of 100 ft), with the cable manufacturers grounding kits. Lightning protection devices used with the interconnect cable must be appropriate for the transmission of the interconnect signals (DC to 2.4 GHz). Provide a sufficient but not excessive length of cable at each end to allow easy connection to the ODU and IDU without stress or tension on the cable. Excessive cable length, especially outdoors, should be avoided to minimize signal attenuation and provide a more robust and reliable installation. If installing using bulk coaxial cable, terminate the ODU/IDU Interconnect cable at each end with an N-type male connector appropriate for the cable type. Use of connectors, is recommended. termination procedures specified by the cable manufacturer tools and Once the cable has been installed but before connection has been made to either unit, a simple DC continuity test should be made to verify the integrity of the installed cable. A DC continuity tester or digital multimeter may be used verify a lack of DC continuity between the cable center conductor and outer conductor, with the opposite end of the cable unconnected. With a temporary test lead or shorting adapter connected to one end of the cable, DC continuity should be verified between the center and outer conductors at the opposite end. 3.6.3.1 Installing the ODU/IDU Interconnect Cable 1. Screw on the ODU/IDU Interconnect cable with N-type connector. Figure 3-12. N-type Connector Location Underside of CarrierWave ODU 2. Insert the N-type connector into the receptacle located underneath the ODU. Make sure that the connector tab engages the slot in the receptacle. 3. Slide the grommet up the cable and press it into the bottom of the ODU. 3.6.4 Grounding the System The CarrierWave IDU/ODU System must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires:

1. Grounding all the ODUs as shown in Figure 3-13. CarrierWave Digital Radio MK-MAN-01 3-22 Installation 2. Grounding the IDU to the rack. 3.6.4.1 Grounding the ODU 1. Place the grounding rod so as to allow for the shortest possible path from the grounding cable to the ODU. 2. Drive the grounding rod into the ground at least eight inches from the ground surface. 3. Attach a grounding clamp to the grounding rod. You will use this clamp to attach grounding wires for both the ODU and indoor junction box, reference Figure 3-13. Figure 3-13. Ground Connections to ODU 4. Connect a ground lug to one end of the grounding wire. 5. Remove one of the lower mounting screws of the mounting pole. Insert a screw through the grounding lug terminal and re-install it to the mounting pole. 6. Attach the grounding wire to the clamp on the grounding rod, reference Figure 3-14. If necessary, use wire staples to secure the grounding wire to the outside wall. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-23 Figure 3-14. Mounting Pole with Ground Lug 7. Install a grounding wire from the junction box to the grounding rod. 3.6.4.2 Grounding the IDU 1. Remove the nut and ring lug terminal from the IDU Chassis GND stud. 2. The provided ring lug crimp terminal is intended to be used with 18 AWG wire (provided by the customer). The IDU should be able to be connected to a system or building electrical ground point (rack ground or power third-wire ground) with a cable of 36 or less. 3. Crimp the ring lug terminal to one end of the wire to be used as the IDU ground wire. Connect the opposite end of the IDU ground wire to the local source of ground in an appropriate manner. 4. Place the ring lug of the IDU ground cable on the IDU Chassis GND stud. 5. Place the nut on the IDU Chassis GND stud and tighten appropriately. 3.7 Configuration of the CarrierWave Digital Radio Configuration of the CarrierWave Digital Radio IDU does not require a connection to the ODU. It is suggested to configure the IDU prior to connecting to the ODU. 3.7.1 Materials Required The following items are needed to configure an IDU:

>CarrierComm->vX-XX->IC menu (or iConductorTM software. 3.7.2.2 Connecting the IDU to the PC and Power Source Perform the following steps to ensure the IDU is powered up and connected to you PC:

1. To connect to the IDU DC power connector (located on the IDU rear panel), an IDU power cable is required. A mating power cable connector (Phoenix Contact P/N 17 86 83 1) is provided with the CarrierWave IDU for construction of this cable. This connector has screw clamp terminals that accommodate 24 AWG to 12 AWG wire. The recommended wire size for construction of power cables under 10 feet in length, supplying 48 V dc, is 18 AWG. The opposite end of the IDU power cable should have a termination appropriate for the power supply being used. The IDU power cable should be of sufficient length to avoid tension in the cable and provide a service loop for connection, but not be of excessive length. Stranded wire should be used over a solid conductor to reduce tension on the IDU DC Power connector. Using the supplied power cable connector, pin 2 (labeled -V) should be connected to the power supply terminal supplying 48 V dc, while pin 1 (labeled RET) should be connected to the power supply return. Refer to Figure 3-15. Note that pin 1 (RET) of the IDU DC Power connector is connected to the IDU chassis ground internal to the IDU. Use of a power supply with an inappropriate ground reference may cause damage to the IDU and / or the supply. 2. Connect the IDU power cable to the 48 V dc power supply, and place the voltmeter probes on the unconnected IDU end of the power cable, with the positive voltmeter probe on pin 2

(-V) of the cable connector and the negative probe on pin 1(RET). The connector screw terminal screw heads may be used as convenient monitor points. Refer to Figure 3-15. 3. Turn on the 48 V dc supply. Verify that the digital voltmeter reads between 44 V dc and 52 V dc when monitoring the cable points specified above. Adjust the power supply output voltage and/or change the connections at the power supply to achieve this reading. 4. With the negative voltmeter probe still on pin 1 (RET) of the power cable connector (and the power supply still on), press the positive voltmeter probe to the IDU chassis and verify a potential of zero volts between the IDU chassis and cable pin 1 (RET). If the measured potential is not zero, the power supply may be grounded incorrectly and should not be used in this condition with an IDU. Note that this measurement assumes that the IDU is installed and properly grounded. If this is not the case, the same measurement can be made between cable pin 1 (RET) and a convenient ground (such as an ac outlet third-wire ground). 5. Turn the 48 V dc supply off. 6. Plug the IDU power cable into the IDU rear panel DC Power connector (DC Input). Place the voltmeter probes on the cable connector screw terminal screw heads as per step 2 above. Refer to Figure 3-15. Note that the CarrierWave Digital Radio IDU does not have a power on/off switch. When DC power is connected, the digital radio powers up and is operational. There can be up to 200 mW of RF power present at the antenna port. The antenna should be directed safely when power is applied. 7. Turn on the 48 V dc power supply, and verify that the reading on the digital voltmeter is as specified in step 3 above. CarrierWave Digital Radio MK-MAN-01 3-26 8. Turn the 48 V dc supply off. Installation 9. Connect the IDU to the laptop computer, using the Cat-5 Ethernet crossover cable or connect the IDU to a computer network, using a normal Cat-5 Ethernet cable. Connect the Ethernet cable to OAMP 10/100BaseTX Ch1 connector on the IDU rear panel. Refer to Figure 3-16 for the IDU rear panel connections. 2 1 Figure 3-15.

This includes:

LCD display (including screen menus) Cursor and screen control buttons LED status indicators 4.2 Front Panel Operation The CarrierWave IDU front panel is depicted in Figure 4-1 below. All models of the CarrierWave Digital Radio family have this standardized front panel and chassis. Figure 4-1. CarrierWave IDU Front Panel 4.2.1 LCD Display The Liquid Crystal Display (LCD) on the CarrierWave IDU front panel provides status, control, and configuration functionality. The front panel used on the CarrierWave IDU has a 20 character wide by 4 character high LCD display that is capable of displaying ASCII characters in any position on the screen. The menu navigation and various screens are explained in detail later in this section. CarrierWave Digital Radio MK-MAN-01 4-2 Front Panel Operation 4.2.2 Cursor and Screen Control Buttons The buttons on the CarrierWave Digital Radio front panel are used for LCD screen interface and control functions. The unit has 6 buttons for user input (Up, Down, Left, Right, Enter, and Escape) as depicted in the figure below. Used to accept an entry (such as a value, a condition, or a menu choice. Enter Escape Used to back up a level in the menu structure without saving any current changes.

<LEFT>, <RIGHT> Used to scroll through valid values of a selection element or to move a blinking cursor within the data field of an edit element.

<UP>, <DOWN> Used to scroll between the menu items. If the down arrow is pressed when the cursor is at the bottom of the screen and there are more menu items below, the screen will scroll down one line. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 4-3 4.3 LED Status Indicators The basic operation of the CarrierWave Digital Radio can be checked by viewing the LED indicators on the front panel. Normally, only green LEDs should be lit. A yellow LED indicates potential system degradation, though the link is still active and operational. A red LED is an alarm indicator. If it is lit, it indicates a potential problem in the radio system. Refer to Figure 4-2 and the table that follows for a detailed explanation of the LED indicators.

NMS CPT Consecutive Point NMS Port When this LED is illuminated it indicates that there is a connection to the remote or Consecutive Point NMS port. 4.4 Screen Menus The front panel used on the CarrierWave IDU has a 20 character wide by 4 character high LCD display that is capable of displaying ASCII characters in any position on the screen. The unit has 6 buttons for user input: Up, Down, Left, Right, Enter, and Escape. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 4-5 There are two basic screen types used to build the interface application, Text Screens and Menu Screens. 4.4.1 Text Screens Text screens are used to display information to the user, but do not allow for any user input. 4.4.1.1 Display When the screen is displayed on the LCD panel the first four lines are visible, and if there are more than four lines in the screen, a plus (+) sign is displayed in the lower right hand corner of the display. 4.4.1.2 Buttons The Enter, Left, and Right buttons do nothing on a text screen. If the screen contains more than four lines the Up and Down buttons scroll up and down one line at a time. The Escape button navigates to the previously viewed screen. 4.4.1.3 Example Figure 4-3. OA&M Parameter Display 4.4.2 Menu Screen Menu screens are used to navigate around the system and for data entry. Each menu is composed of menu elements that serve different purposes. There are currently four menu element types, Text, Command, Selection, and Edit. 4.4.2.1 Display Each line is one menu element as described above. Normally the first line is a Text element, which is the title of the menu. When the menu is scrolled, the title remains fixed while the bottom three lines scroll. The plus (+) sign is displayed in the bottom right corner to indicate that there are more lines below just as in the Text Screen. A menu screen has a cursor that is displayed as an asterisk (*) in the left most character position and indicates the active element. When the screen is entered the cursor is on the second line

(first line below the title). CarrierWave Digital Radio MK-MAN-01 4-6 Front Panel Operation The display characteristics of the different menu element types differ slightly. The text element is centered horizontally in the display. The command element is also text but is left justified with room for the cursor. Both the selection and edit types have a label that is left justified, then a colon, then the data field. 4.4.2.2 Buttons All buttons are active on a menu screen, depending on the type of the active element. The Up and Down buttons move the cursor up and down, changing the active element. If the cursor is on the bottom row, there are more rows below, and the Down button is pressed, the bottom three lines scroll upward exposing the next line. The Up button has the same behavior in the opposite direction. The Escape button will always navigate to the previously viewed screen. The Enter, Left, Right, Up, and Down button behaviors differ slightly depending on the type of the active menu element and will be described below. If the active element is a command element, the Left and Right buttons have no effect and the Up and Down buttons will behave as detailed above. The Enter button executes the command associated with that element. The command can be a navigation command that takes the user to another screen, or action command that performs an action. If the active element is a selection element, the Left and Right buttons scroll through a list of valid values, displaying the currently selected value on the right side of the active line on the screen. The Up and Down buttons still have their normal behavior of moving the cursor up or down to a different element. The Enter button will execute a command passing the selected value. If the active element is an edit element, the Up and Down buttons still have their normal behavior until the Right button is pressed. The Left and Right buttons move a blinking cursor within the data field to facilitate editing that field. Once the blinking cursor is in the data field, the Up and Down buttons scroll through a list of valid characters for that field, allowing limited data entry. If the blinking cursor is on the first character of the data field and the Left button is pressed, the blinking cursor disappears and the Up and Down buttons behave normally again. As with the selection element, the Enter button executes a command and passes the data field to the command. 4.4.2.3 Examples Figure 4-4. Menu Screen with Command elements MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 4-7 Figure 4-5. Menu Screen with one Command and two Edit elements 4.5 Menu Tree Structure This section shows the hierarchy of the menu system. In general, <ENTER> will take you to the next screen from a menu choice, <UP> or <DOWN> will scroll through screens within a menu choice, and <ESC> will take you back up one menu level. The dashed lines indicate the bottom of the screen to show lower (or upper) entries, use <UP> or <DOWN>. CarrierWave Digital Radio MK-MAN-01 4-8 Front Panel Operation CarrierWave

RF Energy Health Hazard The radio equipment described in this guide uses radio frequency transmitters. Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard. Do not allow people to come in close proximity to the front of the antenna while the transmitter is operating. The antenna will be professional installed on fixed-mounted outdoor permanent structures where the antenna will be 2 meters away from any other antenna and all persons. Protection from Lightning Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building. The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode. FCC Notice, USA CarrierWave Digital Radios comply with Part 15 of the FCC rules. The radios are specifically designed to be used under Part 15, Section 15.247 of the FCC rules and regulations. Operation is subject to following conditions:

The device to utilize a fixed mount antenna, for use on a permanent outdoor structure. The device to be installed by qualified installation/deployment personnel, and a minimum of 2 meter of separation must exist between the device and persons, when the device is operating. The device installers and operators should be aware of the transmitter operating conditions, specified in the installation manual and other associated user documentation, as well as the antenna co-location requirements of Part 1.1307 (b) (3), of FCC rules, pertaining to RF exposure. The device may not cause harmful interference. The device must accept interference received, including interference that may cause undesired operation. CarrierWave Digital Radio MK-MAN-01 1-2 Safety Precautions The device is intended to be used only when installed in accordance with instructions outlined in this manual. Failure to comply with these instructions may void the user's authority to operate this device and/or the manufacturer's warranty.

MK-MAN-01 CarrierWave Digital Radio 2 System Description 2.1 About This Manual This manual is written for those who are involved in the hands-on installation of the CarrierWave Digital Radio, such as installation technicians, site evaluators, project managers, and network engineers. It assumes the reader has a basic understanding of how to install hardware, use Windows based software, and operate test equipment. 2.2 Introduction The CarrierWave family of digital license-free radios provides high capacity transmission, flexibility, features, and convenience for wireless digital communications networks. The CarrierWave digital radios are spectrum and data rate scalable, enabling service providers or organizations to trade-off system gain with spectral efficiency and channel availability for optimal network connectivity. CarrierComms digital radio family enables service providers and enterprises to offer a portfolio of secure, scalable wireless applications for data, video, and Voice over IP (VoIP). The CarrierWave digital radio family operates in the Industrial, Scientific, and Medical (ISM) band of 5.725 to 5.850 GHz, which is typically referred generically as 5.8 GHz. The CarrierWave Digital Radio family supports two types of user data payload connectivity:

SONET/SDH wireless bridging between two fixed coordinated locations without the delay and expense of trenching fiber or the added costs of leasing dedicated OC-3 lines. 100Base-TX intelligent bridging between two locations without the delay and expense of installing cable or traditional microwave

- Scalable Ethernet capability of 25 and 50 Mbps is included. These scalable radios provide LAN connectivity and offer performance trade-offs between operational bandwidths, data rates, and distance. For customers such as cellular carriers requiring backhaul and backbone extension as well as service providers requiring network redundancy, new Points of Presence (POPs), and last mile access, the CarrierWave-155 radio is a cost effective alternative to leased lines with carrier-class quality of performance. The CarrierWave-100 radio is a cost effective solution to meet the growing demand for enterprise Local Area Network (LAN) connectivity between buildings and campuses as well as service providers requiring reliable products for infrastructure expansion, extending Metropolitan Area Network (MAN) fiber access, and network redundancy. CarrierWave Digital Radio MK-MAN-01 2-2 System Description The CarrierWave Digital Radio includes integrated Operations, Administration, Maintenance, and Provisioning (OAM&P) functionality and design features enabling simple commissioning when the radio network is initially set up in the field at the customers premises. Furthermore, a highlight of CarrierComms radio products is scalability and the capability to support a ring-type architecture. This ring or consecutive point radio architecture is self-healing in the event of an outage in the link and automatically re-routes data traffic, thereby ensuring that service to the end user is not interrupted. The overall architecture consists of a single 2RU rack mount Indoor Unit (IDU) with a cable connecting to an Outdoor Unit (ODU) with an integrated antenna. There is an option for interfacing the ODU with an external antenna (contact factory for availability). The IDU/ODU architecture is advantageous when compared to a single IDU with external mount antenna since supporting a signal of 5.8 GHz from the IDU rack to the antenna will experience significant signal degradation requiring expensive coaxial cable or waveguide. Figure 2-1. CarrierWave IDU/ODU Architecture Table 2-1 lists key features that CarrierWave technology offers to those involved in the design, deployment and support of broadband fixed wireless networks.

MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 2-9 Power Supply DC Input

-48 VDC

-48v (Isolated Input); 2-pin captive power connector. The CarrierWave Digital Radio requires an input of 37 to 60 volts dc at the rear panel DC Input connector. The total required power is a maximum of 70 W. The IDU rear panel power connector pin numbering is 1 through 2, from left to right, when facing the unit rear panel. Pin 1 is the power supply return and is connected to unit chassis ground internally. Pin 2 should be supplied with a nominal 48 V dc, with respect to the unit chassis (ground). A ground-isolated supply may be used, provided it will tolerate grounding of its most positive output. The recommended power input is 44 to 52 V dc at 2 Amps minimum. It is recommended that any power supply used be able to supply a minimum of 100 W to the IDU. is supplied with A mating power cable connector the CarrierWave IDU. It is a 2-pin plug, 5 mm pitch, manufactured by Phoenix Contact, P/N 17 86 83 1 (connector type MSTB 2,5/2-STF). This connector has screw clamp terminals that accommodate 24 AWG to 12 AWG wire. The power cable wire should be selected to provide the appropriate current with minimal voltage drop, based on the power supply voltage and length of cable required. The recommended wire size for power cables under 10 feet in length supplying 48 Vdc is 18 AWG. The IDU supplies the ODU with all required power via the ODU/IDU Interconnect cable. The CarrierWave Digital Radio IDU does not have a power on/off switch. When DC power is connected to the IDU, the digital radio powers up and is operational. There can be up to 200 mW of RF power present at the antenna port (external antenna version). The antenna should be directed safely when power is applied.

There is an option for interfacing the ODU with an external antenna (consult factory for this option). This IDU/ODU architecture is advantageous when compared to a single IDU with external mount antenna since supporting a signal of 5.8 GHz from the IDU rack to the antenna will experience significant signal degradation requiring expensive coaxial cable or waveguide. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 2-11 Figure 2-6 shows a functional block diagram of the CarrierWave Digital Radio, which consists of an antenna, ODU RF Up/Down Converter with HPA and LNA, IF Processor, 64-QAM Modem, Multiplexer/Demultiplexer, and IDU Front Panel. 2375 MHz 1675 MHz 64-QAM Modem IF Processor Framer MUX IDU/ODU Comm Link 48 V ODU 5.8 GHz Radio with Integrated 23 dBi Antenna IDU 2375 MHz 1675 MHz Radio Control/Status ODU Power 3.3V, 5V, 6V,-12V Control SNMP Payload Multiplexer/Demultiplexer Ethernet Scaler Front Panel

Single T1 supported on SONET IDUs Figure 2-6. CarrierWave System Block Diagram The IDU interfaces with the ODU to receive and provide modulated transmit and receive waveforms. The IDU interfaces provide SONET OC-3 (CarrierWave-155) and Fast Ethernet 100Base-T (CarrierWave-100) connections to the network. In addition, one (SONET model) or two (Ethernet model) T1 channels are provided for PBX extension. SNMP is provided on 10/100BaseT ports. The ODU RF Up/Down Converter card provides the interface to the antenna. The transmit section up converts and amplifies the modulated Intermediate Frequency (IF) of 2.375 GHz from the IF Processor and provides additional filtering. The receive section down converts the received signal, provides additional filtering, and outputs an IF of 1.675 GHz to the IF Processor. The 64-QAM Modem performs the modulation and demodulation of the payload (OC-3 or Fast Ethernet or Scalable Ethernet), and forward error correction using advanced modulation and coding techniques. Using all-digital processing, the 64-QAM Modem uses robust modulation and forward error correction coding to minimize the number of bit errors and optimize the radio and network performance. The 64-QAM Modem also scrambles, descrambles and CarrierWave Digital Radio MK-MAN-01 2-12 System Description interleaves/deinterleaves the data stream in accordance with Intelsat standards to ensure modulation efficiency and resilience to sustained burst errors. The modulation will vary by application, data rate, and frequency spectrum. The highest order modulation mode supported is 64 Quadrature Amplitude Modulation (QAM). Table 2-4 summarizes the TCM/convolutional code rates for each modulation type supported by the Digital Radio. Table 2-4.

, 7/8, 11/12 4/5, 9/10 5/6, 11/12 The IDU also provides the physical interface for the user payload and network management. In transmit mode, the Framer merges user payload (OC-3 or Fast Ethernet) with radio overhead-

encapsulated network management data. This combined data stream is transmitted without any loss of user bandwidth. In the receive mode, the Framer separates the combined data stream received from the 64-QAM Modem. The IDU supports Scalable Ethernet data rates, such as 25 or 50 Mbps via the 100BaseT data interface port. The IDU provides network management data on 10 Mbps ports accessible via the 10/100BaseTX port. The Central Processor Unit (CPU) provides the embedded control and network element functionality of the OAM&P. The CPU also communicates with other functions within the IDU for configuration, control, and status monitoring. The CPU passes appropriate status information to the IDU front panel display. The power supply converts 48 Vdc to the DC voltage levels required by each component in the system. 2.6 Consecutive Point Architecture The consecutive point network architecture is based upon the proven SONET/SDH ring. Telecommunications service providers traditionally use the SONET/SDH ring architecture to implement their access networks. A typical SONET/SDH network consists of the service providers Point of Presence (POP) site and several customer sites with fiber optic cables connecting these sites in a ring configuration (see Figure 2-7). This architecture lets providers deliver high bandwidth with high availability to their customers. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 2-13 Figure 2-7. Ring Configuration. SONET/SDH rings are inherently self-healing. Each ring has both an active path and a standby path. Network traffic normally uses the active path. Should one section of the ring fail, the network will switch to the standby path. Switchover occurs in seconds. There may be a brief delay in service, but no loss of payload, thus maintaining high levels of network availability. The consecutive point architecture implemented in the CarrierWave Digital Radio family is based on a point-to-point-to-point topology that mimics fiber rings, with broadband wireless links replacing in-ground fiber cable. A typical consecutive point network consists of a POP and several customer sites connected using CarrierWave units. These units are typically installed in pairs in a building. Each unit installed at a customer site is logically connected to two other units. These connections are as follows:

An over-the-air radio frequency (RF) link to a unit at an adjacent site A back-to-back Ethernet cable link to another unit in the same building through a switch Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and in-building connections is repeated at each site until all buildings in the network are connected in a ring as shown in Figure 2-8. CarrierWave Digital Radio MK-MAN-01 2-14 System Description Figure 2-8. Consecutive Point Network MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 2-15 2.7 Power Management RF power management is a radio design feature that controls the power level (typically expressed in dBm) of the RF signal received from a transmitter by a receiver. The traditional goal of power management is to ensure that the RF signal at a receiver is strong enough to maintain the radio link under changing weather and link conditions. Traditional power management techniques such as Constant Transmit Power Control (CTPC) and Automatic Transmit Power Control (ATPC) transmit at a high power level to overcome the effects of fading and interference. However, these techniques continue to operate at a higher power level than needed to maintain the link in clear weather. Because transmit power remains high when the weather clears, the level of system interference increases. Radios operating at high transmit power will interfere with other radios, even if the interfering source is miles away from the victim. High interference levels can degrade signal quality to the point that wireless radio links become unreliable and network availability suffers. The traditional solution to system interference is to increase the distance between radios. However, the resulting sparse deployment model is inappropriate for metropolitan areas. In response to the need for a high-density deployment model the CarrierWave use a unique power control technique called AdTPC. AdTPC enables CarrierWave units to transmit at the minimum power level necessary to maintain a link regardless of the prevailing weather and interference conditions. The CarrierWave is designed and manufactured to not exceed the +30 dBm maximum power allowed. The purpose of power management is to minimize transmit power level when lower power levels are sufficient. AdTPC also extends the concept of power management by controlling not only the power (dBm) of the RF signal, but its quality (signal-to-

noise ratio) as well. In contrast to ATPC, the AdTPC technique dynamically adjusts the output power based on both the actual strength and quality of the signal. Networked CarrierWave units constantly monitor receive power and maintain 10-12 BER performance under varying interference and climate conditions. Each CarrierWave unit can detect when there is a degradation in the received signal level of quality and adjust the transmit power level of the far-end CarrierWave unit to correct for it. AdTPC provides maximum power in periods of heavy interference and fading and minimum power when conditions are clear. Minimal transmit power reduces potential for co-channel and adjacent channel interference with other RF devices in the service area, thereby ensuring maximum frequency re-use. The resulting benefit is that operators are able to deploy more CarrierWave units in a smaller area. CarrierWave Digital Radio MK-MAN-01 2-16 System Description 2.8 CarrierWave iWareTM Software and Network Management iWareTM is the software suite that is fully compatible with SNMP (v1) and standard NMS software.

CarrierWave Digital Radio Back-to-Back Testing Configuration 3.4 Overview of Installation and Testing Process The installation and testing process is accomplished by performing a series of separate, yet interrelated, procedures, each of which is required for the successful implementation of a production CarrierWave Digital Radio network. These procedures are as follows:

Site Evaluation: gathering specific information about potential CarrierWave Digital Radio installation sites. Cable and Installation: Testing and installing CarrierWave ODU cables and optional interface devices at installation sites. CarrierWave ODU Mounting and Alignment: Mounting ODUs to a pole or wall, performing link alignment and radio frequency (RF) verification. CarrierWave Digital Radio Configuration: Using CarrierWave Link Manager software to install network- and site-specific parameters in the radios. CarrierWave Digital Radio Testing: Performing cable continuity checks and RF tests for links, the payload/radio overhead channel, and the management channel.

This information is critical to the successful design and deployment of a network. Site evaluations are required to confirm whether or not a building meets network design requirements. The main objectives are as follows:

Confirm Line of sight for each link CarrierWave Digital Radio ODU mounting locations Site equipment locations Cable routes Any other potential RF sources Prepare site drawings and record site information 3.5.1 Preparing for a Site Evaluation The following tools are required to perform a site evaluation:

RF and network design diagrams (as required) Binoculars Global positioning system (GPS) or range finder Compass Measuring tape and/or wheel Digital camera Area map Aerial photograph (if available) List of potential installation sites (targeted buildings) The following tasks must be completed prior to performing a site evaluation:

Prepare the initial network design by performing the following:

CarrierWave Digital Radio MK-MAN-01 3-6 Identify potential buildings by identifying targeted customers (applicable if youre a service provider) Identify potential links by selecting buildings based on the high probability of line of sight Installation Arrange for access with the facility personnel into the buildings, equipment rooms, and architectural plans to become familiar with the location of all ducts, risers, etc. 3.5.2 Site Evaluation Process The following steps must be completed to perform a successful site evaluation. Each step in the process is detailed in the following subparagraphs:

Ensure RF Safety compliance: Ensure that appropriate warning signs are properly placed and posted at the equipment site or access entry. For a complete list of warnings, refer the Safety Precautions listed at the beginning of this manual. Ensure Compliance with Laws, Regulations, Codes, and Agreements: Ensure that any installation performed as a result of the site evaluation is in full compliance with applicable federal and local laws, regulations, electrical codes, building codes, and fire codes. Establish Line of Sight between CarrierWave Digital Radios: The most critical step in conducting a site evaluation is confirming clear Line of Sight (LOS) between a near CarrierWave Digital Radio and a far CarrierWave Digital Radio. If LOS does not exist, another location must be used. CarrierWave Radios in a link must have a clear view of each other, or line of sight. Binoculars may be used evaluate the path from the desired location of the near CarrierWave Radio to the desired location of the far CarrierWave Radio. To confirm Line of Sight:

- Ensure that no obstructions are close to the transmitting/receiving path. Take into consideration trees, bridges, construction of new buildings, unexpected aerial traffic, window washing units, etc.

- Ensure that each CarrierWave Digital Radio can be mounted in the position required to correctly align the CarrierWave Digital Radio with its link partner. Determine CarrierWave ODU Mounting Requirements: CarrierWave ODUs can be mounted on an antenna mast, brick, masonry or wall. Refer to detailed installation sections. Determine CarrierWave IDU Installation Location: CarrierWave IDUs can be installed tabletop or cabinet, wall mount, or rack mount. The site must provide DC power. Refer to detailed installation sections. Document Potential Sources of Colocation Interference: When CarrierWave ODUs are located on a roof or pole with other transmitters and receivers, an interference analysis may be required to determine and resolve potential interference issues. The interference analysis needs to be performed by an RF engineer. The specific information required for each transmitter and receiver includes the following:

MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-7

- Transmitting and/or receiving frequency

- Type of antenna

- Distance from CarrierWave ODU (horizontal and vertical)

- Polarity (horizontal or vertical)

- Transmit power level

- Antenna direction Measure the Link Distance: The two ways to measure link distance are as follows:

- GPS: record the latitude and longitude for the near and far CarrierWave ODU sites and calculate the link distance. Record the mapping datum used by the GPS unit and ensure the same mapping datum is used for all site evaluations in a given network.

- Range finder: measure the link distance (imperial or metric units may be used). Once the link distance has been measured, verify that the link distance meets the availability requirements of the link. Select the Grounding Location for both the CarrierWave ODU and IDU: The CarrierWave Digital Radio must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires

- Grounding all ODUs as specified in the Installation section

- Grounding all IDUs to the rack. Determine the Length of Interconnect Cable from ODU to IDU: The primary consideration for the outdoor interconnect cable from the ODU to IDU is the distance and route between the ODU and IDU. This cable should not exceed 300 feet using Times Microwave LMR-400 cable. Longer lengths and distances are possible, but require higher quality cable, as illustrated in the table below. Cable Type Loss at 2.5 GHz

(dB/100 ft.) Cable Length Allowed (ft.) LMR-200 LMR-300 LMR-400 LMR-600 LMR-900 16.9 10.4 6.8 4.4 3.0 120 200 300 450 650 Listed cable types are from Times Microwave, equivalent cable from other manufacturers may be used CarrierWave Digital Radio MK-MAN-01 3-8 Installation Confirm the Presence of DC Power for the CarrierWave IDU. Ensure Building Aesthetics: The CarrierWave ODUs streamlined exterior is designed to complement building aesthetics. Ensure that the ODU can be mounted so that it is aesthetically pleasing to the environment and to the property owner. Aesthetics must be approved by the property owner and the network engineer. Take Site Photographs Sketch the Site 3.5.3 Critical System Calculations 3.5.3.1 Received Signal Level (RSL) and Link Budget The received signal level (RSL) can be estimated using the following formula:

RSL (dBm) = PTX + GTX ANT LPath + GRX ANT Where: PTX is the transmitter output power (in dBm) GTX ANT is the gain of the transmit antenna (in dB), 23 dBi for ODUs internal antenna GRX ANT is the gain of the receive antenna (in dB), 23 dBi for ODUs internal antenna LPath is the Path loss, defined by:

LP (dB) = 36.6 + 20log10(F*D) Where: F is the Frequency in MHz (5800), D is the Distance of path in miles This link budget is very important in determining any potential problems during installation. The expected RSL and measure RSL should be close (+/- 5 to 10 dB) 3.5.3.2 Fade Margin Calculation The fade margin is the difference between the actual received signal and the CarrierWave Digital Radios threshold for the modulation mode selected. The fade margin can be used to determine availability and should be at least 10 dB. 3.5.3.3 Availability Calculation Availability of the microwave path is a prediction of the percent of time that the link will operate without producing an excessive BER due to multipath fading. Availability is affected by the following:

Path length Fade margin MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-9 Frequency Terrain (smooth, average, mountainous, valleys) Climate (dry, temperate, hot, humid) Depending on the type of traffic carried over the link and the overall network design redundancy, fade margin should be included to support the desired availability rate. Critical data and voice may require a very high availability rate (99.999% or 5.3 minutes of predicted outage per year). To improve availability, the fade margin can be increased by shortening the path length, transmitting at a higher power level, or by using higher gain antennas. Availability can be computed using the following formula, which is known as the Vigants Barnett Method. Availability = 100

(1 P) P = 2.5 10-9 C F D3 10(-FM/10) Where F is the frequency in MHz (5800) D is the distance in miles FM is the fade margin in dB C is the climate/terrain factor as defined below:

Humid/Over Water: C = 4 (worst case channel) Average Conditions: C = 1 Dry/Mountains: C = 0.25 (best case channel) Example: Assume 21 dB fade margin, over 5 miles with average climate/terrain. The availability comes out to be 99.9986. This corresponds to the link being unavailable for 7.6 minutes per year. 3.5.3.4 Frequency Plan Determination When configuring CarrierWave Digital Radios in a point-to-point or consecutive point configuration, careful engineering of the CarrierWave Digital Radio frequency plans and antenna locations should be performed in order to minimize potential interference between nearby radios. Nearby radios should operate on different frequencies, transmitting in the same band (high side or low side). When designing multi-radio configurations, antenna size, antenna polarization, and antenna location are critical. The frequency plan must be selected based on desired data rate and expected link conditions. In a high interference environment or with lower gain antennas, higher bandwidth, more robust modulation formats must be employed. The available frequency plans are illustrated in Figure 3-

CarrierWave Digital Radio Channel Frequency Plans 3.5.3.5 Antenna Planning The ODU comes with a built in 23 dBi gain antenna. This should provide adequate link performance for most applications. Larger antennas have the advantage of providing narrower beamwidths and high isotropic gain, which yields better link performance (higher fade margin, better availability), and improves immunity to spatial interference (due to the smaller beamwidths). However, larger antennas are more costly to purchase and install than smaller antennas and in some cases, they require special equipment for installation due to narrower beamwidths. They are also more easily affected by wind. Only directional antennas can be used with the CarrierWave Digital Radios. Consult factory for antenna manufacturer options. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-11 The ISM band does not restrict antenna gain or EIRP, therefore there is no need to back off transmit power due to excessive antenna gain. 1. Select where the cable will enter the building from the outside. 2. Determine the length of cable required. Allow three extra feet on each end to allow for strain relief, as well as any bends and turns. 3.5.4 Documenting a Site Evaluation Use the site evaluation form provided on the following pages to document the results of your site evaluation.

IDU Installation ODU Installation 3.6.1 Installing the CarrierWave IDU The CarrierWave IDU can be installed in the following three options:

1. Table top or cabinet 2. Wall mount 3. Rack mount The CarrierWave IDU should be:

Located where you can easily connect to a power supply and any other equipment used in your network, such as a router or PC. In a relatively clean, dust-free environment that allows easy access to the rear panel connectors as well as the front panel controls and indicators. Air must be able to pass freely over the chassis. Accessible for service and troubleshooting. Protected from rain and extremes of temperature (it is designed for indoor use). 3.6.1.1 Installing on a Table Top or Cabinet The CarrierWave IDU can be placed on a tabletop or cabinet shelf. In order to prevent possible disruption, it is recommended to use a strap to secure the IDU. 3.6.1.2 Installing on a Wall An installation option for the IDU is mounting the unit to a wall. Consult factory for details. If the wall mount option is being considered, plan to position the CarrierWave IDU at a height that allows LEDs, the display on the front panel, and the rear connectors to be visible at all times and easily accessible. Also, including plastic clamps to support and arrange the ODU/IDU Interconnect Cable should also be considered. 3.6.1.3 Installing in a Rack To maintain good airflow and cooling, it is preferred that the CarrierWave IDU in a slot that has blank spaces above and below the unit. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-15 To rack-mount the IDU, use the supplied mounting brackets (CarrierComm part number 82-

3184A01) to secure the chassis to the rack cabinet. As shown in Figure 3-4, the brackets can be attached at any of four points on the sides of the enclosure front, back, middle facing front, and middle facing back. This flexibility ensures compatibility with most rack mounting arrangements. Figure 3-4. CarrierWave IDU Dimensions 3.6.2 Installing the CarrierWave ODU There are three options for mounting the CarrierWave ODU Antenna mast Pole Building Each site must be assessed for the mounting method, location, and height.

Tilt Bracket CarrierWave Digital Radio MK-MAN-01 3-20 Installation Figure 3-11. CarrierWave ODU with Mounted Tilt Bracket 3.6.3 Routing the ODU/IDU Interconnect Cable 1. Select where the cable will enter the building from outside. 2. Determine the length of cable required. Allow three extra feet on each end to allow for strain relief, as well as any bends and turns. 3. Route the cable. The ODU and IDU are equipped with N-type female connectors at their interconnecting ports. A length of coaxial cable (such as Times Microwave Systems LMR-400, LMR-300 or LMR-200) fitted with two N-type male connectors is required to connect the ODU to the IDU. This cable assembly may be supplied in fixed lengths with the digital radio. Bulk coaxial cable of equivalent specification may also be used, with terminating connectors applied during cable installation. Based on an evaluation of the cable routing path, pull the ODU/IDU Interconnect cable from one unit to the other, utilizing cable trays, ducts, or conduit as required. Take care that the ODU/IDU Interconnect cable is not kinked or damaged in any way during installation. Be sure to protect the N-type connectors from stress, damage and contamination during installation (do not pull the cable by the connectors). If multiple ODU/IDU Interconnect cables are to be installed along the same route, the cables should all be pulled at one time. Be sure the installed cable does not have any bends that exceed the specified cable bend radius. The ODU/IDU Interconnect cable should be adequately supported on horizontal runs and should be restrained by hangers or ties on vertical runs to reduce stress on the cable. Outside the building, support and restrain the cable as required by routing and environmental conditions (wind, ice). The CarrierWave ODU/IDU and interconnection must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires that the ODU, any mounting pole or mast and any exposed interconnect cable be grounded on the outside of the structure. The IDU must be grounded to a rack or structure ground that also has direct path to earth ground. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-21 The ODU must be directly connected to a ground rod or equivalent earth ground. The ODU/IDU interconnect cable should also be grounded at the ODU, where the cable enters the structure and at intermediate points if the exposed cable run is long (typically at intervals of 100 ft), with the cable manufacturers grounding kits. Lightning protection devices used with the interconnect cable must be appropriate for the transmission of the interconnect signals (DC to 2.4 GHz). Provide a sufficient but not excessive length of cable at each end to allow easy connection to the ODU and IDU without stress or tension on the cable. Excessive cable length, especially outdoors, should be avoided to minimize signal attenuation and provide a more robust and reliable installation. If installing using bulk coaxial cable, terminate the ODU/IDU Interconnect cable at each end with an N-type male connector appropriate for the cable type. Use of connectors, is recommended. termination procedures specified by the cable manufacturer tools and Once the cable has been installed but before connection has been made to either unit, a simple DC continuity test should be made to verify the integrity of the installed cable. A DC continuity tester or digital multimeter may be used verify a lack of DC continuity between the cable center conductor and outer conductor, with the opposite end of the cable unconnected. With a temporary test lead or shorting adapter connected to one end of the cable, DC continuity should be verified between the center and outer conductors at the opposite end. 3.6.3.1 Installing the ODU/IDU Interconnect Cable 1. Screw on the ODU/IDU Interconnect cable with N-type connector. Figure 3-12. N-type Connector Location Underside of CarrierWave ODU 2. Insert the N-type connector into the receptacle located underneath the ODU. Make sure that the connector tab engages the slot in the receptacle. 3. Slide the grommet up the cable and press it into the bottom of the ODU. 3.6.4 Grounding the System The CarrierWave IDU/ODU System must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires:

1. Grounding all the ODUs as shown in Figure 3-13. CarrierWave Digital Radio MK-MAN-01 3-22 Installation 2. Grounding the IDU to the rack. 3.6.4.1 Grounding the ODU 1. Place the grounding rod so as to allow for the shortest possible path from the grounding cable to the ODU. 2. Drive the grounding rod into the ground at least eight inches from the ground surface. 3. Attach a grounding clamp to the grounding rod. You will use this clamp to attach grounding wires for both the ODU and indoor junction box, reference Figure 3-13. Figure 3-13. Ground Connections to ODU 4. Connect a ground lug to one end of the grounding wire. 5. Remove one of the lower mounting screws of the mounting pole. Insert a screw through the grounding lug terminal and re-install it to the mounting pole. 6. Attach the grounding wire to the clamp on the grounding rod, reference Figure 3-14. If necessary, use wire staples to secure the grounding wire to the outside wall. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 3-23 Figure 3-14. Mounting Pole with Ground Lug 7. Install a grounding wire from the junction box to the grounding rod. 3.6.4.2 Grounding the IDU 1. Remove the nut and ring lug terminal from the IDU Chassis GND stud. 2. The provided ring lug crimp terminal is intended to be used with 18 AWG wire (provided by the customer). The IDU should be able to be connected to a system or building electrical ground point (rack ground or power third-wire ground) with a cable of 36 or less. 3. Crimp the ring lug terminal to one end of the wire to be used as the IDU ground wire. Connect the opposite end of the IDU ground wire to the local source of ground in an appropriate manner. 4. Place the ring lug of the IDU ground cable on the IDU Chassis GND stud. 5. Place the nut on the IDU Chassis GND stud and tighten appropriately. 3.7 Configuration of the CarrierWave Digital Radio Configuration of the CarrierWave Digital Radio IDU does not require a connection to the ODU.

>CarrierComm->vX-XX->IC menu (or iConductorTM software. 3.7.2.2 Connecting the IDU to the PC and Power Source Perform the following steps to ensure the IDU is powered up and connected to you PC:

1. To connect to the IDU DC power connector (located on the IDU rear panel), an IDU power cable is required. A mating power cable connector (Phoenix Contact P/N 17 86 83 1) is provided with the CarrierWave IDU for construction of this cable. This connector has screw clamp terminals that accommodate 24 AWG to 12 AWG wire. The recommended wire size for construction of power cables under 10 feet in length, supplying 48 V dc, is 18 AWG. The opposite end of the IDU power cable should have a termination appropriate for the power supply being used. The IDU power cable should be of sufficient length to avoid tension in the cable and provide a service loop for connection, but not be of excessive length. Stranded wire should be used over a solid conductor to reduce tension on the IDU DC Power connector. Using the supplied power cable connector, pin 2 (labeled -V) should be connected to the power supply terminal supplying 48 V dc, while pin 1 (labeled RET) should be connected to the power supply return. Refer to Figure 3-15. Note that pin 1 (RET) of the IDU DC Power connector is connected to the IDU chassis ground internal to the IDU. Use of a power supply with an inappropriate ground reference may cause damage to the IDU and / or the supply. 2. Connect the IDU power cable to the 48 V dc power supply, and place the voltmeter probes on the unconnected IDU end of the power cable, with the positive voltmeter probe on pin 2

(-V) of the cable connector and the negative probe on pin 1(RET). The connector screw terminal screw heads may be used as convenient monitor points. Refer to Figure 3-15. 3. Turn on the 48 V dc supply. Verify that the digital voltmeter reads between 44 V dc and 52 V dc when monitoring the cable points specified above. Adjust the power supply output voltage and/or change the connections at the power supply to achieve this reading. 4. With the negative voltmeter probe still on pin 1 (RET) of the power cable connector (and the power supply still on), press the positive voltmeter probe to the IDU chassis and verify a potential of zero volts between the IDU chassis and cable pin 1 (RET). If the measured potential is not zero, the power supply may be grounded incorrectly and should not be used in this condition with an IDU. Note that this measurement assumes that the IDU is installed and properly grounded. If this is not the case, the same measurement can be made between cable pin 1 (RET) and a convenient ground (such as an ac outlet third-wire ground). 5. Turn the 48 V dc supply off. 6. Plug the IDU power cable into the IDU rear panel DC Power connector (DC Input). Place the voltmeter probes on the cable connector screw terminal screw heads as per step 2 above. Refer to Figure 3-15. Note that the CarrierWave Digital Radio IDU does not have a power on/off switch. When DC power is connected, the digital radio powers up and is operational. There can be up to 200 mW of RF power present at the antenna port. The antenna should be directed safely when power is applied. 7. Turn on the 48 V dc power supply, and verify that the reading on the digital voltmeter is as specified in step 3 above. CarrierWave Digital Radio MK-MAN-01 3-26 8. Turn the 48 V dc supply off. Installation 9. Connect the IDU to the laptop computer, using the Cat-5 Ethernet crossover cable or connect the IDU to a computer network, using a normal Cat-5 Ethernet cable. Connect the Ethernet cable to OAMP 10/100BaseTX Ch1 connector on the IDU rear panel. Refer to Figure 3-16 for the IDU rear panel connections. 2 1 Figure 3-15.

The unit has 6 buttons for user input: Up, Down, Left, Right, Enter, and Escape. MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 4-5 There are two basic screen types used to build the interface application, Text Screens and Menu Screens. 4.4.1 Text Screens Text screens are used to display information to the user, but do not allow for any user input. 4.4.1.1 Display When the screen is displayed on the LCD panel the first four lines are visible, and if there are more than four lines in the screen, a plus (+) sign is displayed in the lower right hand corner of the display. 4.4.1.2 Buttons The Enter, Left, and Right buttons do nothing on a text screen. If the screen contains more than four lines the Up and Down buttons scroll up and down one line at a time. The Escape button navigates to the previously viewed screen. 4.4.1.3 Example Figure 4-3. OA&M Parameter Display 4.4.2 Menu Screen Menu screens are used to navigate around the system and for data entry. Each menu is composed of menu elements that serve different purposes. There are currently four menu element types, Text, Command, Selection, and Edit. 4.4.2.1 Display Each line is one menu element as described above. Normally the first line is a Text element, which is the title of the menu. When the menu is scrolled, the title remains fixed while the bottom three lines scroll. The plus (+) sign is displayed in the bottom right corner to indicate that there are more lines below just as in the Text Screen. A menu screen has a cursor that is displayed as an asterisk (*) in the left most character position and indicates the active element. When the screen is entered the cursor is on the second line

(first line below the title). CarrierWave Digital Radio MK-MAN-01 4-6 Front Panel Operation The display characteristics of the different menu element types differ slightly. The text element is centered horizontally in the display. The command element is also text but is left justified with room for the cursor. Both the selection and edit types have a label that is left justified, then a colon, then the data field. 4.4.2.2 Buttons All buttons are active on a menu screen, depending on the type of the active element. The Up and Down buttons move the cursor up and down, changing the active element. If the cursor is on the bottom row, there are more rows below, and the Down button is pressed, the bottom three lines scroll upward exposing the next line. The Up button has the same behavior in the opposite direction. The Escape button will always navigate to the previously viewed screen. The Enter, Left, Right, Up, and Down button behaviors differ slightly depending on the type of the active menu element and will be described below. If the active element is a command element, the Left and Right buttons have no effect and the Up and Down buttons will behave as detailed above. The Enter button executes the command associated with that element. The command can be a navigation command that takes the user to another screen, or action command that performs an action. If the active element is a selection element, the Left and Right buttons scroll through a list of valid values, displaying the currently selected value on the right side of the active line on the screen. The Up and Down buttons still have their normal behavior of moving the cursor up or down to a different element. The Enter button will execute a command passing the selected value. If the active element is an edit element, the Up and Down buttons still have their normal behavior until the Right button is pressed. The Left and Right buttons move a blinking cursor within the data field to facilitate editing that field. Once the blinking cursor is in the data field, the Up and Down buttons scroll through a list of valid characters for that field, allowing limited data entry. If the blinking cursor is on the first character of the data field and the Left button is pressed, the blinking cursor disappears and the Up and Down buttons behave normally again. As with the selection element, the Enter button executes a command and passes the data field to the command. 4.4.2.3 Examples Figure 4-4. Menu Screen with Command elements MK-MAN-01 CarrierWave Digital Radio User Reference and Installation Manual 4-7 Figure 4-5. Menu Screen with one Command and two Edit elements 4.5 Menu Tree Structure This section shows the hierarchy of the menu system. In general, <ENTER> will take you to the next screen from a menu choice, <UP> or <DOWN> will scroll through screens within a menu choice, and <ESC> will take you back up one menu level.
