ADCP-75-158 • Preliminary Issue A • June 2003 • Section 2: Description Page 2-10 © 2003, ADC Telecommunications, Inc. 3.6Antenna Cable Connection An N-type female connector is provided on the exterior bottom side of the RU cabinet for connecting the antenna coaxial cable. The exterior N-type connector is on the surge side of a lightning protector that is mounted within the enclosure. On the inside of the enclosure, the protected side of the lightning protector is also equipped with an N-type female connector. A coaxial jumper cable (included with the enclosure) is used for connecting the protected side of the lightning protector to the ANTENNA port on the STM. 3.7AC Power Wiring and Grounding The RU outdoor cabinet is equipped with a stub cable for the AC power connections. The AC power cable provides three wire leads (Load, Neutral, and Ground) that must be connected to a 120 or 240 VAC power source. The AC power cable exits the cabinet though a 3/4-inch NPT threaded hole located on the bottom of the cabinet. The threaded hole accepts a standard 3/4- inch AC conduit fitting. A 3/4-inch to 1/2-inch reducer is also included if 1/2-inch conduit is preferred over 3/4-inch conduit. From the exit point in the bottom of the cabinet, the AC power cable must be routed through conduit to an external AC junction box (not provided) where it can be connected to the AC power wiring. The junction box should be located within two feet of the cabinet and should be equipped with a 120 VAC outlet for powering test equipment and/or power tools. If AC power spikes are likely to occur, the junction box should also include a surge protector to protect the equipment from damage. Three wire nuts are included with the cabinet for completing the AC power wiring connections. The junction box wiring should be connected to the AC power source through a 20 Amp breaker box (not provided). All AC power wiring should be run within conduit. A grounding lug is provided on the underside of the enclosure for connecting a separate grounding wire directly to the cabinet. 3.8Ventilation Vent openings are provided in the door, on the bottom, and on the rear side of the RU cabinet to permit air exchange for cooling. Air enters the cabinet through the openings in the door and bottom. Filters remove dirt particles so that only clean air enters the enclosure. Both the STM and LPA have cooling fans. The STM has a rear mounted fan that pulls air through the module and exhausts it toward the rear of the enclosure. The LPA has a fan on the front that draws air into the module and exhausts it toward the rear of the enclosure. The heated air exits through an opening in the rear side of the enclosure. 3.9User Interface The RU cabinet user interface consists of the various connectors, fittings, mounting slots, and switches that are provided on both the interior and exterior of the enclosure. The user interface points are indicated in Figure 2-4 and described in Ta b l e 2 - 2.

ADCP-75-158 • Preliminary Issue A • June 2003 • Section 2: Description Page 2-27 © 2003, ADC Telecommunications, Inc. The NOC/NEM interface is a command line interface that is presented at an NOC terminal. The NOC/NEM interface is used for remote control and monitoring operations. The NOC/NEM interface consists of ASCII text strings that are input as standard SET or GET commands which are followed by the action or information required. A text string response is received from the specified system or systems to confirm the requested action or to report the requested information. Examples of several typical NOC-NEM interface commands and the responses received are shown in Figure 2-19. The NOC/NEM interface requires only a VT100 terminal/ emulator or a PC-type computer that is loaded with a communication software such as Procomm Plus. While primarily intended for use at the NOC, the NOC/NEM interface commands may also be input from the EMS computer. Figure 2-19.

ADCP-75-158 • Preliminary Issue A • June 2003 • Section 3: Host Unit Installation Page 3-8 © 2003, ADC Telecommunications, Inc. 5CHASSIS GROUND CONNECTION A stud is provided on the rear side of the chassis for connecting a grounding wire to the chassis. Use the following procedure to connect the grounding wire to the chassis and to route the grounding wire to an approved earth ground source. 1. Obtain a length of #18 AWG (1.00 mm) insulated stranded copper wire for use as a chassis grounding wire. 2. Terminate one end of the wire with a ring terminal. 3. Locate the chassis ground stud at the rear of the HU as shown in Figure 3-7. Figure 3-7. Chassis Ground Stud 4. Attach the ring end of the wire to the chassis ground stud (see Figure 3-7). 5. Route the free end of the chassis grounding wire to an approved (per local code or practice) earth ground source. 6. Cut the chassis grounding wire to length and connect it to the approved ground source as required by local code or practice. 6 COAXIAL CABLE CONNECTIONS The RF interface between the HU and the BTS is supported through two N-type female connectors mounted on the HU front panel. One connector provides the coaxial cable connection for the forward path (downlink) signal and the other connector provides the coaxial cable connection for the reverse path (uplink) signal. In most installations, it is usually necessary to insert some attenuation in the forward path link between the HU and the BTS. A signal level that is greater than –9 dBm will overdrive and Note: Be sure to maintain reliable grounding. Pay particular attention to ground source connections. 16169-A FCC ID: F8I-DLC1902A ADCP-75-158 • Preliminary Issue A • June 2003 • Section 3: Host Unit Installation Page 3-9 © 2003, ADC Telecommunications, Inc. possibly damage the HU receiver. Refer to Section 4, Subsection 2.3, before completing the forward path connection at the BTS. If the Conditioning Panel or Duplexing Panel is required, refer to the Digivance 800 and 1900 MHz Interface Panels User Manual (ADCP-75-147) for the installation procedures. The HU should be mounted as close as possible to the BTS to minimize cable losses. Use the following procedure to route and connect the forward and reverse path coaxial cables to the HU: 1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial communications cable (RG-400 or equivalent) for all coaxial connections. 2. Route the forward and reverse path coaxial cables between the HU and the BTS interface (per system design plan) and cut to the required length. Allow sufficient slack for dressing and organizing cables at the HU and for installing an external attenuator in the forward path link. 3. Terminate each cable with an N-type male connector following the connector supplier’s recommendations. 4. Connect the forward path cable to the FORWARD RF IN connector on the HU front panel as shown in Figure 3-8. Figure 3-8. Forward and Reverse Path Coaxial Cable Connections 5. Connect the reverse path cable to the REVERSE RF OUT connector on the HU front panel (see Figure 3-8). 6. Dress and secure cables at the HU. 7. Complete all remaining coaxial connections as specified in the system design plan. Note: Do not connect the forward path cable at the BTS until the composite forward path RF signal level is measured and the amount of attenuation required is determined. 18655-A TYPE-N MALE CONNECTOR FORWARD RF IN CONNECTOR (FORWARD PATH) REVERSE RF OUT CONNECTOR (REVERSE PATH) ADCP-75-158 • Preliminary Issue A • June 2003 • Section 3: Host Unit Installation Page 3-10 © 2003, ADC Telecommunications, Inc. 7 OPTICAL CONNECTIONS The optical interface between the HU and the RU is supported by two optical ports. Each optical port consists of an SC optical adapter which is mounted on the HU front panel. Port 1 provides the optical fiber connection for the forward path (downlink) signal. Port 2 provides the optical fiber connection for the reverse path (uplink) signal. The optical connections are dependent on whether or not a WDM host module (accessory) or CWDM host module (accessory) is installed. If the installation does not include either a WDM or CWDM module, proceed to Section 7.1 for the optical connections procedure. If the installation includes a WDM module, proceed to Section 7.2 for the optical connections procedure. If the installation includes a CWDM module, refer to the Digivance System Coarse Wavelength Division Multiplexer User Manual (ADCP-75-142) for the optical connection procedure. 7.1Optical Connections Without WDM or CWDM system Use the following procedure to connect the optical fibers when a WDM or CWDM host module is not installed with the HU: 1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiber distribution panel. 2. Designate one of the patch cords as the forward path link and the other as the reverse path link and attach an identification label or tag next to each connector. 3. Remove the dust caps from the HU optical ports and from the patch cord connectors that will be connected to the HU. 4. Clean each patch cord connector (follow patch cord supplier’s recommendations). 5. Insert the connector into the appropriate optical port as shown in Figure 3-9. 6. Route the patch cords from the HU to the fiber distribution panel. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transmitter of any unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transmitter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the connector. Note: To protect the optical receivers, insert a 15 dB attenua…

If a delay adjustment is required per the system design plan, enter the Host Fwd Delay and Host Rev Delay values. By default, the delay values are set to 0. Refer to Section 2.9 for details. 25. If a separate laptop computer loaded with the EMS software was used to initially configure the system, disconnect the laptop computer from the SERVICE connector on the HU front panel. 26. Reconnect the external alarm system or notify the alarm system provider that the turn-up process has been completed. Note: For continuous monitoring of alarms, each HU and RU pair must remain permanently connected to a PC-type desktop computer loaded with the EMS software. When two or more systems are connected together through the CAN interface, only one EMS computer is required to manage the networked HU and RU systems. The EMS computer may be connected to the SERVICE port on any one of the HUs in the network.
