ADCP-75-158 • Issue 1 • July 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 GFCI 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 bottom of the RU cabinet to permit air exchange for cooling. Air enters the cabinet through an opening in the front/bottom side of the cabinet A Filter removes 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/bottom 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.

Select the first file to download and click on the OK button. 5. Click on the HOST Load button (see Figure 4-3) to start the download. 6. Repeat steps 4 and 5 for each file that requires downloading. 7. Repeat steps 2 through 5 for the REMOTE. 2.3Determine Forward Path Input Signal Level The level of the composite RF input signal at the FORWARD RF IN port at the HU will vary depending on the type of BTS, the cable loss, the number of channels present, and the required forward path composite power. If maximum composite RF output is required, the signal level of the composite forward path RF signal at the HU forward path input must be adjusted to fall within a range of –9 to –40 dBm. If the signal level is not within this range, it must be adjusted to fall within this range through the use of an external attenuator capable of handling the BTS forward path output power. If using the Conditioning Panel or Duplexing Panel, refer to the Digivance 800 and 1900 MHz Interface Panels User Manual (ADCP-75-147) for the procedures for measuring and adjusting the input RF signal level at the HU. If connecting a single HU to a single BTS, use the following procedure to measure and adjust the input RF signal level at the HU: 1. Connect a spectrum analyzer or power meter to the forward path output port of the BTS. The required signal levels and test points are shown in Figure 4-5. 2. If using a spectrum analyzer, proceed to step 3. If using a power meter, measure the composite signal power from the BTS and then proceed to step 5. 3. Measure the RF level of a single carrier, such as the control channel, in dBm. Make sure the resolution bandwidth of the spectrum analyzer is 30 kHz. Maximum power in any channel should not exceed 5W (+37 dB). Note: Check the input rating of the test equipment and the output rating of the BTS. To avoid burning out the spectrum analyzer or power meter, it may be necessary to insert a 30 dB 100W (or similar) attenuator between the BTS and test equipment. ADCP-75-158 • Issue 1 • July 2003 • Section 4: Operation Page 4-8 © 2003, ADC Telecommunications, Inc. 4. Calculate the total composite signal power from the BTS using the following formula: P tot = P c + 10Log N – (see Note) Where, P tot is the total composite power in dBm P c is the power per carrier in dBm as measured in step 3, and N is the total number of channels. 5. Determine the total cable loss that is imposed by the forward path coaxial cable that links the BTS to the HU and also any insertion loss imposed by splitters or combiners. 6. Subtract the total cable loss and any insertion losses from the total composite power calculated in step 4. 7. Subtract –25 (midpoint of the required range) from the value determined in step 6. The difference (which should be positive) equals the value of the external attenuator that is required to reduce the forward path signal level to fall within the required range. The following formula outlines the required calculations for steps 6 and 7: P tot – (Cable and insertion loss) – (–25) = Value of external attenuator required 8. Select an attenuator that is as close to the value calculated in step 7 as possible. Select a value that will adjust the signal level of the composite input signal to fall within the specified range. 9. Install the external attenuator in the coaxial cable that is connected to the FORWARD RF IN port at the HU. 10. Subtract the value of the external attenuator used in step 9 from the total composite signal power (P tot ) and record the result. This value will be required when setting the attenuation of the HU’s internal forward attenuator. Note: If calculating the composite power for a CDMA system, reduce the initial result by 16.23 dB. Note: If the input signal level is already within the required range of –9 to –40 dBm, then no external attenuator is required. Caution: The Host Unit can be damaged if it is overdriven by the BTS. Always install an external protective attenuator at the Host Unit FORWARD RF IN port if the forward path composite input signal level is greater than –9 dBm.
