This process assumes that the various units have been installed in accordance with the system design plan. 1.1 Tools and Materials The following tools and materials are required in order to complete the procedures in this section: • Portable spectrum analyzer or RF power meter • AC/DC voltmeter • External attenuators (if specified in system design plan) • PC-type computer with Digivance Element Management System (EMS) software installed • Straight-through RS-232 DB-9 interface cable (ADC part # 1192835) • Handset • Pencil or pen • Writing pad Page 4-1 © 2002, ADC Telecommunications, Inc. ADCP-75-134 • Issue A • April 2002 • Section 4: Operation 1.2 Readiness Check Before starting the turn-up process, inspect the complete LRCS system to verify that all components of the system are ready to be powered-up. This will ensure that no units of the system will be damaged during turn-up and that all existing systems will continue to function properly. 1.2.1 Host Unit Installation Checks Complete the following checks at the HU prior to starting the turn-up process: 1. Verify that the ON/OFF switch on the HU is in the OFF position (press O). 2. At the fuse panel, install a 3 Amp GMT fuse in the circuit that supplies DC power to the HU. 3. Using a DC voltmeter, verify that the DC voltage level at the HU power terminals is between ± 24 or ± 48 Vdc (can be either polarity). 4. Verify that all electrical and optical connections have been completed and that all optical fibers, coaxial cables, and wires are properly routed and secured. 1.2.2 Remote Unit Installation Checks Complete the following checks at the RU prior to starting the turn-up process: 1. Verify that the ON/OFF switch on the STM is in the OFF position (press O). 2. Verify that the RF ON/OF switch on the LPA in the OFF position. 3. At the AC breaker box, close the circuit breaker for the circuit that supplies AC power to the RU. 4. Using an AC voltmeter, verify that the AC voltage level at the AC outlet is between 110 and 120 Vac (for 120 Vac powered systems) or between 220 and 240 Vac (for 240 Vac powered systems). 5. Verify that all electrical and optical connections have been completed and that all optical fibers, coaxial cables, and wires are properly routed and secured. TURN-UP SYSTEM AND VERIFY OPERATION The process of turning-up the system and verifying operation involves powering up the various system components, verifying that the LED indicators show normal operation, setting the site number and name, adjusting the RF signal levels, and adjusting the path delay. Page 4-2 © 2002, ADC Telecommunications, Inc. ADCP-75-134 • Issue A • April 2002 • Section 4: Operation 2.1 Turn-Up Procedure Use the following procedure to turn-up the system: 1. Temporarily disconnect the external alarm system or notify the alarm system provider that testing is in progress. 2. If turning-up multiple HU and RU systems that have not been configured for operation before, temporarily disconnect the CAN cables from the NET IN and NET OUT ports of each HU. Note: By default, all HU’s and RU’s are programmed with the same site number and name. This can cause problems for the Digivance EMS if multiple HU’s with the same site number and site name are networked together through the CAN interface. It is therefore advisable to temporarily disconnect the CAN interface cables from the HU until a unique site number and name can be entered for each HU and its corresponding RU. 3. Determine if the forward path input signal level at the Host Unit FORWARD RF IN port is between –20 and –40 dBm and adjust level if required. Refer to Section 2.3 for the calculation and adjustment procedure. 4. Connect the EMS computer (if not already connected) to the SERVICE connector on the HU or STM front panel. If necessary, a separate laptop computer loaded with the EMS software can be temporarily connected and used to initially configure the system. 5. Place the ON/OFF switch on the HU in the ON position (press I). 6. Place the ON/OFF switch on the STM in the ON position (press I). 7. Wait 6 to 8 seconds for the HU and the RU modules to initialize and then observe the LED indicators on the HU, STM and LPA. Refer to Section 5 for the troubleshooting procedures if the indicators do not respond as specified.

Click on the HOST RF tab (see Figure 4-2). The HOST RF display will open within the main window. 23. Enter the Host Rev Att (Reverse Attenuation), and Host Div Rev Att (Diversity Reverse Attenuation) values. This sets the reverse output RF signal levels at the HU. Refer to Section 2.8 for details. 24. If a delay adjustment is required per the system design plan, enter the Host Fwd Delay, Host Rev Delay, and Host Div 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. Note: Each HU and RU pair will generally 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 power on any one of the HUs in the network. Page 4-5 © 2002, ADC Telecommunications, Inc. ADCP-75-134 • Issue A • April 2002 • Section 4: Operation 26. Reconnect the external alarm system or notify the alarm system provider that the turn-up process has been completed. 2.2 Download HU and RU System Software The HU’s and RU’s may require a system software download to make them operational.

Select Control Program File Window Page 4-6 © 2002, ADC Telecommunications, Inc. ADCP-75-134 • Issue A • April 2002 • Section 4: Operation 3. Select the required file to download and click on the OK button. 4. Click on the HOST Load button (see Figure 4-3) to start the download. 5. Repeat steps 2 through 4 for the REMOTE. 2.3 Determine Baseline Forward Path Input Signal Level The level of the composite RF output signal at the FORWARD RF IN port at the HU will vary depending on the type of BTS, the cable loss, and the number of channels present. To interface with the HU, the signal level of the composite forward path RF signal must be adjusted to fall within a range of –20 to –40 dBm. If the signal level is not within this range, it must be adjusted to fall within this level through the use of an external attenuator. 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 at the EBTS. The required signal levels and test points are shown in Figure 4-5. 2. Measure the RF level of a single carrier, such as the control channel, in dBm. Make sure the resolution bandwidth of the spectrum analyzer or power meter is narrow enough to measure the power of the single 30 kHz channel only. 3. Verify that all carriers are coming in at equal power at bandwidth and adjust to the same level if necessary. 4. Calculate the total composite signal power from the EBTS using the following formula: Ptot = Pc + 10Log N Where, Ptot is the total composite power in dBm Pc is the power per carrier in dBm as measured in step 2, 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 EBTS 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 –30 (the 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: Ptot – (Cable and insertion loss) – (–30) = Value of external attenuator required Note: If the input signal level is already within the required range of –20 to –40 dBm, then no external attenuator is required.
