BTS Configuration – continued Table 7-5: Create a HyperTerminal Connection Step Action NOTE For CDMA LMF computer configurations where COM1 is used by another interface such as test equipment and a physical port is available for COM2, select COM2 in the following step to prevent conflicts. 4 From the Connect using: pick list in the Connect To box displayed, select Direct to Com 1 or Direct to Com 2 for the RS–232 connection port, and click OK.
PAGE 85
BTS Configuration – continued Establishing an MMI Communication Session For those procedures which require MMI communication between the CDMA LMF and the BTS, follow the procedures in Table 7-6 to initiate the communication session. NOTE If an LMF session is in progress, logout of the LMF prior to establishing an MMI communication session. Refer to steps 1 and 2 of the “Remove LMF” procedure in Table 7-38. Table 7-6: Establishing MMI Communication Step Action 1 Connect the CDMA LMF computer to the BTS.
PAGE 86
BTS Configuration – continued It is imperative that the customer frequency be programmed into this database. Failure to do so may result in the RF interference to other RF–emitting devices in the local area whenever the site is powered up. Table 7-7: Updating Default Channel Setting to Customer Operating Channel Step Action 1 Connect the LMF computer terminal to the MMI/LMF connector. Refer to Figure 7-7. 2 If you have not already done so, logout of the BTS and exit the LMF.
PAGE 87
BTS Configuration – continued NOTE The HSO must be installed with GPS tracking for at least 24 hours before the HSO can provide 24 hours of backup for CDMA system time synchronization. BTS The BTS uses a Digital Phase Locked Loop (DPLL) to track the RGPS and/or HSO and generate a 19.6608 MHz CDMA timing reference. This timing reference, in conjunction with Time Of Day information provided by the RGPS, allows the BTS to synchronize to CDMA system time.

BTS Configuration – continued Table 7-8: Verify BTS Sync Mode Step Action 1 If an MMI session was established, proceed to step 6. If no MMI session is running, proceed to step 2. 2 Connect the MMI/LMF. 3 Open an MMI Communication session. 4 Simulate an LMF connection by issuing the sndtype 0xa178 command. 5 Verify that the BTS is in OOS_RAM status by issuing the status command. 6 Observe the condition of the External indicator.

ATP Overview Overview The purpose of this procedure is to outline the optimization and ATP procedure for a unit configured as a Frequency Hopping Pilot Beacon (FHPB). This feature offers the ability to configure a standard SC300 MicroCell or PicoCell as a frequency hopping pilot beacon. The FHPB serves the same role in initiating mobile–assisted hard handoff as a conventional pilot beacon. However, the FHPB serves tp to six carriers in a time division multiplexed fashion.
PAGE 138
Create CAL File Overview Use this procedure to create a CAL file for the Calibration audit. You must do this procedure before the RF path audit. Create CAL File The Create CAL File function gets the BLO data from the MAWI and creates/updates the CAL file for the BTS. If a CAL file does not exist, a new one is created. If a CAL file already exists, it is updated.
PAGE 139
Create CAL File – continued Procedure Use the following procedure in Table 8-1 to create a CAL file. Table 8-1: Create CAL File Step Action 1 Log on to the BTS if you have not already done so. 2 Select the MAWI. 3 Click on the Device menu. 4 Click on the Create Cal File menu item. The status report window displays the results of the action. 5 Click OK. NOTE The bts–#.cal is located in the wlmf\cdma\bts–# folder (where # is the number of the BTS).
PAGE 140
RF Path Audit Test Equipment Setup The BTS RF path is calibrated in the factory. There is no need to calibrate during installation. IMPORTANT * All tests are measured with respect to the Antenna output connector. Additional losses must be compensated for. RF calibration does not take the following into consideration: – Antenna feedline losses. – Antenna gain. Transmit (TX) Audit Prerequisites You must complete the following steps before you do the TX RF path audit: 1.
PAGE 141
RF Path Audit – continued Table 8-2: RF Path Audit Step Action 1 Configure test equipment for TX path calibration according to NO TAG. 2 Select the MAWI.

The test results will be displayed in the status report window. 6 Click OK to close the status report widow.
PAGE 142
Acceptance Tests TX Test Objective The following tests will verify the TX antenna path. Output power control will also be verified. All tests will be performed using the power meter and communication test set. Measurements will be via the Antenna A (Picocell) and Antenna B (Microcell) connectors. NOTE You must remove the antenna cables before you perform the ATP. The BTS is keyed up to generate a CDMA carrier at 31 dBm for MicroCell and 17 dBm for PicoCell.
PAGE 143
Acceptance Tests – continued Code domain power noise, pilot power, and total power You will verify that the code domain noise floor of all unused Walsh codes within the CDMA spectrum measures < –27 dB (with respect to total power). Pilot power will be verified to measure –7.04 dB +/–0.5 dB (with respect to standard test patterns). Total power will be verified to measure +2/–4 dB (with respect to CDF specific file parameters).
PAGE 144
TX Acceptance Tests TX ATP Test Refer to Table 8-3 to perform a TX ATP test. This procedure assumes that the site specific CDF file is in the wlmf\cdma\bts–# folder. The ALL TX list performs the following ATP tests: 1. TX Mask 2. Rho 3. Pilot Time Offset 4.

Shut Down & Restoring BTS Signaling Overview The FRU procedures require the shut down of BTS signalling functions. Accessing the OMCR CLI window The commands to manipulate the BTS in the following replacement procedure must be entered via UNO or OMCR (Operations and Maintenance Center – Radio). IMPORTANT * Should there be any issues which affect CLI operations or the UNO/OMCR, this replacement procedure cannot be performed.
PAGE 157
Shut Down & Restore BTS Signaling – continued IMPORTANT * The EDIT SECTOR REDIRECT command does NOT affect calls in progress and will NOT move these calls to another sector/carrier. The command only prevents future calls from being originated on the targeted sector/carrier. If active call processing is still taking place in the target sector/carrier, it is advisable to wait for any active calls to terminate prior to disabling the sector.

Outdoor Grounding Guidelines Summary A General This is a summary of the outdoor grounding guidelines. Outdoor installations should be based on this summary and site specific documentation. Motorola publication 68P81150E62 should also be followed to ground an antenna tower. This guideline assumes that auxiliary equipment is co–located at the installation site. All of the equipment referenced may not be present at every site.

A Outdoor Grounding Guidelines Summary – continued MGP at the antenna access point. The signal (center) conductor must be protected by a lightning arrestor. The lightning arrestor connects to the MGP at the same point as the ground conductor (shield) of the antenna cable. Chassis The ground stud of the BTS chassis connects to the MGP. T1 Span Lines The BTS can connect to two T1 span lines. For many applications the T1 cable is derived from an optical fiber interconnect.
