Test Equipment Setup
Follow the procedure in Table 3-48 to set up test equipment:
NOTE
All alarm tests are performed using TX antenna 1
Table 3-48: Test Equipment Setup for Redundancy/Alarm Tests
Step Action
1 Interface the LMF computer to the BTS LAN A connector on the BTS frame (refer to Table 3-2,
page 3-6).
2 Login to the BTS.
3 Set up test equipment for TX Calibration at TXOUT1 (see Figure 3-12).
NOTE
If site is not equipped for redundancy, remove all GLI and BBX boards installed in any redundant
slot positions at this time.
4 Display the alarm monitor by selecting Util>Alarm Monitor.
5 Unequip all customer defined AMR alarms reported via the AMR Alarm connector (A & B) by
clicking on MGLI, then selecting Device>Set Alarm Relays>Unequipped.
NOTE
During configuration of MGLI alarm reporting, spurious alarms may report. Allow the BTS to
stabilize for 10 seconds. If any alarms are actively being reported after the BTS has stabilized,
determine the cause before proceeding further.
Power Supply Redundancy
Follow the steps in Table 3-49 to verify redundancy of the power supply
modules. Alarms reported by the master GLI (displayed via the alarm
monitor) are also verified.
Table 3-49: Power Supply/Converter Redundancy (BTS Frame)
Step Action
1 Select the MGLI (highlight) and from the pulldown menu select:
Device>BBX/MAWI>Set Redundant Sector>Carrier-#-1-1
Device>BBX/MAWI>Set Pilot Only>Carrier-#-1-1
Device>BBX/MAWI>Set Pilot Gain>Carrier-#-1-1 and Pilot Gain = 262
2 Select (highlight) BBX-1 and from the pulldown menu select Device>BBX/MAWI>Key.
3 Set XCVR gain to 40 and enter the correct XCVR channel number.
4 Remove PS-1 from the power distribution shelf (see Figure 3-22).
- Observe that an alarm message is reported via the MGLI as displayed on the alarm monitor.
- Verify no other modules went OOS.
5 Re-install PS-1.
Observe the alarm clears on the alarm monitor.
6 Repeat steps 4 and 5 for PS-2 and PS-3.
