SCt300 BTS Hardware Installation, ATP and FRU Procedures

PRELIMINARY

Table 7-30: TX Test Using Backup Synchronization

Step Action

13 If logged into the BTS with the LMF, then logout.

14 Open an MMI Communication session.

15 Verify that the BTS is in OOS_RAM status by entering the status command.

16 Simulate an LMF connection by entering the sndtype 0xa178 command.

17 Disable the simulation of the GPS losing tracked satellites by entering the gps_rx_debug

nosats off command at the MMI prompt.

NOTE

The gps_rx_debug command simulates the “No Satellites Tracked” condition. In reality, the

receiver is tracking satellites. However, the software is masking that information. Be sure to turn

off the “No Satellites” condition after completing this test.

18 Follow the procedure in Table 7-9 (Synchronization Verification) to insure the BTS is tracking the

RGPS.

RX ATP Test

Refer to Table 7-31 to perform an RX ATP test. This procedure assumes

that the site specific CDF file is in the wlmf\cdma\bts–# folder.

Table 7-31: RX ATP Test

Step Action

1 Set up test equipment per Figure 7-19 or Figure 7-20.

2 Terminate diversity RX antenna inputs on FRU.

3 Enter the following commands to run the RX Acceptance Tests.

– Select the MAWI.

– Click on the Tests menu.

– Select ALL RX.

NOTE

The LMF refers to the antennas as Main and Diversity. On a Microcell, the Main is Antenna B

and the Diversity is Antenna A. On a Picocell, the Main is Antenna A and there is no Diversity or

Antenna B.

NOTE

Select Both in the RX Branch pick list if a diversity antenna is used.
