Step Action

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

14 Open an MMI Communication session.

15 Enter the status command to verify that the BTS is in OOS_RAM status.

16 Enter the sndtype 0xa178 command to simulate an LMF connection.

17 Enter the gps_rx_debug nosats off command at the MMI prompt to disable the simulation of

the GPS losing tracked satellites.

NOTENOTE

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 7-11 (Synchronization Verification) to make sure the BTS is

tracking the RGPS.
