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.
