R3851a:CELL_LOCALSWITCH_LOOP_RESTORE_APPLY_TRSL_FAIL_BTS_LOOP
During the process where the BTS loopback is restored to a normal call, the BSC sends a link connection command to the BTS. The Abis territorial transmission resources mapped to the Um interface channel are requested. Within the BSC, the transmission channel between the Ater interface and the Abis interface is reconnected and TC resources are requested. If the request for Abis resources, the reconnection, or the request for TC resources fails, the cause value in the loopback acknowledgement message is Territorial Resource Request Failure. Then, the BSC regards it as a call drop and releases the call directly.
This measurement provides the number of failures to return to normal call from BTS loopback due to territorial resource request failure.
Integer number or integer.
