R3851c: CELL_LOCALSWITCH_LOOP_RESTORE_FAIL_BTS_LOOP_SERVICE
During the process where the BTS loopback is restored to a normal call, the call processing module initiates a loopback recovery request in the BSC. If the loopback fails because of various reasons (including the TC resource request failure, the failure to establish the transmission channel between the Ater interface and the Abis interface, and other reasons), a loopback recovery acknowledgment message is returned to the call processing module initiating the loopback recovery. Then, the BSC regards it as a call drop and releases the call directly.
If the BTS loopback recovery request message is sent because of service requirements, the counter is measured after the loopback recovery fails.
Integer number or integer.
If the BTS loopback recovery is triggered because of service requirements, this counter is measured after the loopback recovery fails.
This is an original counter without involving any formula.
