Clearing Circuit Releasing Failed in CAS alarms:
The alarm that you are talking about happens on MF circuits and is caused by the LEC not releasing or acknowledging us quick enough. Do to the latency, the Nokia locks out the trunk in question. When you see this alarm you should assume that it is 911 related and the issue needs to be corrected ASAP. The alarm field will be shown below.
SLMSC001 CASU-1 SWITCH 2005-11-27 00:07:37.44
*** ALARM CASU-1 1E001-00 SI9_SO
(9952) 2153 CIRCUIT RELEASING FAILED IN CAS
1081d 13d 29 0823 01 FF 01 02 01 01 10 00 00 00
If you look above I have highlighted in red the circuit that needs to be reset (1081-13). If you take the circuit to a NU state for about 30 seconds and then back to WO it should clear.
ZCEC:CRCT=1081-1:BA;
ZCEC:CRCT=1081-1:NU;
ZCEC:CRCT=1081-1:BA;
ZCEC:CRCT=1081-1:WO;
Also, you should get a Low Traffic Capacity alarm with supplementary information. I have the alarm listed below and the supplementary info is in red (02 0386). If you convert 386 from HEX to Decimal it comes out to 902. At that time you can do the command ZRCI:SEA=3:CGR=902:PRINT=5:; and look at the circuit group.
