k. Loop current active — CO not releasing trunk after PBX disconnect.
Occurs when the PBX end drops first and the CO does not release the
trunk within 4 minutes.
1. Verify the interface to the network with a hand telephone set. If calls
are placed correctly, then refer problem to the CO.
2. If unable to place calls or this equipment is not available, check the
status on port using the status trunk command. If active but not
connected, disconnect bridging clips at the network interface.
Check status on the trunk. If trunk went idle, then replace clips. If
trunk is still active but unable to place calls, refer problem to the CO.
l. Late CO trunk release — This event only occurs after the occurrence of
Error Type 513. The CO released the trunk 4 minutes after the PBX
dropped the call. This event decrements the severity (error count) of Error
Type 513, or may mean the problem related to Error Type 513 has been
fixed.
Verify that Error Type 513 does not occur again. Refer to Error 513.
m. Incomplete Dial timer expired. This error only applies to the TN459 and
indicates a problem with incoming dialing stream. Refer the problem to the
CO.
