*Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the appropriate test description and follow the recommended procedures.
**Major alarms may be downgraded to Warning alarms based on the value used in the set options command.
Notes:
See also the preceding section on trunk problems without errors or alarms.
(a) This condition occurs when the tone detector times out waiting for digits. Change wink/immediate-start parameter to wink/immediate-start and rotary/tone-dial parameters.
(e) This is a software audit error that does not indicate any hardware malfunction. Run Short Test Sequence and investigate associated errors (if any).
(f) This error type indicates that the Media Module has been removed or has been insane for more than 11 minutes. To clear the error, reinsert or replace the Media Module.
(g) Rotary dial pulse on-hook longer than 105 msec -- Break between rotary pulses is too long.
Test trunk by performing an incoming test call.
Refer problem to CO.
(h) Rotary dial rate below 8 pulses/sec -- More than 135 msec between two successive breaks.
(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.
Verify the interface to the network with a hand telephone set. If calls are placed correctly, then refer problem to the CO.
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.
