Unsolicited alarms

Any of the tasks on the TX processor (including any of the SS7 layers) can generate unsolicited alarms at any time to indicate abnormal events or changes in the status of an entity. The txalarm utility is provided to receive alarms and write them to a disk file on the host.

The following table displays the alarm text and the alarm number. The headings are the code from the txalarm utility for these fields (ap is an alarm pointer).

Note: Inbound and outbound calls reuse certain alarm numbers. Any code looking for these alarms must check the call state of the circuit, as well as the string of the alarm.

If these messages are generated by a timer popping, it is noted in parentheses after the alarm number.
