Core telephony alarms are sent to both the MSC (core telephony) and the NT Event log systems.
The Business Communications Manager generates NT event alarms that relate to events that occur
in the voice software component. Use the log descriptions in conjunction with the voice software
component alarms to resolve events with a severity level of P5 and above. For further information
on alarms refer to Chapter 2, “Fault Management System. For specific information on the voice
software component alarms, refer to “Voice software” on page 211.
The logs display the following information:
• Description (MSC event or alarm number)
• Severity (1 - 9)
• Repeats (number of occurrences for this event)
• Time (format: yyyymmddhhmmss, e.g. 20030627135318)
• Parameters (report this information to Nortel Network support for debugging purposes - the
field displays information on port numbers, internal software variables, buffer numbers)
