Modification of any service has far reaching effects on communications or event reporting
capability. Nortel Networks strongly recommends you consult with your support group prior to
using the service manager interface.
There are two categories of services:
• System level services: Software processes that are critical to essential operating system level
features (see “System-Level Service Definitions” on page 252)
• Nortel Networks configurable services: Software processes that are critical to the operation of
the Business Communications Manager software (see “Nortel Networks Configurable
Services” on page 278)
Log management overview
This section describes the Media Service Card (core telephony) logs. All components of the
Business Communications Manager are logged and hence, the system generates a large number of
logs for a variety of purposes. In the case of faults, consult the logs to assist in the diagnosis and
correction of the problem.
Some of the logs run continuously and collect information to help you troubleshoot in the event of
system problems. The network administrator is able to disable some logs because the information
collected may not be of immediate or critical interest to maintain the health of the system.
The system generates the following MSC logs:
• MSC System Test Log: Contains diagnostic test results, telephony events and alarms, audits.
It has a maximum size of 20 items, after which events are aged out to make room for new
events.
• MSC System Administration Log: Contains log-in, log-out information. Has a maximum of
10 entries. The 11th entry overwrites the 1st entry regardless of severity level.
• MSC Network Event log: Contains T1 / PRI network interface events and alarms. This log
has a maximum size of 10 events.
For further information on Business Communications Manager logs, refer to Chapter 4, “Log
Management System,” on page 309.
BCM Monitor overview
