Diagnostics and Troubleshooting

Checking Alarms

If the Card Selection screen indicates that a Major or Minor Alarm is on a card, follow the menu sequence Diagnostics Alarms (D-B) to determine the cause of the alarm.

NOTE:

If a DSL card does not appear on the Card Selection screen because the MCC card can no longer communicate with it, the MCC card will generate a major alarm. You should go to the MCC's Monitor Card Status Syslog (A-A-C) and view the event on its system log.

Major Alarms

Use Table 8-3 to determine the appropriate action to take for each Major Alarm.
