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.

Diagnostics → Selftest.
2. Do another Selftest (Reset) and check results.
– If the results are normal, the problem was transient. Log the
results.
– If the results are the same as the first selftest, the card should be
replaced. If only one port on a DSL card is bad, that port can be
disabled. You may continue to use the card until it is convenient
to replace it.
