Major Alarm Inquiry Test (#142)
The Major alarm raised by a DS1 Interface circuit pack indicates that the average
bit error rate on the DS1 facility is greater than 1/1000. The Major Alarm Inquiry
Test is used to determine that the received DS1 bit error rate is greater than
1/1000. When D4 framing mode is selected, the DS1 Interface circuit pack takes
16 seconds to recognize and report a Major alarm and 16 seconds to recognize
and report that a Major alarm condition is cleared. If ESF framing mode is
selected, the DS1 Interface circuit pack takes 10 seconds to recognize and report
a Major alarm and 10 seconds to recognize and report that a Major alarm
condition is cleared.
When the DS1 Interface circuit pack detects a Major alarm, it will send a
MAJOR-ALARM message to the maintenance software. After the maintenance
software receives a MAJOR-ALARM message, the Major Alarm Inquiry Test is
initiated to confirm the Major alarm on the DS1 Interface circuit pack. The Inquiry
Test will be run every 10 minutes until the Major alarm is cleared. The
maintenance software places all trunks on the circuit pack in the out-of-service
state if the Major alarm persists for more than 20 minutes.
When the Major alarm is cleared, the maintenance software restores all trunks on
the circuit pack to their previous service state before a Major alarm occurs.
