Minor Alarm Inquiry Test (#143) - Avaya G700 Maintenance Manual

6 Avaya MultiVantage Software-Controlled Maintenance:

Minor Alarm Inquiry Test (#143)

The Minor alarm raised by a DS1-MM Interface Media Module indicates that the average bit error
rate on the DS1 facility is greater than 1/1,000,000, but less than 1/1000. The Minor Alarm Inquiry
Test is used to determine that the received DS1 bit error rate is greater than 1/1,000,000 and less than
1/1000. When D4 framing mode is selected, the DS1-MM Interface Media Module takes 41-minutes
to recognize and report a Minor alarm and 41-minutes to recognize and report that a Minor alarm
condition has cleared. If ESF framing mode is selected, the DS1-MM Interface Media Module takes
10 minutes to recognize and report a Minor alarm and 10 minutes to recognize and report that a Minor
alarm condition has cleared.
When the DS1-MM Interface Media Module detects a Minor alarm condition, it sends a MINOR-
ALARM message to the maintenance software. After the maintenance software receives a MINOR-
ALARM message, the Minor Alarm Inquiry Test is initiated to confirm the Minor alarm. All trunks
or ports on the Media Module are kept in the in-service state after the Minor alarm is confirmed. The
Minor Alarm Inquiry Test runs every 10 minutes until the Minor alarm is cleared.

Description/ Recommendation
Internal system error
Retry the command at 1-minute intervals a maximum of 5 times.
Response to the test was not received within the allowable time
period. This may be due to hyperactivity. Error Type 1538 in the error
log indicates hyperactivity. The hyperactive Media Module is out of
service and one or more of the following symptoms may be exhibited.
The DS1-MM tests (such as Test #138 and Test #139) are aborting
with error code 2000.
The tests run on the ports of this Media Module are returning a no
board result.
A busyout or a release command has no affect on the test results.
A list config command shows that the Media Module and the ports
are properly installed.
When hyperactivity occurs, the Media Module is isolated from the
system, and all of the trunks for this Media Module are placed into
the out of service state. The system will try to restore the Media
Module within 15 minutes. When no faults are detected for 15
minutes, the DS1-MM interface Media Module is restored to normal
operation. All of the trunks for the DS1-MM interface Media Module
are then returned to the in service state. Hyperactivity is often caused
by the associated facility. In such a case, faults (such as slips,
misframes, or blue alarms) would be entered in the error log. In
addition, many hardware errors would be logged against the
associated trunk circuits. If the facility is OK and the error occurs
again after 15 minutes, replace the Media Module.
