Description

This alarm is reported when the M3UA link is faulty.

Alarm ID	Alarm Severity	Alarm Type
701	Major	Fault

ID	Name	Meaning
1	Subrack No.	Number of the subrack for the M3UA link
2	Slot No.	Slot No.
3	Cpu No.	CPU No.
4	M3UA Link No.	M3UA Link No.
5	Cause	0=indicates that the ASP ACTIVE or ASP ACTIVE ACK message is received,1=indicates that the signaling link is deactivated at the local end,2=indicates that the signaling link is deactivated at the peer end,17=indicates that the ASP DOWN ACK message is received,65=indicates that the ASP DOWN message is received,32=indicates that the signaling link is released at the local end,49=indicates that the establishment of the signaling link fails,50=indicates that the signaling link restart is initiated at the peer end,52=indicates that there is no valid IP address,64=indicates that the signaling link release is initiated at the peer end,254=indicates the initial user configuration,255=indicates other reasons
6	Alarm Attribute	0=Normal, Alarms period are longer than the Transient Threshold. 1=Transient Count, The times and the period of the alarms whose periods are shorter than the Transient Threshold are summed up. If the sum result is longer than the Alarm Occurrence Period Threshold or Alarm Occurrence Times Threshold, an alarm so called Transient Count Alarm is triggered. Because Transient Count Alarm is based on accumulative result, the recovery of the alarm may occur at least one Summing Cycle later. The Summing Cycle can be query by MML "LST STATSLDWIN".

If there is not any other available links in the link set, the route of the link set is unavailable.
If the DSP of some route does not have other available routes, the DSP cannot be visited. An alarm is generated indicating that the destination point is inaccessible.

The M3UA link will be re-established periodically. If the alarm is cleared, the signaling link resumes normal operation.

Check whether the link is unavailable for more than six seconds.
Y => Go to 3.

N => The signaling link is restored in six seconds. Go to 2.
Check whether a GFUGA/GOGUA switchover occurs.
Y => Add a signaling link.

N => Go to 3.
Through the LMT, check whether the 21205 Board Fault alarm is generated.
Y => Clear the alarm by referring to the relative handling suggestion.

N => If the alarm is cleared or does not exist, but the alarm cannot be cleared, go to [4].
Check whether the link is deactivated.
Y => Activate the corresponding link. The alarm handling is complete.

N => Please contact Huawei Customer Service Center.
