126 No Circuit Configured in the MSC

Description

The BSC sends a circuit maintenance (such as resetting a circuit) message to the MSC, but the MSC is not configured with the corresponding circuit, the MSC sends the "The circuit is not configured" message to the BSC. The BSC reports this alarm.

126 Minor Event

Parameters

ID Name Meaning
1 DPCGROUP

DPCGROUP of the circuit that is not configured

2 CicNum

BSC Circuit identification code (CIC) numbers of the circuits those are not configured

3 CIC

BSC Circuit identification code (CIC) of the circuit that is not configured

4 OSP

Original signaling point (OSP) of the subrack where the circuit is located

5 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".

Impact on the System

The MSC does not assign a circuit that is not configured in the MSC, no impact is caused on the system.

System Actions

The BSC does nothing but receives the "The circuit is not configured" message from the MSC.

Possible Causes

  • The CIC configuration in the BSC is inconsistent with that in the MSC. For example, the number of configured CICs or the CIC range is different.
  • The circuit state configured in the BSC is inconsistent with that configured in the MSC.

Procedure

  1. Check whether the CIC configuration (for example, the number of configured CICs or the CIC scope) in the MSC is not consistent with that in the BSC.

    Y => Delete redundant CIC data from the BSC, or add required CIC data into the MSC.

    N => Go to 2.

  2. Check whether the circuit state configured in the MSC is not consistent with that configured in the BSC.

    Y => Modify the circuit state configuration in the BSC or in the MSC and ensure that the BSC and the MSC are consistent in the circuit state configuration.

    N=> Please contact Huawei Customer Service Center.
