Parameters

When you view an alarm on the network management system, select the alarm. In the Alarm Details field display the related parameters of the alarm. The alarm parameters are in the following format: Alarm Parameters (hex): parameter1 parameter2...parameterN. For details about each parameter, refer to the following table.

Name Meaning

Parameter 1

Indicates the optical interface number. The value is always 0x01.

Parameter 2, Parameter 3

Indicates the VCTRUNK port number.

Impact on the System

The paths configured in the receive direction are not used, so the available bandwidth is zero.

Possible Causes

The possible causes of the LCAS_TLCR alarm are as follows:

  • When the LCAS function of the VCTRUNK is enabled, in the receive direction, the number of paths that carry load is zero, whereas the number of paths configured is not zero.

Procedure

  1. Check the service configurations of the local and opposite station. Check whether the bound paths of the VCTRUNK are consistent. If any error exists, reconfigure the values.
  2. Check whether the configured path reports SDH alarms. If yes, see the handling procedure of the corresponding alarm.
