HP_TIM

HP_TIM

Description

The HP_TIM alarm indicates inconsistent higher order path trace identifiers (J1 bytes).

Attribute

Alarm Severity Alarm Type

Minor

Communication alarm

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 port number. The parameter has a fixed value of 0x01.

Parameter 2, Parameter 3

Indicate the VC-4 path ID.

Impact on the System

The services in the payload are unavailable, resulting in service interruption.

If the AIS insertion is enabled upon detection of the HP_TIM alarm, the local end sends the HP_RDI alarm to the opposite end.

Possible Causes

Possible causes of this alarm are as follows:

  • The higher order path trace identifier (J1 byte) that the local end is supposed to receive is inconsistent with the higher order path trace identifier (J1 byte) transmitted by the opposite end.
  • Service configurations are incorrect.
  • The transmit unit at the opposite end is faulty.
  • The receive unit at the local end is faulty.

Procedure

  1. Check whether the configuration of the higher order path trace identifier (J1 byte) that the local end is supposed to receive is consistent with the configuration of the higher order path trace identifier (J1 byte) transmitted by the opposite end.

    If... Then...

    The configuration of the higher order path trace identifier (J1 byte) that the local end is supposed to receive is inconsistent with the configuration of the higher order path trace identifier (J1 byte) transmitted by the opposite end

    Ensure that the configuration of the higher order path trace identifier (J1 byte) that the local end is supposed to receive is consistent with the configuration of the higher order path trace identifier (J1 byte) transmitted by the opposite end. Then, check whether the alarm is cleared. If the alarm persists, go to the next step.

    The configuration of the higher order path trace identifier (J1 byte) that the local end is supposed to receive is consistent with the configuration of the higher order path trace identifier (J1 byte) transmitted by the opposite end

    Go to the next step.

  2. Check whether service configurations at the local end and the opposite end are correct.

    If... Then...

    The service configurations are incorrect

    Correct the service configurations. Then, check whether the alarm is cleared. If the alarm persists, go to the next step.

    The service configurations are correct

    Go to the next step.

  3. Perform loopbacks at the local end and the opposite end to locate the faulty board.

    If... Then...

    A board at the opposite end reports the HP_SLM alarm

    The transmit unit at the opposite end is faulty. Replace the line board first. If the alarm persists, replace the system control, cross-connect, and timing board.

    A board at the local end reports the HP_SLM alarm

    The receive unit at the local end is faulty. Replace the faulty board.

  4. If the alarm persists, contact Huawei technical support engineers to handle the alarm.
