LP_TIM

LP_TIM

Description

The LP_TIM alarm indicates inconsistent lower order path trace identifiers. This alarm is generated when a board detects inconsistent J2 or J1 bytes.

Attribute

Alarm Severity Alarm Type

Minor

Communication alarm

Parameters

None.

Impact on the System

This alarm does not have any impact on the system.

Possible Causes

Possible causes of this alarm are as follows:

  • The lower order path trace identifier at the local end is inconsistent with that at the opposite end.
  • The service cross-connections are incorrectly configured.

Procedure

  1. View the LP_TIM alarm on the U2000 to determine the ID of the path where the LP_TIM alarm is generated.
  2. Ensure that the lower order path trace identifier on the tributary board at the opposite end is consistent with that on the line board at the local end. Then, check whether the LP_TIM alarm is cleared.
  3. If the alarm persists, check whether the service cross-connection configuration of the path on the tributary board that reports the alarm is correct. After modifying the incorrect configuration, check whether the LP_TIM alarm is cleared.
  4. If the alarm persists, perform a self-loop at the local end to check whether the board at the local or opposite end is faulty. Then, replace the faulty board.
