Impact on the System

If bit errors occur in the services on a remote NE but no related alarms are reported on the remote NE, the system will not be affected. However, it is required to identify the causes and rectify the fault immediately. Otherwise, alarms will be generated and the signal transmission quality will be affected.

Possible Causes

The MSFEBBE event is an errored block not occurring as part of multiplex section far end unavailable time and multiplex section far end severely errored second.

External causes:

  • The fiber performance degrades and the attenuation is excessive at the opposite station.

  • The fiber connector is dirty or incorrect at the opposite station.
  • The equipment is poorly grounded at the opposite station.
  • There is a severe interference source around the equipment at the opposite station.
  • The working temperature is high or low, and the opposite equipment cannot tolerate such temperature.

Equipment problems:

  • The signal attenuation on the receive side of the line board at the opposite station is excessive, or the transmit circuit at the opposite station is faulty, or the receive circuit at the local station is faulty.

  • The synchronization performance of the clock is poor at the opposite station.
  • The cross-connect unit and the line board poorly match at the opposite station.
  • The fan of the opposite equipment becomes faulty.
  • The board fails or the board performance degrades at the opposite station.
