0x38

SDH performance event

Impact on the System

If bit errors occur in the services on a remote NE, identify the causes and rectify the fault immediately. Otherwise, alarms will be generated and the signal transmission quality will be affected.

Possible Causes

When a consecutive HPFESES sequence is detected, the HPFECSES event occurs. When unavailable time comes or HPFESES is absent in one second, the HPFECSES sequence ends.

External causes:

  • On the opposite equipment, the fiber performance is degraded, and the fiber has high attenuation.

  • The fiber connector is dirty or incorrect at the opposite station.
  • The opposite equipment is poorly grounded.
  • 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 of the opposite equipment becomes faulty or the performance of the board is degraded.
