RSCSES

RSCSES

Performance Event Meaning

The RSCSES event indicates the regenerator section consecutive severely errored seconds.

Performance Event Attributes

Performance Event ID Performance Event Type

0x07

SDH performance event

Impact on the System

If bit errors occur in the services, identify the causes and rectify the fault immediately. Otherwise, alarms will be generated and the signal transmission quality will be affected. If bit errors exceed the B1 bit error threshold-crossing threshold and degrade threshold, the B1_EXC and B1_SD alarms will be generated.

Possible Causes

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

External causes:

  • The fiber performance is degraded, and the fiber has high attenuation.

  • The fiber connector is dirty or incorrect.

  • The equipment is poorly grounded.

  • There is a severe interference source around the equipment.

  • 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 is excessive, the transmit circuit at the opposite end is faulty, or the receive circuit at the local end is faulty.

  • The synchronization performance of the clock is poor.

  • The cross-connect unit and the line board poorly match.

  • The board becomes faulty, or the performance of the board is degraded.

Relevant Alarms

Alarm Name Correlation

B1_EXC

B1 bit errors crossing the threshold

B1_SD

Signals degraded (B1)

R_LOS

The signal on the receiver line side is lost.

R_LOF

The out-of-frame fault occurs on the receiver line side.

Procedure

  1. See RSES.

Reference

None.
