Attenuation of received signals is over great.

The peer sender fails.

The connector of fiber is dirty or improperly connected.
 The local receiver fails.
Critical
RS-LOF
 The Tx clock of the peer device fails.
 Optical signals do not match.
 The local Rx reference clock fails.
Critical
RS-TIM
 The received trace byte of the local device and the sent trace
byte of the peer device are inconsistent.
 Services are improperly configured.
Critical
AU-AIS
 The AU-AIS alarm of the VC4 channel is triggered by MS-
AIS, R-LOS, R-LOF alarms.
 Services are improperly configured.
 The peer device sends AU-AIS alarms.
 The sender of the peer device or the receiver of the local
device fails.
Minor
AU-LOP
 The sender of the peer device fails.
 Services are improperly configured on the peer device.

Bit Error Rate (BER) of the local device is over great.
Critical
MS-EXC

BER in the multiplexing section is over high.



The performance of the local card is bad.
Major
MS-AIS Multiplexing section alarm LED

Alarm signals are inserted in the optical signals sent by the
peer device.
