Lists the alarms that are enabled for reporting.Alarm reporting enabled for
Alarms indicated to be reported by the user.Asserted Alarms
Number of backward defect indication (BDI) alarms.
The BDI is a single bit that conveys information
regarding signal failure in the upstream direction.
BDI
Values of the configured bit error rate thresholds.BER thresholds
Number of bit interleaved parity alarms. The BIP is
comprised of one byte and is used for error detection.
It is computed over the entire optical channel payload
unit (OPU).
BIP
Status of the controller.Controller State
Alarms detected by the hardware.Detected Alarms
Corrected code words. This is the number of words
corrected by the FEC and is displayed as a per second
rate.
EC
Indicates the forward error correction (FEC) mode
for the controller. This can be Disabled, Enhanced
FEC G.975.1 1.4, or Standard FEC (Default).
FEC Mode
Number of incoming alignment errors (IAE).IAE
