is a signal sent downstream as an indication that an
upstream defect has been detected.
AIS
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
Number of upstream connection locked alarms. LCK
is a signal sent downstream as an indication that
upstream the connection is locked, and no signal is
passed through.
LCK
Number of OTU loss of frame (LOF) alarms.
LOF
Number of OTU loss of multiframe (LOM) alarms.
LOM
Loopback status. Indicates whether or not loopback
is enabled and the type of loopback enabled.
