Viewing Statistics 231
UAS—The number of unavailable seconds (UASs) encountered by the OC3/STM-1
line.
CVS—The number of coding violations (CVs) encountered by the OC3/STM-1 line.
AIS—The number of Alarm Indicator Signal (AIS) conditions encountered by the
OC3/STM-1 line.
RDI—The number of Remote Defect Indication (RDI) conditions encountered by
the OC3/STM-1 interface. Also known as FERF (Far End Receive Failure). This is the
alarm that is generated when a far end AIS or LOP defect is detected.
OC3/STM-1 UNI Far Line Performance Monitoring
ES—The number of far end errored seconds (ESs) encountered by the OC3/STM-1
interface.
SES—The number of far end severely-errored seconds (SESs) encountered by the
OC3/STM-1 interface.
UAS—The number of far end unavailable seconds (UASs) encountered by the
OC3/STM-1 interface.
CVS—The number of far end coding violations (CVs) encountered by the
OC3/STM-1 interface.
OC3/STM-1 UNI Path Performance Monitoring
ES—The number of errored seconds (ESs) encountered by the OC3/STM-1 path
interface.
SES—The number of severely-errored seconds (SESs) encountered by the
OC3/STM-1 path interface.
UAS—The number of unavailable seconds (UASs) encountered by the OC3/STM-1
path interface.
CVS—The number of coding violations (CVs) encountered by the OC3/STM-1 path
interface.
LOP—The number of Loss of Pointer (LOP) conditions encountered by the
OC3/STM-1 path interface.
AIS—The number of Alarm Indicator Signal (AIS) conditions encountered by the
OC3/STM-1 path interface.
RDI—The number of Remote Defect Indication (RDI) conditions encountered by
the OC3/STM-1 path interface. Also known as FERF (Far End Receive Failure). This
is the alarm that is generated when a far end AIS or LOP defect is detected.
UEQ—The number of Unequipped (UEQ) conditions encountered by the
OC3/STM-1 path interface. If a path is not provisioned (i.e. it is idle), the SONET
equipment will signal this state.
PLM—Physical Layer Module.
OC3/STM-1 UNI Far Path Current Performance Monitoring
ES—The number of far end errored seconds (ESs) encountered by the OC3/STM-1
path interface.
SES—The number of far end severely-errored seconds (SESs) encountered by the
OC3/STM-1 path interface.
