HAPTER ATH UILDER IAGNOSTICS AND ERFORMANCE ONITORING
Far Line Performance Monitoring (current, interval, and total)
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.
Path Performance Monitoring (current, interval, and total)
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.
Far Path Current Performance Monitoring (current, interval, and total)
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.
UAS—The number of far end unavailable seconds (UASs) encountered by the
OC3/STM-1 path interface.
CVS—The number of far end coding violations (CVs) encountered by the
OC3/STM-1 path interface.
OC3/STM-1 UNI ATM Statistics The OC3/STM-1 UNI ATM Statistics screen
displays the following statistics:
Cells Received—The number of ATM cells received on the OC3/STM-1 since the
last user reset of this counter.
