TATISTICS
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 Path Performance Statistics The OC3/STM-1 Path Performance
Monitoring screen displays the following statistics:
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 — Indicates whether or not a Loss of Pointer (LOP) condition has been
encountered by the OC3/STM-1 path interface
AIS — Indicates whether or not an Alarm Indicator Signal (AIS) condition has been
encountered by the OC3/STM-1 path interface
RDI — Indicates whether or not a Remote Defect Indication (RDI) condition has
been 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 — Indicates whether or not an Unequipped (UEQ) condition has been
encountered by the OC3/STM-1 path interface. If a path is not provisioned (in
other words, it is idle), the SONET equipment will signal this state. This statistic is
listed as a numeric value (0 or 1), with 1 indicating that a UEQ condition exists.
PLM — Indicates whether or not a path signal label mismatch as been
encountered by the OC3/STM-1 interface. This statistic is listed as a numeric value
(0 or 1), with 1 indicating that a PLM condition exists.
OC3/STM-1 Far Path Performance Statistics The OC3/STM-1 Far Path
Performance Monitoring screen displays the following statistics:
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
