Performance Monitoring Parameters (continued)
Definition
Unavailable Seconds Path (UASP-P) is a count of one-second intervals
when the DS-3 path is unavailable. A DS-3 path becomes unavailable
when ten consecutive SESP-Ps occur. The ten SESP-Ps are included in
unavailable time. After the DS-3 path becomes unavailable, it becomes
available again when ten consecutive seconds with no SESP-Ps occur. The
ten seconds with no SESP-Ps are excluded from unavailable time.
Section Monitoring Unavailable Seconds (UAS-SM) indicates the
unavailable seconds recorded in the OTN section during the PM time
interval.
Unavailable Seconds VT Layer (UAS-V) is a count of the seconds when
the VT path was unavailable. A VT path becomes unavailable when ten
consecutive seconds occur that qualify as SES-Vs, and it continues to be
unavailable until ten consecutive seconds occur that do not qualify as
SES-Vs.
Uncorrectable Words (UNC-WORDS) is the number of uncorrectable
words detected in the DWDM trunk line during the PM time interval.
Valid Packets (VPC) is a count of received packets that contain
non-errored data code groups that have start and end delimiters.
shows signal types that support near-end and far-end PMs.
