11.5 Performance Monitoring for Electrical Ports
The following sections define PM parameters for the E1 and DS3 electrical ports.
UASCP-PFE Unavailable Seconds CP-bit Far End Path (UASCP-PFE) is a count of
one-second intervals when the DS3 path becomes unavailable. A DS3 path
becomes unavailable when ten consecutive far-end CP-bit SESs occur. The
ten CP-bit SESs are included in unavailable time. After the DS3 path
becomes unavailable, it becomes available when ten consecutive seconds
occur with no CP-bit SESs. The ten seconds with no CP-bit SESs are
excluded from unavailable time.
UAS-P Path Unavailable Seconds (UAS-P) is a count of the seconds when the path
was unavailable. A path becomes unavailable when ten consecutive
seconds occur that qualify as P-SESs, and it continues to be unavailable
until ten consecutive seconds occur that do not qualify as P-SESs.
UAS-PFE Far-End Path Unavailable Seconds (UAS-PFE) is a count of the seconds
when the path was unavailable. A path becomes unavailable when ten
consecutive seconds occur that qualify as P-SESs, and it continues to be
unavailable until ten consecutive seconds occur that do not qualify as
P-SESs.
UAS-PM Path Monitoring Unavailable Seconds (UAS-PM) indicates the unavailable
seconds recorded in the OTN path during the PM time interval.
UASP-P Unavailable Second Path (UASP-P) is a count of one-second intervals
when the DS3 path is unavailable. A DS3/E3 path becomes unavailable
when ten consecutive SESP-Ps occur. The ten SESP-Ps are included in
unavailable time. After the DS3 path becomes unavailable, it becomes
available when ten consecutive seconds with no SESP-Ps occur. The ten
seconds with no SESP-Ps are excluded from unavailable time.
UAS-SM Section Monitoring Unavailable Seconds (UAS-SM) indicates the
unavailable seconds recorded in the OTN section during the PM time
interval.
UNC-WORDS The number of uncorrectable words detected in the DWDM trunk line
during the PM time interval.
VPC A count of received packets that contain non-errored data code groups that
have start and end delimiters.
1. 4-fiber MS-SPRing is not supported on the STM-4 and STM4 SH 1310-4 cards; therefore, the MS-PSC-S and MS-PSC-R PM
parameters do not increment.
