15.5 Performance Monitoring for Electrical Cards
The following sections define PM parameters for the EC1-12, DS1/E1-56, DS1-14, DS1N-14, DS3-12,
DS3-12E, DS3N-12, DS3N-12E, DS3i-N-12, DS3XM-6, DS3XM-12, and DS3/EC1-48 cards.

15.5.1 EC1-12 Card Performance Monitoring Parameters

Figure 15-2 shows signal types that support near-end and far-end PMs. Figure 15-3 shows where
overhead bytes detected on the application specific integrated circuits (ASICs) produce PM parameters
for the EC1-12 card.
Figure 15-2 Monitored Signal Types for the EC1-12 Card
UASP-P 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.
UAS-SM Section Monitoring Unavailable Seconds (UAS-SM) indicates the
unavailable seconds recorded in the OTN section during the PM time
interval.
UAS-V 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.
UNC-WORDS Uncorrectable Words (UNC-WORDS) is the number of uncorrectable
words detected in the DWDM trunk line during the PM time interval.
VPC Valid Packets (VPC) is a count of received packets that contain
non-errored data code groups that have start and end delimiters.
