8.5.3 DS3 and DS3N Card Performance Monitoring Parameters
Figure 8-15 shows the signal types that support far-end PMs. Figure 8-16 shows where overhead bytes
detected on the ASICs produce performance monitoring parameters for the DS3 and DS3N cards.

Parameter Definition
CV-V
Far-End VT Path Coding Violations (CV-VFE) is a count of the number
of BIP errors detected by the far-end VT path terminating equipment
(PTE) and reported back to the near-end VT PTE using the REI-V
indication in the VT path overhead. Only one BIP error can be indicated
per VT superframe using the REI-V bit. The current CV-VFE second
register is incremented for each BIP error indicated by the incoming
REI-V.
ES-V
Far-End VT Path Errored Seconds (ES-VFE) is a count of the seconds
when at least one VT path BIP error was reported by the far-end VT PTE,
or a one-bit RDI-V defect was present.
SES-V
Far-End VT Path Severely Errored Seconds (SES-VFE) is a count of the
seconds when K (600) or more VT path BIP errors were reported by the
far-end VT PTE or a one-bit RDI-V defect was present.
UAS-V
Far-End VT Path Unavailable Seconds (UAS-VFE) is a count of the
seconds when the VT path is unavailable at the far-end. A VT path is
unavailable at the far-end when ten consecutive seconds occur that qualify
as SES-VFEs.
