Unavailable Seconds (UAS)

This field is the time in seconds that the network port has been unavailable for data delivery. The T3 link is
down or in test or the signaling state is down.

Severely Errored Framing Seconds (SEFS)

This field indicates the number of seconds with one or more out-of-frame defects or a detected incoming
AIS.

Line Coding Violation (LCV)

This field is the number of bipolar violations (BPVs) and excessive zeros (EXZs) that have occurred.

Line Errored Seconds (LES)

This field is the number of seconds in which one or more CVs or one or more LOS defects occurred.

P-Bit Errored Seconds (PES)

This field indicates the number of seconds with one or more P-Bit Coding Violations (PCVs), one or more
out-of-frame defects, or a detected incoming AIS. This count is not incremented when UASs are counted.

P-Bit Severely Errored Seconds (PSES)

This field is the number of seconds with 44 or more PCVs, one or more out-of-frame defects, or a detected
incoming AIS. This count is not incremented when UASs are counted.

P-Bit Coding Violations (PCV)

This field is the number of coding violation (CV) error events that have occurred.

C-Bit Code Violations (CCV)

In C-Bit parity mode, this is a count of coding violations reported via the C-Bits or the number of C-Bit
parity errors that have occurred.

C-Bit Errored Seconds (CES)

This is the number of seconds with one or more CCVs, one or more out-of-frame defects, or a detected
incoming AIS. This count is not incremented when UASs are counted.

C-Bit Severely Errored Seconds (CSES)

This is the number of seconds with 44 or more CCVs, one or more out-of-frame defects, or a detected
incoming AIS. This count is not incremented when UASs are counted.
