T3, E3, T1, E1 Controller Commands on the Cisco ASR 9000 Series Router
Description
Framing type on the channelized controller.
Clock source controller. Values are internal and line.
Line Code Violations (LCVs) is a count of both
Bipolar Violations (BPVs) and Excessive Zeros
(EXZs) that occur over the accumulation period. An
EXZ increments the LCV by one regardless of the
length of the zero string.
For all DS3 applications, a P-bit coding violation
(PCV) error event is a P-bit parity error event. A P-bit
parity error event is the occurrence of a received P-bit
code on the DS3 M-frame that is not identical to the
corresponding locally calculated code.
Controlled slip second (CSS) is a 1-second interval
that contains one or more controlled slips.
Frame loss seconds (SELS) is the number of seconds
for which an out-of-frame error is detected.
Line errored seconds (LES) is a second in which one
or more line code violation errors are detected.
Degraded minute (DM) is a minute in which the
estimated error rate exceeds 1E-6 but does not exceed
1E-3. For more information, see RFC 1406,
Definitions of Managed Objects for DS1 and E1
Interface Types.
Errored seconds (ES) is a second with one or more
path coding violations, one or more out-of-frame
defects, or one or more controlled slip events or a
detected AIS defect.
Bursty errored seconds (BES) is a second with fewer
than 320 and more than one path coding violation
error events, no severely errored frame defects, and
no detected incoming AIS defects. Controlled slips
are not included in this parameter.
Severely errored seconds (SES) is a second with 320
or more path code violation errors events, one or more
out-of-frame defects, or a detected AIS defect.
Number of seconds during which the interface was
not available in this interval, referred to as UAS.
