t3CurrentConfig { 1.3.6.1.4.1.425.2.8.1.4 } This table defines the PRISM 3301 (TR 54014)
Performance Monitoring table.
t3IntervalConfig { 1.3.6.1.4.1.425.2.8.1.5 } The Interval Table contains various statistics collected
by the PRISM 3301 over the previous 24 hours of operation. The past 24 hours are
broken into 96 completed 15-minute intervals.
Object Name Object ID User Access Object Description
t3CurrentIndex t3CurrentConfigEntry 1 read-only The value for this object is equal to the value of IfIndex from the
Interfaces table of MIB II (RFC 1213).
t3CurrentESA t3CurrentConfigEntry 2 read-only Errored Seconds Type A(ES-A) in the current 15 minute interval. An
ES-A is a second with exactly one errored M-frame, and no occurrence
of any LOS, OOF or AIS condition.
t3CurrentESB t3CurrentConfigEntry 3 read-only Errored Seconds Type B(ES-B) in the current 15 minute interval. An
ES-B is a second with more than one, but less than or equal to 44
errored M-frames, and no occurrence of any LOS, OOF AIS condition.
t3CurrentESC t3CurrentConfigEntry 4 read-only Errored Seconds Type C(ES-C) in the current 15 minute interval. An
ES-C is a second with more than 44 errored M-frames and/or an LOS,
OOF or AIS condition.
t3CurrentPESF t3CurrentConfigEntry 4 read-only Percent Error-Free Seconds (PEFS) in the current 15 minute interval.
An Error Free Second(EFS) for a DS3 channel is defined as any
second of transmission in which no bit errors are received. In other
words, all the 44,736,000 bits received in a second are received as
transmitted. The proportion of error free seconds is the ratio of
one-second intervals not containing any bit errors to the total number
of seconds in an observation period, which is usually 24 hours. This
proportion is expressed as PEFS.
t3CurrentSES t3CurrentConfigEntry 6 read-only Severely Errored Seconds(SES) in the current 15 minute interval. A
severely errored second is defined as any second in which the bit error
ratio is worse than 1x10
-3 .
t3CurrentSFE t3CurrentConfigEntry 7 read-only Short Failure Event (SFE) in the current 15 minute interval. A failure
event begins with either 10 SES, or 3 or more seconds of continuous
loss of signal integrity (e.g., LOS, high bit error ratio, or AIS
condition) and ends at the beginning of a 10 SES-free period.
Object Name Object ID User Access Object Description
t3IntervalIndex t3IntervalConfigEntry 1 read-only The value for this object is equal to the value of IfIndex from the
Interfaces table of MIB II (RFC 1213).
t3IntervalNumber t3IntervalConfigEntry 2 read-only A number between 1 and 96, where 1 is the most recently completed
15 minutes interval and 96 is the least recently completed 15 minutes
interval (assuming that all 96 intervals are valid).
t3IntervalESA t3IntervalConfigEntry 3 read-only Errored Seconds Type A(ES-A) in the specified individual 15 minute
interval. An ES-A is a second with exactly one errored M-frame, and
no occurrence of any LOS, OOF or AIS condition.
t3IntervalESB t3IntervalConfigEntry 4 read-only Errored Seconds Type B(ES-B) in the specified individual 15 minute
interval. An ES-B is a second with more than one, but less than or
equal to 44 errored M-frames, and no occurrence of any LOS, OOF
AIS condition.
t3IntervalESC t3IntervalConfigEntry 5 read-only Errored Seconds Type C(ES-C) in the specified individual 15 minute
interval. An ES-C is a second with more than 44 errored M-frames
and/or an LOS, OOF or AIS condition.
