t3TotalConfig

{ 1.3.6.1.4.1.425.2.8.1.6 } The Total table contains the cumulative sum of the
various performance parameters for the 24-hour period preceding the current
interval.

t3IntervalPEFS

t3IntervalConfigEntry 6

read-only

Percent Error-Free Seconds (PEFS) in the specified individual 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 in this case is 15
minutes.

t3IntervalSES

t3IntervalConfigEntry 7

read-only

Severely Errored Seconds(SES) in the specified individual 15 minute
interval. A severely errored second is defined as any second in which
the bit error ratio is worse than 1x10

-3

.

t3IntervalSFE

t3IntervalConfigEntry 8

read-only

Short Failure Event (SFE) in the specified individual 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.

t3TotalIndex

t3TotalConfigEntry 1

read-only

The value for this object is equal to the value of IfIndex from the
Interfaces table of MIB II (RFC 1213).

t3TotalESA

t3TotalConfigEntry 2

read-only

Total Errored Seconds Type A(ES-A) in the previous 24 hour interval.
An ES-A is a second with exactly one errored M-frame, and no
occurrence of any LOS, OOF or AIS condition.

t3TotalESB

t3TotalConfigEntry 3

read-only

Errored Seconds Type B(ES-B) in the previous 24 hour 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.

t3TotalESC

t3TotalConfigEntry 4

read-only

Errored Seconds Type C(ES-C) in the previous 24 hour interval. An
ES-C is a second with more than 44 errored M-frames and/or an LOS,
OOF or AIS condition.

t3TotalPEFS

t3TotalConfigEntry 5

read-only

Percent Error-Free Seconds (PEFS) in the previous 24 hour 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 in this case is 24 hours.

t3TotalSES

t3TotalConfigEntry 6

read-only

Severely Errored Seconds(SES) in the previous 24 hour interval. A
severely errored second is defined as any second in which the bit error
ratio is worse than 1x10

-3

.

t3TotalSFE

t3TotalConfigEntry 7

read-only

Short Failure Event (SFE) in the previous 24 hour 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.
