Type
Degraded Minutes (those in which the incoming bit error rate is
between 10-6 and 10-3). These minutes are determined by
collecting all available seconds, removing SESs, grouping the
results in 60-second groups, and counting a 60-second group
as degraded if the total errors during those seconds exceed
-6
10
. Available seconds are those that are not UASs.
Line Code Violations (bipolar violations and excessive zeros.)
Type
Line Code Violations (number of line code violations detected
in the incoming signal).
Framing Block Errors (number of framing errors detected in the
incoming signal).
P-bit Errors (number of P-bit parity errors detected in the
incoming signal).
CP-bit Errors (number of CP-bit parity errors detected in the
incoming signal).
Far end Block Errors. Number of times the received FEBE bits
included a block error.
Change of Frame Alignment (number of times a frame
realignment occurred in the incoming signal).
Type
CRC Errors Events. Occur when the CRC-6 code calculated on
the previous superframe does not match the code for the current
superfame. These events are not counted during an RLOS
alarm condition.
Errored Seconds. Number of seconds in which one or more
EEV's are detected. This count is not advanced during a UAS
second.
Unavailable Seconds. Number of 1-second intervals during
which T1 service is not available. The service is declared
unavailable if 10 or more consecutive SES's are detected.
Bursty Errored Seconds. Number of 1-second intervals with
more than 1 but less that 320 CRC error events.
Severely Errored Seconds. Number of 1-second intervals with
320 or more EEV's, or one or more OOF events.
Loss of Frame Count. number of times a LOF is detected. The
alarm declaration and clearing times are defined in AT&T
TR-54016.
