Description
Severely Errored
Framing Seconds
Default:
0000000000
Range: N/A
Format: Numeric
A count of the number of severely errored fram-
ing seconds encountered by the DS3 port in one
of the previous 96 individual 15-minute inter-
vals. A severely errored framing second has one
or more out-of-frame defects or a detected AIS
defect.
Unavailable Sec-
onds
Default:
0000000000
Range: N/A
Format: Numeric
A count of the number of unavailable seconds
encountered by the DS3 port in one of the previ-
ous 96 individual 15-minute intervals. Unavail-
able seconds (UAS) are calculated by the number
of seconds that the interface is unavailable.
Line Coding Viola-
tions
Default:
0000000000
Range: N/A
Format: Numeric
A count of the number of line coding violations
that have occurred on the DS3 port since the last
time statistics were reset. Line coding violations
indicate that a bipolar violation or an excessive
zeroes error event has occurred.
Line Errored Sec-
onds
Default:
0000000000
Range: N/A
Format: Numeric
A count of the number of line errored seconds
encountered by the DS3 port in the previous
24-hour period. A line errored second is a second
in which one or more line code violation error
events were detected.
P-bit Coding Viola-
tions
Default:
0000000000
Range: N/A
Format: Numeric
For all DS3 applications, a coding violation 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.
P-bit Errored Sec-
onds
Default:
0000000000
Range: N/A
Format: Numeric
A second with one of the following:
•
one or more P-bit coding violations
•
one or more out of frame defects
•
a detected incoming alarm indication signal
(AIS)
This counter will not increment when unavail-
able seconds are counted.
P-bit Severely
Errored Seconds
Default:
0000000000
Range: N/A
Format: Numeric
A second with one of the following:
•
44 or more P-bit coding violations
•
one or more out of frame defects
•
a detected AIS
This counter will not increment when unavail-
able seconds are counted.
