I know I'm back in late on this, but I was just checking a problematic circuit on my network and though I'd post the results just to show what one can look at on a cisco router wan interface card (WIC).
Here's the "sh service-module" command:
Module type is T1/fractional
Hardware revision is 0.88, Software revision is 0.2,
Image checksum is 0x70F47262, Protocol revision is 0.1
Receiver has no alarms.
Framing is ESF, Line Code is B8ZS, Current clock source is line,
Fraction has 6 timeslots (64 Kbits/sec each), Net bandwidth is 384 Kbits/sec.
Last module self-test (done at startup): Passed
Last clearing of alarm counters 3d21h
loss of signal : 0,
loss of frame : 0,
AIS alarm : 0,
Remote alarm : 0,
Module access errors : 0,
Total Data (last 96 15 minute intervals):
0 Line Code Violations, 3 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 1694 Degraded Mins
3 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Data in current interval (211 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
