4.5. “Event counters” command
Use “
Event counters
” command to get more detailed information about counters.
Alive: 0 days, 18:04:39 since last counter clear
Link counters
CV = 0 - coding violations
0 - total code violations
OOS = 52 - seconds without carrier
Err = 0 - seconds with CRC error(s), LOSW defect(s) or BERT errors
0 - total CRC errors
Event = 1 - seconds with jitter attenuator error(s) or S(H)DSL slip(s)
0 - total jitter attenuator errors
0 - seconds with jitter attenuator error(s)
0 - jitter attenuator FIFO overflow errors
2 - jitter attenuator FIFO underflow errors
1 - seconds with jitter attenuator FIFO error(s)
0 - TFSC jerks
0 - seconds with TFSC jerk(s)
0 - receive slip events
0 - transmit slip events
0 - seconds with slip event(s)

SHDSL link counters:
• total code violations – total number of encoding errors;
• total CRC errors – total number of received blocks with wrong CRC;
• total jitter attenuator errors – total number of jitter attenuator errors;
• seconds with jitter attenuator error(s) – seconds, during which jitter attenuator errors
were present;
• jitter attenuator FIFO overflow errors – the number of jitter attenuator FIFO buffer
overflows;
• jitter attenuator FIFO underflow errors – the number of jitter attenuator FIFO buffer
underflows;
• seconds with jitter attenuator FIFO error(s) – seconds, during which jitter attenuator
FIFO buffer errors (overflows or underflows) were present;
• TFSC jerks – the number of TFSC errors (this error appears when the PCLK
synchronization source is unstable);
