Link counters
0 - counter of HDB3 encoding violations
0 - total HDB3 encoding violations
0 - receive errored seconds
0 - frame alignment signal errors
0 - seconds with CRC4 errors or unframed encoding violations
0 - total CRC4 errors (lights LERR)
0 - total unframed encoding violations (lights LERR)

The E1 link counters are as follows:
• counter of HDB3 encoding violations — number of HDB3 encoding violations (16
bit counter with saturation).
• total HDB3 encoding violations — total number of code violation (32 bit cycling
counter).
• receive errored seconds — time in seconds during which loss of signal or loss of
frame/multiframe synchronization have been encountered in E1 link.
• frame alignment signal errors — number of frame synchronization errors (FAS).
• seconds with CRC4 errors or unframed encoding violations — time in seconds dur-
ing which CRC4 errors or code violations have been encountered (for the Unframed
mode).
• total CRC4 errors — total number of CRC4 errors.
• total unframed encoding violations — total number of (for the Unframed mode).
• seconds with slip events — time in seconds during which slip events have been en-
countered.
• total slip full events — total number of overflows of the slip buffer.
• total slip empty events — total number of underflows of the slip buffer.
