Performance counters and reporting
The MMI monitors the performance of the E1 link according to several
performance criteria including errored, bursty, unavailable, loss-of-frame and
frame-slip seconds. It registers the performance of these criteria by reading
their status every second and counting their results. These counts are
accumulated for an hour, then reset to 0. Previous hour count results are
maintained for each of the previous 24 hours.

accumulated for an hour, then reset to 0. Previous hour count results are

The LEI counts CRC-4 errors when CRC-4 is enabled and Bipolar Violations
(BPV) when CRC-4 is disabled. The performance criteria for which these
counts are maintained as follows:
(BPV) when CRC-4 is disabled. The performance criteria for which these
counts are maintained as follows:

Errored seconds are seconds in which one or more CRC-4 / BPV errors,
or one or more out-of-frame errors in one second.
or one or more out-of-frame errors in one second.
•
Bursty seconds are seconds in which more than one and less than 320
CRC-4 / BPV errors in a second.

Severely errored seconds are seconds in which more than
320 CRC-4 / BPV errors, or one or more out-of-frames in a second.
320 CRC-4 / BPV errors, or one or more out-of-frames in a second.

Unavailable seconds are seconds in which unavailable state starts with 10
consecutive severely errored seconds and ends with 10 consecutive
non-severely errored seconds (excluding the final 10 non-severely
errored seconds).
