Clear Alarm Log
Clear all entries in the alarm log by typing the
Clear Alarm Log (C A L)
command.
Display Status
The
Display Status (D S)
command displays the current alarm condition of the E1 link
as well as the on-hook or off-hook status of each of the 30 ports of the LEI. Entering this
command causes a screen similar to
Figure 60: Display Status (D S) screen
on page 237 to
appear.
The Pause command can be used to display a full screen at a time, by entering
D S P
. If there
is more than one screen, the MMI scrolls until the screen is full, then stops. When ready to see
the next screen, press any key. The display shows one more screen, and stops again. This
continues until the entire E1 link is reported on.

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.
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:
• Errored seconds are seconds in which one or more CRC-4 / BPV errors, 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.
