• 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).
• Loss-of-frame seconds are seconds in which loss-of-frame or loss-of-signal conditions
exist for three consecutive seconds.
• Frame slip seconds are seconds in which one or more frame slips occur.
The MMI also maintains an overall error counter which is the sum of all errors counted for the
performance criteria listed above. The error counter can only be cleared by entering the
Clear
Error (C E)
command. It stops counting at 65,000. The error counter provides an easy
method to determine if an alarm condition is corrected. Clear the error counter, wait a few
minutes, and display the performance to see if any errors occurred because the counter was
cleared.
The MMI display reports on these performance counters through the
Display Performance
(D P)
or the
Display History (D H)
commands.
Display Performance
Entering the
Display Performance (D P)
command displays performance counters for
the past hour. A screen similar to
Figure 61: Display Performance (D P) screen
on page 238
appears.
Figure 61: Display Performance (D P) screen
Each column, except the error counter, indicates the number of errors in the current hour and
is reset to zero every hour on the hour. Just before the performance counters are reset to zero,
the values are put into the history log.
The error counter indicates the number of errors because the error counter was cleared.
The Pause command can be used to display a full screen at a time, by entering
D P P
. If more
than one screen is to be displayed, 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 display is shown.
