Fault Isolation/Correction Using Mmi Maintenance Commands; Checking The Carrier Performance Status - Avaya Communication Server 1000M Single Group Manual

Fault isolation/correction using MMI maintenance commands

You can perform testing and troubleshooting of the Mini-Carrier Remote from a local or a
remote MMI terminal or TTY by typing MMI commands on the terminal without loading system
diagnostic programs (overlays).
These commands provide current equipment status, invoke card testing, check equipment
performance, and print messages from log files.

Checking the carrier performance status

The Remote Mini-carrier Interface card can display carrier performance information for the
current hour and for the last 24 hours. The data and total errors are shown separately in the
report for both the local and the remote site. The report displays the bit error rate, loss of frame
count, loss of signal, alarm indication count, and frame slip count. To obtain the information for
the current hour, execute the DISPLAY PERFORMANCE (D P) command for the near-end or
the DISPLAY PERFORMANCE DISTANT (D P D) command for the distant-end carrier
performance status using the MMI terminal.
To obtain the carrier link performance status:
1. Log in on the maintenance terminal.
2. To display a similar report for the 24-hour period listed in 1 hour increments enter
Mini-Carrier Remote Fundamentals
At the > prompt, type D P and press the Enter key .
The report displays carrier error counts monitored over 17 minutes for carrier 0. An
example of the on-screen display for this command may be seen in
DISPLAY PERFORMANCE (D P) screen
Note:
The performance measurements indicate the service quality of the carrier link
you selected. Ideally all errored second categories should be 0. If a number other
than 0 appears in one or more columns, it indicates momentary or continuous
problem on the link. If the numbers are small and the carrier is not in alarm state,
the errors may have been temporary and the link may continue to operate within
the specified thresholds. To clear the cumulative error counter, enter the CLEAR
ERROR (C E) or CLEAR ERROR DISTANT (C E D) command, as appropriate.
Clearing these errors does not affect the errored second counters.
the DISPLAY HISTORY (D H) command for the near end, or DISPLAY HISTORY
DISTANT (D H D) for the distant end. The screen displayed is similar to
