DISPLAY ALARM (D A) screen
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.
Step
To obtain the carrier link performance status:
1
Action
Log in on the maintenance terminal.
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
PERFORMANCE (D P) screen" (page
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.
