Performing a Trouble Scan
When first connecting to the network it can be useful to have an indication of any
problems that exist before starting testing. In the OmniBER 720 this feature is
provided by Trouble Scan.
All possible error sources and alarms are scanned simultaneously. If any error
counts are not zero then these are displayed. Up to 4 non-zero error counts are
displayed in priority order.
If all error counts are zero and any alarms are detected "ALARMS DETECTED" is
displayed.
and the alarm led's can be used to determine which alarms were detected.
SHOW
If no alarms are detected and all error counts are zero then "NO TROUBLE" is
displayed.
