SDH Results - Error / Alarm
The Results Error / Alarm screen contains the following options:
•
Scan - Select Scan to access a quick summary of incoming errors and alarms. It
is effective in identifying a general area to investigate when error or alarm activity
is detected. This function displays a list of received errors and alarms. For
alarms, the duration is reported as a count in seconds. For errors, an error count
is reported.
When no activity is occurring, the screen displays "No Errors or Alarms"
•
Errors - The unit can monitor and report errors on the incoming SDH signal. The
Errors function provides a detailed analysis of the incoming error as described
below. The reported errors are a result of incoming errors that are generated by
the SDH network, or errors that are intentionally generated by the system when it
is used in a loopback environment.
The following SDH errors can be monitored:
BPV (Bi-Polar Violation, for STM-0e
only)
