This value indicates the number of Severely Errored Seconds in the E1 data stream.
Possible Cause

within that second.
• When CRC is disabled, an errored second is listed when more than 850 CVs occur within
that second.
Recommended Actions:
1. Check the E1 signal with a BERT test set to determine origin of error.
