Section 4 Troubleshooting

SES Values in E1A or E1B Performance History Menu

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

Possible Cause

•

When CRC is enabled, a severely errored second is listed when more than 805 CRCs occur
within that second.

•

When CRC is disabled

an errored second is listed when more than 850 CVs occur within

that second.

Recommended Actions:

Check the E1 signal with a BERT test set to determine origin of error.
