Reported
Local indications –
Cause In the incoming SHDSL signal, the number of CRC errors per second exceeds
a predefined error threshold.
Actions Check SHDSL connection on attenuation and crosstalk.
Note(s) These bit error thresholds are defined:
• More than 37 CRC errors per second lead to an SDSLcDEG alarm.
• More than 163 CRC errors per second lead to an SDSLcEXC alarm.
