Restrictions for SONET BERT on CESoPSN
Modes
SONET—AU-3 Mapping—AU3_T1
SONET—AU-4 Mapping—AU4_E1
Restrictions for SONET BERT on CESoPSN
• In the system-level BERT for CESoPSN, only the full timeslot is supported and the fractional timeslot
• In the BERT timeslot configuration, the timeslot should be same as the one provided in the CEM
• The BERT is supported either on the NxDS0 or DS1 side but not together.
