Verifying VT1.5-T1 BERT Configuration for CESoPSN
Use show controller sonet command to verify BERT configuration in mode VT 1.5:
Router# show controller sonet 0/5/0.2/2/3 | sec BERT
BERT running on timeslots 1,2,3,4,5,6,7,8,
BERT test result (running)
Test Pattern : 2^11, Status : Sync, Sync Detected : 1
Interval : 1 minute(s), Time Remain : 00:00:43
Bit Errors (since BERT started): 0 bits,
Bits Received (since BERT started): 8 Mbits
Bit Errors (since last sync): 0 bits
Bits Received (since last sync): 8 Mbits

Configuring CT3-T1 mode BERT for CESoPSN
To configure T1 CT3 mode BERT, use the following commands:
controller mediatype 0/5/0
mode sonet
controller sonet 0/5/0
rate oc3
sts-1 1
mode ct3
t1 4 bert timeslots 1 pattern 2^15 interval 1 direction
Verifying CT3-T1 mode BERT for CESoPSN
Use show controller sonet command to verify BERT configuration in mode CT3:
