Cisco T1 User Manual

• The system side BERT is not supported on partial timeslots. For the system side BERT, use full timeslots.
Configuring BERT for CESoPSN
Before You Begin
Before you run BERT test, you must configure card type and controller.
To run a BERT on T1/E1 interface for CESoPSN, perform the following tasks in global configuration mode.
enable
configure terminal
controller t1/e1 0/1/1
bert pattern 2^11 interval 5 direction line/system timeslots value speed
exit
To terminate a BERT test during the specified test period, use the no bert command.
Note
Verifying BERT Configuration for CESoPSN
Use the following command to verify the BERT configuration for CESoPSN on T1 interfaces:
Router# show controllers t1 0/4/32 brief
T1 0/4/32 is up
Applique type is NCS4200-48T1E1-CE
Cablelength is short 110
