The total number of error bits received, and the total number of bits received are available for analysis. You
can select the testing period from 1 minute to 24 hours, and you can also retrieve the error statistics anytime
during the BERT test.
BERT is supported in two directions:
• Line - supports BERT in TDM direction
• System - supports BERT in PSN direction
Note
Before starting system side BERT, you must configure CEM. When the BERT is configured towards
system direction, it internally loopbacks the TDM side.
Configuring BERT
Before you run BERT test, you must configure card type and controller.
To run a BERT on T1 interface, perform the following tasks in global configuration mode.
enable
configure terminal
controller t1 0/4/0
bert pattern 2^11 interval 5 direction [line | system]
exit
Verifying BERT Configuration for SAToP
Use the following command to verify the BERT configuration for T1 interfaces:
Router# show controllers t1 0/4/0
T1 0/4/1 is up.
Applique type is
