Cisco Cisco MGX-FRSM-HS2 B Serial Frame Service Module

The service module contains onboard BERT circuitry. With this circuitry present, the software can send 
and detect a programmable pattern that is compliant with CCITT/ITU pseudorandom and repetitive test 
patterns. BERT allows you to test cables and signal problems in the field.

When a BERT is running, your system expects to receive the same pattern that it is sending. To help 
ensure this, two common options are available.

Use a loopback somewhere in the link or network.

Configure remote testing equipment to send the same BERT pattern at the same time.

See the bert pattern (t3/e3) command in 

 for instructions 

on how to run BERT and check the results.

Use the show version command to determine whether the router recognized the T3/E3 card and was able 
to initialize the card properly. The show version command lists the hardware interfaces and controllers 
present in the router. You should find “1 Subrate T3/E3 port(s)” as shown in the following example.
