How to Configure BERT

4.no bert pattern pattern interval time

DETAILED STEPS

 

Command

Purpose

 

 

 

Step 1

enable

Enables privileged EXEC mode.

 

 

Enter your password if prompted.

 

Example:

 

 

Router> enable

 

 

 

 

Step 2

configure terminal

Enters global configuration mode.

 

Example:

 

 

Router# configure terminal

 

 

 

 

Step 3

controller {t1 e1} slot/port

Selects a T1 or E1 controller and enters controller configuration

 

 

mode.

 

Example:

 

 

Router(config)# controller T1 0/5

 

 

 

 

Step 4

no bert pattern pattern interval time

Terminates the BER test running on the specified T1 or E1 line.

 

Example:

 

 

Router(config-controller)# no bert pattern

 

 

 

 

Verifying BERT on a T1/E1 Controller

To verify that BERT is running on a T1/E1 controller, enter the show controllers command at any time during the test.

 

 

 

Router# show controllers

E1 0/9 is

up.

 

 

 

 

 

Applique type is Channelized E1 - balanced
