Cisco ASR 1000 Series Software Configuration Guide

Changing a Channel Group Configuration
To alter the configuration of an existing channel group, the channel group needs to be removed first using the
no form of the channel-group command. To remove an existing channel group, use the following commands:
SUMMARY STEPS
1.
Router# configure terminal
2.
Router(config)# interface serial slot/subslot/port
3.
Router(config-controller)# no channel-group t1 t1-number
DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.Router# configure terminal
Step 1
Select the controller to configure and enters controller configuration
mode, where:
Router(config)# interface serial
slot/subslot/port
Step 2
Example:
• slot/subslot/port —Specifies the location of the controller.
For addressing information, refer to the Specifying the Physical Address
for Controller and Interface Configuration, on page 292.
Selects the channel group you want to remove, where:Router(config-controller)# no channel-group
t1 t1-number
Step 3
• t1-number—Channel-group number.
Configuring BERT
BERT (Bit-Error Rate Testing) is used for analyzing quality and for problem resolution of digital transmission
equipments. BERT tests the quality of an interface by directly comparing a pseudorandom or repetitive test
pattern with an identical locally generated test pattern.
The BERT operation is data-intensive. Regular data cannot flow on the path while the test is in progress. The
path is reported to be in alarm state when BERT is in progress and restored to a normal state after BERT has
been terminated.
BERT Test Configuration Guidelines
When configuring BERT on the 1-Port Channelized OC-3/STM-1 SPA or 1-Port Channelized OC-12/STM-4
SPA, consider the following guidelines:
•
Only DS1/T1 and DS3/T3 paths are supported on the 1-Port Channelized OC-12/STM-4 SPA.
•
A maximum of 27 concurrent tests across all paths on the SPA is supported.
