Chapter 4 Configuring Digital Subscriber Lines
Setting DSL Profile Parameters
If the actual framing mode used is the mode the ATU-C port requested, or if the ATU-R CPE does not
support the ATU-C choice, then the highest mode the ATU-R does support is used.
Example
This example sets the overhead framing mode in the default profile to mode3 and displays the results:
DSLAM# configure terminal
DSLAM(config)# dsl-profile default
DSLAM(cfg-dsl-profile)# dmt overhead-framing mode3
DSLAM(cfg-dsl-profile)# end
DSLAM# show dsl profile
dsl profile default:
Link Traps Enabled: NO
Alarms Enabled: NO
ATM Payload Scrambling: Enabled
