Octal-Port DMT ATU-C Line Card
dmt rate-adaptation enable
DMT rate adaptation monitors upstream and downstream DMT ports for signal-to-noise ratio (SNR)
margins during specified time intervals. If an unacceptable SNR margin is detected, the port is retrained
at a lower bit rate to improve the SNR margins. To enable rate adaptation on a DMT port, use the
dmt rate-adaptation enable command at the DSL profile configuration prompt. To disable dmt rate
adaptation, use the no form of the command.
This command has no arguments or keywords.
Defaults Enabling dmt rate-adaptation configures the commands dmt rate-adaptation interval and
dmt rate-adaptation margin with their default values. For information on the default values of
dmt rate-adaptation interval and dmt rate-adaptation margin see the
