Usage guidelines
An ADSL interface must be activated before it can transmit services. Activation refers to training between
ADSL office end and ATU-R end. During this process, the two parties examine line distance and
conditions against the line configuration template (which defines the ADSL criteria, channel mode, uplink
and downlink speeds, and noise tolerance) and attempt to reach an agreement. If the training succeeds,
a connection is set up between the two parties for service transmission.
Deactivation tears down the connection between the two parties. To transmit services, you must
re-activate the interface.
The active command and its undo form are intended for test and diagnosis purposes. Unlike the
shutdown and undo shutdown commands, they only affect the ADSL line.
Because an ADSL interface is always on, it transits to the active state automatically at boot and remains
active as long as the link is in good condition. The router regularly tests the performance of the line. If it
finds that the line performance is deteriorating, it automatically deactivates, retrains, and then reactivates
the line.
