Description Use the activate command to activate an ADSL interface.

Use the undo activate command to deactivate an ADSL interface.

By default, an ADSL interface is active.

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 communication connection is set up between the two parties for service transmission.

Contrary to activation, deactivation tears down the communication connection between the two parties. To transmit services, you need to re-activate the interface.

The commands here are intended for test and diagnosis purposes. Unlike the shutdown and undo shutdown commands, the commands here only affects a G.SHDSL line.

Since an ADSL interface is always on, it transits to the active state automatically at boot and remains in this state as long as the link is in good condition. The router tests the performance of the line regularly. Once it finds that the line performance is deteriorating, it automatically deactivates, retrains, and then reactivates the line.

Example # Activate ADSL interface 2/0.

<Sysname> system-view

[Sysname] interface atm 2/0

[Sysname-Atm2/0] activate
