5 COMMANDS

activate

Syntax activate

undo activate

View ATM (G.SHDSL) interface view

Parameter None

Description Use the activate command to activate the G.SHDSL interface.

Use the undo activate command to deactivate the G.SHDSL interface.

By default, a G.SHDSL interface is active.

A G.SHDSL interface must be activated before it can transmit services. Activation refers to training between the G.SHDSL office end and the STU-C 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.

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 affect a G.SHDSL line.

Since a G.SHDSL 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 Atm 5/0.

<Sysname> system-view

[Sysname] interface atm 5/0

[Sysname-Atm5/0] activate
