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.
