Description A G.SHDSL interface must be activated before it can transmit services. Activation
refers to the training between the G.SHDSL office end and the STU-C end, based on
preset items such as SHDSL standard, channel mode, upstream and downstream rates
and SNR margin in link template. The training process detects line distance and
performance, negotiates between two ends and determines if the interface can run
normally under such condition. If the training succeeds, a communication link is set
up between two ends and the interface is activated, on which services can be
transferred. Upon deactivation of the interface, the office end and the remote device
is disconnected. To transmit services over the interface again, you must activate it.
The commands are mainly used in link testing and fault diagnosis.
The activate/undo activate command differs from the shutdown/undo
shutdown command in that it only functions on the G.SHDSL interface.
Since a G.SHDSL interface is always on, it enters the active state automatically and
remain in this state as long as the link is in good condition. The router supports timed
loop detection, so the G.SHDSL interface will be activated again when the link
performance is deteriorated.
