A G.SHDSL interface must be activated before it can transmit services.
Activation refers to the training between the G.SHDSL end and the STU-C end.
Based on such preset items 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. When the interface is
deactivated, no communication link exists, so you must activate the interface
again,if you want to transmit services over it.
The commands are mainly used in link testing and fault diagnosis.
The difference between the
activate/undo activate
command and the
shutdown/undo shutdown
command is that the former only functions on the
G.SHDSL interface.
A G.SHDSL interface is always on so it will enter the active state as long as the
link is functional. The router supports timed loop detection, so the G.SHDSL
interface is activated when the link performance has deteriorated.
Example
Deactivate the G.SHDSL interface.
