Description
Using the activate command, you can activate an ADSL interface. Using the undo
activate command, you can deactivate an ADSL interface.
By default, the ADSL interface is active.
Before an ADSL port can operate services, you must activate it. “ACTIVATE” in this
particular context refers to the training conducted between an ADSL central office
and a remote ATU-R. The activation procedure will be specified in compliance with
the ADSL standard, channel mode, uplink and downlink speeds, and the noise
tolerance specified in the line configuration template. It will test the line distance
and state, make the central office and the remote device make negotiation, and
confirm whether the normal operation is allowed in the these conditions. If the
training succeeds, the central office and the remote device can set up a
communication connection for transporting services between them. This process is
also called port activation. This connection will disappear upon the deactivation of
the ADSL port. To transport new services, you must re-activate the port.
This command is used to manually activate/deactivate an ADSL line for the
purpose of testing and troubleshooting.
The commands activate/undo activate and shutdown/undo shutdown are different
because the former can only take effect on ADSL lines.
You should note that ADSL is always online, which is different from DCC.
Therefore, after the device is booted, the ADSL interface will automatically enable
