Description Before an ADSL interface can operate services, you must activate it. “ACTIVATE” in
this particular context refers to the training conducted between the ADSL central
office and the remote ATU-R. The activation procedure is 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 above 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
interface activation. This connection will disappear upon the deactivation of the ADSL
interface. To transport new services, you must re-activate the interface.
This command is used to activate/deactivate an ADSL line manually for the purpose of
testing and troubleshooting.
The commands activate/undo activate and shutdown/undo shutdown
are different in the sense that the former can only take effect on ADSL lines.
You should note that ADSL is always on line, which is different from DCC. Therefore,
after the device is booted, the ADSL interface will automatically enable the activation
task and enter the active state. It will stay active so long as the line is in good
condition. The router tests the line performance at a regular interval and will
automatically deactivate the line and make a new training and re-activation once it
finds out that the line performance has been deteriorated.
