Usage guidelines
A G.SHDSL interface on a CPE must be activated before it can transmit services.
Activation refers to the handshake training and information exchange process between the CO
equipment and the CPE. During this process, the two parties examine the line distance and conditions
against the line configuration template of the CO equipment. The template defines the SHDSL criteria,
channel mode, uplink and downlink speeds, and noise tolerance. The parties attempt to reach an
agreement. If the activation succeeds, a connection is set up between the two parties for service
transmission.
During the parameter negotiation process for line activation, the CO equipment provides most
parameters for the CPE. A line activation process starts from line negotiation until the line comes up.
Typically the activation process lasts for 30 seconds.
Deactivation tears down the connection between the two parties. To transmit services, you must
re-activate the interface.
Because a G.SHDSL interface is always on, it transits to the active state automatically at startup and
remains active as long as the link is in good condition. The router regularly tests the performance of the
line. If the router finds that the line performance is deteriorating, it automatically deactivates, retrains,
and then reactivates the line.
This command enables you to manually activate or deactivate a G.SHDSL interface. It is intended for test
and troubleshooting uses.
