ADSL WAN Connections
ADSL Modules for the ProCurve Secure Router
Activating the ADSL Interface
By default, all interfaces on the ProCurve Secure Router are shutdown. You
must activate the ADSL interface. From the ADSL interface configuration
mode context, enter:
ProCurve(config-adsl 1/1)# no shutdown
A message is displayed at the CLI, indicating that the interface is now admin-
istratively up. Messages such as this are displayed by default. To disable these
messages, enter the following command from the enable mode context:
ProCurve# no events
To enable these messages again, enter:
ProCurve# events
Defining the Training Mode
Like other ADSL routers and modems, the ProCurve Secure Router must go
through a training phase. During the training phase, the ADSL interface and
the DSLAM evaluate the quality of the line and identify the best way to use the
available bandwidth to achieve the highest transmission rate possible.
After the training phase, the ProCurve Secure Router and the DSLAM establish
an ADSL connection and exchange Physical Layer signaling. This phase of the
connection is called showtime. Although the two devices have established a
physical connection, they have not yet begun to exchange ATM cells or to
communicate at the Data Link Layer.
You must select the standard that the ADSL interface uses during the training
mode. Table 7-3 lists the training mode options, the standards on which each
one is based, and a brief description.
