The modem configuration can be viewed and modified through the console
which is accessible through the RS-232 serial connection. To use the serial
interface, a straight-through cable is needed between the modem and a terminal
(could be a PC running a terminal emulation package).
The PHY can be configured to attempt the layer 1 connection in one of the
following modes:
•
••
•T1.413
•
••
•G.Lite
•
••
•G.dmt
This is configured by setting the BUN attribute AdslMode with the following
console command:
