Modem Setup
The Modem Setup menu is used to change the Modulation Type used for the ADSL connection. This setting
should only be changed if your service provider has given explicit instructions to change it.
Note
Do not change the (ADSL) Modulation type used unless you have been instructed to do
so. If this setting is not configured properly, the Router will not work.

If you are instructed by your ISP to change the Modulation type is used for your service, select the desired
modulation type and then click Apply. The modulation types available are T1413, G.DMT, GLITE and
MMODE. By default, the Router will automatically detect the modulation used; this setting is listed as MMODE
(Multi-mode).
Configure Connection 1 for PPPoA
PPP or Point-to-Point protocol is a standard method of establishing a network connection/session between
networked devices. Different forms of PPP include PPPoA and PPPoE (discussed below) involve an
authentication process that requires a username and password to gain access to the network. PPPoA (PPP over
ATM) as described in RFC 2364, is a method of using PPP on an ATM network. ATM is used for many types of
telecommunications services including ADSL.
To configure the WAN connection for PPPoA, perform the steps listed below. Some of the settings do not need
to be changed the first time the device is set up, but can be changed later if you choose.
