Setting your ISP Connection Type to PPPoE or PPPoA
PPPoE (Point-to-Point Protocol over Ethernet) is the standard method of con-
necting networked devices. It requires a user name and password to access
the network of your ISP for connecting to the Internet. PPPoA (PPP over ATM)
is similar to PPPoE, but is mostly implemented in the UK. Select PPPoE or PP-
PoA and then set the following options:
1. Multiplexing - Select as supplied by your ISP. VC-MUX: PPPoA Virtual Circuit
Multiplexer (null encapsulation) allows only one protocol running per virtual
circuit with fewer overheads. LLC: PPPoA Logical Link Control allows multiple
protocols running over one virtual circuit (more overhead).
2.Virtual Circuit - Enter your Virtual Path Identifier (VPI) and Virtual Circuit
Identifier (VCI) parameter here. (Assigned by your ISP).
3. User Name - Enter the user name. (Assigned by your ISP).
4. Password - Enter your password. (Assigned by your ISP).
5. Connect on Demand - Click this option if you want your Modem Router to
connect to your ISP when a connection is needed, and to disconnect when
the line to your ISP has been idle for a given amount of time. Connection and
disconnection are automatic. You can also adjust the maximum idle time; the
default setting is 20 minutes.
6. Keep Alive - Click this option if you want to maintain the connnection to
your ISP all the time. If the link goes down for a given number of seconds (the
"redial period"), the Modem Router will automatically try to re-establish it.
The default redial period is 20 seconds.
Setting your Connection Type to RFC 1483 Bridged/Routed
This connection method bridges your network and your ISP's network
together. The Router will obtain an IP address automatically from your ISP's
DHCP server.
1. Multiplexing - Select LLC or VC MUX.
2. VPI/VCI - Enter your Virtual Path Identifier (VPI) and Virtual Circuit Identifier
(VCI) parameters here. These identifiers are assigned by your ISP.
Setting your Connection Type to Bridge Mode Only (Disable Internet
Sharing)
In this mode, the Router simply acts as a bridge passing packets across the
DSL port. It requires additional software to be installed on your computers in
order to access the Internet.
