5.2.3.2 PPPoA Connection Setup
PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM cells
which are carried over the DSL line. PPP or Point-to-Point protocol is a method of establishing a
network connection / session between network hosts. It usually provides a mechanism of
authenticating users. LLC and VC are two different methods of encapsulating the PPP packet.
Contact your ISP to make sure which encapsulation is being supported.
By selecting PPPoA, you are forcing your Wireless ADSL Router to terminate the PPPoA
connection. The advantage is that the PPPoA termination is done within the Wireless ADSL
Router and not on your PC; this frees up your PC resources and allows multiple users to utilize
the PPPoA connection.
To configure the gateway for PPPoA, click on Setup and then click on
New Connection . The
default PPPoE connection setup is displayed. At the Type field select PPPoA and the PPPoA
connection setup page is displayed; figure 15 illustrates a typical PPPoA configuration. Give your
PPPoA connection a unique name; the name must not have spaces and cannot begin with
numbers. In this case the unique name is called
PPPoA1 . Select the encapsulation type (LLC or
VC); if you are not sure just use the default mode. Select the VPI and VCI settings; your DSL
service provider or your ISP will supply these; in this case the DSL service provider is using
0,100 . Also select the quality of service (QOS); leave the default value if you are unsure or the
ISP did not provide this information.
Following is a description of the different options:
a. Username: The username for the PPPoA access; this is provided by your DSL
service provider or your ISP.
b. Password: The password for the PPPoA access; this is provided by your DSL service
provider or your ISP.
c. On-Demand: Enables on-demand mode. The connection will disconnect if no activity
is detected after the specified idle timeout value.
d. Idle Timeout: Specifies that PPPoA connection should disconnect if the link has no
activity detected for n seconds. This field is used in conjunction with the On-Demand
feature. To ensure that the link is always active, enter a 0 in this field.
e. Keep Alive: When on-demand option is not enable, this value specifies the time to
wait without being connected to your provider before terminating the connection. To
ensure that the link is always active, enter a 0 in this field.
