commands page, click on Save All.
4.4.1.2 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 pro-
tocol is a method of establishing a network connec-
tion / session between network hosts. It usually pro-
vides 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 ADSL
Router to terminate the PPPoA connection. The
advantage is that the PPPoA termination is done
within the 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 5 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 connec-
tion should disconnect if the link has no acti-
vity 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.
f.) Set Route: Specify this connection as the
default-route.
g.) MRU: Maximum Receive Unit the DSL con-
nection can receive. It is a negotiated value
that asks the provider to send packets of no
more than n bytes. The maximum specified
value is 1500 although some DSL/ISP provi-
ders require a larger value. The minimum
MRU value is 128.
