6. Select the quality of service (QOS). Leave the default value if your ISP did not provide this
information.
Following is a description of the different options:
Username: The username for the PPPoA access; this is provided by your DSL service provider or your
ISP.
Password: The password for the PPPoA access; this is provided by your DSL service provider or your
ISP.
On-Demand: Enables on-demand mode. The connection will disconnect if no activity is detected after the
specified idle timeout value.
Idle Timeout: Specifies that PPPoA connection should disconnect if the link has no activity detected for
the specified number of seconds. This field is used in conjunction with the On-Demand feature. To
disable Idle Timeout and ensure that the link is always active, enter a 0 in this field.
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.
Maxfail: As long as a DSL connection is established, the router will attempt to establish a PPPoA
connection. If after n consecutive failed connection attempts the router will wait for some random time
before trying to establish the connection again. A value of 0 means no limit.
Set Route: Specify this connection as the default-route.
MRU: Maximum Receive Unit the DSL connection can receive. It is a negotiated value that asks the
provider to send packets of no more than the specified number of bytes. The maximum specified value is
1500 although some DSL/ISP providers require a larger value. The minimum MRU value is 128.
Debug: Enables PPPoA connection debugging facilities. Debugging is talked about later.
