D-Link DSL-2544N User Manual 20
If you select the
PPP over Ethernet (PPPoE)
or
PPP over ATM (PPPoA)
as the
protocol
, the following page appears.

PPP Username/Password: The correct user name and password that your
ISP provides to you.

Authentication Method: There are four methods available in the
drop-down list: AUTO, PAP, CHAP, or MSCHAP . Usually, you can select
AUTO.

Dial on mode:

AlwaysOn
: If you select it, the system automatically establishes a
connection. If the network is disconnected because of external factors when
you are using the Internet access service, the system tries connection every
certain time (for example, 10 seconds) until the connection is established. If
you pay for Internet access in the monthly fee mode, you are recommended
to use this connection mode.
OnDemand : If you select it, the system automatically establishes a
connection when a network access request from the LAN is received. If no
network access request is sent from the LAN within the set time of Idle
Timeout , the system automatically interrupts the connection. If you pay for
Internet access by time, you are recommended to use this connection
mode, which effectively saves the expense of Internet access.
Manual:
If you select it, you need to manually set dialup connection after
startup. If this function is enabled, you need to enter the idle timeout time.
Within the preset minutes, if the modem does not detect the flow of the user
continuously, the modem automatically stops the PPPoE connection. Once
it detects the flow (like access to a webpage), the modem restarts the
PPPoE dialup.

MRU Size: Maximum Receive Unit. The Maximum Receive Unit(MRU)
option must not be negotiated to a size larger than 1492, unless both the
PPPoE client and server have indicated the ability to support a larger MRU
in the PPPoE Discovery Stage.

MTU Size: Maximum Transmission Unit. Sometimes, you must modify this
function to access network successfully.

Keep Alive:
Enable or disable the PPPoE dial-up to keep alive.
