Select User-Defined if you have the IP address of a DNS server. Enter the
DNS server's IP address in the field to the right. If you chose User-Defined,
but leave the IP address set to 0.0.0.0, User-Defined changes to None after
you click Apply. If you set a second choice to User-Defined, and enter the
same IP address, the second User-Defined changes to None after you click
Apply.
Select None if you do not want to configure DNS servers. You must have
another DNS server on your LAN, or else the computers must have their DNS
server addresses manually configured. If you do not configure a DNS server,
you must know the IP address of a computer in order to access it.

Demand time and specify an idle time-out in the Max Idle Timeout field.
Max Idle Timeout Specify an idle time-out in the Max Idle Timeout field when you select
Connect on Demand. The default setting is 0, which means the Internet
session will not timeout.
Service Type
Service Mode Select 2-wire, 4-wire or 2wire-2line mode for the DSL connection. This is
depends on the network configuration you want to set up and the phone lines
you use. Service mode affects the maximum speed of the connection. In 2-
wire mode, the maximum data rate is up to 5.69 Mbps, while in 4-wire mode,
the maximum data rate is up to 11.38 Mbps. In 2wire-2line mode the
maximum data rate is 5.69 Mbps for each line. See
for more information on configuring 2wire-2line mode.
Service Type Indicate whether the P-79X is the server or the client in the DSL connection.
Select Server if this P-79X is the server in a point-to-point application.
Otherwise, select Client. This field is not configurable if you select 2wire-
2line mode because the ZyXEL Device is automatically set to Server.
Enable Rate This field is enabled if Service Type is Server. Indicate whether or not the P-
Adaption 79X can adjust the speed of its connection to that of the other device.
Transfer Max Rate This field is enabled if Service Type is Server. Set the maximum rate at which
(Kbps) the P-79X sends and receives information. The actual transfer rate will be
between this value and the minimum transfer rate you configure.
When you select 4-wire in the Service Mode field, then the transfer rate you
set here is doubled. For example, select 5696 Kbps to configure a maximum
transfer rate of 11392 Kbps.
