Encapsulation Select the method of encapsulation used by your ISP from the
drop-down list box. Choices vary depending on the mode you
select in the
Mode field.
If you select Bridge in the Mode field, select either PPPoA or
RFC 1483 .
If you select Routing in the Mode field, select PPPoA , RFC
1483 , ENET ENCAP or PPPoE .
Multiplexing Select the method of multiplexing used by your ISP from the
drop-down list. Choices are
VC or LLC .
By prior agreement, a protocol is assigned a specific virtual
circuit, for example, VC1 will carry IP. If you select VC, specify
separate VPI and VCI numbers for each protocol.
For LLC-based multiplexing or PPP encapsulation, one VC carries
multiple protocols with protocol identifying information being
contained in each packet header. In this case, only one set of VPI
and VCI numbers need be specified for all protocols.
VPI The valid range for the VPI is 0 to 255. Enter the VPI assigned to
you.
VCI The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for
local management of ATM traffic). Enter the VCI assigned to you.
IP Address This option is available if you select Routing in the Mode field.
A static IP address is a fixed IP that your ISP gives you. A
dynamic IP address is not fixed; the ISP assigns you a different
one each time you connect to the Internet.
If you use the encapsulation type except RFC 1483 , select
Obtain an IP Address Automatically when you have a
dynamic IP address; otherwise select Static IP Address and
type your ISP assigned IP address in the IP Address field below.
If you use RFC 1483 , enter the IP address given by your ISP in
the IP Address field.
Subnet Mask This option is available if you select ENET ENCAP in the
Encapsulation field.
Enter a subnet mask in dotted decimal notation.
ENET ENCAP
Gateway
This option is available if you select ENET ENCAP in the
Encapsulation field.
Specify a gateway IP address (supplied by your ISP).
Connection
Nailed-Up Connection Select

up all the time. The ZyXEL Device will try to bring up the
connection automatically if it is disconnected.
Connect on Demand Select Connect on Demand when you don't want the connection
up all the time and specify an idle time-out in the Max Idle
Timeout field.
