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.

Line

Select the DSL connection you want the ZyXEL Device to use for outgoing 

traffic. 

IP Address

These fields only appear if the Mode is Routing.
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. ‘

on Demand. The default setting is 0, which means the Internet session will not 

timeout.
