5.5.2 Configuring More Connections Advanced Setup
Use this screen to edit your ZyXEL Device's advanced WAN settings. Click the Advanced
Setup button in the More Connections Edit screen. The screen appears as shown.
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 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. ‘
