Encapsulation Select the method of encapsulation used by your ISP from the drop-down list

box. Choices are PPPoA, RFC 1483, ENET ENCAP or PPPoE.

User Name (PPPoA and PPPoE encapsulation only) Enter the user name exactly as your ISP

assigned. If assigned a name in the form user@domain where domain identifies

a service name, then enter both components exactly as given.

Password (PPPoA and PPPoE encapsulation only) Enter the password associated with the

user name above.

Service Name (PPPoE only) Type the name of your PPPoE service here.

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.

If you use RFC 1483, enter the IP address given by your ISP in the IP

Address field.
