LABEL DESCRIPTION
Multiplex Select the method of multiplexing used by your ISP from the drop-down list. Choices
are
VC-Mux or LLC .
IPv6/IPv4 Dual Stack If you select IPv4/IPv6 , the Device can connect to both IPv4 and IPv6 networks and
choose the protocol for applications according to the address type. If you select IPv4
or IPv6 the Device will operate in IPv4 or IPv6 mode.
PPP Authentication The Device supports PAP (Password Authentication Protocol) and CHAP (Challenge
Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP is
readily available on more platforms.
Use the drop-down list box to select an authentication protocol for outgoing calls.
Options are:
AUTO - Your Device accepts either CHAP or PAP when requested by this remote node.
CHAP - Your Device accepts CHAP only.
PAP - Your Device accepts PAP only.
Virtual Circuit ID VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual
circuit. Refer to the appendix for more information.
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 Router 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.

otherwise select Static IP Address and type your ISP assigned IP address in the IP
Address and Gateway IP Address fields (supplied by your ISP) below.
IPv6 Rapid
Deployment This is available only when you select IPv4 in the IPv6/IPv4 Dual Stack field. By
enabling the IPv6 Rapid Deployment function, the Device uses an ISP’s IPv6 address
prefix instead of the 2002::/48 prefix. The operational domain of 6RD is limited to
and controlled by the ISP’s network. 6RD hosts are ensured to be reachable from all
native IPv6 addresses as 6RD only uses relay servers within control of the ISP.
Enable Select this option to enable IPv6 Rapid Deployment.
Mode Select Auto or Manual mode. If you select Manual , enter the tunneling relay
server's IPv4 address in the field below.
Relay Server Enter the tunneling relay server's IPv4 address in this field.

connected router’s Router Advertisement (RA) to generate an IPv6 address.
