7.3 Technical Reference

The following section contains additional technical information about the P-79X features described
in this chapter.
Encapsulation
Be sure to use the encapsulation method required by your ISP. The P-79X can work in bridge mode
or routing mode. When the P-79X is in routing mode, it supports the following methods.
IP over Ethernet
IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an
Ethernet network, without using PPP encapsulation. They are routed between the Ethernet interface
and the WAN interface and then formatted so that they can be understood in a bridged
environment. For instance, it encapsulates routed Ethernet frames into bridged Ethernet cells.
PPP over Ethernet (PPPoE)
Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing functionality in a
manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how
a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.)
connection.

DESCRIPTION
A PIN (Personal Identification Number) code is a key to a 3G card. Without the PIN code,
you cannot use the 3G card.
If your ISP enabled PIN code authentication, enter the 4-digit PIN code (0000 for example)
provided by your ISP. If you enter the PIN code incorrectly, the 3G card may be blocked by
your ISP and you cannot use the account to access the Internet.
If your ISP disabled PIN code authentication, leave this field blank.
Specify the time interval (in minutes) for checking whether the 3G connection is valid or
not.
Specify the DNS server address for checking the 3G connection status.
Select On to enable the authentication. Otherwise, select Off.
This is available only when you select On in the Auth Mode field.
Type the user name (of up to 64 ASCII printable characters) given to you by your service
provider.
This is available only when you select On in the Auth Mode field.
Type the password (of up to 64 ASCII printable characters) associated with the user name
above.
Click Apply to save your changes back to the P-79X.
