WAN IP Address
The WAN IP address is an IP address for the P-79X, which makes it accessible from an outside
network. It is used by the P-79X to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the P-79X tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es).
ATM
Asynchronous Transfer Mode (ATM) is a WAN networking technology that provides high-speed data
transfer. ATM uses fixed-size packets of information called cells. With ATM, a high QoS (Quality of
Service) can be guaranteed. ATM uses a connection-oriented model and establishes a virtual circuit
(VC) between Finding Out More
PTM
Packet Transfer Mode (PTM) is packet-oriented and supported by the VDSL2 standard. In PTM,
packets are encapsulated directly in the High-level Data Link Control (HDLC) frames. It is designed
to provide a low-overhead, transparent way of transporting packets over DSL links, as an
alternative to ATM.
3G
3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is
optimized as multiple users share the same channel and bandwidth is only allocated to users when
they send data. It allows fast transfer of voice and non-voice data and provides broadband Internet
access to mobile devices.

7.1.3 Before You Begin

You need to know your Internet access settings such as encapsulation and WAN IP address. Get this
information from your ISP.

7.2 The 3G WAN Setup Screen

The USB port (at the rear panel of the P-79X) allow you to attach a 3G dongle to wirelessly connect
to a 3G network for Internet access. You can have the P-79X use the 3G WAN connection as a
backup. Disconnect the DSL and Ethernet WAN ports to use the 3G dongle as your primary WAN
connection. The P-79X automatically uses a wired WAN connection when available.
