6.1.2 What You Need to Know

The following terms and concepts may help as you read this chapter.
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set
up a WAN connection to the Internet, you need to use the same encapsulation method used by your
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
over Ethernet), they should also provide a username and password (and service name) for user
authentication.

WAN IP Address

The WAN IP address is an IP address for the Device, which makes it accessible from an outside
network. It is used by the Device to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the Device 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
