The following terms and concepts may help as you read this chapter.
WAN IP Addre ss
The WAN IP address is an IP address for the XMG, which makes it accessible from an outside network. It is
used by the XMG to communicate with other devices in other networks. It can be static (fixed) or
dynamically assigned by the ISP each time the XMG 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).
AT M
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
PT M
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.
IPv6 Intro duc tio n
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in
IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10
can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and supports IPv6 rapid deployment
(6RD).
