5.2 What You Need to Know
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) or PPPoA, 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 ZyXEL Device, which makes it accessible from
an outside network. It is used by the ZyXEL Device to communicate with other devices in
other networks. It can be static (fixed) or dynamically assigned by the ISP each time the
ZyXEL 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) (and a gateway IP address if you use the Ethernet or ENET
ENCAP encapsulation method).
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.
5.3 Before You Begin
You need to know your Internet access settings such as encapsulation and WAN IP address.
Get this information from your ISP.
