8 help
9 Wide Area Networks (WANs), such as X.25, Frame Relay and leased
10 lines, are used to interconnect Local Area Networks (LANs) over vast
11 distances with data transfer rates significantly higher than those
12 achievable with commonly used asynchronous modem connections.
13
14 Usually, a quite expensive external device called a `WAN router' is
15 needed to connect to a WAN. As an alternative, a relatively
16 inexpensive WAN interface card can allow your Linux box to directly
17 connect to a WAN.
18
19 If you have one of those cards and wish to use it under Linux,
20 say Y here and also to the WAN driver for your card.
21
22 If unsure, say N.
