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.

350 Frame Relay is a fast low-cost way to connect to a remote Internet
351 access provider or to form a private wide area network. The one
352 physical line from your box to the local "switch" (i.e. the entry
353 point to the Frame Relay network, usually at the phone company) can
354 carry several logical point-to-point connections to other computers
355 connected to the Frame Relay network. For a general explanation of
356 the protocol, check out <http://www.mplsforum.org/>.
357
358 To use frame relay, you need supporting hardware (called FRAD) and
359 certain programs from the net-tools package as explained in
360 <file:Documentation/networking/framerelay.txt>.
361
362 To compile this driver as a module, choose M here: the
363 module will be called dlci.

370 How many logical point-to-point frame relay connections (the

381 Devices.

383 These are multi-protocol cards, but only Frame Relay is supported
384 by the driver at this time. Please read

398 You will need the wan-tools package which is available from

401 Note that the answer to this question won't directly affect the
402 kernel except for how subordinate drivers may be built:
403 saying N will just cause the configurator to skip all
404 the questions about WAN router drivers.

412 Cyclom 2X from Cyclades Corporation <http://www.avocent.com/> is an
413 intelligent multiprotocol WAN adapter with data transfer rates up to
414 512 Kbps. These cards support the X.25 and SNA related protocols.
415
416 While no documentation is available at this time please grab the
417 wanconfig tarball in
418 <http://www.conectiva.com.br/~acme/cycsyn-devel/> (with minor changes
419 to make it compile with the current wanrouter include files; efforts
420 are being made to use the original package available at
421 <ftp://ftp.sangoma.com/>).
422
423 Feel free to contact me or the cycsyn-devel mailing list at
424 <acme@conectiva.com.br> and <cycsyn-devel@bazar.conectiva.com.br> for
425 additional details, I hope to have documentation available as soon as
426 possible. (Cyclades Brazil is writing the Documentation).
427
428 The next questions will ask you about the protocols you want the
429 driver to support (for now only X.25 is supported).
