Wide Area Networks (WANs), such as X.25, Frame Relay and leased lines, are used to interconnect Local Area Networks (LANs) over vast distances with data transfer rates significantly higher than those achievable with commonly used asynchronous modem connections. Usually, a quite expensive external device called a `WAN router' is needed to connect to a WAN. As an alternative, a relatively inexpensive WAN interface card can allow your Linux box to directly connect to a WAN. If you have one of those cards and wish to use it under Linux, say Y here and also to the WAN driver for your card. If unsure, say N.
Driver for Comtrol Hostess SV-11 network card which operates on low speed synchronous serial links at up to 256Kbps, supporting PPP and Cisco HDLC. The driver will be compiled as a module: the module will be called hostess_sv11.
Driver for COSA and SRP synchronous serial boards. These boards allow to connect synchronous serial devices (for example base-band modems, or any other device with the X.21, V.24, V.35 or V.36 interface) to your Linux box. The cards can work as the character device, synchronous PPP network device, or the Cisco HDLC network device. You will need user-space utilities COSA or SRP boards for downloading the firmware to the cards and to set them up. Look at the <http://www.fi.muni.cz/~kas/cosa/> for more information. You can also read the comment at the top of the <file:drivers/net/wan/cosa.c> for details about the cards and the driver itself. The driver will be compiled as a module: the module will be called cosa.
Driver for the following Lan Media family of serial boards: - LMC 1000 board allows you to connect synchronous serial devices (for example base-band modems, or any other device with the X.21, V.24, V.35 or V.36 interface) to your Linux box. - LMC 1200 with on board DSU board allows you to connect your Linux box directly to a T1 or E1 circuit. - LMC 5200 board provides a HSSI interface capable of running up to 52 Mbits per second. - LMC 5245 board connects directly to a T3 circuit saving the additional external hardware. To change setting such as clock source you will need lmcctl. It is available at <ftp://ftp.lanmedia.com/> (broken link). To compile this driver as a module, choose M here: the module will be called lmc.

This driver is broken because of struct tty_driver change. Driver for the Cyclades-PC300 synchronous communication boards. These boards provide synchronous serial interfaces to your Linux box (interfaces currently available are RS-232/V.35, X.21 and T1/E1). If you wish to support Multilink PPP, please select the option later and read the file README.mlppp provided by PC300 package. To compile this as a module, choose M here: the module will be called pc300. If unsure, say N.
Multilink PPP over the PC300 synchronous communication boards.
Alternative driver for PC300 RSV/X21 PCI cards made by Cyclades, Inc. If you have such a card, say Y here and see <http://www.kernel.org/pub/linux/utils/net/hdlc/>. To compile this as a module, choose M here: the module will be called pc300too. If unsure, say N here.

Support for the FarSync T-Series X.21 (and V.35/V.24) cards by FarSite Communications Ltd. Synchronous communication is supported on all ports at speeds up to 8Mb/s (128K on V.24) using synchronous PPP, Cisco HDLC, raw HDLC, Frame Relay or X.25/LAPB. If you want the module to be automatically loaded when the interface is referenced then you should add "alias hdlcX farsync" to /etc/modprobe.conf for each interface, where X is 0, 1, 2, ..., or simply use "alias hdlc* farsync" to indicate all of them. To compile this driver as a module, choose M here: the module will be called farsync.
Driver for Etinc PCISYNC boards based on the Infineon (ex. Siemens) DSCC4 chipset. This is supposed to work with the four port card. Take a look at <http://www.cogenit.fr/dscc4/> for further information about the driver. To compile this driver as a module, choose M here: the module will be called dscc4.
Due to Etinc's design choice for its PCISYNC cards, some operations are only allowed on specific ports of the DSCC4. This option is the only way for the driver to know that it shouldn't return a success code for these operations. Please say Y if your card is an Etinc's PCISYNC.
Various DSCC4 bugs forbid any reliable software reset of the ASIC. As a replacement, some vendors provide a way to assert the PCI #RST pin of DSCC4 through the GPIO port of the card. If you choose Y, the driver will make use of this feature before module removal (i.e. rmmod). The feature is known to be available on Commtech's cards. Contact your manufacturer for details. Say Y if your card supports this feature.
Say Y here if you want to use built-in HSS ports on IXP4xx processor.
Support for the Frame Relay protocol. Frame Relay is a fast low-cost way to connect to a remote Internet access provider or to form a private wide area network. The one physical line from your box to the local "switch" (i.e. the entry point to the Frame Relay network, usually at the phone company) can carry several logical point-to-point connections to other computers connected to the Frame Relay network. For a general explanation of the protocol, check out <http://www.mplsforum.org/>. To use frame relay, you need supporting hardware (called FRAD) and certain programs from the net-tools package as explained in <file:Documentation/networking/framerelay.txt>. To compile this driver as a module, choose M here: the module will be called dlci.
How many logical point-to-point frame relay connections (the identifiers of which are called DCLIs) should be handled by each of your hardware frame relay access devices. Go with the default.
Driver for the Sangoma S502A, S502E, and S508 Frame Relay Access Devices. These are multi-protocol cards, but only Frame Relay is supported by the driver at this time. Please read <file:Documentation/networking/framerelay.txt>. To compile this driver as a module, choose M here: the module will be called sdla.
Connect LAN to WAN via Linux box. Select driver your card and remember to say Y to "Wan Router." You will need the wan-tools package which is available from <ftp://ftp.sangoma.com/>. Note that the answer to this question won't directly affect the kernel except for how subordinate drivers may be built: saying N will just cause the configurator to skip all the questions about WAN router drivers. If unsure, say N.
Cyclom 2X from Cyclades Corporation <http://www.avocent.com/> is an intelligent multiprotocol WAN adapter with data transfer rates up to 512 Kbps. These cards support the X.25 and SNA related protocols. While no documentation is available at this time please grab the wanconfig tarball in <http://www.conectiva.com.br/~acme/cycsyn-devel/> (with minor changes to make it compile with the current wanrouter include files; efforts are being made to use the original package available at <ftp://ftp.sangoma.com/>). Feel free to contact me or the cycsyn-devel mailing list at <acme@conectiva.com.br> and <cycsyn-devel@bazar.conectiva.com.br> for additional details, I hope to have documentation available as soon as possible. (Cyclades Brazil is writing the Documentation). The next questions will ask you about the protocols you want the driver to support (for now only X.25 is supported). If you have one or more of these cards, say Y to this option. To compile this driver as a module, choose M here: the module will be called cyclomx.
Connect a Cyclom 2X card to an X.25 network. Enabling X.25 support will enlarge your kernel by about 11 kB.
Driver for a pseudo device (typically called /dev/lapb0) which allows you to open an LAPB point-to-point connection to some other computer on your Ethernet network. In order to do this, you need to say Y or M to the driver for your Ethernet card as well as to "LAPB Data Link Driver". To compile this driver as a module, choose M here: the module will be called lapbether. If unsure, say N.
Send and receive X.25 frames over regular asynchronous serial lines such as telephone lines equipped with ordinary modems. Experts should note that this driver doesn't currently comply with the asynchronous HDLS framing protocols in CCITT recommendation X.25. To compile this driver as a module, choose M here: the module will be called x25_asy. If unsure, say N.
Driver for ISA SBNI12-xx cards which are low cost alternatives to leased line modems. You can find more information and last versions of drivers and utilities at <http://www.granch.ru/>. If you have any question you can send email to <sbni@granch.ru>. To compile this driver as a module, choose M here: the module will be called sbni. If unsure, say N.
Schedule traffic for some parallel lines, via SBNI12 adapters. If you have two computers connected with two parallel lines it's possible to increase transfer rate nearly twice. You should have a program named 'sbniconfig' to configure adapters. If unsure, say N.
