menuconfig WAN
	bool "Wan interfaces support"
	help
	  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.

	  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

	  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.rst>.

	  To compile this driver as a module, choose M here: the

	  Devices.

	  These are multi-protocol cards, but only Frame Relay is supported
	  by the driver at this time. Please read
	  <file:Documentation/networking/framerelay.rst>.

	  To compile this driver as a module, choose M here: the
	  module will be called sdla.

	help
	  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.

	depends on LAPB && X25 && TTY
	help
	  Send and receive X.25 frames over regular asynchronous serial

config SBNI_MULTILINE
	bool "Multiple line feature support"
	depends on SBNI
	help
	  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.
