CONFIG_LAPBETHER
  This is a 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".

  If you want to compile this driver as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called lapbether.o.  If unsure, say N.

CONFIG_X25_ASY
  This is a driver for sending and receiving 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.

  If you want to compile this driver as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called x25_asy.o.  If unsure, say N.

CONFIG_SEALEVEL_4021
  This is a driver for the Sealevel Systems ACB 56 serial I/O adapter.

  This driver can only be compiled as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  If you want to do that, say M here. The module will be called
  sealevel.o.

CONFIG_SYNCLINK_SYNCPPP
  Enables HDLC/SYNCPPP support for the SyncLink WAN driver.
  Normally the SyncLink WAN driver works with the main PPP
  driver (ppp.c) and pppd program. HDLC/SYNCPPP support allows use
  of the Cisco HDLC/PPP driver (syncppp.c).
  The SyncLink WAN driver (in character devices) must also be enabled.

CONFIG_FARSYNC
  This driver supports the FarSync T-Series X.21 (and V.35/V.24) cards
  from 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 to compile this driver as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want)
  say M here and read <file:Documentation/modules.txt>.
  The module will be called farsync.o and if you want the module to be
  automatically loaded when the interface is referenced then you
  should add "alias hdlcX farsync" to /etc/modules.conf for each
  interface, where X is 0, 1, 2, ...

CONFIG_DLCI
  This is 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.frforum.com/> on the WWW. 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>.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called dlci.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_DLCI_COUNT
  This is the maximal number of logical point-to-point frame relay
  connections (the identifiers of which are called DCLIs) that
  the driver can handle. The default is probably fine.

CONFIG_DLCI_MAX

  connections (the identifiers of which are called DCLIs) should be
  handled by each of your hardware frame relay access devices. Go with
  the default.

CONFIG_SDLA
  Say Y here if you need a 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/framerelay.txt>.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called sdla.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_WAN
  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, below.

  If unsure, say N.

CONFIG_HOSTESS_SV11
  This is a network card for low speed synchronous serial links, at
  up to 256Kbps. It supports both PPP and Cisco HDLC.

  At this point, the driver can only be compiled as a module.

CONFIG_COSA
  This is a 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.

  To actually use the COSA or SRP board, you will need user-space
  utilities 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 about the cards (including the pointer to the user-space
  utilities). 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 ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called cosa.o. For general information about
  modules read <file:Documentation/modules.txt>.

CONFIG_DSCC4
  This is a driver for Etinc PCISYNC boards based on the Infineon
  (ex. Siemens) DSCC4 chipset. It is supposed to work with the four
  ports card. Take a look at <http://www.cogenit.fr/dscc4/>
  for further informations about the driver and his configuration.

  The driver will be compiled as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called dscc4.o. For general information about
  modules read <file:Documentation/modules.txt>.

CONFIG_LANMEDIA
  This is a 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 dirrectly 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 syncPPP vs cisco HDLC or clock source you
  will need lmcctl.  It is available at <ftp://ftp.lanmedia.com/>.

  This code is also available as a module called lmc.o ( = code
  which can be inserted in and removed from the running kernel
  whenever you want). If you want to compile it as a module, say M
  here and read <file:Documentation/modules.txt>.

CONFIG_SBNI
  This is a driver for ISA SBNI12-xx cards which are low cost
  alternatives to leased line modems. Say Y if you want to insert
  the driver into the kernel or say M to compile it as a module (the
  module will be called sbni.o).

  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.

  Say N if unsure.

CONFIG_SBNI_MULTILINE
  Schedule traffic for some parallel lines, via SBNI12 adapters.
  If you have two computers connected with two parallel lines it's

  If you have a WAN interface card and you want your Linux box to act
  as a WAN router, thereby connecting you Local Area Network to the
  outside world over the WAN connection, say Y here and then to the
  driver for your card below. In addition, you need to say Y to "Wan
  Router".

  You will need the wan-tools package which is available from
  <ftp://ftp.sangoma.com/>. Read
  <file:Documentation/networking/wan-router.txt> for more information.

  Note that the answer to this question won't directly affect the
  kernel: saying N will just cause the configurator to skip all
  the questions about WAN router drivers. If unsure, say N.

CONFIG_VENDOR_SANGOMA
  WANPIPE from Sangoma Technologies Inc. (<http://www.sangoma.com/>)
  is a family of intelligent multiprotocol WAN adapters with data
  transfer rates up to 4Mbps. They are also known as Synchronous
  Data Link Adapters (SDLA) and are designated as S514-PCI or
  S508-ISA.  These cards support

    - X.25, Frame Relay, PPP, Cisco HDLC protocols.

    - API support for protocols like HDLC (LAPB),
      HDLC Streaming, X.25, Frame Relay and BiSync.
