wan devices configuration

Wan interfaces[]

- depends on NETDEVICES

Option: WAN
- Kernel Versions: 2.6.15.6 ...
- (on/off) Wan interfaces support
  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.

There is no way to detect a comtrol sv11 - force it modular for now.

Option: HOSTESS_SV11
- Kernel Versions: 2.6.15.6 ...
- (on/off/module) Comtrol Hostess SV-11 support
- depends on WAN && ISA && m && ISA_DMA_API
  Driver for Comtrol Hostess SV-11 network card which operates on low speed synchronous serial links at up to 256kbit/s, supporting PPP and Cisco HDLC.
  
  The driver will be compiled as a module: the module will be called hostess_sv11.

The COSA/SRP driver has not been tested as non-modular yet.

Option: COSA
- Kernel Versions: 2.6.15.6 ...
- (on/off/module) COSA/SRP sync serial boards support
- depends on WAN && ISA && m && ISA_DMA_API
  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.

Option: DSCC4

- (on/off/module) Etinc PCISYNC serial board support
- depends on WAN && PCI && m
  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.

Option: DSCC4_PCISYNC
- Kernel Versions: 2.6.15.6 ...
- (on/off) Etinc PCISYNC features
- depends on 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.

Option: DSCC4_PCI_RST
- Kernel Versions: 2.6.15.6 ...
- (on/off) Hard reset support
- depends on DSCC4
  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.

Lan Media's board. Currently 1000, 1200, 5200, 5245

  - 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 syncPPP vs Cisco HDLC or 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.

  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/>.
