  8. X.25 is a set of standardized network protocols, similar in scope to
  9. frame relay; the one physical line from your box to the X.25 network
  10. entry point can carry several logical point-to-point connections
  11. (called "virtual circuits") to other computers connected to the X.25
  12. network. Governments, banks, and other organizations tend to use it
  13. to connect to each other or to form Wide Area Networks (WANs). Many
  14. countries have public X.25 networks. X.25 consists of two
  15. protocols: the higher level Packet Layer Protocol (PLP) (say Y here
  16. if you want that) and the lower level data link layer protocol LAPB
  17. (say Y to "LAPB Data Link Driver" below if you want that).
  18. You can read more about X.25 at <http://www.sangoma.com/x25.htm> and
  19. <http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/cbook/cx25.htm>.
  20. Information about X.25 for Linux is contained in the files
  21. <file:Documentation/networking/x25.txt> and
  22. <file:Documentation/networking/x25-iface.txt>.
  23. One connects to an X.25 network either with a dedicated network card
  24. using the X.21 protocol (not yet supported by Linux) or one can do
  25. X.25 over a standard telephone line using an ordinary modem (say Y
  26. to "X.25 async driver" below) or over Ethernet using an ordinary
  27. Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
  28. Driver" and "LAPB over Ethernet driver" below).
  29. To compile this driver as a module, choose M here: the module
  30. will be called x25. If unsure, say N.
