9 | X.25 is a set of standardized network protocols, similar in scope to | |
10 | frame relay; the one physical line from your box to the X.25 network | |
11 | entry point can carry several logical point-to-point connections | |
12 | (called "virtual circuits") to other computers connected to the X.25 | |
13 | network. Governments, banks, and other organizations tend to use it | |
14 | to connect to each other or to form Wide Area Networks (WANs). Many | |
15 | countries have public X.25 networks. X.25 consists of two | |
16 | protocols: the higher level Packet Layer Protocol (PLP) (say Y here | |
17 | if you want that) and the lower level data link layer protocol LAPB | |
18 | (say Y to "LAPB Data Link Driver" below if you want that). | |

20 | You can read more about X.25 at <http://www.sangoma.com/x25.htm> and | |
21 | <http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/cbook/cx25.htm>. | |
22 | Information about X.25 for Linux is contained in the files | |
23 | <file:Documentation/networking/x25.txt> and | |
24 | <file:Documentation/networking/x25-iface.txt>. | |
25 | ||
26 | One connects to an X.25 network either with a dedicated network card | |
27 | using the X.21 protocol (not yet supported by Linux) or one can do | |
28 | X.25 over a standard telephone line using an ordinary modem (say Y | |
29 | to "X.25 async driver" below) or over Ethernet using an ordinary | |
30 | Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link | |
31 | Driver" and "LAPB over Ethernet driver" below). | |

33 | To compile this driver as a module, choose M here: the module | |
34 | will be called x25. If unsure, say N. | |
