^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 	  frame relay; the one physical line from your box to the X.25 network
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 	  entry point can carry several logical point-to-point connections
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 	  (called "virtual circuits") to other computers connected to the X.25
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 	  network. Governments, banks, and other organizations tend to use it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 	  to connect to each other or to form Wide Area Networks (WANs). Many
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 	  countries have public X.25 networks. X.25 consists of two
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 	  protocols: the higher level Packet Layer Protocol (PLP) (say Y here
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 	  if you want that) and the lower level data link layer protocol LAPB
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 	  (say Y to "LAPB Data Link Driver" below if you want that).
