^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) Link Access Procedure, Balanced (LAPB) is the data link layer (i.e.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) the lower) part of the X.25 protocol. It offers a reliable
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) connection service to exchange data frames with one other host, and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) it is used to transport higher level protocols (mostly X.25 Packet
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) Layer, the higher part of X.25, but others are possible as well).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) Usually, LAPB is used with specialized X.21 network cards, but Linux
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) currently supports LAPB only over Ethernet connections. If you want
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) to use LAPB connections over Ethernet, say Y here and to "LAPB over
