| Sam Ravnborg | 6a2e9b7 | 2005-07-11 21:13:56 -0700 | [diff] [blame] | 9 | Link Access Procedure, Balanced (LAPB) is the data link layer (i.e. |
| 10 | the lower) part of the X.25 protocol. It offers a reliable |
| 11 | connection service to exchange data frames with one other host, and |
| 12 | it is used to transport higher level protocols (mostly X.25 Packet |
| 13 | Layer, the higher part of X.25, but others are possible as well). |
| 14 | Usually, LAPB is used with specialized X.21 network cards, but Linux |
| 15 | currently supports LAPB only over Ethernet connections. If you want |
| 16 | to use LAPB connections over Ethernet, say Y here and to "LAPB over |
| 17 | Ethernet driver" below. Read |
