See Link Access Procedure, Balanced.
(link access procedure balanced) X.25 represents Levels 2 and 3 of the OSI reference model; LAPB is the protocol that implements Level 2. This protocol provides a mechanism to exchange data (frames), detect out-of-sequence or missing frames, and provide for retransmission and acknowledgment.
Link Access Protocol - B Channel. Standard protocol for ISDN that defines the data in the 2 voice ("B") channels of the 192 kbps ISDN signal.
Link Access Protocol Balanced. (Protocolo de Acceso de Enlace Balanceado.)
Link Access Procedure, Balanced. Data link layer protocol in the X.25 protocol stack. LAPB is a bit-oriented protocol derived from high-level data link control (HDLC).
Link Access Procedure Balanced or Link Access Protocol Balanced. A protocol used for accessing an X.25 network at the link level. X.25 also specifies a LAP, or link access procedure (not balanced). Both LAP and LAPB are full-duplex, point-to-point bit-synchronous protocols. See also LAP.
Link Access Procedure, Balanced. Data link layer protocol in the X.25 protocol stack. LAPB is a bit-oriented protocol derived from HDLC. See also HDLC and X.25.
A modified form of HDLC that the ITU-T chose as the link-level protocol for X.25 networks. LAPB provides for the reliable transfer of a packet from a host to an X.25 packet switch, which then forwards the packet on to its destination.
Link-access procedure balanced. See also link-access procedures.
LAPB (Link Access Protocol, Balanced) is a data link layer protocol in the X.25 protocol stack. LAPB is a bit-oriented protocol derived from HDLC that ensures that frames are error free and in the right sequence.
