Synchronous Data Link Control. A protocol for managing synchronous, code-transparent, serial-by-bit information transfer over a link connection. Transmission exchanges may be full-duplex or half-duplex over switched or nonswitched links. The configuration of the link connection may be point-to-point, multipoint, or loop.
Synchronous Data Link Control. The SNA data link protocol equivalent to the IEEE 802.2 Logical Link Control (LLC) sublayer protocol.
acronym for Synchronous Data Link Control which is a bit-oriented, error-correcting communications protocol invented by IBM for use in conjunction with SNA as a successor to bisync
An IBM protocol for use in SNA (System Network Architecture) environments. It controls an individual link while catering for other network needs and can operate over full or half duplex lines. SDLC is a bit oriented protocol, using a variety of patterns to flag the beginning and end of a frame or packet. Different bit patterns are used to convey address, control and header fields which accompany the transmission and guide the frame to its destination.
Synchronous Data Link Control. A protocol based on HDLC (High-level Data Link Control). An IBM term for a link protocol used to transfer data between nodes.

Synchronous data link control. Protocol supported by the AS/400 for communicating with other AS/400, IBM mainframe, System/36, and System/38 systems.
Synchronous Data Link Control. (7/96)
Synchronous Data Link Control. Full duplex (receive and send at the same time), synchronous protocol transparent to the receiving hardware. Calculates the positions of fields within the frame from the start and end flags.

Synchronous Data Link Control.A data transfer protocol used in IBM's SNA networks.SDLC conforms to ISO's High-level Data Link Control (HDLC) and ANSI's Advanced Data Communication Control Procedures (ADCCP).
Synchronous data link control. (1) A form of communications line control that uses commands to control the transfer of data over a communications line. (2) A communications discipline conforming to subsets of the Advanced Data Communication Control Procedures (ADCCP) of the American National Standards Institute (ANSI) and High-Level Data Link Control (HDLC) of the International Organization for Standardization (ISO), for transferring synchronous, code-transparent, serial-by-bit information over a communications line. Transmission exchanges may be duplex or half-duplex over switched or nonswitched lines. The configuration of the connection may be point-to-point, multipoint, or loop.
A protocol developed by IBM for software applications and communicating devices operating in IBMs.
Synchronous Data Link Control. SDLC was invented by IBM to replace the older bisynchronous protocol for wide area connections between IBM equipment. A variation of the ISO HDLC protocol called HDLC Normal Response Mode (NRM) is essentially the same as SDLC.
Synchronous Data Link Control. Software protocol for Layer 2 of the seven-layer OSI communications model. This is based on an HDLC Frame with an eight bit address. As the name implies, it is a synchronous protocol and involves transmission of a clock signal along with the data.
Synchronous Data Link Control; a protocol similar to HDLC that is part of IBM's SNA communications protocol suite. SDLC is used for point-to-point and multipoint communications.
Sends Synchronous Data Link Control (SDLC) notifications.
An IBM protocol for use in SNA environment. SDLC is a bit oriented protocol, similar to HDLC.
IBM standard protocol superseding BSE.
Synchronous Data Link Control. Primary protocol used in BM SNA networks.
The Data-link layer of SNA, SDLC is a more efficient method than the older bisync protocol when it comes to packaging data for transmission between computers. Packets of data are sent over the line wi ... more
Synchronous data link control. A network protocol.
An IBM data-link layer protocol associated with SNA. In contrast to BSC, SDLC provides for full-duplex transmission and is more efficient.
