HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. Various subsets of HDLC have been developed under the name of Link Access Procedure (LAP).In HDLC, one side is set up as the primary control station and the other as secondary. In Normal mode, the secondary station responds to requests only from the primary station. In Asynchronous mode, the secondary can initiate transmission, and in Asynchronous Balanced mode, both sides can send and receive over full-duplex lines. See LAP and SDLC. HDLC (communications)

No references found | The effect of moderate regular uptake of alcohol (10 g ethanol=300 ml beer or 1 1/2 glasses of wine daily) is to raise the HDLC levels by 0. The module supports all ATM machines using Bisync technology, as well as SDLC, HDLC, RS-232, RS-422, RS-485 SNA, and X. For communication, industrial, and office automation (OA) applications, the added HDLC communication function is particularly important because it can implement fast, highly reliable data transfers between system elements. |
