Synchronous Data Link Control

There's also a move to higher-speed operation and the ability to function with bit-oriented protocols, such as High-level Data Link Control (HDLC), specified in the X.25 standard, or IBM's Synchronous Data Link Control (SDLC).
Synchronous Data Link Control is (at last) a real protocol.
