SDLC
SDLC (Synchronous Data Link Control) is the primary data link protocol used
for wide-area network connections within SNA. It is used to manage
information exchanged across a single physical data link between two nodes.
SDLC is part of the original design of SNA, and is the foundation upon which
all other connections are based. The Eiconcard supports point-to-point,
multipoint, and switched dial-up SDLC links.
