Virtual circuit
virtual circuit (VC)
A
communications arrangement in which
data from a
source user may be passed to a
destination user over various real
circuit configurations during a single period of communication. (

set up on a per-
call basis and are disconnected when the call is terminated; however, a
permanent virtual circuit can be established as an option to provide a dedicated
link between two facilities. Synonyms logical circuit, logical route.
