In telecommunication, a demand assignment is a method which several users share access to a communications channel on a real-time basis, i.e., a user needing to communicate with another user on the same network requests the required circuit, uses it, and when the call is finished, the circuit is released, making the circuit available to other users.
Demand assignment is similar to conventional telephone switching, in which common trunks are provided for many users, on a demand basis, through a limited-size trunk group.
Famous quotes containing the word demand:
“risk is full: every living thing in
siege: the demand is life, to keep life: the small
white blacklegged egret, how beautiful, quietly stalks and spears
the shallows, darts to shore
to stab—”
—Archie Randolph Ammons (b. 1926)
