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:
“Most of the ladies and gentlemen who mourn the passing of the nation’s leaders wouldn’t know a leader if they saw one. If they had the bad luck to come across a leader, they would find out that he might demand something from them, and this impertinence would put an abrupt and indignant end to their wish for his return.”
—Lewis H. Lapham (b. 1935)
