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:
“...America has enjoyed the doubtful blessing of a single-track mind. We are able to accommodate, at a time, only one national hero; and we demand that that hero shall be uniform and invincible. As a literate people we are preoccupied, neither with the race nor the individual, but with the type. Yesterday, we romanticized the “tough guy;” today, we are romanticizing the underprivileged, tough or tender; tomorrow, we shall begin to romanticize the pure primitive.”
—Ellen Glasgow (1873–1945)
