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:
“Our frigate takes fire,
The other asks if we demand quarter?
If our colors are struck and the fighting done?
Now I laugh content for I hear the voice of my little captain,
We have not struck, he composedly cries, we have just begun our part of the fighting.”
—Walt Whitman (1819–1892)
