Q. Illustrate the Simplex Transmission?
Simplex Transmission
Data in a simplex channel is always one way. Simplex channels aren't often used as it is not possible to send back error or control signals to the transmit end. An illustration of a simplex channel in a computer system is the interface between keyboard and computer, in that key codes need only be sent one way from the keyboard to computer system.
In this case, 24 simultaneous calls can be put through switch. Generally a 24-outlet Uni-selector is used as a selector hunter. Every one of the 24 outlets is connected to one two-
