In a telecommunications network, a switch is a device that channels incoming data from any of multiple input ports to the specific output port that will take the data toward its intended destination.n a wide area packet-switched network such as the Internet, a switch determines from the IP address in each packet which output port to use for the next part of its trip to the intended destination.
Telephone switches are a small component of a large network. The majority of work and expense of the phone system is the wiring outside the central office, or the outside plant. In the middle 20th century, each subscriber telephone number required an individual pair of wires from the switch to the subscriber's phone.raditional telephone switches connected physical circuits (e.g., wire pairs) while modern telephone switches use a combination of space-and time-division switching. In other words, each voice channel is represented by a time slot (say 1 or 2) on a physical wire pair (A or B).
