Switches allow different nodes (a network connection point, typically a computer) of a network to communicate directly with one another in a smooth and efficient manner. Â­There are many different types of switches and networks.
Some telephone exchange buildings in small towns now house only remote or satellite switches, and are homed upon a parent switch, usually several kilometres away. The remote switch is dependent on the parent switch for routing and number plan information.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).
