A telephone exchange is an infrastructure that connects subscribers to the Public Switched Telephone Network (PSTN, Public subscriber telephone network) or to private networks.
A telephone exchange contains network interfaces that allow the simultaneous exchange of multiple voice channels and support switching facilities, thus allowing the subscribers on a specific location to communicate with each other via telephone links.
It is used to connect a large number of subscriber telephones to their required exchanges, long-distance calls, etc.
Large numbers called each other from different exchanges and hence it is very necessary to contain a large number of lines into a small area (telephone exchange).

A telephone exchange is the basic unit of modern telephone switching systems. A telephone exchange consists of a system of cabling, switching equipment, that controls the routing of telephone calls to individual line circuits or subscriber Trunk Dialling (TDD) lines.
