An interphone system is an communication system linking rooms in a building, ship or aircraft. It is similar to an intercom system.
Uses
Interphone systems are used mainly in hotels, apartment buildings, ships and aircraft. They enable communication in several ways. Many interphone systems are push-to-talk (PTT) systems, much like walkie-talkies. Others, like many in apartment buildings, involve telephones.
Features
Most interphone systems also enable communication with outside locations. In many apartment buildings visitors push a button to communicate with a resident. The resident's phone rings and a conversation takes place. These devices also allow residents to place calls to outside locations. The same interphone system that enables a pilot to communicate with flight attendants on a commercial aircraft may also be used to communicate with radio towers.
Details
PTT systems are two-way audio connections using a central amplifier. In many systems, information is transferred through wires interconnecting the units. With current technology, some systems are now wireless. The wireless systems operate like standard walkie-talkies.
