Abstract
An intercom system for remote banking which facilitates communication between a teller terminal and a remotely located customer terminal. A two-way speaker is provided at the customer location and a separate microphone and a speaker are provided at the teller location. An amplifier in the communication path linking the two stations is connected such that normally its input is responsive to the customer two-way speaker with its output feeding the teller speaker, permitting the customer to talk to the teller. When the teller speaks into the microphone, and assuming certain conditions are met, the amplifier automatically switches to connect the teller microphone to the amplifier input and the customer two-way speaker to the amplifier output, permitting the teller to talk to the customer. To avoid switching communication direction in response to noise at the teller location, the system is additionally provided with a noise microphone located at the teller station for transducing ambient noise thereat, and means responsive to the output of the noise and teller microphones for switching the system to the teller speech transmission mode only when a source of teller speech is located within a predetermined region enclosing the teller speech microphone, which region excludes therefrom the noise microphone. Switching of the system to the teller speech transmission mode occurs, assuming a teller speech source is located within the predetermined region surrounding the teller microphone, notwithstanding that a source of noise is present, providing the noise source is located exteriorly of said predetermined region.
