Abstract: A four-wire "hoot-and-holler" telephone system provides full duplex conference communication. Four-wire desksets are provided for individual users, being connected by a four-wire telephone circuit. Repeaters at each end of the four-wire circuit provide incoming and outgoing amplification or attenuation for the desksets. Each such deskset includes a console with a speaker and a volume control for the speaker. Four-wire desksets are included in the system for connection to the telephone circuit in lieu of the repeater and the desksets. Each testset includes a self-test circuit and a switch feature for switching between normal and self-test operations. The testset includes also circuitry for allowing it to be used as a substitute for the desksets and the repeater as a stand-alone telephone set. Talk battery is provided by a local power supply of the test set.
