Abstract

See full text

A method of simultaneously transmitting information to a plurality of standard facsimile (fax) receivers in which each receiver may have timing and response characteristics which vary from other receivers, including the steps of transmitting by a selective carrier path a unitary signal from a unitary transmitter location to a plurality of fax receivers time-spaced ring signals, the number of ring signals being at least equal to the number of ring signals to which each of the receivers is responsive, delaying further transmission a preselected length of time during which the individual receivers generate standard calls, station identification and other signals which are irrelevant to the transmitter, transmitting predetermined command signals which are simultaneously received by the facsimile receivers as required to place all receivers in condition to receive a fax message, delaying further transmission at a preselected length of time during which the individual receivers generate standard confirmation to receive signals which are also irrelevant to the transmitter, transmitting a fax message simultaneously to the plurality of receivers and transmitting an end of procedure message simultaneously to the plurality of receivers. In an alternate embodiment, the fax receivers may include addressable codes so that information may be simultaneously transmitted only to those fax receivers which are addressed.
