Abstract: A switched communications system including store and forward facilities is provided in accordance with the teachings of the present invention wherein, in an exemplary embodiment, any of a plurality of teleprinter or teletypewriter peripherals may be given access to the communication system and input information thereto destined for one or more peripherals thereof. Input information from a transmitting peripheral is stored under the control of a central switching system which acts to inspect the destination information associated therewith. If a destination peripheral employing facsimile equipment has been designated, a facsimile controller is enabled and destination information associated with the facsimile peripheral defined is provided thereto from the central switching system. In response to the destination information, telephone communication to the defined facsimile peripheral is initiated by said facsimile controller and an indication is provided thereby to the central switching system when a communications link with the defined facsimile peripheral has been established and the defined facsimile peripheral is ready to receive facsimile information. Phasing information is then exchanged between said facsimile controller and the defined facsimile peripheral and thereafter stored information destined for the facsimile peripheral defined is transformed into a digital signal capable of being decoded into a baseband signal and applied to said facsimile controller. The digital signals applied to the facsimile controller are decoded into a baseband signal which is then transformed into a suitable facsimile format and transmitted to the defined facsimile peripheral. Upon transmission of all of the stored information for the defined facsimile peripheral, the communications link established between the facsimile controller and the defined facsimile peripheral is terminated.
