Abstract

An information transfer system is described for use in a telephone system wherein full duplex digital signal bursts containing a plurality of different types of information are transmitted between a central office and selected locations outside the system which may or may not be subscriber locations. Signal processing circuits receive and disassemble the digital signal bursts into digital information words each comprised of one of the types of information. Gateways are provided for each type of information for converting digital information words into a signal format for transmission to the selected locations. A digital switch couples the signal processing circuits to the gateways for routing the digital information words from the signal processing circuits to the gateways. A control system is coupled to the signal processing circuits, the gateways, and the digital switch for synchronously operating same and for placing each of the digital information words in a preallocated time slot corresponding to the source and destination of the information contained in the digital information word. The recited elements also operate in the reverse direction.
