摘要： A combined telecommunications and data communications system operates by partitioning data wherein the PCM speech transmission data field is used to contain both digitized speech and other data in the same channel within a frame. Thus the system enables speech and data to be combined in a common information field and to be simultaneously transmitted in the same channel, frame by frame, through a digital switching network. The system has a data base which is a computer coupled to a predetermined port of the switching network so that data transmitted from any subscriber can be received by the data base. The output of the data base is coupled to the tone bus so that the received data or the processed data from the data base can be coupled to any or all subscribers associated with the switching systems via the tone bus. This simultaneous broadcasting of data via the tone bus eliminates the need for additional channels in the switching network for transmitting data from the data base to subscribers. This advantage is realized by the use of the systems unique ability to combine and split digitized speech and data for transmission in the same channel, whereby data received at a port via the tone bus may be partitioned from the information field of the channel for use by a subscriber.

摘要： A combined telecommunications and data communications system operates by partitioning data wherein the PCM speech transmission data field is used to contain both digitized speech and other data in the same channel within a frame. Thus the system enables speech and data to be combined in a common information field and to be simultaneously transmitted in the same channel, frame by frame, through a digital switching network. The switching network contains a common port which has a digital interface connected to the port which digital interface can separate and combine the speech and the data fields. The digital interface is connected to a conference module which conference module receives the speech fields via a speech bus. The digital interface is further connected to a data base system which data base system receives the separated data fields via a data tone bus. Through the unique use of a digital interface for combining and separating speech and data fields from the information field of a channel, a conference module and a data base may both be connected to a single port thereby reducing the number of ports and network channels required for simultaneous conferencing and data base access.

摘要： The present invention discloses a data partitioning technique wherein the PCM speech transmission data field is utilized to contain both digitized speech (for example, from a telephone) and other data (for example, from a data terminal) in the same channel within a frame having a plurality of channels e.g. 32 channels, of information. This enables the speech and data to be combined in a common information field and simultaneously transmitted in the same channel, frame by frame, through a digital switching network to other system users. Also, in accordance with the present invention, system users can individually selectively access a data base system through the switching network, such that the same information can be broadcast from the database system to a plurality of system users, or such that different information can be accessed in the database system by a plurality of system users and simultaneously transmitted to different users in different channels. A novel technique for transmitting information from the database system via a telecommunication systems tone bus interconnecting the system is described.

摘要： In order to expand or increase the number of lines of a communications system, this disclosure enables connection of one PBX switching system to another by connecting the switching networks to junctors which establish a multichannel transmission link between the first PBX module and a second module of similar format. The junctor is treated internally in each PBX module as a line or trunk port and whenever an extension number which is not contained in the numbering plan of the individual module is dialed, the control unit of the PBX will direct that call to any free junctor. The complete dialed number is transmitted from the originating module via the junctor to a receiving junctor at the other switching system. The dialed number is received at the receiving junctor through the established communications path between junctors for channel associated signalling or through a common signalling channel through which signalling for all other junctors in the link is transmitted, and after synchronization, it is utilized to made a connection between the called terminal and the calling terminal via the control unit located at the second switching system. The unique use of junctors to connect PBX systems allows for the initial installation of a small system at low cost which system can be expanded in the field in a cost effective manner by merely adding on additional systems. The distance between systems and subscribers in a system has little or no effect on its performance.

摘要： A combined telecommunications and data communications system includes a digital switching network for allowing connections between one or more of a plurality of ports. The system described includes a tone module at one port which module includes a tone bus which can be connected to a plurality of other ports each associated with a terminal module. In the system a poll originating module is coupled to a given port of the switching network. The poll originating module can initiate a broadcast mode by transmitting a polling signal. Upon implementing the broadcast mode the switching network connects the polling originator module to the tone module. The tone module then transmits the polling signal during the broadcast mode to a plurality of ports. The polling request is decoded at each of the ports by means of a terminal interface module. In this manner each port will recognize a polling request and contain separate circuitry to respond to such a request through the switching network.

摘要： A system for transporting data between equipment connected to a subscriber telephone line and a provider of services connects with subscriber telephone lines at a central office of a telephone company. The system includes a set of first multiplexers which are coupled to individual ones of the subscriber lines at a point between the cross-switching of the central office and the subscriber premises. Output signals of the first multiplexers fan into a second multiplexer. Bidirectional communication is provided between each of the multiplexers and the subscriber equipment, and also between the second multiplexer and the service provider via a line scanner which generates command signals for the operation of the first and second multiplexers. The first multiplexers, the second multiplexer, the line scanner and a host computer of the service provider can be located at a distance from each other and may be coupled together by communication links which permit the bidirectional flow of data.

摘要： A circuit for adapting a telephone subscriber line to operate as a multiparty line is described wherein a plurality of conventional single line subscriber subsets are provided telephone service on the subscriber line such that each subscriber has privacy at all stages of call progress. In accordance with another feature of the present invention, frequency selective ringing is not required to prevent ringing from occuring at other subscriber subsets on the multiparty line when a party is called. The circuit of the present invention controls the switching of battery polarity at the central office to connect and disconnect subscribers from the line. The invention further provides automatic telephone number identification when calls are initiated by varying a unique identity tone for billing purposes. The invention also uniquely provides for user transparent reverting calling such that no special dialing procedure is required to make reverting calls and complete privacy is maintained, even on reverting calls.
