  • Patent number: 4578789
    Abstract: 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.

  • Patent number: 4185245
    Abstract: A fault-tolerant clock signal distribution system for a plurality of equipment units is disclosed. Fault tolerance is achieved by independent bussing of clock signals from each of a pair of duplicated clock sources to a plurality of clock receiver units, each receiver unit associated with one of the plurality of equipment units and including sequential logic apparatus operative to examine the two clock signal trains bussed to the clock receiver unit and to ignore that signal train that phase lags the other. In case the phase leading clock source or its transmission bus fails, the remaining clock signal takes over. Because the outputs of the duplicated clock sources are distributed over separate busses, either source may comprise the phase-leading clock at any particular clock receiver unit.
