1. A system for multiplexing information from a plurality of ports each having a physical position identification code onto a TDM bus for transmitting said information in time slots on said bus, said system comprising:

  • a processor controlled means for selectively generating and outputting physical position identification codes during time slots of said TDM bus;

    a distributing means connected to said processor controlled means for distributing said physical position identification codes through said system; and

    connecting means associated with each of said ports for connecting information from said ports to said TDM bus, each said connecting means assuming the physical position identification code of the associated port and being connected to said distributing means, said connecting means being responsive to the presence of its assumed physical position identification code on said distributing means to connect the information from its associated port to the TDM bus, whereby each connecting means connects information from its associated port to said TDM bus in a time slot when said physical position identification code on said distributing means matches its physical position identification code assumed by the connecting means.
