ABSTRACT:
A method and apparatus for automatically and dynamically providing wiring connections at a central location coupled via ordinary phone lines to a plurality of work stations including a master work station. A central hub couples to a plurality of two wire telephone lines, each of which is coupled to an individual work station. The hub includes circuitry for monitoring transmissions to determine which of the work stations is the master. A receiver coupled to the master work station is coupled to transmitters to each of the other work stations. Receivers coupled to the remaining work stations are in turn coupled to a transmitter to the master work station.
