  • Patent number: 5905790
    Abstract: An interconnect circuit is described which provides automatic three-way connection between a single base telephone line and any telephone destination, while under control of a caller from a remote location. The device may be used to make long distance calls or local calls, automatically connecting the lines to the remote caller, while telephone charges are billed to the single base telephone account. The invention device incorporates a programmable microprocessor that operates the circuit according to a program and will also accept instructions from the remote caller to program the calls in any given sequence or combination. Circuit components are operated low in stress, at low power and are few in number. Thus the circuit has high reliability and the device is low cost.
