Abstract:
A plug-and-play interface circuit comprising:a basic plug-and-play circuit comprising a communications controller for effecting communications between an upstream communication device and at least one downstream communication device, said basic plug-and-play circuit including a microprocessor for controlling said plug-and-play interface circuit; at least one downstream communication port coupled to said communications controller for coupling a downstream communication device to said communications controller, said communications controller receiving dynamic communication port information from the downstream communication device through said downstream communication port, said dynamic communication port information including status and configuration information of the downstream communication device; an upstream communication port coupled to said communications controller for coupling a remote upstream communication device to said communications controller, said communications controller transmitting said dynamic communication port information through said upstream communication port to the remote upstream communication device and said communications controller; input means for receiving data from a user, said input means being electrically connected to the microprocessor of said basic plug-and-play circuit, said data from the user including instructions to modify said dynamic communication port information transmitted to the remote upstream communication device; display means for displaying static display information combined with said dynamic communication port information to said user, said display means being electrically connected to and controlled by the microprocessor of said basic plug-and-play circuit; and memory means for storage of said static display information, said memory means being connected to and controlled by said microprocessor of said basic plug-and-play circuit for selectively conveying the static display information to the display means.
