ABSTRACT:
An integrated building control system which includes a digital, time-multiplexed, multi-channel voice/data bus for conducting voice and data, a local operating network bus for conducting communication and control processor protocol signals, a CO-RES bus having sets of tip and ring lines for conducting analog voice and data signals, a line card unit having a line card communication and control processor, the line card unit coupled to the CO-RES bus, to a set of central office lines and to a corresponding set of resident telephone lines, and operative to activate switches so as to couple selected ones of the CO and resident telephone lines to the CO-RES bus, a line interface unit having a line interface communication and control processor, the line interface unit coupled to the CO-RES Bus and to the voice/data bus, and operative to provide digital signal processing capabilities, a digital interface unit having a digital interface communication and control processor, the digital interface unit coupled to the voice/data bus and operative to receive, route and transmit digital voice and data signals to and from the voice/data bus. An entrance panel unit having an entrance panel communication and control processor, has means for receiving information, means for displaying output information, and means for controlling building access. Each of the communication and control processors are coupled to a common local operating network bus and engage in distributed, peer-to-peer communications and control and monitor the operation of components of their respective units.
