Building communication and control system

An integrated building control system, comprising:

• (a) a digital, time-multiplexed, multi-channel voice/data bus for conducting voice and data;
• (b) a local operating network (LON) bus for conducting communication and control processor protocol signals;
• (c) a Central Office Resident (CO-RES) bus having sets of tip and ring lines for conducting analog voice and data signals;
• (d) a plurality of line card units each having a line card communication and control processor, said line card units coupled to said 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 said central office lanes and said resident telephone lines to said CO-RES bus;
• (e) a line interface unit having a line interface communication and control processor, said line interface unit coupled to said CO-RES Bus and to said digital voice/data bus, and operative to interface between lines of said CO-RES Bus and said digital voice/data bus;
• (f) a digital interface unit having a digital interface communication and control processor, said digital interface unit coupled to said digital voice/data bus and operative to receive, route and transmit digital voice and data signals to and from said digital voice/data bus;
• and
• (g) an entrance panel unit coupled to said digital interface unit and operative to receive from and transmit to said digital interface unit digital voice and data signals, said entrance panel unit having a relay coupled to unlock in entrance door in response to activation of said relay, a resident data base to store information concerning residents, a digital signal processor for digitizing and compressing analog voice and data signals, means for displaying output information, an entrance panel communication and control processor coupled to each of said relay, said displaying means and said digital signal processor and operative to control the operation of each;
• wherein said communication and control processors on said line card unit, said line interface unit, said digital interface unit and said entrance panel unit are coupled to said LON bus and monitor fie operation of components on respective ones of said line card unit, said line interface unit, said digital interface unit, and said entrance panel unit and engage in distributed, peer-to-peer communications and control.
