Abstract
Abstract A telemetry system connects with a telephone system for communication of data via subscriber telephone lines to a provider of data services. Connection of multiplexing circuitry to a set of subscriber lines is accomplished at a main distribution frame by adapters or access blocks set between arc suppressors and a terminal block. The multiplexing circuitry is activated by signals of a line scan unit which, in turn, cooperates with a host computer associated with a station wherein data is processed. The data may be transmitted out of voice band, if desired, to enable simultaneous voice and data transmission. Passive, active and interactive data can be transmitted by the telemetry system. The host computer selects which of a plurality of stations is to be coupled to which of a plurality of subscribers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
195 words
A telemetry system utilizing subscriber telephone lines of a telephone system, said subscriber telephone lines, at one end thereof, connecting to a subscriber premise; said system comprises: at least one subscriber premise equipment, each said subscriber premise equipment being addressable via said subscriber lines; means for interconnecting a flow of data on a plurality of said subscriber lines to a single transmission line; means for providing a communication link between said subscriber lines and said interconnection means without interference with existing telephone system services whereby said interconnection means can communicate with said subscriber premise equipment; and a plurality of computers, said computers being coupled to said interconnection means via said single transmission line and to a plurality of service providers, said computers being interconnected to a common data bus, each said computer being responsive to instructions received from one of said service providers for generating command signals to said interconnection means, said interconnection means thereby providing a data path between said single transmission line and one of said subscriber lines designated by said command signal from said one computer whereby said service providers of each said computer can address said subscriber premise equipment associated therewith.
Claim 2
Dependent Claim
195 words
A telemetry system utilizing subscriber telephone lines of a telephone system, said subscriber telephone lines, at one end thereof, connecting to a subscriber premise; said system comprises: at least one subscriber premise equipment, each said subscriber premise equipment being addressable via said subscriber lines; means for interconnecting a flow of data on a plurality of said subscriber lines to a single transmission line; means for providing a communication link between said subscriber lines and said interconnection means without interference with existing telephone system services whereby said interconnection means can communicate with said subscriber premise equipment; and a plurality of computers, said computers being coupled to said interconnection means via said single transmission line and to a plurality of service providers, said computers being interconnected to a common data bus, each said computer being responsive to instructions received from one of said service providers for generating command signals to said interconnection means, said interconnection means thereby providing a data path between said single transmission line and one of said subscriber lines designated by said command signal from said one computer whereby said service providers of each said computer can address said subscriber premise equipment associated therewith.
Claim 3
Dependent Claim
53 words
A system according to claim 1 wherein each of said subscriber premise equipment has data communication equipment connected to an individual one of said subscriber lines, said equipment including a modem addressable by a signal from said data interconnection means for transmitting a class of data selected by said data interconnection means signal.
Claim 4
Dependent Claim
25 words
A system according to claim 2 wherein said data interconnection means signal is activated in response to a command signal from one of said computers.
Claim 5
Dependent Claim
19 words
A system according to claim 3 wherein said communication equipment transmits utility data provided by meters combined with encoders.
Claim 6
Dependent Claim
16 words
A system according to claim 3 wherein said communication equipment transmits or receives a control signal.
Claim 7
Dependent Claim
22 words
A system according to claim 3 wherein said communication equipment is adapted for the exchange of said service provider and said subscriber.
Claim 8
Dependent Claim
50 words
A system according to claim 1 wherein said communication link providing means is positioned on a main distribution frame of said telephone system and provides a connection between said data interconnection means means and individual ones of said subscriber lines without interference with existing wiring of said main distribution frame.
Claim 9
Dependent Claim
27 words
A system according to claim 1 wherein said communication link providing means includes interconnecting one of said computers to an existing test trunk of said telephone system.
