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.
