Abstract: In the early 1950s Northeastern Gas Transmission Company, a subsidiary of Tennessee Gas Transmission Company, started building a pipeline into the New England area. During the early years of operations the dispatching center controlled the system strictly by pressure points that were called in by operator at remote compressor stations. As there were more pipeline and sales stations added to the system there became a greater need for more control by ths dispatcher. At that time telemetry was just starting to be used in the pipeline industry and was very basic in that individual readings wers arriving at ths dispatching center on separate telephone circuits. Then Multiplexing Telemetering came into use and several Telemetering readings came into use on one telephone circuit and opened the door of our present supervisory control systems that are still in use today.
