Abstract
A method and apparatus for implementing a communication network for well monitoring and control applications where a twisted pair cable bus is used to connect well-related locations. The twisted pair cable bus will exhibit high parallel impedance when used in differential mode and low series impedance in common mode. A bus supervisor and devices connected at nodes can exchange signal transmission. Communication, including data and control, signals and power signals can circulate along the twisted pair cable bus among and between the connected devices.
