ABSTRACT:
A loop circuit interface module enabling a plurality of data terminals remote from each other and from a central controller to communicate with each other and the central controller over a plurality of data channels interconnecting same is disclosed. The loop circuit interface module comprises a plurality of data ports for inputting data from either the loop controller or another loop circuit interface module. The data ports also output data to the loop controller or another loop circuit interface module. The module has a plurality of signal ports for inputting data from the data terminal and for outputting data to the data terminal. A bridging means provides a matched impedance between the loop circuit interface module, the loop controller, and the data terminals. The bridging further provides gain to the data at the plurality of ports. Switching means selectively and controllable connects the plurality of data ports and the plurality of signal ports directly to each other, or to each other through the bridging means.
