ABSTRACT:
A communications device can include first and second input terminals configured to provide coupling with respective first and second conductors of a communications line, and first and second signal conductors respectively coupled with the first and second input terminals. A communications circuit can be coupled to the first and second signal conductors wherein the communications circuit provides a communications interface. A test switch can be configured to electrically couple the first and second signal conductors responsive to activation thereof, and an indicator circuit can be configured to provide indication of a completed electrical circuit through the test switch. Related circuits and methods are also discussed.
