ABSTRACT:
A loop-powered T1 digital radio is coupled to a powered T1 wireline. The radio not only interfaces digital T1 communication signals with the line, but is configured to extract and convert electrical power from the line to voltages necessary for operating the radio. The loop-powered T1 radio transmits and receives RF energy containing the T1 digital communication signals with respect to a remote digital radio, such as a ‘blue tooth’ type radio.
