Abstract
There is provided an improved subscriber carrier system which enables the transmission of both voice frequencies and carrier frequencies by a common line without the need for a battery at the subscriber carrier terminal to supply power for the subscriber carrier electronics. A high voltage power supply is utilized to supply power, both for the voice frequency terminal and the subscriber carrier terminal. Loop supervision circuitry is isolated from the power supply. Ringing signals are detected and regenerated at a frequency to pass through the isolation circuit.
