Abstract
A signal-amplifying telephone carrier repeater which is automatically self-adjusting for both cable length and cable gauge in a plural channel, frequency division multiplexed, amplitude modulated carrier system. Also disclosed herein is a subscriber power supply which delivers sufficient power to the subscriber terminal load despite variations in load current due to changes in the number of channels in the carrier system. The power supply also has a back-up unit which operates to deliver power to the load in the event that a fault occurs in the primary supply.
