Abstract
A modem having reduced power dissipation and temperature compensation. The modem includes a data pump, a telephone line interface, memory and a controller, connected to the memory and the data pump, for executing program code to control transfers between the data pump and a telephone line. The telephone line interface includes a current-limited loop holding circuit in order to limit power dissipated in the modem due to DC loop current. The current-limited loop holding circuit includes a constant current source in series with a DC loop holding circuit.
