POTS and xDSL or the circuit driver for POTS/xDSL interface which is integrated

摘要

(57) Abstract The driver circuit (180), in order the next coil which is connected to the subscriber''s loop (106,108) with the secondary winding which is connected to the interface circuit (104) to offer between the transformer and the aforementioned interface circuit and the aforementioned circuit which it possesses specified impedance match, over the specified frequency zone of the aforementioned driver circuit, it has with the feedback circuit which connects the aforementioned next coil to the aforementioned secondary winding. With desirable execution form, as for the interface circuit POTS and ADSL are offered are the line card which is integrated.
