  • Signal coupler with automatic common line attenuation compensation
    Patent number: 5627501
    Abstract: The present invention relates to a for coupling Plain Old Telephone Service (POTS) signals and Asymmetric Digital Subscriber Line (ADSL) signals to a common line (TL). In order to avoid saturation of inductances (L1,L2,L3,L4) of a low pass POTS filter (LPF) located between the POTS transmitter/receiver (PTR) and this common line (TL) when the POTS signal is not sufficiently attenuated by this common line (TL), a variable impedance (SL) is inserted between the POTS transmitter/receiver (PTR) and this low pass POTS filter (LPF). The value of this variable impedance (SL) is controlled by a control signal (CS) supplied by the ADSL transmitter/receiver (ATR) which measures the attenuation caused by this common line (TL).
