An integrated filter and modular jack for filtering a voice signal delivered over a digital subscriber line between a first communication circuit and a second communication circuit where the voice signal includes analog and digital portions. The modular filter jack includes a connector for receiving the voice signal from a first communication circuit, a high pass filter, and/or a low pass filter. The high pass filter includes a capacitor operatively associated with the connector to block the analog portion of the voice signal while passing the digital portion. The low pass filter includes an inductor operatively associated with the connector to block the digital portion of the voice signal while passing the analog portion. The modular filter jack also includes a receptacle operatively associated with the high pass filter and/or the low pass filter for receiving a connection element to make electrical contact between the first and second communication circuits.
