Abstract: A VDSL splitter device adapted to receive a multi-frequency signal that includes a POTS signal portion and a VDSL signal portion and outputs separate POTS and VDSL signals. The VDSL splitter device includes an input port that receives the multi-frequency signal, a POTS output port, and a VDSL output port. The VDSL splitter also includes a POTS signal conditioning network electrically connected to the input port and the POTS output port. The POTS signal conditioning network receives the multi-frequency signal from the input port and outputs the POTS signal at the POTS output port. The VDSL splitter device also includes a VDSL signal conditioning network electrically connected to the input port and the VDSL output port. The VDSL signal conditioning network includes a voltage blocker and a VDSL high-pass filter, and is adapted to receive the multi-frequency signal from the input port and outputs the VDSL signal at the VDSL output port.

Abstract: An in-line filter for use in telecommunication applications wherein both digital data signals and voiceband signals are transmitted on the same telecommunication medium. The inline filter includes an inductive circuit portion, a switchable RC network, and an RLC network. The inductive circuit portion is connected between a pair of ring and tip terminals. The switchable RC network is electrically coupled to the inductive circuit portion, as is the RLC network. The RC network is switchable between an “off-hook” state and an “on-hook” state. The off-hook state presents the RC network in parallel with the RLC network and, thereby, increases the capacitance across the ring and tip terminals. The on-hook state operationally, electrically removes the RC network from the filter and increases the impedance across the ring and tip terminals.
