Apparatus for converting a local POTS network to VoIP capability includes a signal controller that is adapted for connection between a broadband-enha nced POTS service point and the local network for reducing POTS signaling. T he apparatus is, for example, a high pass filter that includes a first port for receiving broadband-enhanced POTS service and a second port for sending DSL signals to the local network. The high pass filter can be connected to b roadband-enhanced POTS service at a Network Interface Unit of a DSL subscrib er location. Preferably, the high pass filter has a frequency response range that is capable of greatly reducing or eliminating a POTS service loop volt age and/or baseband voice signals on the local network.
