Passive distributed filter system and method
First Claim
1. A passive distributed filter for enabling decoupling of first and second simultaneous communications channels on a telephone connection, comprising:
- a first channel filter configured to decouple a first channel from a combined signal having said first channel and a second channel on said telephone connection; and
an automatic control mechanism configured to isolate said first channel filter from said telephone connection when a first channel device connected thereto is on-hook and configured to interface said first channel filter with said telephone connection when said first channel device is off-hook.

Abstract
A plurality of passive distributed POTS filters (DPF) are associated with a respective plurality of POTS communications devices and decouple a POTS channel from a telephone connection, while permitting and not interfering with a second communications channel (e.g., DSL, ADSL, SDSL, RADSL, VADSL, etc.) on the telephone connection that is utilized by a modem. In architecture, the DPF system includes a plurality of POTS communications devices, such as telephones, and a plurality of the DPFs corresponding respectively with and connecting each of the POTS communications devices to the telephone connection. Each of the DPFs comprise an automatic control mechanism and a POTS filter. The automatic control mechanism is configured to isolate the POTS filter when a respective POTS communications device is on-hook. Each DPF is configured to permit POTS communications over a POTS channel on the telephone connection with the respective POTS communications device when the POTS communications device is off-hook. Furthermore, a second communications device, such as a DSL (e.g., ADSL, SDSL, RADSL, VADSL, etc.) communications device, is connected to the telephone connection and communicates signals over a second channel. The POTS and second channel are communicated over the telephone connection concurrently without appreciable interference.
