Apparatus, systems and methods for isolating adsl signals from pots signals

Abstract

An apparatus for isolating ADSL signals from POTS signals includes a single low pass filter for filtering the POTS signals for all POTS terminal devices within a customer's premises. The low pass filter is mounted within a line isolation device (LID) connected between a telephone jack and an ADSL transceiver. The customer's wiring is altered so that the ADSL and POTS signals are supplied to blue (B) and yellow (Y) lines, rather than the typical connection to the red (R) and green (G) lines, and the LID returns filtered POTS signals on the R and G lines. The telephone jacks within the premises remain connected to the R and G lines and receive the filtered POTS signals from the LID. Instead of reconnecting incoming signals to the R and G lines upon removal of the ADSL transceiver, a jack is preferably used which automatically shorts the B and Y lines to the R and G lines, respectively, upon removal of the LID from one of the telephone jacks. A wall-mounted connector for coupling with the LID includes a pair of shorting bars. When the connector for the LID is inserted into the jack, a set of coupling members for making connections between the connectors are moved away from the shorting bars and are electrically isolated from each other. When the LID connector is inserted into the jack, each shorting bar contacts a pair of coupling members, thereby shorting the B and Y lines to the R and G lines, respectively.
