Abstract:
A local loop interceder for electrically coupling a central office switched telephone network, a high speed data communication device, and a local loop to facilitate voice and high speed data communication, comprising:a switching mechanism having a first position and a second position, said switching mechanism defining a first signal pathway when in said first position, and a second signal pathway when in said second position; said first signal pathway disposed to selectively couple the local loop to said central office switched telephone network; said second signal pathway disposed to selectively couple the local loop to said high speed data communication device; a line activity detector electrically coupled to said first signal pathway, said line activity detector adapted to sense an incoming telephone call from said central office switched telephone network; a control signal detector electrically coupled to said local loop, said control signal detector adapted to sense at least a standard 4 KHz telephone signal and a high speed data communications signal on said local loop; and a control bus electrically coupled to said switching mechanism, said control signal detector, and said line activity detector, said control bus being adapted to facilitate electrical communication between said switching mechanism, said control signal detector, said line activity detector, and an external control mechanism, such that when said incoming telephone call is sensed said switching mechanism defines the first signal pathway, such that when said standard 4 KHz telephone signal is sensed said switching mechanism defines the first signal pathway, such that when said high speed data communications signal is sensed said switching mechanism defines the second signal pathway, and such that when the local loop is selectively coupled to one of said first signal pathway and said second signal pathway, communications over the nonselected pathway is prevented.
