Abstract
A method and apparatus for modifying a telephone network to create a local area network over telephony (LAN/T) communication system network is disclosed. By employing special coupler/filter arrangements that allow broadband communication signals to pass but preclude telephony signals from passing, a network of multiple telephony lines carrying separate telephony signals can be integrated into a single broadband network without interfering with ongoing telephony traffic.
