ABSTRACT:
A low power, low cost distributed digital loop (DDL) carrier system that combines television and voice telephone signal transmission over coaxial cables. The DDL system employs a passive/active tap module (114) that controls the steering of the video and telephone signals. The high frequency down stream telephone signal is not processed until a routing terminator (110) converts it to lower frequency signal for transmission in the lower frequency subsplit channel. The telephone signal is then transmitted back up through the subsplit where the active circuitry of each tap intercepts the telephone signal, selects the needed signal and transmits it down to a network interface unit (120) located at the subscriber premises.
