Abstract: A telecommunications system for providing telecommunication services to a plurality of users connected to a loop-through cable distribution architecture. The system includes a signal collection and transmission circuit or headend circuit for collecting and transmitting telecommunication signals to the user. In addition, the system comprises a signal distribution system or circuit operatively connected to the signal collection and transmission circuit for receiving and transmitting telecommunication signals therefrom and thereto. The system includes a user or customer interface device operatively connected to an associated signal distribution circuit for both receiving telecommunication signals from the associated signal distribution circuit and transmitting telecommunication signals to the associated signal distribution circuit. The signal distribution circuit is formed by a node having a plurality of output lines and a service module operatively connected to one of the node output lines.

Abstract: A cable distribution system with distributed architecture that can accommodate both digital and analog subscribers. Each home has at least one Room Interface Unit (RIU), one for each television. There is a local service module associated with a group of RIUs (e.g., one for every ten RIUs). There is also a local headend in the vicinity. The local headend has a block of integrated tuner/receiver/decoders that can be controlled to tune in a selected video channel. The selected video channels and a group of standard channels are multiplexed and sent to the local service modules where a group of programmable converters (one for each RIU) place the channel selected by its corresponding RIU at a predetermined frequency. Each of the RIUs associated with a particular local service module receive the corresponding channel. Depending upon whether the subscriber has subscribed to digital or analog service, they will have either a digital or an analog RIU.

Abstract: A cable distribution system with distributed architecture in a multi-dwelling unit or building(s). Each dwelling has at least one Room Interface Unit (RIU), one for each television. There is a local service module associated with a group of dwellings/RIUs (e.g., one per floor). There is also a local headend in the vicinity or in the building or set of buildings. The local headend has a block of integrated receiver/decoders which can be controlled to tune in a selected video channel. The selected video channels and a group of standard channels are multiplexed and sent to the local service modules where a group of programmable converters (one for each RIU) place the channel selected by its corresponding RIU at a predetermined frequency. All of the RIUs associated with a particular local service module can receive a single multiplexed signal and each RIU uses bandpass filtering to select its selected channel. Forward and return DOCSIS channels are also provided.
