Enhanced security communication system
First Claim
1. A telecommunication system for providing telecommunication services, including video, telephony and computer network services, to a group of end user sites connected to a loop-through cable distribution system, comprising:
- a headend system which provides said telecommunication services in the form of telecommunication signals, said telecommunication signals comprising a video signal;
a service module in communication with said headend system and adapted to receive said telecommunication signals from said headend system and provide said telecommunication signals from said headend system to said group of end user sites, said service module comprising;
processing means for processing telecommunication service requests from said end user sites;
splitting means for receiving said video signal from said headend system and splitting said video signal into a plurality of video signals, one for each of said end user sites;
channel formatting means for each of said end user sites, said channel formatting means for receiving one of said plurality of video signals, extracting a video channel from said one of said plurality of video signals, said video channel being requested by one of said end user sites, demodulating said video channel from its modulated frequency to baseband, and creating an output video channel for said one of said end user sites by remodulating said video channel from baseband to a predetermined frequency, said predetermined frequency being different for each of said end user sites summing means for summing said output video channel from each of said channel formatting means into a composite video signal comprising each of said output video channels modulated to different frequencies;
a loop-through cable communication connection which communicates said composite video signal from said summing means to each of said end user sites;
coupling means for coupling said communication connection to an end user site;
filter means for filtering said output video channel for said end user site from said composite video signal, creating an end user video signal; and
a customer interface device which receives said end user video signal and transmits said end user video signal to a video signal viewing apparatus;
wherein there are N number of end user sites and N number of corresponding channel formatting means, and wherein X represents a particular end user site and channel formatting means and X can vary from 1 to N, such that a particular channel formatting means X creates said output video channel for end user site X at a frequency associated with channel M, wherein M=X+1; and
wherein said end user site 1 is furthest from said service module and end user site N is closest to said service module.

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. The service module further includes a signal splitter having a plurality of output lines, a user service module circuit operatively connected to one of the splitter output lines, and a processor control circuit operatively controlling the service module.
