5 <br /> TECHNICAL SYNOPSIS <br /> Cablevision of Durham operates the cable television distribution <br /> network in Durham County, and proposes to construct and maintain <br /> plant in the rural residential areas of Orange County that are <br /> adjacent to its existing plant, or that may become economically <br /> feasible in the future. <br /> The existing distribution network covers nearly 1,000 miles of <br /> cable plant. It is comprised of RCA and C-Cor active <br /> electronics, .750 trunk cable, .500 feeder cable and passive <br /> devices manufactured by Magnavox, Jerrold and C-Cor. The band- <br /> width of the core system is 270 MHZ. New line extensions are <br /> „designed for 400 MHZ feeder distribution to facilitate possible <br /> future channel capacity upgrade. <br /> Signals originate at a headend site on Ellis Road in Durham <br /> County, just south of the Durham Freeway. This location is the <br /> heart of the technical operation of the system. Signals will be <br /> transported from the headend to a central hub by way of <br /> fiberoptic cable. Additional fiberoptic hub sites are planned <br /> for the near future. The fiber hub network will be capable of <br /> distribution of an expanded bandwidth, thus facilitating future <br /> channel expansion. The fiberoptic terminal equipment is <br /> provided by AT&T under the trade name of "Laser Link" . This <br /> equipment uses amplitude modulation, thus providing a relatively <br /> economical means of using fiberoptic technology. The fiber is <br /> manufactured by AT&T and Alcatel through a partnership with Comm <br /> Scope. <br /> The fiberoptic hub network reduces the excessively long <br /> amplifier cascades to improve picture quality and signal reli- <br /> ability. This permits the extension of service to more remote, <br /> distant areas than was previously technically feasible. <br /> The coaxial distribution system is two way capable. All service <br /> taps are directional. Standby powering is used at critical <br /> locations, and at points that have historically experienced <br /> problems with commercial power interruptions. <br /> Cablevision of Durham strictly complies with all regulations <br /> concerning safety as mandated by the Occupational Safety and <br /> Health Administration, Department of Transportation rules and <br /> the National Electric Code. <br />
