14 <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 P.oad 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 />
