    In cable systems with augmented channel capacity, the local oscillators of TV receivers can cause interference between neighbouring subscribers. To avoid the interference, channel off-setting techniques are in effect in cable systems and standards for maximum receiver local oscillator leakage are being implemented. A study, based on a two-subscriber model and on the removal of channel off-setting, has been undertaken to evaluate the maximum overall probability of occurrence of local oscillator interference.

    This paper describes how a Microprocessor can be used to monitor the performance of an ultra low distortion Feedforward Super Trunk Amplifier System. The method described is capable of detecting changes in the loop cancellation of a Feedforward stage that may be caused by deterioration in the hybrid IC. A reduction in the loop cancellation of a Feed-forward stage results in an increase in the distortion level. Through the use of a Head-End Micro Conputer, a signal is sent to a transponder located in each amplifier station which in turn interrogates each RF hybrid IC in the individual Feedforward Amplifier Stages. The relative degree of loop cancellation is indicated at the end of the cascade by monitoring the amplitude of a tone which is generated by introducing modulation into each RF hybrid IC. This tone is observable on any umodulated carrier used for test purposes. View full abstract»

    The findings outlined in this paper are the result of tests undertaken by a joint committee of the Canadian Cable Television Association and the Departmeht of Communications to determine the visibility threshold for composite triple beat under various conditions. The test results, which are discussed in detail, are used to establish a tentative specification and measurement method for carrier-to-triple beat ratio (CBR). View full abstract»

  • Comparison of Technology and Capital Costs for New Home Services

    This paper compares on a per subscriber basis the capital cost requirements of several new home services provided via a number of delivery system alternatives. The study was limited to alarm monitoring, electronic information, messaging, energy load management and pay-TV services, since it is expected that these services will play an important role among new telecommunicatin services offered to homes during the 1980' s. Since the role and penetration of new network architectures and technologies in the local distribution plant during the 80's is uncertain only existing off-air broadcast, telephone and coaxial cable networks and their suitably augmented versions have been considered as delivery network alternatives.

  • Technological Inspiration for New Services: Optical Systems Technology

    This paper is in five parts, excluding the introduction and conclusions. Section 2 examines technical status and the characteristics of fiber components. Section 3 recounts the results of an interrogation of the operators of current fiber optic systems. The intent is to tell the prospective user of the lessons learned by the experienced users. Sections 4 and 5 address the question of fiber economics, the first dealing with the forces of the learning curve phenomenon, the second giving the results of price surveys and cost trends as a function of capability. Finally, the last part alluded to is a brief glossary of terms used in this paper but probably not well understood by the typical CATV operator owner. View full abstract»
