Description of the Book:

Bi-directional cable TV (CATV) systems that are being installed today may not be well suited for computer communications. Older CATV systems are being modified to bi-directional transmission and most new systems are being built with bi-directional capability included. The extreme bandwidth requirement for carrying 20 or more TV channels on a frequence-division multiplexed (FDM) basis requires cables to be equalized and provided with repeaters for operation at comparatively high frequencies. The latest CATV systems provide down stream, to-the-subscriber transmission between 50-300 MHz, and up stream from-the-subscriber transmissions between 5-30 MHz. This system design is adequate for TV. However very little data communications experience has been accumulated on CATV; and because of system noise and the absence of system redundancy, reliability in computer communications on CATV may become a major problem.
