標(biāo)準(zhǔn)簡介

Gives performance and safety requirements for the reverse path of wideband cabled distribution systems employing coaxial feeders applicable to reverse paths that will carry amplitude modulated PAL colour television signals conforming to CCIR system I complete with their associated sound signals, and to signals that will be delivered to the head end from a designated input point for distribution downstream on that same cabled distribution system, or for extension to a point outside the system. Qualifies performance limits. Excludes the performance requirements for input interface equipment.
