Covers the transparent return path of cable networks in the frequency range 5 MHz to 65 MHz, or parts thereof. Fibre based networks may use higher frequencies. Active return paths usually only carry return signals, but a passive return path may be used for return and forward signals. Basic procedures are laid down for measuring signals used in return paths so as to assess performance of those signals and their performance limits. Requirements refer to performance limits obtained between the reference points of the return path system. The network termination close to the subscriber is one reference point. If no termination point exists, the system outlet is the reference point
