ABSTRACT:
The upstream performance characteristics of a network are measured by looping a signal through both the downstream and upstream paths of the network. Test equipment may be located at a headend of the network and configured to transmit a signal downstream to a remotely located loopback device that redirects the signal in the upstream path to the test equipment. The upstream characteristics may be predominant in the analysis of the return signal because the downstream path may be relatively free from noise.
