Abstract:
1. An end-of-line monitor for real time monitoring the performance of a hybrid network based on Data-Over-Cable Service Interface Specification (DOCSIS), in response to a measurement request received from a remote server, the monitor comprising: a connector for connecting the end-of-line monitor to an RF cable end of line in the hybrid network, and for receiving and transmitting DOCSIS channels via the hybrid network; a first tuner for receiving the measurement request, via a predetermined DOCSIS downstream control channel of the hybrid network, and for remaining in contact with the server to receive other measurement requests; a second tuner tunable to any other downstream channel for receiving signals transmitted on a selected one of the downstream channels in accordance with the measurement request; a measuring device, in communication with the first and the second tuners, for performing the requested measurement on a selected downstream channel; and a DOCSIS cable modem linked to the measuring device, for transmitting results of the requested measurement to the remote server, over a predetermined upstream DOCSIS channel of the hybrid network; wherein, in operation, the server collects and evaluates the measurement results for performing remote end-of-line diagnostics.
