ABSTRACT:
The invention relates to a system for end-of-line monitoring of HFC networks by using a main tuner dedicated to receiving measurement requests from a network monitoring server via a DOCSIS downstream channel, and an auxiliary tuner used for the purpose of performing measurements of the downstream channel by analogue and digital measurement circuits. A cable modem is used to transmit measurement results to the server over a DOCSIS upstream channel. The addition of the auxiliary tuner, permits faster measurements to be performed by the EOL monitoring system and reported back to the server, thereby affording real-time remote testing and diagnostics.
