Abstract
A system and method are disclosed for determining a level of quality of a communications medium having an indeterminate delay. The communications medium communicatively couples a transmitting station and a receiving station. The transmitting station transmits over the communications medium a measurement sequence including a synchronization sequence followed by a measurement sample. The transmitted measurement sample has a predetermined beginning point, which is identified by the transmitted synchronization sequence. The receiving station receives over the communications medium the measurement sequence including the synchronization sequence followed by the measurement sample. The receiving station determines from the received synchronization sequence the beginning point of the received measurement sample. The transmitted measurement sample and the received measurement sample are then compared according to respective beginning points to determine the level of quality of the communications medium.
