Claim One:
1. A method for producing service quality metrics related to the communications of a plurality of voiceband modems or fax machines communicating on a packet communication channel, the method being performed by a service quality monitor and comprising the steps of: a) monitoring said packet communication channel to determine a burst length; b) monitoring said packet communication channel to determine a gap length; and c) calculating a performance metric for said monitored communication channel based on said monitoring steps, wherein said performance metric is selected from a Reliability Factor, a Tlost metric, and a Throughput Factor, and wherein said calculating step further comprises the steps of: i) monitoring the density (“Gden”) of packet loss within said gaps; ii) monitoring the retrain time of one of said plurality of voiceband modems or fax machines; iii) monitoring the Packetized Device Transmission Speed (“PDTS”) of said one modem or fax machine; iv) comparing said burst length to a retrain wait time of said one voiceband modem or fax machine; and v) determining said Tlost metric; and wherein said service quality monitor comprises an electronic device programmed to perform the method.
