Patent ID: 7508817

Claim:
An IP (Internet Protocol) diagnostic system for measuring data transport quality over an Internet Protocol operating in a communication system, comprising: one or more processors each placed at different segments in the communication system, wherein each of said processors is programmed to: receive a request to establish a test session with a corresponding test node; establish one or more IP connections with the test node; carry out the test session with the test node on said IP connections; and measure a quality level for each of said IP connections, wherein the quality level is measured according to at least one of a group of metrics comprising delay, jitter, packet loss, echo, audio clarity, and Perceptual Evaluation of Speech Quality, wherein the test node is a IP terminal unit, and wherein the processor is further programmed to instruct the IP terminal unit to Prevent insertion of data signals therefrom on the one or more IP connections during execution of the test session.
