摘要： A method includes receiving user data packets from customer premises equipment (CPE) in communication with a network terminal over a communication link and enabling a network terminal-side loopback mode to establish a closed traffic test loop across the communication link between the network terminal and the CPE. The received user data packets indicate that a CPE-side loopback mode is enabled. The method also includes injecting a number of data bits into the closed traffic test loop until a saturation threshold of the communication link is satisfied, and when the number of data bits injected into the closed traffic test loop satisfies the saturation threshold, determining a packet error-rate of the number of data bits circulating in the closed traffic test loop. After determining the packet error-rate, the method also includes removing the closed traffic test loop across the communication link between the network terminal and the CPE.
