ABSTRACT:
A system for collecting data from a communications network includes customer premises equipment (“CPE”) for monitoring and storing response data. A CPE data collection module uses a Web-based service to collect information from the CPE and process the information to determine line quality and any errors that may exist on either the WAN side or the LAN side of the communications network, and further determine the root cause based on built-in business rules for trouble shooting customer service. The CPE conducts per-tone diagnostics on the WAN side of the communications network and obtains WAN side data. The CPE obtains response data from devices on the LAN side. Both WAN side data and LAN data may be transmitted substantially in real-time or stored and transmitted periodically to the CPE data collection module upon requests originated from the CPE data collection module.
