  • Patent number: 7983179
    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.

  • Patent number: 7779100
    Abstract: Access to network elements of a telecommunications network is integrated through a common access point by an integrated access application which receives a request for communication with a network element. An element management system (EMS) group, including at least one EMS server, associated with the network element is identified. The at least one EMS server is queried to identify an active EMS server and to determine whether the active EMS server has an available connection sufficient to support the request. When the active EMS server has the available connection, the request is sent over the available connection. When the active EMS server does not have the available connection, the request may be buffered and, after a predetermined time, it is again determined whether the active EMS server has the available connection. When the request is sent, it may be multiplexed with other requests over the same available connection.
