    Abstract: A method and apparatus for storing and communicating information regarding the condition of signals which pass through the network interface between customer premises equipment and a local exchange carrier in a telecommunications system. Information stored at the network interface can be sent as a message which is encoded within the payload, within the frame bits, or within the data link. The information that is stored at the network interface is sectionalized to reduce the amount of information that need be sent and to reduce the processing required by the receiving device.
