  • Method and system for diagnosing and testing modems and intermachine trunks
    Patent number: 6370230
    Abstract: A method and system for testing trunks and modems of communication lines includes identifying a trunk and a modem in a communication line from trunk signaling (SS7) data. Historic performance data of the modem in the communication line is then measured. The historic performance data includes the time the modem is connected with the trunk, the speed at which data is communicated through the modem and the trunk in the communication line, and the rate at which the modem connects with the trunk. The performance data of the modem is then correlated with the trunk signaling data to associate the performance data of the modem with the trunk in the communication line. The performance data of the modem is then analyzed to determine if the communication line is operating improperly. The analysis is performed to determine whether the trunk or the modem is operating improperly.
