Abstract
Abstract A graphically configurable method and device for testing high-frequency (DS0, DS1, DS3, and SONET) communication networks is disclosed. The foregoing is accomplished by a microprocessor controlled test instrument configured through a graphical interface which selects signal paths and test parameters. The graphical interface intelligently presents the choices of paths and test parameters relevant for the current test configuration.
