ABSTRACT:
A method and apparatus for automated sectionalization of a DS1/DS3 data path based upon information received at a single location along the path. A test and monitor device is located at a point of demarcation between an LEC and an IEC. A Remote Module is located at a point of demarcation between the LEC and CPE. The test and monitor device is fully ANSI compatible. The information that is received is processed in a three step process in order to generate a "Sectionalizer Report". In preparing the Sectionalizer Report, the information output from a filter is used to determine where particular Events originated. An Alarm Indication Signal-Customer Installation signal is generated to enhance the ability to sectionalize the data path.
