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. A Remote Alarm Indication-Customer Installation signal is generated to enhance the ability to sectionalize the data path.

An improved network interface unit (NIU) for remotely monitoring and testing the performance of DS1 telephone circuits, installed on the network side of an interface between customer premises equipment (CPE) and equipment provided by the network provider. The inventive NIU is used to non-intrusively collect and transmit full-time performance monitoring data to the network provider. The inventive NIU provides continuous and non-intrusive performance monitoring of DS1 transmission systems. With the inventive NIU installed at the interface between the customer's CPE and the LECs' equipment, network service providers are alerted to potential problems before they adversely affect the service provided by the network providers to their customers. The inventive NIU enables a network service provider to quickly and non-intrusively determine whether a problem exists in the equipment provided by the network provider or in the equipment on the customer's premises. The inventive NIU, therefore, advantageously eliminates false dispatches and expensive and unnecessary troubleshooting required by prior art network interface units. The inventive NIU provides nonintrusive monitoring of CPE by facilitating the conversion of CPE-generated signal frame formats to the Extended Superframe Format (ESF) (according to the ANSI T1.403 Standard with Performance Report Message). The present invention performs an adaptive real-time DS1 circuit frame format conversion.
