    摘要： 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.

    摘要： Determination of the location of an error condition or a failure includes receiving at a network interface a first framed digital signal from customer premises equipment, and determining whether the first framed digital signal indicates a failure. Overhead bits are modified in the first framed digital signal to generate a second framed digital signal, such that the modification is equivalent to insertion of errors into the first framed digital signal at a bit error ratio (BER) of not greater than a predetermined ratio, if the first framed digital signal indicates a failure. The second framed digital signal is then sent from the network interface in place of the first framed digital signal to indicate that the failure reported by the first framed digital signal is located in the customer premises equipment. Otherwise, if no failure is indicated, the first framed digital signal is transmitted without any modifications.

    摘要： In locating a faulty regenerator, a fault locating filter is used in a T1 or T1C Carrier Repeater Apparatus Case or Office Repeater Bay (ORB) to select the appropriate fault locate sinusoid from the output winding of the repeater. This process uses three different filter types at twelve different frequencies. Conventional filter design requires a different filter for each frequency leading to the need to stock 36 different filters. This patent covers the design of a filter which may be optioned to provide all three types and twelve frequencies within a single unit, reducing the required inventory of such filters by a substantial amount.
