Filed:

Sep 12, 1996

Appl. No.:

08/713027

Inventors:

Derek J. Nelson - San Diego CA
Paul R. Hartmann - Escondido CA
Edward S. Tyburski - Carlsbad CA

Assignee:

Applied Digital Access, Inc. - Dover DE

International Classification:

G01R 3108

US Classification:

370249, 370252, 370470, 370526, 379 2602, 379 2701

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 âSectionalizer Reportâ. In preparing the Sectionalizer Report, the information output from a filter is used to determine where particular Events originated.

International Classification:

H04L 700

US Classification:

375372

Abstract:

A DS3 level access, monitor and test system for a telephone network. The system provides selective, and hitless, bit overwrite in any of the embedded DS1, DS0 and subrate channels in a DS3 signal. Multiple DS0 and subrate channels can be tested via the asynchronous time slot interchange in conjunction with the recombiner of the present invention. The present invention further includes a lookahead reframer for framing to the DS3 signal. The present invention also includes a facilities data link (FDL) handler for capturing the FDL channel data in every DS1 channel in a DS3 signal. A high speed bit-for-bit compare is interfaced to a protect path to provide 1:1 fault protection in the system of the present invention. Full time performance monitoring on DS1 and DS3 signals is performed by a shared resource. The system of the present invention provides an integrated approach to synchronization measurement and relative synchronization.

Abstract:

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.
