US Patent:

6687231, Feb 3, 2004

Filed:

Nov 30, 1999

Appl. No.:

09/450714

Inventors:

Richard Marion Czerwiec - Raleigh NC
Richard Roger Rzonca - Raleigh NC
Marlin V. Simmering - Clayton NC
Geert Van Wonterghem - Eeklo, BE
Jan De Groote - Berchem, BE

Assignee:

Alcatel - Paris

International Classification:

G01R 3108

US Classification:

370244, 370228, 370245, 370250

Abstract:

A system and method for enhancing reliability in a communication system. In the system and method, redundant signal paths are continuously tested to determine if any faults are present while the operating signal paths are in use. If any faults are present in the redundant signal paths, they can be addressed while the operating circuits are still in use. This minimizes the chance that a switch from an operating signal path to a redundant signal path because of a fault in the operating circuit will result in downtime.

International Classification:

H04M 1100

US Classification:

370354, 370216, 370228, 379 905

Abstract:

Disclosed are systems and methods for transferring data between servers and subscribers. A central office employs DSL circuit cards. Each DSL circuit card encodes a digital signal using a discrete multitone technology (DMT) scheme, and sends an encoded signal on a subscriber line. A disclosed architecture allows the functions of a faulty DSL circuit card to be assumed by another card, without substantial disruption of subscriber service. Further, the architecture allows the faulty DSL to be physically replaced, with minimal disruption of subscriber service. Another aspect of the architecture allows for the testing of subscriber lines.

International Classification:

H04L 12/66

US Classification:

370463, 370493, 375222, 379 9301

Abstract:

An xDSL (x-Digital Subscriber Line) signal is multiplexed with POTS on a twisted pair between a subscriber modem and line termination equipment in a shelf that also includes network termination equipment for connection to a broadband network. The line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. Separate lowpass filters are provided at each end of a twisted wire pair between the shelf and each subscriber equipment. A shelf can be used as a hub for connecting to a remote shelf that includes the line termination equipment for connection to subscribers.

Abstract:

A telecommunications rack has one or more shelves connected to a narrowband network and to a broadband network for serving a plurality of subscribers. Line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. One half of a redundant equipment pair can be placed in one shelf and the other half in another shelf in a same rack for sharing network termination equipment between such shelves. The rack or shelf in the rack can be used as a hub for connecting to a remote shelf or housing that includes the line termination equipment for connection to subscribers.

US Classification:

370463, 370352, 361797

Abstract:

A shelf or housing is connected to a narrowband network and to a broadband network for serving a plurality of subscribers includes two sections, one for lowpass filters and another for line and network termination cards. The line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. The shelf or housing can be used as a hub for connecting to a remote shelf or housing that includes the line termination equipment for connection to subscribers. Although the internal bus of the shelf or housing is shown in a non-redundant embodiment, an increased level of equipment protection can be provided by placing one half of a redundant equipment pair in one shelf or housing and the other half in the other shelf or housing and sharing network termination equipment between such shelves or housings.

US Classification:

3703951, 37039551

Abstract:

Asynchronous Transfer Mode (ATM) cells are conveyed over a shelf bus to and from an NT (network termination) card inserted into the bus connected to an ATM network and to a plurality of LT (line termination) cards also inserted into the bus, wherein the NT card processes the ATM cells and provides downstream cells to the bus with a guard byte and upstream cells to the ATM network without a guard byte.
