US Patent:

6341158, Jan 22, 2002
Filed:

Nov 7, 1997
Appl. No.:

08/966285
Inventors:

Martin Corso, III - Aurora IL
Nicholas D. De Trana - Addison IL
Craig L. DeCaluwe - Naperville IL
Robert G. Demmert - St. Charles IL
Assignee:

ATT Corporation - New York NY
International Classification:

H04M 124
US Classification:

379 6, 379 5, 379 22, 379 15, 379 9
Abstract:

In a communication network, a method and apparatus is provided to detect the presence of loopback errors over facilities interconnecting switches of the network. According to the test protocol, an originating switch generates a tone on a forward trunk associated with the facility and monitors the return trunk for the presence of that tone. If the return trunk contains the tone, the originating switch fails the facility for a loopback condition. The loopback test protocol complements conventional continuity tests and results in greater reliability of communications networks.

Assignee:

ATT Corp. - New York NY
International Classification:

H04M 342
US Classification:

37921101, 37912701, 37920715, 37921102, 37922101
Abstract:

A method of providing for customer selection of a circuit selection algorithm for use in a public network comprises the steps of storing a plurality of circuit selection algorithms in public network memory, translating a routing number for a call into customer data, matching the customer data with a trunk block circuit selection algorithm and controlling the delivery of calls to a customer in accordance with the trunk block circuit selection algorithm. The customer may also custom design their own circuit selection algorithm and input their custom designed algorithm into public network memory along with others for selection in accordance with their customer criteria, for example, time of day or day of week, low traffic period, high traffic period or other criteria. Apparatus for providing for customer selection of a circuit selection algorithm for use in a public network comprises a public network memory for storing a plurality of circuit selection algorithms and a controller for translating a routing number for a call into customer data, matching the customer data with a circuit selection algorithm and controlling the delivery of calls to a customer in accordance with the circuit selection algorithm. The apparatus preferably comprises a switching center for toll or local call switching.

US Patent:

6700870, Mar 2, 2004
Filed:

Dec 10, 1999
Appl. No.:

09/460319
Inventors:

John D. Brandt - Oldenburg IN
Nicholas D. De Trana - Addison IL
Arthur G. Deacon - Summit NJ
Craig L. DeCaluwe - Naperville IL
Hossein Eslambolchi - Basking Ridge NJ
Assignee:

ATT Corp. - New York NY
International Classification:

H04L 1226
US Classification:

370230, 370235, 370217, 370221
Abstract:

In an ATM network, data loss caused by pre-programmed network optimizations can be reduced or avoided if a record of such optimizations is made, and if, prior to another optimization, some event occurs. The detection of some external event should indicate that another optimization is warranted.

US Patent:

6856674, Feb 15, 2005
Filed:

Dec 23, 2002
Appl. No.:

10/328208
Inventors:

Nicholas D De Trana - Addison IL, US
Craig L DeCaluwe - Naperville IL, US
Hossein Eslambolchi - Los Altos Hills CA, US
Paul Greendyk - Prospect Park NJ, US
David Caswell McChristian - Naperville IL, US
Assignee:

AT&T Corp. - New York NY
International Classification:

H04M015/00
US Classification:

3791142, 37911401, 37911415, 37911416, 37911417, 37914401
Abstract:

The present invention is a method and apparatus for providing prepaid card service to customers for placing telephone calls without relying on a post-service billing model. A service management computer having access to a card database is connected to the network only by out-of-band connections. A voice response unit or a tone receiver and announcement player in the network are the voice interface with the customer and are provided at the originating switch in the network to eliminate multiple switches from the call path.

US Patent:

7061906, Jun 13, 2006
Filed:

Jan 29, 2002
Appl. No.:

10/058031

Assignee:

AT & T Corp. - Bedminster NJ
International Classification:

H04L 12/66
H04L 12/28
G06F 9/46
US Classification:

370352, 3703952, 718105
Abstract:

Telecommunications switching systems that require real-time computer control can be controlled using remotely located computers coupled to the switching systems via data links. By coupling several switching systems to one or more centrally located control computers, maintenance staffing can be reduced while increasing overall system reliability by providing back up control computers in multiple centralized locations. Centrally located control computers can be backed up with redundant computers at the central control site.

Filed:

Nov 1, 2000
Appl. No.:

09/703699

H04L 12/28
US Classification:

370229, 370235, 370389, 370412, 370428
Abstract:

In an IP network, tabulating the number of data packets received from and/or sent to a particular IP address over time can provide a mechanism by which it is possible to determine or predict overloading of a node or nodes in an IP data network. By selectively deleting data packets received from a suspect source address or inhibiting the transmission of data packets to a suspect destination address, network management and control can be readily accomplished.
