Appl. No.:

09/138001

Inventors:

David N. Horn - Summit NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04M 342

US Classification:

37920201, 37920401, 37920601, 379158

Abstract:

A solution to the music-on-hold problem associated with audio conference calls. The music on-hold-problem occurs when a conferee having music-on-hold puts the conference call on hold, resulting in a continuous stream of music being transmitted to the other conferees. Such a conferee is called an offending conferee. The solution presented herein is to prevent music-on-hold signals emanating from an offending conferee from being passed through an audio conference bridge to the other conferees. This is accomplished, in particular embodiments, by directing a merging/summing subsystem of the audio conference bridge to temporarily stop combining audio emanating from the offending conferee from being combined or merged onto audio channels through which the other conferees communicate on the audio conference. Once the music-on-hold is terminated, the offending conferee can rejoin conference call by sending a signal that directs the merging/summing subsystem to resume the combining of audio signals emanating from the offending conferee onto the audio channels of the other conferees.

Abstract:

A multi-table-based grant generator in accordance with the present invention solves the issue of bandwidth granularity, while maintaining the simplicity of a table approach. The present invention grant generator provides grants of fine granularity for regulation of upstream transmission of cells in an ATM PON. Multiple grant tables having differing bandwidth granularities are linked together through a simple grant distribution mechanism. The grant tables and grant distribution mechanisms can be recursively linked to achieve a number of different granularities. The grant generator of the present invention is based on multiple grant tables with a combination of multiplexers, dividers, and address counters. The grant generator provides both larger and smaller bandwidths for data grants as well as PLOAM grants without large size grant tables. In one exemplary embodiment of the present invention, improved granularity is achieved, where a first grant table is used for one size of bandwidth grant, e. g.

International Classification:

G06Q 99/00

US Classification:

705 80, 705 1, 705 8, 705 30, 705 16

Abstract:

A system for facilitating payment transaction disputes is provided. According to one aspect of the system, a user, such as an issuer, is allowed to use the system to resolve a disputed transaction. Based on information provided by a cardholder, the issuer is able to use the system to retrieve transactional information relating to the disputed transaction reported by the customer for review. When the issuer uses the system to retrieve information relating to the disputed transaction, a case folder is created. The case folder is a repository for storing all the relevant information and documentation relating to the disputed transaction. Using the information retrieved by the system, the issuer then determines whether to initiate a dispute. Alternatively, the system can also be used by an acquirer to respond to a dispute, usually on behalf of one of its merchant. If a dispute is responded to, a questionnaire is then created by the system.

US Classification:

705 1, 705 26

Abstract:

A comprehensive electronic business support system comprises three layers: (1) the business layer, including various smart components which unify data and business processes across all customer interactions; (2) the integration layer, including various communications messaging interfaces and enterprise application integration adapters, which provide a flexible, automated, and process driven solution for integrating across business applications and operations support systems; and (3) the presentation layer, including various customer views, which are presented via particular business portals. A smart component server provides the core services and comprehensive business process logic required to successfully conduct business online. The communications messaging interfaces integrate with back-office systems for functions such as billing, provisioning, and interconnection.
