Appl. No.:

10/328577

Inventors:

Ali M. Cherchali - Jackson NJ, US

Assignee:

AT&T Corp. - New York NY

International Classification:

H04M 1100

US Classification:

379 9305, 379 9001, 37922113

Abstract:

An architecture and technique for creating self-installable and portable telephony (dial tone) service that can be moved between any two locations that has access to both a voice communication network and a data network. A telephony adapter is used as a subscriber premises device that is connected between a conventional telephone set and both a voice network and a data network. A provisioning server communicates with the telephony adapter through the data network and maintains a record of the subscriber's local telephone number and IP address of the telephony adapter. As the subscriber moves from one location to another, the telephony adapter (once turned “on”) will communicate with the provisioning server and re-establish phone service, always using the same local phone number of the subscriber.

H04J 1/02
H04L 12/56

US Classification:

370468, 37039541, 370493

Abstract:

A communication system includes a plurality of devices, such as cable modems, in communication with a station, such as a cable modem termination system, that provides efficient upstream bandwidth sharing.

Appl. No.:

11/033930

Inventors:

Ali Cherchali - Jackson NJ, US
William G. Lester - Cranford NJ, US
Robert J. McLaughlin - Allentown NJ, US

Assignee:

AT&T Corp. - New York NY

International Classification:

H04L 12/56

US Classification:

370389, 370400, 709202

Abstract:

In an arrangement where the device that is known to an ISP is communicating with the ISP through an interposed device that is not known to the ISP, the interposed device captures the known device's MAC address upon startup and clones the captured MAC address in all standard packets that it sends to the ISP.

International Classification:

H04M 1/64
H04L 12/66
H04L 12/50

US Classification:

379 8817, 370356, 370359

Abstract:

An improved telephony adapter compresses voice data, creates IP packets, and prioritizes the voice IP packets over the data IP packets. Preferably, the compression and packetization interval is such that the bandwidth occupied by the voice IP packets is approximately half of the minimum average available bandwidth in the upstream direction, thereby maintaining acceptable latency and voice quality of the speech. Further enhancement is achieved by causing the ISP to also give priority to voice packets that are destined to the telephony adapter, over the data packets that are destined to the telephony adapter.
