Multicarrier Transmission System With Low Power Sleep Mode And Rapid-On Capability
view source
US Patent:

6445730, Sep 3, 2002
Filed:

Jun 13, 2000
Appl. No.:

09/581400
Inventors:

John A. Greszczuk - Stow MA
Richard W. Gross - Acton MA
Halil Padir - N. Andover MA
Michael A. Tzannes - Lexington MA
Assignee:

Aware, Inc. - Bedford MA
International Classification:

H04B 138
US Classification:

375219, 375220, 375356
Abstract:

A muticarrier transceiver is provided with a sleep mode in which it idles with reduced power consumption when it is not needed to transmit or receive data. The full transmission and reception capabilities of the transceiver are quickly restored when needed, without requiring the full (and time-consuming) initialization commonly needed to restore such transceivers to operation after inactivity.

US Patent:

6522666, Feb 18, 2003
Filed:

Sep 12, 2000
Appl. No.:

09/622486
Inventors:

Michael A. Tzannes - Lexington MA
Marcos Tzannes - Orinda CA

US Patent:

6549520, Apr 15, 2003
Filed:

May 17, 2000
Appl. No.:

09/573816
Inventors:

Richard W. Gross - Acton MA
John A. Greszczuk - Stow MA
David M. Krinsky - Acton MA
Marcos Tzannes - Orinda CA
Michael A. Tzannes - Lexington MA
Assignee:

Aware, Inc. - Bedford MA
International Classification:

H04L 116
US Classification:

370242, 370252, 370271, 370295, 370437, 370485
Abstract:

A modem for use in Digital Subscriber Line communications transmits and receives data over the local subscriber loop in common with voice information over the loop, while avoiding the need for voice/data splitters. The modem responds to disruptions associated with âdisturbance eventsâ such as on-hook to off-hook transitions and the like by rapidly switching between pre-stored channel parameter control sets defining communications over the loop under varying conditions. In addition to changing parameter control sets responsive to a disturbance event, the modem may also change transmission power levels and other system parameters such as frequency domain equalizer characteristics. Further, provisions are made for reduced bandwidth communications under selected conditions.

US Patent:

6775320, Aug 10, 2004
Filed:

Sep 15, 2000
Appl. No.:

09/663001
Inventors:

Marcos C. Tzannes - Orinda CA
Michael A. Tzannes - Lexington MA
David C. Hunter - Winchester MA
Richard W. Gross - Acton MA
Halil Padir - North Andover MA
Assignee:

Aware, Inc. - Bedford MA
International Classification:

H04L 516
US Classification:

375222, 370464
Abstract:

A transceiver and method for communicating over a communications channel having a plurality of subchannels are described. In particular, the transceiver is capable of dynamically switching between communicating data for a first active application set and communicating data for a second different active application set. An active application set is defined as the set of one or more active applications for which the transceiver is currently communicating data. As part of communicating data for the first active application set, the transceiver allocates the subchannels to the one or more applications in the first application set. The transmission requirements of the first active application set defines a first communication state of the transceiver. When the transceiver dynamically transitions to communicating data for the second different application set, the transceiver reallocates the subchannels to the one or more applications in the second different application set. The transmission requirements of the second different active application set defines a second communication state of the transceiver.

US Patent:

7738542, Jun 15, 2010
Filed:

Apr 20, 2005
Appl. No.:

11/109646
Inventors:

Peter N. Heller - Somerville MA, US
Edmund C. Reiter - Lincoln MA, US
Michael A. Tzannes - Lexington MA, US
Assignee:

Aware, Inc. - Bedford MA
International Classification:

H04B 1/38
H04L 5/16
US Classification:

375222, 370254, 370419, 704200
Abstract:

An alternative approach to coping with the ever increasing demand for faster communications hardware is to design modems that are capable of operating its speeds at a higher data rate than a speed required for a single port of the standard communication rate for that modem. Basically, by utilizing a resource manager, that directs the data in and out of the various portions of the modem in an orderly manner, keeping track of which of the ports is being operated at any given point in time, a standard single port modem can be reconfigured, for example, at an over clocked rate, to manipulate the data input and output of a modem.
