Patent number: 7570706Abstract: A method of controlling a communication device that is operable to transmit digital data over a plurality of frequency channels. The method includes selecting an initial transmission power and a corresponding data rate for each channel. The method also includes identifying in a first channel a first ratio of a first decrement in transmission power to a first data rate decrement that is greater than a second ratio of a second decrement in transmission power to a second data rate decrement. Then, the initial transmission power allocation of the first channel is reduced by the first decrement. The method also includes reallocating the decremented initial transmission power of the first channel to one or more other channels.Type: GrantFiled: March 31, 2006Date of Patent: August 4, 2009Assignee: AT&T Intellectual Property II, LPInventors: Richard Henry Erving, Lalitha Sankaranarayanan

Patent number: 7263184Abstract: In a speakerphone device identification of signals (i.e., voice input or speaker output) in a process for reducing acoustic feedback, in a communication device, is accomplished by adding a signature noise (i.e., an identification mark) to output signals radiated by the speaker to enable these signals to be separated from speech input to the microphone. Having identified the signal (i.e., speech output) likely to cause a “singing” phenomenon, appropriate insertion loss to reduce the feedback may be added to the appropriate speech path within the communication device, to reduce a probability of singing.Type: GrantFiled: March 3, 2006Date of Patent: August 28, 2007Assignee: AT&T Corp.Inventors: Richard Henry Erving, Robert Raymond Miller, II

Patent number: 7164672Abstract: A method for improving packetized speech transmitted over a wireless LAN is disclosed. Speech packets transmitted over the wireless LAN are monitored for errors. Any of the speech packets found to have errors are replaced with synthesized speech packets. The synthesized speech packets may be created from a vocal tract model generated from the received speech packets during periods of time when there are no errors.Type: GrantFiled: March 29, 2002Date of Patent: January 16, 2007Assignee: AT&T Corp.Inventors: Richard Henry Erving, Robert Raymond Miller, II

Patent number: 7010002Abstract: The present invention sets forth a network-centric service distribution architecture and method that integrates a wireless access system/service in the residence, SOHO, business or public environment through the use of a local broadband network, such as a Residential-Business Broadband Network (RBN), to the service provider's broadband transport network and to a service provider's broadband packet network that facilitates end-to-end packet telecommunication services. Access functions for connecting said service provider's broadband packet network to the RBN via said service provider's broadband transport network are provided. Call and service termination functions to a plurality of local RBN devices are also provided. Signals from a plurality of wireless devices are accepted and forwarded to an IEEE 802.11b interface for a wireless modem and/or to an Ethernet interface for a Voice over Internet Protocol (VOIP)/Ethernet Processor, where the forwarded signals comprise intranet telephony and data.Type: GrantFiled: June 14, 2001Date of Patent: March 7, 2006Assignee: AT&T Corp.Inventors: Albert T.

The system includes a Media Terminal Adapter coupled via the RBN to the access port(s) and via the service provider's broadband transport network to the service provider's broadband packet network. The access port is coupled to the Media Terminal Adapter via either an RBN (e.g., a Local Area Network—LAN) or simply via a traditional POTS line interface. The access port receives and sends wireless signals to a plurality of RBN devices, allowing the user to control these devices remotely from the residence, business, SOHO or public environments.Type: GrantFiled: June 14, 2001Date of Patent: February 21, 2006Assignee: AT&T Corp.Inventors: Albert T.

Patent number: 6707886Abstract: A subscriber loop test apparatus relates to the testing of a subscriber loop by the use of a touchtone telephone. The touchstone buttons on a telephone provide Dual-Tone, Multiple Frequencies for each key pressed. For example, referring to FIG. 1, pressing the ‘3’ key causes tones at 697 and 1477 Hz to be sent across the telephone line. Pressing a sequence of keys provides discrete coverage of the frequency band from 697 to 1477 Hz, through the use of the touchtone telephone. The frequency band from 697 to 1477 Hz can be characterized in this fashion. Information about the line: loop loss (loop length), presence of bridge taps (i.e., excessively long bridge taps in particular) or loading coils, and the presence of Digital Loop Carriers (DLCs), et cetera. The use of the switch-hook flash provides the ability to determine the channel (impulse) response of the loop, including any noise and hum that may be on the loop due to imbalance or coupled interference.Type: GrantFiled: February 12, 2002Date of Patent: March 16, 2004Assignee: AT&T Corp.Inventors: Richard Henry Erving, Maura Elizabeth Marcus, Robert Raymond Miller, II, Christopher W.

Patent number: 6643504Abstract: Automatic activation (i.e., first time access) of digital wireless/cellular mobile telephones with a private/localized wireless/cellular system (i.e. a secondary system) occurs within an area having an overlapping macrocellular primary wireless communication system (i.e., a dominant system). Operation of the secondary access procedure is achieved by shielding/masking an access and authentication process for the secondary system from interference from the control signal levels of the dominant wireless communication system. During the first time access, the secondary system is supplied with the SID and MIN and ESN numbers for authentication and resultant access.Type: GrantFiled: July 10, 2000Date of Patent: November 4, 2003Assignee: AT&T Corp.Inventors: Albert T.

Patent number: 6580710Abstract: Broadband services are provided to customer premises, whose existing premise wiring does not have broadband capability, by disaggregating the various signals, including broadband services, supplied to the premise from a broadband communication link at the customer premise's edge, so that the existing POTS wires, within the customer premises, may function as separate channels for varied broadband and narrow band services. Intra premises broad band services are disaggregated so that POTS service responds normally to the network while internal LAN networks operate independently of the outside system network.Type: GrantFiled: November 19, 1999Date of Patent: June 17, 2003Assignee: AT&T Corp.Inventors: Donald John Bowen, Richard Henry Erving, Robert Raymond Miller, II, John F.
