Xdsl Multi-Hybrid Modem With Power Spectral Density Shaping

View page
US Patent:
7406117, Jul 29, 2008
Filed:
Mar 21, 2002
Appl. No.:
10/103478
Inventors:
Greg Bella - Naperville IL,
Henry Gilsdorf - Earlville IL,
George Pitsoulakis - Orland Park IL,
Assignee:
Westell Technologies, Inc. - Aurora IL
International Classification:
H04B 1/38
H04L 5/16
H04B 3/00
US Classification:
375219, 375296
Abstract:
Power spectral density shaping can be used in an XDSL system in order to adjust power spectral density properties of signals transmitted by an XDSL modem. The XDSL modem may include a power spectral density shaping filter, which can be adjusted to change the power spectral density properties of outputted signals. A processor may also perform power spectral density shaping of signals transmitted by the XDSL modem. The power spectral density shaping may be used to increase a downstream transmission rate.

System And Method For Tearing Down Individual Ip Communication Sessions In Multiple Ip Stack Devices

View page
US Patent:
8112532, Feb 7, 2012
Filed:
Jun 23, 2009
Appl. No.:
12/490079
Inventors:
Mankesh S. Ahluwalia - Schaumburg IL,
Narothum Saxena - Hoffman Estates IL,
Michael Irizarry - Algonquin IL,
George Pitsoulakis - Orland Park IL,
Assignee:
United States Cellular Corporation - Chicago IL
International Classification:
G06F 15/16
US Classification:
709227, 709228
Abstract:
Embodiments of the invention are used to provide a system and method for tearing down and reclaiming an IP address from a multi-IP stack device based on configurable timer parameters that provide a network operator with independent control over each protocol-specific IP network layer session. Dedicated idle and session timers for each IP network layer session are implemented at the network layer of various network nodes in order to independently tear down IPv4 and IPv6 network sessions while maintaining the underlying link layer connection. In embodiments, the IP protocol-specific idle and session timers are processed by the Packet Data Serving Node (PDSN) or the Home Agent (HA). To achieve user session level control of IP protocol-specific network layer sessions, embodiments of the invention provide for storing the network layer idle and session timer attributes at the Authentication, Authorization and Accounting (AAA) server prior to passing such attributes to the PDSN or the HA for processing during the dual-stack communication session.

Modem Having Flexible Architecture For Connecting To Multiple Channel Interfaces

US Patent:
2003003, Feb 20, 2003
Filed:
Jul 12, 2002
Appl. No.:
10/181045
Inventors:
George Pitsoulakis - Orland Park IL,
International Classification:
H04B001/38
H04L005/16
US Classification:
375/222000, 375/220000, 375/219000
Abstract:
The present invention is directed to an integrated access device (IAD) that provides multiple communication interfaces for communications to a variety of service providers. The disclosed IAD acts as a DSL modem and combines the functions of a gateway, router, and Ethernet hub to provide high-speed Internet access to PCs sharing a local network. It provides the networking functions that let PCs connect through a variety of methods, including traditional Ethernet, wireless, universal serial bus (USB), and home phoneline networking alliance (HPNA). It also provides point-to-point protocol over Ethernet (PPPOE) tunneling through network address translation (NAT).

In-Home Voice-Over-Internet-Protocol Telephony Distribution

US Patent:
2006007, Apr 13, 2006
Filed:
Sep 30, 2005
Appl. No.:
11/241465
Inventors:
George Pitsoulakis - Orland Park IL,
Christopher Simanonis - Winfield IL,
Mark Ziermann - Bolingbrook IL,
Mark Beegle - Shorewood IL,
Assignee:
Westell Technologies, Inc. - Aurora IL
International Classification:
H04L 12/66
US Classification:
370352000
Abstract:
Several examples for in-home Voice-Over-Internet Protocol (VOIP) telephony distribution are described. In one example, an analog telephone adapter may be modified to provide wireless capabilities. In another example, an isolation device or circuit may be added to a Network Interface Device or a Central Office. In yet another example, a second pair of wires may be used to provide VOIP service. As a result of implementing any one of these examples, a user may place a VOIP call throughout the user's home without being tethered to a fixed location.
