Filed:

Nov 16, 2000

Appl. No.:

09/714771

Inventors:

John C. Goluch - Aurora IL
Christopher F. Simanonis - Winfield IL
George G. Wagner - Naperville IL
Mark S. Ziermann - Bolingbrook IL

Assignee:

Westell Technologies, Inc. - Aurora IL

International Classification:

H04B 304

US Classification:

333 20, 379347, 37941302

Abstract:

An improved, more intelligent network interface unit capable of processing signals received from a high speed transmission media and outputting the received signals without substantial amplification or reduction. The network interface unit comprises a regenerator circuit which detects T1 signals from said high-speed transmission media and outputs a digital stream to a serial data processor for processing via a micro-controller. A wave shaper circuit receives the output from the serial data processor and, in conjunction with the micro-controller and a level detector circuit, regenerates signals having substantially the same wave shape and amplitude as the original T1 signals received from said transmission media.

US Classification:

398 33, 398 45, 398 55, 398 82

Abstract:

A system and method are presented for demarcating an optical network. The system comprises an optical monitor that receives a portion of an outbound signal from an optical network and generates a switch control signal based on the intensity of the outbound signal. Generally, the switch control signal is active when the intensity of the outbound signal falls below a threshold value. Alternatively, the system comprises an override switch, and the switch control signal is active when the override signal is activated or the outbound signal falls below a threshold value. An optical switch receives the switch control signal, and selectively isolates the network generating the outbound signal from the rest of the network when the switch control signal is active. The method for demarcating an optical network comprises generally coupling both the inbound signals of first and second networks and the outbound signals of the networks, and selectively isolating the first and second networks by looping signals back into the networks when the outbound signal of the second network falls below a threshold value.

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.

Appl. No.:

11/936529

Inventors:

Christopher F. Simanonis - Winfield IL, US

Assignee:

WESTELL TECHNOLOGIES, INC. - Aurora IL

International Classification:

G06F 13/12

US Classification:

710 10

Abstract:

An apparatus and method are disclosed for optimizing use of a modem jack. For a computer system that includes a modem, an apparatus may include a first branch including a first end that is arranged to connect to an Ethernet jack of the modem, a second branch including a second end that is arranged to connect to an Ethernet interface of the computer system, and a third branch including a third end that is arranged to connect to a USB interface of the computer system. The Ethernet jack of the modem will then receive both Ethernet and USB signals.

US Classification:

370 13

Abstract:

A full duplex digital transmission, high-capacity digital, facility loop-back test, diagnostics and maintenance system having a digital transmission facility, transmission medium, and at least one microprocessor-based, full duplex facility loop-back diagnostics interface is located at predetermined end-user locations within the system. The system is capable of initiating a facility loop-back test and predetermined diagnostics for a predetermined digital transmission span and customer premises equipment at the location of the network interface for a specified end-user. The facility loop-back diagnostics interface has a performance monitoring mode of operation and a maintenance facility loop-back mode of operation. The diagnostics interface can be activated from a remote location and is compatible with and supports a particular protocol, specifically LAP-B protocol. The diagnostics interface has integral performance monitoring capabilities for nonintrusive multiple diagnostics testing and on-line monitoring of multiple predetermined performance characteristics for associated DS1 communications channels, or a specified DS1 communications channel, and customer premises equipment at the network interface.
