摘要:
A lightweight active phased array antenna including modular active electronics assemblies and passive radiating element aperture panels that are integrated into a lightweight support structure of a minimum depth which provides a cooling system for the electronics assemblies. The electronics assemblies and aperture panels are fully accessible from one or both faces of the antenna and can be readily removed/replaced as required.

An Internet server is operatively coupled to a configurable set-top terminal (STT), thereby providing remote access to the configurable STT through the Internet server. The Internet server is configured to provide web-pages that preferably emulate the user interface for the configurable STT. In that regard, a subscriber can log into the Internet server and configure the configurable STT from various devices that are Internet-compatible. The Internet server is configured to translate input by the subscriber into configuration information for the configurable STT that is pushed out to the configurable STT directly after being received from the subscriber.

Disclosed is an apparatus and method for switching between two network lines, such as telephone subscriber lines. Households and offices are increasingly equipped with multiple network lines for voice and data communications. The line switching unit of the present invention has a first terminal for receiving a CPE line from a CPE device. First and second switches of the unit each connect a common terminal to a first switched terminal responsive to a first value of a control signal received at a control terminal of each switch and to a second switched terminal responsive to a second value of the control signal. The first switched terminal of the first switch is connected to the first terminal and the second switched terminal of the second switch is connected to the first terminal. The common terminal of the first switch is connected to a first network line and the common terminal of the second switch is connected to a second network line. A further aspect of the present invention includes a control unit that senses an off-hook signal on the CPE line and, when the control signal is in a state of outputting the first value, checks a state of the first network line to determine if it is in use. If the first network line is in use, then the control unit checks a state of the second network line. If the second network line is not in use, then the control unit changes the state of the control signal to output the second value of the control signal.

Disclosed is an architecture and method for high speed transmission over a four-wire subscriber line. Each modem in the present invention includes a V.90 transmit section and a V.90 receive section. The V.90 transmit section is dedicated to transmitting data over one pair of a four-wire subscriber line, while the V.90 receive section is dedicated to receiving data over the other pair of the four-wire subscriber line. The present invention permits full-duplex transmission at 56 Kbps over a four-wire subscriber line.
