摘要:
The invention is an ATM communications system that provides the option of advanced communications services or conventional telephone service to the customer. Advantageously, the ATM communications system does not require the widespread deployment of class 5 telephone switches to provide telephone service. A residential communications hub is located at a residence and communicates with the telephones at the residence using the analog telephony format. The residential communications hub converts between the analog telephony format and the ATM format. The residential communications hub is connected to a DSL mux by telephone wiring that carries the ATM/DSL format. The residential communications hub and the DSL mux communicate using the ATM/DSL format. The DSL mux converts between the ATM/DSL format and the ATM/SONET format. The DSL mux is connected to the an ATM switch by a broadband connection that carries the ATM/SONET format. The DSL mux and the ATM switch communicate using the ATM/SONET format. The ATM switch establishes ATM communications paths for the telephone service. A telephony hub is connected to telephones by telephone wiring that carries the analog telephony format. The telephony hub communicates with the telephones using the analog telephony format. The telephony hub is connected to the ATM switch by a broadband connection that carries the ATM/SONET format. The telephony hub and the ATM switch communicate using the ATM/SONET format.

A method of operating a control database for a wireless communication system comprises receiving geographic coordinates for a wireless access hub and an identity of a wireless collector hub, retrieving geographic coordinates for the wireless collector hub, identifying a frequency band for wireless communication signals between a core communication network and the wireless collector hub, and identifying reserved time slots in the frequency band. The method also comprises selecting available time slots, processing the geographic coordinates to determine an azimuth and an angle for the wireless access and collector hubs to optimize signal strength, determining a power for the wireless communications signals between the wireless collector and access hubs, receiving a query for the wireless access and collector hubs, and transferring a response indicating the azimuth, the angle, the frequency band, the available time slots, and the power.

A repeater system is supplied for providing wireless communications. In an example, a repeater system is supplied to receive user information with an antenna in a wireless signal at a first frequency and transfer the user information in an electrical signal at the first frequency. A frequency converter receives the user information in the electrical signal at the first frequency and transfers the user information in the electrical signal at a second frequency. A first coupler receives the user information in the electrical signal at the second frequency and transfers the user information in a capacitive signal. A second coupler receives the user information in the capacitive signal and transfers the user information in an electrical signal at the second frequency. A second frequency converter receives the user information in the electrical signal at the second frequency and transfers the user information in the electrical signal at the first frequency. An antenna receives the user information in the electrical signal at the first frequency and transfers the user information in a wireless signal at the first frequency. Additionally, a method of providing wireless communications using the above mentioned repeater system is also provided.

The invention comprises a series of architectures that are implemented in four phases to provide a migration path from an initial ATM service offering to a full service ATM network. The initial ATM network includes several metropolitan ATM networks that are interconnected by a core ATM network. Each metropolitan ATM network includes a service node that controls ATM network elements to deliver services. In Phase I, a business hub that is connected to the metropolitan ATM network integrates voice, data, and Internet traffic over a single ATM connection that contains permanent Virtual Connections (PVCs) to various destinations, such as other business hubs, a gateway to local and long distance networks, the Internet, a frame relay network. In Phase II, the architecture is extended to smaller business markets. Businesses are provided with the PVC-based ATM service using xDSL/ATM connections that are multiplexed at a central office and then provided to the service node over the metropolitan ATM network. A remote dial-in feature is also added. In Phase III, a work-at-home hub is provided for telecommuting. The work-at-home hub uses an xDSL/ATM connection through the central office to the service node. Phase III also includes the deployment of a session manager and provider agents that interact to interpret user requests and establish the requisite communications paths using Switched Virtual Connections (SVCs). The business can replace existing some or all PVC-based service with more efficient SVC-based service. In Phase IV, the architecture is extended to the residential market. A residential hub is provided for residential communications over an xDSL/ATM connection through the central office to the service node. An analog hub is provided for conventional telephone service through the service node.

A water containment device and levee for impeding a flow of water. The water containment device includes a body portion having a first end, a second end, a base, and a first side and a second side attached to the base. At least one valve is disposed in the first end for introducing a water into the body portion. A flap is also provided that is integrally formed with the body portion and extends outward therefrom. The flap for receiving another water containment device thereon and impeding movement of the water containment device. The flap is also used to divert the flow of water away from the levee should the level of the water exceed the levee.

A programmable telephone line device (10) for selectively interconnecting two or more telephone lines between a plurality of communication instruments is disclosed. The device (10) includes an assignment matrix (24) for inter-connecting the telephone lines with the communication instruments and a control assembly (26) for automatically or manually directing the assignment matrix (24) to transfer a communication instrument from its primary telephone line to a roll-over telephone line if its primary telephone line is in use.

A system and method for interconnecting multiple mesh transport medium technologies is disclosed. Two nodes are part of a mesh sub-network using a first access technology. The two nodes have at least two paths using the first access technology that couple the two nodes together. A third path using a second access technology also couples the two nodes together.

A gyroscope monitoring system operates with an antenna system that has a gyroscope that controls the position of multiple antennas. The monitoring system receives data indicating reference signal strengths and test signal strengths for the antennas. The monitoring system determines differences between the reference signal strengths and the test signal strengths. The monitoring system processes the differences to determine if the gyroscope has lost reference point accuracy, and if so, then the monitoring system generates an indication that the gyroscope has lost reference point accuracy. In some examples, the monitoring system also determines reference point offsets for the gyroscope and provides the offsets to the gyroscope for use in motion measurements.
