A communication system provides PSTN access to a user device coupled to a packet network over a packet connection. The user device exchanges telephony signaling and telephony communications in an analog format with an analog telephone, exchanges the telephony signaling and the telephony communications in the packet format over the packet connection, and exchanges Internet communications over the packet connection. A service node exchanges the telephony signaling in the packet format with the user device, processes the telephony signaling to select a PSTN connection, transfers a control message indicating the PSTN connection, and exchanges the telephony signaling in a PSTN format with the PSTN. An interworking unit receives the control message, and in response, exchanges the telephony communications in the packet format with the user device and exchanges the telephony communications in the PSTN format with the selected PSTN connection.

Telecommunications system to provide analog telephony communications over a packet connection

The invention is a residential communication hub for a communication system that provides communications services to an end-user. The residential hub is connected to the communications system over a DSL connection. The residential hub converts voice traffic to ATM for transmission over the DSL connection. The communications system includes broadband networks and a service node to facilitate communications services for the end-user.

User communication hub for use with an analog phone line

The invention is a communications system that provides communications services to an end-user. The system includes a residential hub that is connected to the communications system over a DSL connection. The residential hub converts voice traffic to ATM for transmission over the DSL connection. The communications system includes an asynchronous communication system that is connected to a POTS system. The asynchronous communication system converts the ATM transmission to a PSTN format and transfers the PSTN format to the POTS system.

Telecommunications system

Methods for determining at least two pre-computed paths to a destination in a communications network are provided. The two paths are maximally disjoint. Maximally disjoint paths are paths where the number of links or nodes common to the two paths is minimized. This minimization is given a priority over other path considerations, such as bandwidth or cost metrics. By pre-computing a maximally disjoint pair of paths, the probability that an inoperable link or node is in both paths is minimized. The probability that the inoperable link or node blocks a transfer of data is minimized. Additionally, a pair of maximally disjoint paths is determined even if absolutely disjoint paths are not possible. The communications network may include at least four nodes, and maximally disjoint pairs of paths are pre-computed from each node to each other node. A third path from each node to each other node may also be computed as a function of bandwidth or a cost metric. Therefore, the advantages of the maximally disjoint pair of paths are provided as discussed above and a path associated with a higher bandwidth or lower cost is provided to more likely satisfy the user requirements of a data transfer.

Communications network system and method for routing based on disjoint pairs of path

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.

Asynchronous transfer mode architecture migration

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.

An ATM reference traffic system records packet information representative of ATM packets transmitted over an ATM network. The system also creates and transmits ATM packets from packet information on a schedule representative of ATM packet transmission over an ATM network. The preferred system uses a personal computer with the operating system modified to schedule events with microsecond resolution while providing interrupts to the operating system on a periodic basis.

A horse mask or halter manufactured by folding a single piece of screen material according to a pattern that ensures the formation of rigid darts in the portion of the mask corresponding to the eyes of the horse. The mask incorporates poll-protection padding that minimizes the risk of injury to the head of the horse during transportation in a horse trailer. A separate opening in the mask is provided for each ear to create an anchoring support that prevents the mask from shifting position over the head of the horse. Sheep skin is used to pad the edges of the mask and prevent the intrusion of insects.
