Abstract: Systems and methods for fusing, for a subscriber, a plurality of applications and subscriber data across a plurality of subscriber access devices are described. The system includes a fusion server coupled to a voice-over-IP telephony switch and a television EBIF server. The fusion server receives and stores the subscriber data such as a list of contacts. The fusion server receives a communication in a first format from a first subscriber access device such as a set-top box, and translates the communication from the first format to a second format. The first and second formats include at least two of session initiation protocol (SIP), hypertext transfer protocol (HTTP), voice-over-IP (VoIP), simple object access protocol over extensible markup language (SOAP/XML), remote procedure call (RPC), and enhanced tv binary exchange format (EBIF). The fusion server transmits the translated communication to a second subscriber access device such as a smart phone or tablet computer.

Abstract: Disclosed is a method and apparatus for improving LAN availability and robustness employing adjacency status self-discovery on segment-to-segment communications paths. In some embodiments, the method and system may employ Logical Link Control Type 1 test frame messages between segment nodes to determine status. Adjacent node status may be determined by waiting a period of time for an acknowledgment message and marking the tested link as “down” if no response is received. Also disclosed is a method for compacting data transmitted over a network to reduce overhead.

Abstract: Presently described is a system and method for switching multimedia data communications, including but not limited to Voice over IP (VoIP) telephony, cable TV, digital audio and video. The system utilizes a single, integrated device to provide all PacketCable-compliant functionality, including enhanced user privacy, compliance with CALEA, E911 and other mandated services not available in conventional distributed PacketCable systems. High speed and efficient, low cost operation are provided by means of an optimized data unit encapsulation scheme for internal switching and routing. A proprietary fiber optic backplane and removable optical connectors are used to enable lightspeed internal communications hot-swapping of components. Furthermore, the present system is extensible to all forms of digital data switching and is secure, resistant to Denial of Service attacks, and fault-resilient.

Abstract: The invention includes, among other things, a system for passing TDM traffic through a packet switch. In one embodiment, the system includes a packet switch that has a plurality of data ports and is capable of routing FSDU packets between the plurality of data ports. A TDM encapsulation circuit process a TDM data flow that is incoming to the switch. A circuit demultiplexer processes the incoming data flow to buffer data associated with different TDM circuits into different buffer locations. A timer monitors the amount of time available to fill the FSDU, and when the time period reaches the frame boundary, an FSDU generator generates an FSDU that is filled with data associated with the TDM circuits. Header information is added for allowing the packet switch to route the generated FSDU to a port associated with the respective TDM circuit.

Abstract: The master/slave arbitration process includes a voting process that allows cards within the system to use voting to determine the health of each of the individual cards. The voting process thereby allows the system to determine whether a bad card is present and to make sure that a bad card has not been selected to be the master card for the system. By preventing a bad or malfunctioning card from being selected as the master, the systems and methods described herein guard against a system failure that may arise from appointing a malfunctioning card as the master card.

Abstract: Systems for in-band control that establish relationships between incoming data and one or more destinations to which the data is to be transmitted. In the in-band control embodiments described herein, a connection is established between two ends of a circuit by provisioning at one end of the circuit. A circuit connection table is kept at both ends of the circuit. This table contains the new and existing circuit connection information. A software process writes to the connection table at the local end of the circuit with the address information of the remote end of the circuit. The circuit connection information is to be periodically sent to the remote end to establish or tear down new connections.

Abstract: Telecommunications switches for connecting circuits across a network and having an emergency notification system that allows access to customer premise equipment, such as a telephone, mobile telephone, VOIP telephone, or any other type of customer premise equipment, and delivers to that CPE an alarm or another message. The telecommunication switch may include a dial plan server that will allow a security officer or other user to develop a dialing plan that controls telecommunication switch such that identification numbers, typically telephone numbers, can be dialed by the switch to call CPE throughout the telecommunication network. Additionally, the dialing plan allows the security officer to divide and organize an institution into different sectors, and these different sectors may be delivered different messages. The sectors may be geographic, they may be organized based on the classification of individuals within the institution, or they may be based on some other characteristic.

Abstract: The present invention is directed to a reconfigurable data communications system. The system includes a removable optical backplane connector with a first end and a second end, a first data communications card, and a switch fabric card. The first data communications card includes an optical port configured to receive the first end of the removable optical backplane connector. The switch fabric card has a plurality of optical ports adapted to receive the second end of the removable optical backplane connector.

Abstract: The present invention is directed to a system and method for actively auditing a software system to determine the status. The software system includes a plurality of processes executed in an active processor domain. An active message is generated for processing in the active processor domain. Each process receiving the message modifies it by adding an active time indicator to it; thereby creating a modified active message. The status of the active processor domain is determined in response to the modified active message.
