Abstract: A telephony services provider arrangement is diclosed for use in connection with a server in a home area network, the telephony services provider arrangement being configured to provide at least one telephony service in connection with at least one telephony device connected to the server. The telephony services provider arrangement comprises a telephone interface and a control module. The telephone interface is configured to, in a telephone link connected state, connect the at least one telephony device to a telephone link and, in a telephone link disconnected state, disconnect the at least one telephony device from the telephone link to facilitate provision of the at least one telephony service to the at least one telephony device.

Abstract: A fault-tolerant computer system provides information transfers between the units of a computing module, including a processor unit and a memory unit and one or more peripheral control units, on a bus structure common to all the units. Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner. Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units. The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units.Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit.
