Abstract: The present invention relates to a process for establishing point-to-multipoint connections (A14, A33, A34) and multipoint-to-point connections (B14, B15, B35) in a coupling field comprised of a number of stages (I, II, III), each with a number of switching modules (11-15, 21-25, 31-35). To that end, when there are switching modules (21-25) in at least one stage (II), and if, depending on their type, these switching modules are capable of simultaneously splitting point-to-multipoint connections (A14, A33, A34) and of coupling together multipoint-to-point connections (B14, B15, B35), the proposition is made to connect point-to-multipoint connections (A14, A33, A34) in switching modules (25) in which more inputs than outputs are already loaded with connections and to connect multipoint-to-point connections (B14, B15, B35) by switching modules (24) in which more outputs than inputs are already loaded with connections.

Abstract: The network elements NE1, . . . , NE6 of a synchronous digital communications system must be synchronized with each other without the possibility of clock loops occurring. A network node NODE contains network elements NE1, . . . , NE6 and a central clock generator SASE. The network elements transmit clock signals 2M to the clock generator, which contain a clock of a message signal STM-N and a quality indicator (SSM) contained in the message signal which reflects the accuracy of the clock. The clock generator selects one of the clock signals 2M as the reference clock REF and informs the control installation STE which of the clock signals it has selected and the degree of accuracy of this clock signal. On the basis of this message STAT the control installation gives instructions ANW to the network elements with respect to the quality indicator which the network elements are to transmit to their outputs.

Abstract: Network terminations are made available to a customer and installed by a network operator of a digital communications network. The customer is responsible for the supply of power to the network terminations. In the event of a power failure, a network termination of the digital communications network sends an error message (FM) to the customer who is responsible for correcting the power failure. The error message (FM) is sent in the payload of the digital message signals. The network termination (NT) includes a power supply (USV) which in the event of the power failure can sustain output for a predetermined period of time, in which the error can be signaled. To signal the error, the payload may be overwritten with a predetermined bit pattern (BM).

Abstract: The synchronous digital communications system according to the invention serves to transmit electric signals optically. The electric signals to be transmitted are converted from electrical to optical form (E/O1, E/O2, E/On) and are transmitted using wavelength division multiplexing (WDM) or dense wavelength division multiplexing (DWDM). At least one optical connection is configured as a nonswitched connection using at least one wavelength per transmission section between optical network elements or optical and electrical network elements, and serves to transmit synchronization and information signals. This has the advantage that independently of the switched communication links, synchronization is constantly ensured throughout the network. Each network element (NE1, NE2, NE3) has at least one interface unit that is reserved for synchronization and that continuously receives signals at the wavelength (&lgr;1) reserved for synchronization.

Abstract: The digital file management system and method of the present invention provides a processing service that may be located remotely on a computer network that receives digital files from users and performs file identification, authentication and verification, including time and digital signature. The system and method may include the remote processing and storage of file information such that the user does not need to maintain any application specific software at the user's local site. The system and method may record additional independent data with each stored file including: a “true date” gleaned from a secure clock which is not settable by the user (the Authentidate™); a number derived from a cyclic redundancy code (CRC) algorithm or checksum routine against the file; and a CRC or checksum derived from the “true date”, (the “date CRC”). This additional data may be recorded within each digital file after the file is acquired.

Abstract: An automatic door answering system comprises a door intercom system, a recording machine, a telecommunication system, first, second and third interfaces, and a microprocessor-based switching device. The switching device is coupled to the door intercom system, the recording machine, and the telecommunication system by way of the first, second, and third interfaces, respectively. The switching device switches back and forth between coupling the door intercom system to a telecommunication system, coupling the door intercom system to a recording machine, and coupling the telecommunication system to the recording machine. If the recipient of a visitor is not available, the automatic door answering system establishes a communication link between the visitor and the recipient using the door intercom system and the telecommunication system. If the recipient of the visitor is not available, the automatic door answering system allows the visitor to record a message for the recipient.

Abstract: In a computer system, a method for determining an optimal loop interchange, set of register tiling amount, and cache tiling size for compiling source code into object code. The method first constructs a model of the specific computer system upon which the object code is to be run. Next, the search space comprising all of the different possibilities of the loop interchanges, register tiling amounts, and cache tiling sizes is run through the model to determine estimated times of execution. The particular loop interchange, set of register tiling amounts, and cache tiling sizes corresponding to the best estimated time of execution is then selected as being the most optimal. The source code is then compiled according to this optimal loop interchange, register tiling amount, and cache tiling size.

Abstract: A transmission system is indicated for digital signals combined into a multiplex signal, and a network element for such a transmission system. Each network element contains an adapter circuit to balance phase variations in an incoming multiplex signal. The adapter circuit has a buffer memory (1) for payload data bytes, a write address generator (2) which controls the buffer memory (1) in a way so that a number of payload data bytes is stored within one write cycle, and has a read address generator (3) which controls the buffer memory (1) in a way so that the number of payload data bytes stored within the write cycle is greater than the number of payload data bytes read during the read cycle. Each network element has a sort facility (5) which sorts the read payload data bytes, so that a multiplex signal that is transmitted by a network element has the established frame format.

Abstract: Network elements of a synchronous digital communications system have a clock generator for generating a clock signal locked to an input signal. Such a clock generator comprises a tunable oscillator (OSC) and a phase comparator (PK) for comparing the phase of the input signal (IN) with the phase of the clock signal (CLK) and for generating a correction signal which serves to tune the oscillator (OSC). To avoid phase transients due to interruptions and disturbances in the input signal (IN), means (WD) are provided for determining an expectancy window, for deciding whether the correction signal lies within the expectancy window, and for tuning the oscillator with the correction signal if the correction signal lies within the expectancy window.

Abstract: A device for automatically closing a closure installation (such as a window or a door) includes a drive device, a traction mechanism, a spring, an actuating device and a locking device. The closure installation is mounted in a frame supported by a building. The traction mechanism is located between the closure installation and the frame, and is driven by the drive device to close the closure installation. The spring is tensioned when the closure installation is placed in the open position, and supplies the energy to the drive device which is required to close the closure installation. The actuating device is used to initially place the closure installation in the open position. The actuating device tensions the spring when the closure installation is placed in the open position. The locking device is initially released to permit the closure installation to be placed in the open position.

Abstract: An apparatus, to be used in a desynchronizer, for minimizing the output jitter of the desynchronizer. The desynchronizer is assumed to include a bit buffer for staging data that is to be output. The desynchronizer is also assumed to include a means for decoding the input signal to determine how justification opportunities in the input signal are used and therefore what justification bits must be leaked by the desynchronizer. The apparatus and method of the present invention uses the information about the incoming justification bits or incoming justification bytes and the state of the buffer to determine the longest possible time to wait before issuing a command to momentarily speed up or delay outputting the next data unit from the bit buffer.
