Abstract: A desynchonizer for a synchronous digital communications system serves to recover a useful signal from a synchronous digital input signal. It comprises a buffer for temporarily storing the input signal, a write circuit for writing the input signal into the buffer, a clock-generating circuit for generating a clock signal, and a read circuit for reading the contents of the buffer at the recovered clock rate. According to the invention, the clock-generating circuit includes a calculating circuit for determining an average over the interval between two pointer actions of the input signal, and derives from the average a tuning signal which serves to adjust the recovered clock signal. In this manner, jitter caused by pointer actions which result from a constant offset of the effective bit rate of the received virtual containers is eliminated.

Abstract: A compiler for compiling source code whereby the compiled source code is optimized by performing outer loop unrolling (a generalization of “unroll and jam” on selected loop nests. The present invention allows any arbitrarily deep loop nests with non-varying loop bounds to be properly unrolled even in the presence of imperfectly nested code. This is accomplished for two-deep loop nests by transforming the code into multiple adjacent loop nests. In the transformed code, the imperfect code is isolated so that one of the adjacent loops nests has none, and thus can be unrolled and jammed. For three-deep or greater loop nests, the process is repeated recursively from the outer-most loop. The present invention also allows outer loop unrolling for two-deep loop nests with convex bounds, even with the presence of imperfectly nested code. This is accomplished by identifying strips of code which do not contain imperfectly nested code. An unroll and jam operation is executed for the identified strips.

Abstract: A process (100) for forming a metal interconnect (102) in a semiconductor device (82) using a photoresist layer (20) having a thickness (T) of no more than 0.66 microns without forming a notch in the side (30) of the interconnect. A reactive ion etching process (118) used to remove portions of a metal layer (16) to form the interconnect includes a burst etch step (108) wherein a first high flow rate (48) of passivation gas is delivered, followed by a main metal etch step (110) wherein the flow rate of passivation gas is reduced to a second lower value.

Abstract: A synchronization device for a synchronous digital message transmission system producing a synchronous output signal including successive transport modules synchronized to a frame clock from a digital input signal. The synchronization device includes a receiver unit for receiving the input signal, a packet assembly device for packaging the input signal into subassemblies of the transport modules, a buffer memory, a writer for writing data bits of the input signal out of the subassemblies into the buffer memory with a write clock, a reader, for reading data bits out of the buffer memory with a read clock in order to form the output signal, and a sending unit (SO) for sending synchronous output signals. The effective bit rate of the subassemblies compared to the standardized value is either lowered or raised by selecting the write clock lower than the read clock.

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.
