    • A hardware device for processing the tasks of an algorithm of the type having a number of processes the execution of some of which depend on binary decisions has a plurality of task units (10, 12, 14), each of which are associated with a task defined as being either one process or one decision or one process together with a following decision. A task interconnection logic block (16) is connected to each task unit for communicating actions from a source task unit to a destination task unit. Each task unit includes a processor (18) for processing the steps of the associated task when a received action requests such a processing. A status manager (20) handles actions coming from other task units and builds actions to be sent to other task units.

    • A telecommunication node for an Asynchronous Transfer Mode (ATM) telecommunication network performs Segmentation and Reassembly (SAR) of ATM cells. The SAR particularly provides Virtual Channel Identifier (VCI) and Virtual Path Identifier (VPI) translation and further provides a Direct Memory Access (DMA) for accessing an external storage. When the VCI and VPI identifiers are representative of an Error Code Correcting (ECC) procedure to be carried out in the local mode, the SAR circuit performs a first DMA access which is decoded by an address decoder. Conversely, when no ECC procedure is locally required, the SAR decodes the VCI and VPI and performs a second DMA access which is also decoded by the address decoder. The latter decoding is then used by a Reed-Solomon Coder and Decoder for possibly performing an error correcting procedure on the ATM message formed by the ATM cells being processed.
    • 用于异步传输模式(ATM)电信网络的电信节点执行ATM信元的分段和重组(SAR)。 SAR特别提供虚拟信道标识符(VCI)和虚拟路径标识符(VPI)转换,并进一步提供用于访问外部存储器的直接存储器访问(DMA)。 当VCI和VPI标识符代表在本地模式下执行的错误代码校正(ECC)过程时,SAR电路执行由地址解码器解码的第一DMA访问。 相反,当本地不需要ECC过程时,SAR对VCI和VPI进行解码,并执行也被地址解码器解码的第二DMA访问。 后来的解码然后由Reed-Solomon编码器和解码器用于可能对正被处理的ATM信元形成的ATM信息执行纠错过程。

    • Method of reinitializing dictionaries in a data transmission system using data compression having a transmit device and a receive device, and in which strings of characters have to be transmitted in a compressed form, the transmit device having a transmit dictionary storing codewords associated with the strings of characters which are transmitted instead of the strings of characters, the receive device having a receive dictionary storing codewords associated with the strings of characters, and both dictionaries being updated each time a new string of characters has to be transmitted so that the contents of the dictionaries remain identical. This method saves at least the addresses of the parts of the transmit or receive dictionary which have to be modified by a dictionary updating operation, builds a check message based upon the contents of the transmit dictionary updated by the dictionary updating operation, transmits the check message from the transmit device to the receive device, and then deletes in both dictionaries the parts which are determined by the saved addresses in the event that the check message does not correspond to the contents of the updated receive dictionary. This enables both dictionaries to be reinitialized in an intermediate state without being reset.

    • An apparatus and a method to synchronize the clock signal of a first (or slave) data terminal equipment A (240-1) to a second (or master) data terminal equipment B (240-2) connected to a communication network (10) through respectively a first network node (51) and a second network node (52). The communication network has a reference clock that it transmits to the second network node which compares it with the clock signal that it receives from the second data terminal equipment. The phase difference is then detected and converted into a frame which may be an ATM cell or any other frames so that it can be switched with the data frames sent by the second DTE and transmitted to the first DTE through the communication network. The frame containing the phase difference has a specific header so that it can be distinguished from the other transmitted data frames. The first network node receives the frames, detects the phase difference frame and decodes it before it is sent to a digital to analog converter. This later generates then an analog signal which adjusts the phase of the reference clock that the first network node has extracted from the communication network. The adjusted clock signal is transmitted to the first DTE which is therefore synchronized with the second (or master) DTE.
    • 将第一(或从属)数据终端设备A(240-1)的时钟信号与连接到通信网络(10)的第二(或主))数据终端设备B(240-2)同步的装置和方法, 分别通过第一网络节点(51)和第二网络节点(52)。 通信网络具有它向第二网络节点发送的参考时钟,该第二网络节点与从第二数据终端设备接收的时钟信号进行比较。 然后检测相位差并将其转换成可以是ATM信元或任何其他帧的帧,使得其可以与由第二DTE发送的数据帧进行切换,并通过通信网络发送到第一DTE。 包含相位差的帧具有特定头部,使得其可以与其他发送的数据帧区分开。 第一网络节点接收帧,检测相位差帧并将其解码,然后发送到数模转换器。 这随后产生一个模拟信号,该模拟信号调节第一网络节点从通信网络提取的参考时钟的相位。 经调整的时钟信号被发送到第一DTE,因此第一DTE与第二(或主)DTE同步。
