    摘要: The invention relates to multilevel interrupt device (10) using a common microprocessor interrupt signal (101) to process interrupt signals (INT1, . . . , INTN) received from N peripheral chips. This device (10) is connected to a microprocessor (100) and N peripheral chips (200,210,230) through data/address busses (108,110) and it is also connected to a memory (150) by an additional bus (112). An interrupt operation starts when any one of the peripheral chips activates an interrupt signal through OR gate (220) detected by the microprocessor. The invention avoids to involve the microprocessor in the determination of the interrupt requester except for the generation of a common start.sub.-- address decoded by logic (180) for starting interrupt operations and a common end.sub.-- address decoded by logic (190) for ending it. Owing to the start.sub.-- address and the interrupt signals (173,174) received, latch (170) generates a translated address to memory (150) through a multiplexer (160) to start the corresponding interrupt routine stored at this translated address. The activation of any one of the peripheral chips leads to the reading of the corresponding interrupt routine stored in the memory without requiring any action of the microprocessor. The number of interrupt routines depends on the possible combinations of the N interrupt signals.

    摘要: The invention provides an impedance adapter that automaticaly switches to impedances that match network transmit/receive lines impedances (105,106) by a controlled switching of various impedances mounted serially/parallely with connected transmitter/receiver (100,101). For a high speed adapter, a balanced transmitter/receiver is required for limiting crosstalk effect due to the high transmission rate. Transmit/Receive impedance adaptation networks (102-103) are composed of serial/parallel networks of resistors and relay contacts that are switched independently by magnetic coils of an impedance switching circuit (110) and having values conformable to the various network impedances imposed by different national regulations. By using the principle of double deviation voltage technique, a measuring circuit (108) detects upward and downward voltages (VA,VB), VB amplified by 2 to generate an analog signal VS (VS=VA-2VB) to a control logic circuit (109). This circuit (109) determines if the resistors value selected by the magnetic coils of said impedance switching circuit (110) is equal or not equal to the impedance of the network lines (106,105). Thus, it compares VS to a voltage Vref (25) to generate an output which selects and activates the correct magnetic coil for changing or keeping equal the resistors of the receive/transmit impedance network (102,103) currently connected to the network lines (105,106).

    摘要: A method and system for implementing secure network communications between a first device and a second device, at least one of the devices communicating with the other device via a firewall device, are provided. The method and system may include obtaining an encryption parameter that is shared by the first device, second device and firewall device. A data packet sent by the first device may then be copied within the firewall device, so that decryption of the copy of the data packet within a portion of the firewall device may take place. In particular, the portion of the firewall device in which decryption takes place is defined such that contents of the portion are inaccessible to an operator of the firewall device. Thus, scanning of the decrypted copy of the data packet for compliance with a predetermined criterion may take place within the firewall device, without an operator of the firewall device having access to the contents of the data packet to be transmitted. Thereafter, the original data packet can be forwarded to its originally intended recipient.

    摘要: A method and system for reserving a virtual connection from a source workstation to a destination workstation. Packets of data are transmitted over a network between an ingress node of the source workstation and an egress node of the destination workstation. In accordance with the method of the present invention, a reservation request is delivered from the source workstation to a reservation server. The reservation server includes a user database for storing the identification of each user allowed to access to the reservation server and also stores the rights of each user. The reservation server further includes a network database for storing the information describing a network capacity required to set up the virtual connection. A verification is then performed to determine whether or not the reservation request may be validated in view of user information within said source workstation. A second verification is performed to determine whether or not the capacity of said network is sufficient to meet the requirements of the reservation request. In response to the capacity of the network being sufficient to meet the requirements of the reservation request, a virtual connection is established from the ingress node to the egress node.

    摘要: A node for a telecommunications network has a segmentation and reassembly module (SAR module) to perform segmentation and reassembly (SAR) on cells received by the node, the SAR module particularly providing Virtual Channel Identifier (VCI) and Virtual Path Identifier (VPI) translation (referred to as VCI/VPI translation), and has a direct memory access (DMA) mechanism for a storage external to the SAR module, the SAR module performing a first DMA access when the VCI/VPI translation are representative of an error code correcting (ECC) procedure to be carried out in the node, and the SAR module performing a second DMA access when the VCI/VPI translation corresponds to a message that does not require a local ECC procedure. A coder/decoder module performs an ECC procedure on the cells. A controller controls the coder/decoder module to perform an error correcting procedure in response to the detection of the first DMA access. The first DMA access uses a first address and the second DMA uses a second address. A Reed-Solomon coder-decoder or a Hamming coder-decoder may be used to perform the ECC procedure. An address decoder interprets the VCI/VPI identifiers to control whether or not an ECC procedure is done.
