  • Patent number: 7023804
    Abstract: The method for the non-disruptive monitoring of a packet flow from a target point (e.g., a specific port/VPI/VCI) to a counterpart point in a packet switch having one or more interface devices, connected to an internal bus, for servicing the target point, the counterpart point and a monitor test access connection (TAC) point comprises the steps of: (a) configuring the device servicing the TAC point to retrieve from the bus packets addressed thereto which use a multicast addressing scheme for routing packets from the target point to the counterpart point and from the target point to the monitor TAC point; (b) configuring the device servicing the counterpart point to additionally retrieve the multicast packets from the bus; and (c) configuring the device servicing the target point to address packets received thereat to the counterpart point and the monitor TAC point using the multicast address scheme only after step (b) is completed.

  • Patent number: 7006447
    Abstract: Apparatus, and an associated method, provides for field-testing and calibration of a WLAN device. In testing of the receive portion of the WLAN device, test apparatus is provided with a transmit signal of known characteristics. The test apparatus selectably attenuates the transmit signal to form an attenuated signal. The WLAN device is connected to receive the transmit signal, once attenuated by the test apparatus. Responsive to differences between measured and calculated characteristics of the transmit signal, calibration for determination of proper operation of the WLAN device is made and calibration of the WLAN device is effectuated.

  • Patent number: 6963544
    Abstract: A system for providing statistical multiplexing of speech, other real-time data services and non-real-time data services for point to point and point to multipoint communications. The system has fast access and assignment procedures that allow the multiplexing of real-time, delay-critical data services with non-real-time data services. Continuity of periodic control channels across speech talkspurt and silence periods for conversational voice is maintained to carry signal measurement reports, channel quality feedback, and “comfort” noise information between different parts of the system.

  • Patent number: 6928073
    Abstract: The implementation of transactions on an integrated circuit comprising a plurality of functional modules connected to a packet router is described. Each functional module generates request packets for implementing memory access operations, each request packet having an operation field comprising eight bits of which a packet type bit denotes the type of the packet, four operation family bit denote the function to be implemented by the packet and three operation qualifier bits act to qualify the function.

  • Patent number: 6873617
    Abstract: The invention relates to equipment for call-completion analysis on high speed data links in an SS#7 network. A pyramidal structure service observing system processes data packets from all high speed SS#7 data links communicates directly with other service observing systems in order to create real-time call detail records and statistical reports. The first system which receives an initial address message signal has jurisdiction over a call. If a second service observing system receives data on the same call, that data is forwarded to the first service observing system in real-time so that interim call detail records may be generated while calls are still in-progress. While any suitable and available path may be used to forward the data, a wide area network or a local area network provides the preferred path.

  • Patent number: 6822970
    Abstract: A glassware forming system that includes a plurality of electronic devices for performing operations on articles of glassware. These devices may comprise devices for controlling the glassware forming operation by controlling one or more operating mechanisms of a glassware forming system, or may comprise devices for inspecting articles of glassware for commercial variations that may affect commercial acceptability of the glassware and call for possible adjustment or repair of the glassware forming system. A network interconnects the devices for intercommunication among the devices, and includes a star network hub and conductors connecting the hub to the plurality of devices in a star network configuration for bidirectional communication among the devices through the hub.

  • Patent number: 6798784
    Abstract: A network element can be configured for connection to any portion of a communication network: access, transport and core. Moreover, a single network element can be configured to couple subscriber equipment directly to the core portion of the network, thereby permitting the subscriber to bypass the transport portion of the network. Specifically, such a network element can be configured to include a line unit that supports subscriber equipment (also called a “subscriber line unit”), and also to include a line unit to support a link to the core of the communication network (also called a “core line unit”). The subscriber line unit and core line unit are both installed in a single chassis, and each unit can be installed in any of a number of slots in the chassis. Moreover, when configured with appropriate line units, such a network element may support traditional circuit-switched telephony services while simultaneously delivering packet-based voice or data services.

  • Patent number: 6751238
    Abstract: A large network switch has switch elements distributed across several chassis separated by perhaps several hundred meters. A generated sync pulse arrives at different switch elements at different times, creating skew. The latency of data through the network switch is set to match the frame period of SONET frames. SONET frames are adjusted at the ingress ports to align the data pointer to the beginning of the frame. The frame is divided along row boundaries into separate cell-packets that are routed across the switch fabric to the egress port. The packets are held in a buffer at the egress port until the next frame begins with the next sync pulse. Upon receiving the next sync pulse, the frame is transmitted. No pointer adjustment is needed by the egress port. A row number is used as a sequence number for the cell-packet to allow the egress port to re-order the cell-packets when transmitting the frame. Since no pointer manipulation is needed at the egress port, pointer management is simplified.

  • Patent number: 6717914
    Abstract: A system for probing one or more SVCs that enables a network manager station to setup a probe event in advance before a SVC is created. Upon the creation of the SVC, the data is captured and sent to the network management station without any further intervention required. In a first stage, a SVC originator is configured with a probing IE containing parameters to be included in the SETUP request message when SVCs are established. A unique identifier is included as one of the parameters in the probing IE and is used by the probing switch to detect a SVC that is to be probed. A PVC is established to the switch containing one or more SVCs that are to be probed. A probing port is configured on the switch and a range of VPI/VCIs are assigned to the port. A multicast connection is configured in the switch and traffic from the SVC originator is directed toward both the destination and to the probing port. In this fashion, the SVC traffic can be analyzed using diagnostic tools located remotely anywhere on the network.
