Abstract: A data communication network provides techniques for handling frame discard of non-delineable flows. When a data flow is established, it is evaluated to determine whether a frame delimiter value is required and, if so, whether it is present. If the frame delimiter is required and missing, then the flow is declared non-delineable. If, subsequently, a congestion threshold is reached for this data flow, cells are discarded until a) a frame delimiter value is received, b) congestion drops below the threshold or c) a predetermined number of cells are discarded. These techniques provide frame discard handling mechanisms that alleviate the need for NOC personnel to intervene in problems caused by non-delineable frame discard flows.

Abstract: The invention relates to a network comprising a plurality of network nodes. At least part of the network nodes are directly coupled to each other via at least one star node. The star node comprises a plurality of star interfaces which are assigned to at least one network node. In dependence on a respective pilot signal, a star interface conveys a message from the assigned network node to the other star interfaces, or from another star interface to at least one of the assigned network nodes. Also in the event of simultaneous arrival of at least two pilot signals at the respective star interfaces, a decision circuit releases one star interface for the transmission of data.

Abstract: A control apparatus controls the display of text data which includes a speech link that can be activated by spoken command. The shape of a pointing device cursor displayed on a display is then changed by the apparatus when the pointing device cursor is located over the speech link included in displayed text data. The apparatus is arranged to output a prompt identifying speech commands that can be used to activate the speech link if the pointing device cursor is displayed on a display located over the speech link in a changed state for a predetermined time.

Abstract: An integrated circuit for a smart card may include a transceiver for communicating with a host device and a Joint Test Action Group (JTAG) test controller for performing at least one test operation. Further, the integrated circuit may also include a processor for causing the JTAG test controller to initiate the at least one test operation based upon receiving at least one test request from the host device via the transceiver. More particularly, the processor may convert the at least one test request to JTAG data for the JTAG test controller. That is, the integrated circuit advantageously allows communications between the host device and the JTAG controller via a system bus, for example, without the need for a dedicated JTAG test access port (TAP) which is typically required for accessing JTAG controllers.

Abstract: The invention relates to a network comprising a plurality of intercoupled network nodes. Controlled by a bus guardian the network nodes transmit messages during a respectively assigned time slot and receive messages from other network nodes outside this time slot. Each network node comprises a test signal generator which delivers a test signal outside the respectively assigned time slot, and includes a test signal detector which detects outside the respective time slot, after receiving a test signal from at least another network node, that there is a defective circuit portion in the assigned network node and/or in at least another network node.

Abstract: Embodiments of the invention may provide a method for implementing an adaptive multimode media queue. A mode of operation may be determined for a received media stream based on a sampling rate of the media stream. The mode of operation may be a wideband mode and/or a narrowband mode. Depending on the determined mode, the adaptive multimode media queue may be partitioned into a low band media queue and a high band media queue. A wideband media stream split into a high band and a low band is buffered into the adaptive multimode media queue wherein the high band is stored in the high band media queue, and the low band is stored in the low band media queue. The high band media queue and low band media queue may be a contiguous memory block within the adaptive multimode media queue. The received media stream, which may have different sampled data rates may be buffered within the partitioned adaptive multimode media queue.

Abstract: The present invention is directed to a method for defining a meshing of node to node connections in a communication network comprising a plurality of nodes interconnected with transmission links or parallel transmission groups, each parallel transmission group comprising a plurality of links.

Abstract: A network communication system sends identical information from a source node to a plurality of destination nodes by first sending the information from the source node to a predetermined relay node, then sending the information from the relay node to the destination nodes over predetermined communication paths. The predetermined communication paths connect the destination nodes to the relay node in a star topology. The star topology greatly simplifies the routing of the information, while automatically avoiding looped paths, and enables the identical information to arrive at all destination nodes in real time, substantially simultaneously.
