摘要： A system for selecting bus mastership in a multi-master system includes master devices and at least one slave device. The master devices generate control signals relating to bus mastership in the multi-master system. The slave device(s) receive the control signals from the master devices, determine whether a conflict exists based on the control signals, generate one or more alternate control signals for selecting bus mastership when a conflict is determined to exist, and select bus mastership using the one or more alternate control signals.

摘要： In a digital switch, incoming cells are placed into a queue in a cell memory. The switch maintains various cell queues, including VC queues that correspond to individual connections and QBin queues that correspond to various classes of service. Cells may arrive to a VC queue or a QBin queue but will depart from a QBin queue. Accordingly, cells may be moved from VC queues to QBin queues. Cells are serviced according to the use of QBin Groups. A QBin Group (QBG) includes a number of logical queues (QBins) of cells to be transported in the digital network. After a QBG is selected, one of its logical queues is selected for servicing. The QBG may be selected by examining all of the QBGs to find an eligible QBG which is most overdue for service. A QBin of the selected QBG may then be selected by examining each of the QBins comprising the selected QBG to find the most overdue for service. The QBGs may correspond to virtual interfaces.

摘要： A removable apparatus for carrying a circuit board includes a carrying plate having a notch to receive a stationary pin of an enclosure and a faceplate connected to one end of the carrying plate. A rotating cam connects to the carrying plate and acts on the pin to move the apparatus relative to the pin during insertion into and removal from the enclosure. The cam includes two different surfaces, each of which acts to move the apparatus either into or out of the enclosure. A linkage is connected to the cam and extends through the faceplate, connecting to a lever on the exterior of the faceplate. The lever is used to rotate the cam, which in conjunction with the pin provides translational motion either to mate a connector on the circuit board with a corresponding connector in the enclosure or to separate the mated connectors, depending on the direction of rotation.
