摘要： Apparatus and methods for communication system-level communication link bonding are disclosed. Multiple communication links provided by transceivers in communication link termination modules are configured as a bonding group to support an aggregate group communication traffic rate on another communication link. Through an internal communication mechanism in communication equipment, communication traffic received on the other communication link is distributed among those of the communication link termination modules which include transceivers for transferring communication traffic on the communication links in the bonding group. The bonding module also receives, from communication link termination modules, communication traffic to be sent on the other communication link.

摘要： In a switching network with a plurality of inlets and outlets and a plurality of interconnected switching nodes having inputs and outputs with respective addresses, a method is described of modifying a first set of outlets to which a cell stream is routed from one of the inlets to a second set of outlets to which this cell stream is to be routed, the addresses of the outputs of each switching node from which the cell stream is output being stored in a routing table of the node. The method includes the steps of transmitting a modification request message to the inlets from each outlet belonging to one but not to both sets and in each switching node receiving the modification request message on one of its outputs, selectively transmitting the request message to the inlets or transmitting a confirmation message to the above each outlet depending on the absence or presence in the node routing table of addresses of node outputs other than the one node output, respectively.

摘要： The device controls at least one accessory which operates in an intermittent manner and is driven through a connection by the engine of the vehicle. The latter has a hydraulic steering assistance supplied with fluid under pressure through a delivery pipe by a pump which is driven by the engine through an electromagnetic clutch. A fluid pressure-switch is connected in the electric circuit of the clutch and inserted in the delivery pipe and cuts off the aforementioned connection when the delivery pressure of the pump reaches a predetermined threshold value.

摘要： An ATM network, in which the downward data rate, from the network to the users, is greater than the upward data rate, from the users to the network. Multiplexers are provided for establishing connections, constituting virtual channels, between users and the network; the virtual channels are grouped into virtual paths. In each multiplexer close to the user, the bandwidth allocated to each downward virtual path is variable under the control of a call control means provided upstream in a switching node, and the upward virtual channels have a fixed bandwidth. Preferably, in the downward direction, each virtual channel is assigned a permanent or semi permanent quality of service.
