  • Patent number: 9451338
    Abstract: An interface is proposed to couple a network processing device and at least one data pump device. The interface is of a serial type and is operable to transfer data chunks of a predetermined data chunk format comprising a channel address field indicating a logical channel the data chunk is assigned to.

  • Patent number: 7369568
    Abstract: An ATM-port module for an ATM-node having an Ethernet switch includes an ATM-controller; and an Ethernet-switch interface connecting it to the Ethernet switch. The switch has an Ethernet encapsulating-unit for encapsulating ATM cells processes by the ATM-controller into packets for transmission to the switch, and an Ethernet decapsulating-unit for extracting ATM cells from packets received from the switch. The module further includes a segmentation-and-reassembly unit; and a buffering-and-scheduling unit. The buffering-and-scheduling unit provides a processed enlarged-ATM-cell to the encapsulating-unit when an indication flag indicates that an ATM port is a destination port of the enlarged ATM-cell; and a processed enlarged-ATM-cell to the segmentation-and-reassembly unit when an indication flag indicates that an Ethernet port is the enlarged ATM-cell's destination port.

  • Publication number: 20040096583
    Abstract: A method for manufacturing workpieces treated in a vacuum includes providing first and second vacuum chambers having first and second vacuum pumps, respectively. A vacuum is generated in the first and second vacuum chambers using the second vacuum pump. The second vacuum pump is connected by valves between the first vacuum chamber through the first vacuum pump and the second vacuum chamber. The valves are operated to evacuate the second vacuum chamber, followed by processing the workpieces in the first vacuum chamber.

  • Patent number: 6669987
    Abstract: A lock chamber (1) is isolated from the environment (U) by a lock-valve (3) and from a vacuum chamber configuration (7) by a lock valve (5). A turbo vacuum pump (13) acts upon the vacuum chamber configuration (7). An additional pump (9/15) is switchably (17) connected downstream from the pump, which switchably operates either as a prevacuum pump for the turbo vacuum pump (13) or as lock chamber pump.

  • Patent number: 5583849
    Abstract: An ATM communication system (ATMK) has communication equipment (K1, K2, K3) that are arranged in a ring circuit system (RS) formed of two ring circuits (RING0, RING1) operated in opposite directions. Ring loops can thereby be established via the communication equipment in order to be able to switch from an active path to an alternate path as needed in the transmission of message cells. In the respective communication equipment, the message cells are respectively preceded by an internal cell header wherein, among other things, a path-associated sequence number is contained. Over and above this, the sequence number anticipated next or, respectively, the sequence number that most recently appeared is retained and path-associated in the respective communication equipment.
