Abstract: An ATM-port module for an ATM-node having an Ethernet switch includes an ATM-controller and an Ethernet-switch interface for connecting the ATM-controller to the Ethernet switch.

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.

Abstract: An improved guide rail arrangement especially adaptable for vehicle power seats includes a pair of interleavable guide rail assemblies that are individually bolted to the vehicle seat and to the vehicle floor. The fixed guide rail assembly includes a C-shaped member extending upwardly into a guiding space that is formed between the parallel, downwardly projecting legs of a pair of U-shaped rail elements forming the movable rail assembly. A plurality of spaced, horizontally disposed alignable apertures are respectively incorporated in adjacent legs on one transverse side of the interleaved guide rail assemblies. Horizontal movement of the movable rail assembly with respect to the stationary assembly is stopped in a novel way by incorporating a pair of blocking plates symmetrically supported on transversely opposite sides of the longitudinal axis of rail movement.
