Abstract: Disclosed is a movement transfer mechanism, a drive assembly and a system for transferring reciprocating linear movements into a rotary movement of a shaft. The transfer mechanism comprising a connecting member, first and second engaging means fixedly connected to the connecting member and first and second drive units, each comprising ball bearings with respective inner rings and outer rings, wherein the outer rings are fixedly attached to gear wheels. Each gear wheel is engaged with the respective engaging means. The invention is characterized by that the respective inner ring of the respective ball bearing is arranged to be fixedly connected to a first shaft, and further that the first drive unit and the second drive unit are arranged with a backstop and by that the respective outer ring is locked relative to the respective inner ring in a first rotational direction and unlocked in a second rotational direction which is an opposite direction relative to the first direction.

Abstract: A telecommunications switch is provided with an internal ethernet link which is connected to a group switch/time switch portion of the switch through a number of interface processors. The group switch/time switch portion functions to switch data communications among and between the subscriber lines, trunk lines and the interface processors. The ethernet link serves as a concentrator for packet data communications carried over the subscriber/trunk lines and handled by switch. The interface processors operate to selectively insert and extract packet data communications to and from the ethernet link. A connection is made via the ethernet link to an Internet access point to allow concentrated data packet communication with the Internet.
