Abstract

A coordination system coordinates connection requests of a modular connection system to a switching control system. The connection system controls connections at a logic level, and the switching control system controls connections at a physical level. Coordination modules have the following elements. A receiver receives and buffer-stores connection requests produced from the connection system for an active connection end point involved with a connection. A connection request, which is buffer-stored by the coordination modules, is passed on to the switching control system when the coordination modules have received control over an active connection end point. Control over a specific active connection end point is surrendered to one another such that only one coordination module has control over this specific active connection end point at a specific point in time.
