Abstract

A hierarchical network management system is described which includes concentrators (2A to 5A) on the individual levels (E1 to E3) of the hierarchy as well as adjustable interfaces in the concentrators for point-to-point and bus connections. An interface is provided for a bus connection on a master side. The interface takes delays into consideration. A transmission channel can be connected to the interface. The channel includes a forward bus and return line (a5, b5). Parallel addressable apparatus (8A, 8B, 8C) can be connected to the forward and return lines. A controllable change-over switch (A8, B8, C8), inserted in the return line (b5) of the transmission channel, is provided for each addressable apparatus (8A, 8B, 8C) of the parallel combination.
