ABSTRACT:
The present invention is directed to a switching device and to a pertaining method for parallel connection of subscriber terminal devices having complex performance features. Subscriber terminal devices connected in parallel are thereby driven in an interface driver via a principal subscriber control and at least one subsidiary subscriber control. Due to the realization of a logical and physical interface between the principal and subsidiary subscriber control, the subscriber terminal devices are connected to one another both connection-oriented as well as with respect to their performance features.
