Abstract
A method and an arrangement are specified for setting up and clearing communications links via a private branch exchange. A number of types of communications device are driven via the same controller. New devices with a transport network for transporting the communications data can thus be integrated in a private branch exchange by using TDM-based devices. The central configuration of the controller allows already existing central interfaces and databases relating to subscribers to be used. If required, service feature controllers can still be used.
