Communications installation with communications terminal equipment provided with prescribed functions defined and controlled by a communications installation with information transmission

摘要

A communications system with communications terminal equipment provided with prescribed functions that are defined and controlled by a communications installation by information transmission. An identical parameter-controlled program for all communications terminal equipment connectable to a communications installation is stored in the program memory of the communications terminal equipment. All functions that can be allocated to the different types of communications terminal equipment are realized by this program. The functions provided for the respective communications terminal equipment are allocated and controlled by parameter data stored in a data memory. On the basis of an initialization in the communications terminal equipment or in the communications installation, the parameter data are transmitted for the first time to or updated at the respective communications terminal equipment by the communications installation. In a communications system fashioned in this manner, the terminal-associated, flexible allocation of functions and procedures to the respective communications terminal equipment is preserved despite the displacement of switching-oriented and operations-oriented functions into the communications terminal equipment, which means a dynamic relieving of the central controller of the communications installation.
