ABSTRACT:
Communication system (KS) having a user facility system (LMS) for the realization of user facilities and having a switching system (VS) for setting up and clearing down connections between connected subscriber terminal equipment (TE) and for reporting switching-oriented events as well as user facility activation and user facility deactivation requests to the user facility system (LMS). The user facility system (LMS) has a plurality of user facility modules (LMB) and a user facility executive sequencer (LMAS) communicating therewith. The user facility modules (LMB) can call user facility development modules made available by the user facility executive sequencer (LMAS). Messages from the user facility executive sequencer (LMAS) about switching-oriented events occurring in the switching system (VS), is a facility activation and user facility deactivation messages as well as data input by subscriber terminal equipment (TE) are respectively communicated to a specific user facility module (LMB). Signaling messages for the subscriber terminal equipment (TE) are communicated from the user facility modules (LMB) to the switching system (VS). Dependent on an activation request, the user facility executive sequencer (LMAS) communicates an activation message to the specific user facility module (LMB) allocated to the activation request. Each user facility module (LMB) has a plurality of sub-controllers (R1, R2, R3) respectively controlling a message-dependent sub-execution, at least one coordination controller (RSC) forwarding messages coming from the user facility executive sequencer (LMAS) to the allocated sub-controllers (R1, R2, R3), and a call controller (ARS) for the calling of a coordination controller (RSC) dependent on an activation message.
