ABSTRACT:
A communication system includes at least two private branch exchanges which are each connected to a higher-level communication network and which are connected to one another through a hot-line link. A team-function controller in one private branch exchange performs a team function with respect to team terminals connected directly to that private branch exchange and with respect to team terminals, connected directly to the other private branch exchange, which are integrated into the team function in the form of remote subscribers through the hot-line link. Incoming calls to the team can reach the team controller through the network interface of the first communication system and through the network interface of the second communication system and a call diversion to the first communication system. In the case of a failure of the hot-line link, a team function subcontroller in the second private branch exchange cancels the call diversion and performs the control sequence of the team function for the team terminals connected to the second private branch exchange.
