Abstract
A requesting terminal signals a call request (CALL) to a control unit of a first communications network. The control unit then determines whether sufficient capacity is available in the first communications network to establish the connection requested by the call request. In the event of insufficient capacity, the control unit transmits an overload message (DAT) to the requesting terminal. It only initiates an alternative establishment of the requested connection via another, second communications network after it receives an acknowledge message (ACK) issued by the requesting terminal.
