Abstract Call Status Recognition in a Broadband Private Automatic Branch Exchange In a broadband private automatic branch exchange (BB-PABX) in which a plurality of broadband terminals (BB-E1, ..., BB-E26) are connected to a broadband switching array (BB-V) to switch video and data signals, the current call status of the system must be signaled to the terminals, so that a broadband connection may be activated For this purpose, a message characterizing a quiescent state is supplied to one input/output (0) of the broadband switching array (BB-V) of the private automatic branch exchange and all nonswitched input/output (1, 2, ..., 30) controlled by an associated control unit (C) are linked with the first input/output (0) so that the quiescent state message is always transmitted to all nonswitched terminals
