Method for operating a telecommunications system, and a telecommunications system in which the method can be used

The invention relates to a method for operating a telecommunications system having a switching station (BS) and a plurality of internal subscriber stations (HA1, HA2, HA3, HA4) which are connected to it and with whose aid the switching station (BS) can simultaneously operate a limited number of channels of the same or a different type and is characterized in that the switching station (BS) reports to all the internal subscriber stations (HA1, HA2, HA3, HA4) by transmitting a respective busy signal that a channel of the appropriate type is not available, each internal subscriber station (HA1, HA2, HA3, HA4) is changed by the busy signal to a state in which it cannot initiate a connection being set up on the corresponding channel. It furthermore relates to a telecommunications system for carrying out the method, which is characterized in that the switching station (BS) contains a signal generator (SG) which produces a respective busy signal and sends it to all the internal subscriber stations (HA1, HA2, HA3, HA4) when a channel of corresponding type is not available, and each of the internal subscriber stations (HA1, HA2, HA3, HA4) contains a blocking device (B), which can be driven by the respective busy signal and, on reception of the respective busy signal, changes the internal subscriber station (HA1, HA2, HA3, HA4) to a state in which it cannot initiate a connection being set up on the corresponding channel.
