Abstract:
A method for controlling a changing of telecommunication channels of a telecommunication subsystem coupled into a telecommunication system as local information transmission loop, comprising the steps of:a) transmitting system information in the telecommunication system; b) allocating a plurality of subsystem channels for transmission of subsystem information and transmission of system information to the telecommunication subsystem; c) allocating first and second telecommunication interfaces, that are connected to one another at least via a subsystem channel of the subsystem channels, to the telecommunication subsystem; d) coupling the telecommunication subsystem into the telecommunication system via the first and second telecommunication interfaces; e) transmitting information on the subsystem channel of the subsystem channels; f) transmitting a switch-over command such that one of the first and second telecommunication interfaces signals to the other telecommunication interface that the information is to be transmitted on another subsystem channel of the subsystem channels; g) transmitting a switch-over response by the telecommunication interface receiving the switch-over command-to the telecommunication interface sending the switch-over command; and h) interrupting the transmission of the information before, with or after the transmission of the switch-over command and resuming the transmission of the information with or after the transmission of the switch-over response; wherein the transmission of the information is interrupted immediately after the transmission of the switch-over command and wherein the switch-over response is transmitted substantially immediately after the transmission of the switch-over command.
