Abstract:
A method for controlling setting up of telecommunication connections in telecommunication subsystems serving as local message transmission loops of telecommunication systems and having network terminations which differ with regard to the transmission channel requirements, comprising the steps of:a) transmitting system messages on system channels in the telecommunication systems; b) providing the telecommunication subsystems with a plurality of subsystem channels for transmitting subsystem messages and the system messages; c) providing the telecommunication subsystems with telecommunication interfaces, which are connected via network termination-specific subsystem channels to second telecommunication interfaces and/or third telecommunication interfaces, which are structured as network terminations, and also via network-specific subsystem channels to the system channels; d) incorporating the telecommunication subsystems into the telecommunication systems via the telecommunication interfaces; e) providing the network termination-specific subsystem channels with signalling channels and user data channels; f) transmitting the messages from and to the second telecommunication interfaces via the signalling channels and/or the user data channels, and transmitting the messages from and to the third telecommunication interfaces via the user data channels; g) transmitting first subsystem messages having first parameters from the second telecommunication interfaces and/or the third telecommunication interfaces to the first telecommunication interfaces, for connection setting up; h) transmitting the first parameters of the first subsystem messages having first parameter values containing contents â€œSIGNALLING CHANNEL ONLYâ€  from the second telecommunication interfaces to primary telecommunication interfaces of the first telecommunication interfaces; i) connecting the signalling channels to first channels of the network-specific subsystem channels for connecting the signalling channels to the system channels and/or for routing of the signalling channels of the telecommunication subsystem to the telecommunication systems.
