Method and device in a coupling node for a telecommunication system

A coupling node in a telecommunication system for coupling of communications in the telecommunication system, said coupling node comprising:

• connections for the communications and a connection for a server;
• function devices with functions intended for the communications, the functions being supported by carriers, wherein the function devices are by the carriers arranged in a hierarchic structure;
• processors supported by the carriers;
• a selector device being arranged to couple, after a signal from the server, at least a first of the functions, wherein the selector device is arranged to, at the coupling of at least one of the functions, on one hand hunt for a first one of the processors being a candidate for handling said at least one of the functions, on the other hand investigate whether the hunted processor has resources in the form of sufficient free space in its data store and in its instruction memory and sufficient processor capacity for the handling,
• the coupling node comprises internal communication resources for the function devices;
• the function devices each having their own hierarchic address, corresponding to the hierarchic structure of the function devices, and the selector device being arranged, by means of the hierarchic addresses to select two of the function devices for one of the communications within the communication consecutive of said functions in such a way that the amount of internal communication resources being utilized for connecting said two function devices, is limited.
