There is described a telecommunications network (3) having nodes (4-16) which are mutually coupled using communication links. The telecommunications network (3) has a tree structure. It comprises at least three node layers, namely a first node layer of a lowest level, comprising a number of nodes (11, 12, 13, 14, 15, 16), which nodes form the leaves of the tree structure, a second node layer of a higher level, comprising a number of nodes (5, 6, 7, 8, 9, 10), and a third node layer of a still higher level, comprising at least one node (4, 5, 6). The node (4, 5, 6) from the third node layer comprises transmitter means (18) for transmitting a signalling message (100) in the downward direction. The node (4, 5, 6) further comprises addressing means (24) for feeding, to the signalling message, a node designation (103) of a node (11, 12, 13, 14, 15, 16), from the first node layer associated with the siganlling message, and a type code (102) which designates a control function of a specific type, or a node of a specific type for which the signalling message is intended. |
