For upgrading a section of a telecommunication network comprising two nodes (1, 2) one (4) of data lines (3, 4) interconnecting the nodes is selected to be carrier of redundant specimens of information units to be transmitted. An external condit For upgrading a section of a telecommunication network comprising two nodes (1, 2) one (4) of data lines (3, 4) interconnecting the nodes is selected to be carrier of redundant specimens of information units to be transmitted. An external condition is fulfilled, which is detected by a control unit of the node and causes the control unit to block changes to connections going via the line (4). In this state, the interface circuits (14, 24)) of nodes (1, 2) connected to the selected line (4) are replaced by more powerful ones (14', 24'), and the condition is unfulfilled again. The method is repeated for the other data line (3).

Pour l'actualisation d'une section d'un réseau de télécommunication comportant deux noeuds (1, 2), une (4) de deux lignes de données (3, 4) interconnectant les noeuds est sélectionnée pour être la porteuse de spécimens redondants d'unités d'information devant être transmises. Une condition extérieure est remplie, ladite condition étant détectée par une unité de commande du noeud et amenant l'unité de commande à bloquer des changements de connexions s'étendant au travers de la ligne sélectionnée (4). Dans cet état, les circuits interfaces (14, 24) de noeuds (1, 2) connectés à la ligne sélectionnée (4) sont remplacés par des circuits plus puissants (14', 24'), et à nouveau, la condition n'est plus remplie.
