<p>It is disclosed a telecommunication system (TS) comprising a transport network (TN) and a user network (UN). The transport network comprises a first edge node (PN) and a second edge node (SN). The user network is connected to the transport network by means of the first edge node and the second edge node. The first edge node comprises a first user section (uSp) and a first transport section (tSp), and the second edge node comprises a second user section (uSs) and a second transport section (tSs). The first transport section is connected to the second transport section and it is switchable between at least two of: a first status, wherein it connects the first user section and a first node of the transport network; a second status, wherein it connects the first user section and the second transport section; and a third status, wherein it connects the second transport section and the first node of the transport network.</p> |
