| 摘要 |
A method is described for managing and propagating a failure indication in a telecommunication system. The telecommunication system comprises at least a synchronous transport network (TN) and a packet-switched network (ELB) which is connected to the synchronous transport network (TN) by means of a node (B) having a transport side towards the synchronous transport network (TN) and a packet side towards the packet-switched network (ELA). According to the invention, the method comprises the following steps, which are performed by said node (B): detecting a first failure (F) at the transport side (TN); performing consequent actions in the output direction at the packet side (ELB); detecting at the packet side (ELB) a second failure which is caused by said consequent actions; and ignoring the second failure. |
