Abstract: A network element for a digital transmission network is proposed. The network element contains two switching matrices for switching data cells, as well as ingress ports that receive TDM traffic flow and packet traffic flow and segment the traffic flows into cells. A control system for controlling the configuration of the ingress ports and the switching matrices controls the ingress ports, in case of no failure of the switching matrices, to forward the TDM traffic flows to both switching matrices and to split the packet traffic flow over the two switching matrices.

Abstract: A quality of service session is established between a correspondent node and a mobile node. The mobile node has a home address in a home network is temporarily connected at a care-of address in a foreign network. A modified reply message is generated in the foreign network. The modified reply message has a source address of the mobile node's care-of address and a destination address of the correspondent node. The modified reply message is then transmitted. A capable of supporting such a quality of service session is also disclosed.

Abstract: A method for identifying an error cause affecting the configuration of a network element (110) controlled by a network manager (100) is described. The method includes the step of transmitting from the network element (110) to the network manager (100) a message (5) including a first field (30, 40) for indicating if a configuration error occurs in the network element (110). The message further includes a second field (50) for indicating the configuration error cause, wherein the configuration error cause is dynamically selected out from a configuration information stored into the network element (110).

Abstract: It is disclosed a method for collecting data from nodes of a telecommunication network, said network comprising a collecting node and an intermediate node, the method comprising the steps, which are performed by the intermediate node, of: receiving from said collecting node a first file comprising at least a first compressed data set and a first dictionary; generating a second file comprising at least a second compressed data set and a second dictionary; merging said first dictionary and said second dictionary into a resulting dictionary; and inserting said resulting dictionary, said first compressed data set and said second compressed data set into an overall file. Also disclosed are a network node and a network manager for implementing the method.
