A broadcast call is made to all network element, and a connection via a free path is set up. The network is logically structured in a hierarchy with at least two multiplex layers, each network element having access to at least a part of the layers. Tests are performed to check which of the multiplex layers is suitable for establishing the connection. The broadcast call is forwarded via existing connections of the suitable multiplex layers to which the forwarding network element has access. A network element for carrying out the method is also claimed. |
