Abstract
Method for extending the crankback procedure in an Asynchronous Transfer Mode (ATM) system composed of at least a first data network (10) comprising a plurality of switching nodes interconnected by connection lines and including end switching nodes each being connected to at least a Data Transmission equipment (DTE) and being used either as an entry border node (22) when it is connected to a source DTE (18) or an exit border node (28) when it is connected to a destination DTE (20), the network using a routing protocol of the type wherein a best route between a source DTE and a destination DTE is determined in a control point associated with the entry border node to which is connected the source DTE and wherein a set-up message is sent by the entry border node, and a second data network (12) including at least one DTE to be used as destination DTE in an exchange of data with a source DTE connected to the first data network and being interconnected with the first data network by means of at least two links (14, 16) not supporting the routing protocol. Such a method consists, when the exit border node of the first data network receives a clearing message on one link indicating that th…
