A method of creating/terminating a connection associated with an end-to-end path defined through a communications network. According to the invention, cross-connection download/undownload processes in each intermediate node of the end-to-end path are triggered substantially in parallel. A confirmation message indicative of successful completion of respective download/undownload processes in each intermediate node is subsequently propagated to an end-node of the path.

Connection creation/termination using parallel cross-connection download/undownload processes

Commands are shown and described that enable a user to manipulate a call connection for the purpose of maintaining links in a network. The Block command prevents new traffic from being added to an output port of a device in a connection. The Forced Restoration/Release of Forced Restoration command set may be used to service the working channel. The Lockout of Restoration/Release of Lockout commands provide an alternative method of servicing a working connection and preventing unnecessary generation of redundant connections in the network.
