To implement signaling paths through list structures, you specify a list structure for use as PATHIN or PATHOUT and MVS™ automatically establishes a corresponding inbound or outbound path with all the systems that have specified that structure for pathout or pathin.

To implement signaling through a list structure, you need to specify (on the STRNAME keyword of the PATHOUT and PATHIN statements in COUPLExx) the name of the structure, defined in the CFRM policy, that holds the signaling path connections.

To implement signaling through a list structure, define the structure as both an outbound and an inbound path on every system connected to that facility. MVS creates one path in each direction for each path defined.
