• PATHIN STRNAME(IXCDEF,IXCAPP) - defines signaling structures IXCDEF and IXCAPP for inbound use. Inbound signaling paths will be established with every other system that defines this structure for outbound use.
  Note: Unlike a CTC device, a signaling structure can be defined for simultaneous inbound and outbound use.

In the example, the COUPLExx parmlib member on SYSB could also define a TCNEW transport class, assign the NEWAPP group to TCNEW, and assign structure IXCAPP as pathout from SYSB. In such a configuration, all NEWAPP signaling traffic in the sysplex would be preferentially sent via the IXCAPP structure, and all other signaling traffic in the sysplex would be preferentially sent via the IXCDEF structure.
