• 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 these structures for outbound use.
  Note: Unlike a CTC device, a signaling structure can be defined for simultaneous inbound and outbound use.
• PATHIN DEVICE(8C0,8C1,8C2) - defines inbound signaling paths 8C0, 8C1, and 8C2.

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 IXCNEW and/or a signaling CTC device (such as 200) as pathout from SYSB to class TCNEW.
