No this actually requires a real CTC, if you have a test system, and have a spare CTC device address Then you are OK, but connecting 1st Level to 2nd Level, I believe, for ISFC is not supported.

I've used VCTC between guests for years. What I needed, but apparently is not supported is a VCTC, connecting CP to a virtual machine for ISFC links.

On first level, define one Virtual CTC (FCTC, SCTC) into TCPIP (or another capable machine) to connect to second level VM. On second level VM, define and couple the Virtual CTC to first level TCPIP before his IPL (COMMAND into Directory is a good place to set it). After the IPL, DEDICATE the CTC (the second level thinks it is a REAL CTC) to his TCPIP machine. Done, you have the two TCPIPs connected by CTCs... Work fine also for VTAM machines, RSCS, PVM, zOS and so long... ______________________________________________ Clovis Pereira Error!
