We have two CTCs between an old VM/ESA system and an even older OS/390
system running on separate physical processors. One of the CTCs
connects the TCP/IP's on these systems and the other connects VM's RSCS
to OS/390's JES2.
The relevant bit of the VM IOCDS:
CHPID PATH=(BB),TYPE=CTC,SWITCH=01
CNTLUNIT CUNUMBR=BB10,PATH=BB,LINK=FA,UNIT=SCTC,UNITADD=((10,16))
IODEVICE ADDRESS=(BB10,16),CUNUMBR=BB10,UNIT=SCTC,UNITADD=10
In HCD, the corresponding CHPIDs are defined as CNC, the Control Units
as SCTC, and the Devices as BCTC.
In the VM TCP/IP config file, I have:
DEVICE CTCDBURO CTC BB10
LINK CTCLBURO CTC 0
and in OS/390:
DEVICE CTCDVM1 CTC BB10
LINK CTCLVM1 CTC 1 CTCDVM1
I don't know if that helps, but it works for us!

Roy Harrop

Subject: Re: real ctc vs vctc on tcp/ip
maybe it's 'cause you are trying to attach ctc and cnc type chpids?
Also from TCPIP Planning and Config:
"If you are using HCD on OS/390 or z/OS, these devices must be defined
as "CTCA" on the VM side, and "SCTC" on the OS/390 or z/OS side"
