A great way to do this that takes a little setup is to do the following: Set up a real channel-to-channel on your system with two addresses that talk to each other on the same LPAR. A virtual channel-to-channel will not work with a first-level system.
DEDICATE or ATTACH one end of the CTC to your second-level system. Start up an ISFC connection between first and second level over the CTC. This requires only two CP commands, One command on each system. Set up the first level shared file pool server as a remote filepool. Then you can trade files back and forth using this filepool. I've been doing this for years and it works great! "Christmas is a funny season. What other time of the year do you sit in front of a dead tree and eat candy out of your socks?"
