This is not one of my strengths. I have read all the redbooks on it. My understanding is that TCP/IP on z will/can use FICON/ESCON (CTC) to talk to another z.
But, it doesn't say directly, that OSA is required for other platforms. It implies it by showing configs using that. Never shows a FICON (ESCON) connection to the world beyond z. I've read all I can (understanding little), and the question is: Can I use FICON (ESCON) connections to talk to alternate platforms? Do I want to? Or, is OSA the way to do it? When in doubt.
