Note: CTC and CNC are from ESCON world. Ideed, that required different
CHP definition on each end.
Nowadays we have FICON and FC chpid definition on each end.
The topology may be
FC CHP 1A ---- FC CHP 1B
or
FC CHP 1A ---- switch.
1A and 1B ard example values of th CHPID.
Of course for redundancy any of examples above can be doubled, tripled,
quadrupled...

4 ficon ports(CHPIDs) and 2 ficon cables are required. Each cable is shared in
a bi-directional manner.
e.g CTCchipd1 <----> chpid2 CNC Signalling Path 1
CNCchpid3 <----> chpid4 CTC Signalling Path 2

no switches exist at the site.
I can't see how to share the CTC and NON CTC Control units on a Ficon card, it (HCD)
keeps generating a message that you can't "share" CTC and NON CTC on the same
CHPID, but maybe I'm doing something wrong.
