There is only one restriction: it can't be done.

You can't connect 2 SSCPs with more than one "channel" TG.
If you try to define two CTCAs, both of them are being defined
as TG1, so only one of them can actually be working at a certain
point in time. (Incidentally, the funny thing is that under most
circumstances you *will* be able to define and sometimes even
ACTivate both CTCAs - but rest assured only one of them really works..
I worked like this for over two months, being positive that I'm making the
best out of my two CTCAs - until an IBM SE that insisted on "it can't
be done" forced me to check - and guess what I found, to my - or IBMs
- disgrace..).

Note: this only talks about connecting of two specific SSCPs with
more than one channel-attachment TGs. Obviously one SSCP can talk
to more than one CTCA - if their "other ends" are connected to
different SSCPs.
