Jan,
I just tested it and its possible.
I can assign same ring numbers for 2 Trcrfs in different Trbrfs

Please respond to
"John White"
I guss something went wrong on that switch, because my experience was
quite opposite.The switche didn't allow me to use the same ring # for the
same TrCRF for the second router.I had to use different ring number and
everything worked fine.
Next week I will have access to TR switch so I'll test it again.
What you say is logical and make sense
Thanks
Jan
