Intecon how did you make out with your configuration of both the RTI and URC in the same system? I might be running into the same issue as you. I have an MX3000 with an MRF-300 if I need one and then a T2-C that will be incorporated with a T1 and and RP1. Will have to play with it a little bit to make it work.

Would be interested in hearing how you made out.
