Disclaimer: I have no direct experience with T1. However I do have experience with networking going back to the early 1980's.
If I would want to do what you describe (and I am trying to learn so that I can do similar things), I would subject myself to the Panasonic KX-T training. According to the Panasonic sales rep, the training does not cover ISDN-BRI (which is still in the notes) but does does cover T1. I wonder how the phone systems will connect to the PSTN? The KX-TD1232 system has a limitation of 8 POTS lines when a T1 is installed. If I were purchasing expensive, and hard to get Cisco T1 cards, and planned to connect them to the LEC, I would be happy to pay for relatively-cheap, external CSU/DSUs that might be fried by something unexpected. But I think that the CSU/DSU problem has already been handled for the data connection. I think that you would need additional CSU/DSUs if you wanted one or more T1 connections to voice PSTN from the Cisco Router. The ring voltage and talk voltage are irrelavant for the T1 connections. >From what I read, the Cisco router already connects to the two sites via T1 connetion via the LEC, so you need: - physical connection between the KX-TD1232 T1 cards and the Cisco at each location. - configuration on both Cisco routers on each location to assign some channels to voice TIE lines. It would be way cool if these channels would be dynamically assigned, and perhaps compressed to have 10 voice channels in a DS0 (as with some satellite leased-bandwith applications). - configuration on the KX-TD1232 with T1 cards on each location. Good Luck!
