CSU/DSU in 2270R??

[nyopt]

How do you use the CSU in the 2270R. I see no output for the voice channels?? Should I use an external csu/dsu? If so how to I get the data channels into the router? Because now the t-1 goes from the smartjack right into the 2270R w0 port (RJ-45), if I use a external CSU/DSU the data will come out of it in a V.35, what cable will I need to convert it to the RJ-45? Any help would be RRReally apprciated!!!

What exactly are you trying to accomplish?

I'm trying to take 2 channels of the t-1 for voice. To do this i need the t-1 to hit a csu/dsu to seperate the channels.
