Thanks Dex and SST. Honestly, I am not sure either. Here is the solution I am proposing and thinking will work: Use a MX2800 M13 Multiplexor with an AC Power Supply. Use an RJ patch panel to break down my 28 T-1's w/ a 64 pin to 64 pin cables. Then use 2 coax cables to connect that to the DS3. Sound good? Also I think we will get the ds3 with the SS7 signaling to run sf D4 AMI so my equipment will interface with it. What do you think? And if I have trouble with the wiring will you guys be able to give advice? You guys are the s***! Thank you!!! oh, and there is a B8zs to AMI converter out there! I had to use it on a bad install from ITC Deltacom. (They installed B8zs wehen we REPEATEDLY requested D4 AMI).
