I can tell you what I know about this particular model, or my understanding of it. This channel bank is a Carrier Access model. CAC Bank I. As far as I know, it can only carry voice transmissions. The CAC Bank II can do voice and data. At any rate, I do have the bank plugged into the T1 jack and all looks good. That is until I call a phone number associated with the T1. Then I get busy signals. All lights are solid green aside from the STATUS light that flashes green. Additionally, I do have the bank connected to a punchdown block that is running to my IVR server. Everything is connected but I have not been successful in getting a call throught yet. Know of anything I should try? Any tips you might have?

Greatly appreciated
Thank You
