XO Communications told me that the lines were functioning. I called them a couple of times yesterday evening. According to them, the could see my equipment connected and it was IDLE. I couldn't place a call into the thing to save my life but now I can. I'm just guessing really. Just thinking out loud. I'm not sure why it works not but did not before. Also, I am wrong. The modems do indeed answer. However, I noticed that before a call is connected, a 4 digit series of numbers is dialed by the channel bank before successful communication is established. I am not sure what is being dialed but after you hear it, the call connects. At any rate, I think the dialing is throwing off my modem and causing and interruption.
