The model number for the Carrier Access Bank I is 900-0075. As far as the IVR goes. It actually is a Multitech ZDX Rack. 12 standard Multitech external modems can be placed inside. The 12 modems are data voice fax modems. Additionally, I have another rack that contains 12 more modems. I was going to combine them and connect them both to the channel bank using the punchdown block. The block consists of 24 ports and with the two modem racks I will have 24 ports to work with. As far as the 40 DID numbers, that is the way that XO provisioned them for me. True I can't use all the numbers but they couldn't give me just 24. It was either 20 or 40. So they kind of backed me into a corner on that one. So I chose 40. In your previous post you use an acronym RNA : What does this stand for?

Thank you again
