Sorry to get in on this thread so late, have been out of the office. I will PM you a PDF version of the manual for that Access I channel bank. 95% of everything you need to configure is printed on the flat face of the box. It does sound like you have it configured correctly, though I would have you check the dip switches at the back of the unit. There is a set of 10 DIP switches on the back right as you face the unit. They should be set as follows
1. Off
2. Off
3. Off
4. On
5. On
6. Off
7. Off
8. Off
9. Off
10.Off

The critical one to keep intermittant issues from creeping up is SW3, T1 clock source. If you have this turned on, then the Channel Bank is providing the clock, off and the clock, or T1 timing sync is coming from XO. You may not have any issues right now, but once you start placing or receiving 24 calls at a time, it tends to start giving you funky problems that are hard to track down, so just set it right up front.

Second, if XO has configured the T1 with DID's on top of the main trunking BTN, then the 4 digits you are hearing are from them, and they are routing translations for the DID's. In a PBX environment, it would tell the PBX which extension to send the Direct Inward Dial call to. Just call XO and tell them that you do not need the DID's and have them disabled, these tones will go away. The only time you would need the DID's is if you are publishing multiple numbers for your 'IVR like' system. For instance... 555-1111 is for customer service and gets one greeting or message.. 555-1112 is for Tech support and gets routed to a different, specific modem and gets a different message. If, and this is my assumption, you just publish one number, the main T1 BTN, and you don't care which channel they come in on, they all go into your software and get the same initial greeting or message, then have them disable the DID's. It will simplify your life.

You are right about rushing the job a bit. When a carrier installs a T1 circuit, there are three steps. The T1 is physically connected, usually by the LEC to a smart jack, which you have plugged into your T1 interface on the CAC. Then the 'turn up' the T1, meaning they turn on their equipment and you get a Sync with your equipment.. they can 'see' you and you can 'see' them. At this point, you can usually break dial tone and make outbound calls... even ANI the number because it is still within XO's network. The last step is to PORT the T1. This is when XO goes out to the mysterious database in the sky and tells the world that your phone numbers should find their way to your channel bank. This is the piece you were missing at first, but seems like you have crossed that hurdle.

Good luck! I will PM that manual over.
