Good Afternoon,

I have a project I have been working on for some time and need some assistance. I recently obtained a Carrier Access Channel Bank I. Likewise, I got T1 service for it as well. The trick here is that I need to connect the channel bank to an IVR server I have. The IVR server is strictly analog and consists of 24 ports. From what I understand about channel banks, they convert T1 lines to 24 usable analog lines. This is precisely what I need to accomplish. I need to access each line through the bank and plug it in to my analog devices. I also have a modular punchdown block that really doesn't need to be punched down. It's sort of plug and play. I have the link to it here. https://www.telephonestuff.com/cata...D1A4B91E942CF75B385FC42D01F&pid=3464 So I guess what my question is, is any of this possible using the equipment I have? Am I going about this the right way?

Any telecom help or advice would be greatly appreciated
Thank You

That Siemon block will work for connecting the analog lines from the carrier access output to your IVR if they have single port modular input to the IVR . What was the other question ? Thanks

Oh by the way , will you complete your profile . It helps us to know who we are helping ! Thanks Alot .

Thank you for you super fast reply. I would like to point out that I do not have a KSU or PBX to plug the channel bank into. I am running it stanalone. So I guess my other question is, how do I configure the channel bank. Currently, I have had very little success. I call the numbers the telco provided to me and I get busy signals. I have not yet performed a successful call. I am actively toying with the bank settings. Actually there are tiny switches. Many switches for that matter. Additionally, all LED lights are solid green. The STATUS light flashes green. I really don't know what it all means.

Just as before, any help or advice would be greaty appreciated.
Thank you again

How ‘bout a lil’ more info on that “Carrier Access Channel Bank” you mentioned… I’d bet there are more variations of chan banks out there then switch you have to fiddle with on it.

Do you know how your T1 Provider is handing off the circuit . Is it ESF B8ZS or D4 AMI ? Also do you have a manual for the Carrier Access unit ?

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

I'm checking with the provider now. I am not sure how the circuit is being handed off. Which should I prefer?

You know, I had a manual for this device. Now that I need it I can't find it. Isn't that typical?

Since you're not carrying data on the channels format and coding does not matter … it JUST HAS TO MATCH AT BOTH ENDS!
