I am looking for a device (voice channel bank) that will take a dedicated voice T1 or PRI from a long distance provider using E&M and break it down into individual voice channels (24 for T1, 23 for PRI). This device will also have analog ports that will map back to the individual channels from which a modem will be connected for both inbound and outbound traffic. The difficulty I am having is that I need a device that will take ANI from the long distance carrier, either through outband signaling from the PRI D channel or inband signaling from a T1, and send it to the analog port as caller ID where the caller ID is displayed between the first and second ring.
Please let me know if you have such a device for sale. Thanks.

Why not add some form a small PBX with PRI trunking and analog set output . You need to have a D channel to talk to the venders PRI then just pass it on to the pots ports that have clid and your set just plan T-1 will not pass the clid need the PRI.

Actually, T1 WILL pass CID on a per channel basis. We are using an Asterisk to convert a PRI to a T1 with 23 E&M lines with CID and disabled 24th line in the Mitel that is receiving the T1. Why? The Mitel is G1005 and not capable of PRI. Nor of CID without a "SPINE" bay that is just as obsolete as the G1005 and is a 48 port bay that was/is $$$$$$$$$$ to deploy. But, the Mitel IS capable of CID on a T1! It's just that most providers won't provide it!

Talking with a couple of other folks, we are sure that 1 or more manufacturer makes exactly what you want. What you want is a T1 to FXS conversion channel bank, IF your provider will put CID on each channel. Otherwise, it may need to be a PRI to FXS conversion. However, PRI tends to be unreliable for modem communication, whereas T1 is pretty darn reliable for fax and modem, in my experience. Contact Adtran for appropriate equipment and a local outlet, would be my suggestion.

You need an Atlas 550 as well as a TA750 channel bank. The Atlas will map each DID from the PRI onto a channel of another T1 that goes to the 750 to be split into FXS ports. You may also be able to get enough FXS ports stuffed into the 550 itself.

I've done this before with Asterisk and a quad-port T1 card.
T1/PRI from carrier goes in one port, T1/Pri/Whatever comes out one port to customer's PBX/etc, third port comes out and goes into a FXS/FXO channel bank.
It all works best if there is a PRI coming from the carrier as it's easy to do call routing based upon DID/CID/Etc.
