I am not sure of your budget but I would go with a SIP to FXS gateway such as the Quintum Tenor AX. If you consider the amount you would be paying for the T1 card and the Adits, it may not be that big of a difference and certainly more simple. Disclaimer, I have not done a price comparison or done the channel bank solution on that scale (only 24 ports for me) but the SIP-FXS is so much better in my opinion.
