One of our viewers assembled an “ISP in a box” setup with some more features than our original post.
This setup has 4x FXS ports to provide analog dialtone, channelized T1 cards, and Cisco Digital Modem modules (like those in the AS5x00 series). Dialing 5551212 from an analog line will connect you to the modem bank where you should be able to achieve a 56k connection. You can also dial between the ports on the 555000N numbers.
This complete hardware setup is currently listed on ebay: https://www.ebay.com/itm/305790619218
