- As I understand the FCC regs, you can connect anything you want to the
- telco system as long as it connects thru an approved interface. The
- idea is to protect the telco equipment. Build anything, a modem or
- answering machine or better mousetrap or whatever, no approval needed
- for anything except the bit that touches the pair of copper wires from
- Ma Bell. I understand that interfaces are easily purchased.
