Ingenico ICT220, and ICT250 terminals use a "Magic Box" to connect the phone line, ethernet, and power to the terminal itself. The Magic Box coiled cable has length of 3 feet.
Our original Combox was damaged wasn't sure where to get a replacement. These guys were recommended to me by a friend. I placed the order online, and the replacement unit was the same as the original one that came with the terminal. Replaced with with this new box and everything worked great.
