Connecting FXS Interfaces using Centronics Cable

You can purchase AudioCodes' Centronics-type cable connector, as shown in the following figure, to connect the FXS interfaces to FXS equipment. The 10-meter cable (32.8 ft.) provides a 50-pin male Telco connector on one end and open leads on the other end, which need to be connected to your patch panel or distribution frame.
