Bizfon 680 Expansion Cable 10-PIN Cord
The Bizfon expansion cable is a 10-pin cable, with a special pinout, used to connect a Bizfon 680 main unit to an expansion unit(s). The cable is required otherwise you will not be able to expand your system. A standard Cat5E or Cat6E Ethernet cable will not work because it's not the correct pinout.
