GN 1200 Smart Cord The GN 1200 connection cable is the solution to a general problem of connecting a headset to the telephone. Although most things have been standardized, the cord that connects the phone to the handset or headset is anything but standard, as each phone manufacturer has its own wiring code. With the GN 1200 Smart Cord you can now set all the assignments for the different telephone sets from the individual manufacturers using a switch on the cable. It is available in 2 different versions. A smooth cable with approx. 80 cm and coiled with approx. 70 cm can be extended up to 2 meters.
