Cross Over Cable For Some Model of Headset

If you want to use headset products with an RJ22 plug, a special cable (known as cross-over cable) or a cable adapter box is required. The standard handset cable (supplied with the headset) is a roll-over ca- ble standard for ALL handsets using RJ22 plug.

The default handset plug PIN lay out is China standard (Made in China). US and European customers cannot use local popular RJ22 headsets without adjusting the connection wiring as follows:
