The Snom D7 expansion module adds 18 programmable keys with LEDs to the 700 series, providing features including line, speed dial, busy lamp field, and presence indication. A visual interface is provided through the high-resolution monitor. The D7 uses a USB cable to connect to the phone, and up to three extension modules can be daisy-chained together to provide 54 function keys. Users with excellent call coverage might benefit from an expansion module, which gives them more freedom and productivity. The D7 at the end of the chain has a USB connector for connecting extra peripherals like a USB headset. Additional external power is required when more than one D7 is used with a telephone. With 18 LED keys, the Snom D7 is a highly programmable extension module. Up to 54 extra keys can be added by daisy-chaining the D7 Expansion Module.
