D7 Expansion Module

Powerful, high-resolution, and easy-to-use expansion module

An expansion module provides users who need to make a lot of calls with greater flexibility and productivity. The D7 expansion module enhances the D7xx series by offering 18 programmable LED keys with functions such as line, speed dial, extension, and presence indication. The D7 expansion module is available in black and white.

The high-resolution display serves as a perfect visual interface. The D7 can be easily connected via a USB cable. Up to three expansion modules can be cascaded, providing up to 54 additional function keys. The last D7 in the series includes a USB port to which other devices, such as a USB headset, can be connected. When two or more D7 units are used with a phone, power is supplied through an additional external source.
