The extension module for the Snom D3xx series

The Snom D3 is the optimal expansion module for the Snom D3xx series desk phones with USB connection.

The expansion module allows users who make a lot of calls greater flexibility and productivity by providing 18 programmable LED function keys with features such as line hold, speed dial, extension and presence indication.

The Snom D3 with its high-resolution black-and-white display can be easily connected via plug-and-play using a USB cable. Up to three extension modules can be connected in series to expand the range of functions enormously. This provides up to 54 additional function keys.

Notes:

• Please note that from the second connected D3 onwards, this must be supplied with power using an additional Snom power supply unit. This will then power the second and, if desired, the third D3 in the series.
• As each D3 has a USB port, other devices such as a USB headset can be connected to the last connected D3 in the series.
