I have old board which I was trying to replace because LP51,LP52 have blown and I figured I might as well upgrade the board instead of messing about with soldering. However half-way through I noticed that the DP connection for MIC/Voice is not present on the new board (or I can't see it). The old board has a door phone module connected to a Fermax door entry system. Is there a way to connect the new board or is there something else I need to do? 
Many thanks,Tas

On CM9001, the DSI01 plug in submodule includes the Ringer, Door station Mic/Voice, and Local Telephone support circuits, see http://www.cytech.biz/product_details.php?item_id=498 which includes the DSI01 manual download.


This offloads the circuits and makes the CM9001 lower cost for those who do not need these features

Thanks, that explains the differences. How can I find my exact board model. On the DSI01 page on this forum the CM9001 board has a switch, K51, which needs to be set when installing the DSI01, however my board does not have this switch. I purchased the board just a couple of months ago. 
Many thanks,
