OK, each tenant will install their own small phone system utilizing a professional installer (not me). I am simply doing the hard wiring for the units for the phone and the data and want an interface that any telephone installer would be pleased to work with. The patch panel is an easy decision for the data lines however, I also have to terminate all of the phone drops at the closet somehow (patch panel/66 block/110 etc. Just looking for some advice on how to terminate the phone drops in the closet. Each unit only has one Cat5e incoming from the telephone company so under this scenario it is a maximum of 4 POTS lines. They may only need two, it doesn't really matter to me, I'm just wanting to terminate the phone drops at the closet somehow and make an easy interface for the drops with the incoming telecom line(s)??? The actual phone system will be up to the tenant and their installer.
