Hi guys....we tried several times to drill out RJ45 plugs for the ML and PL...with not much luck...so.what we did was the following..

 We have 5 link rooms and we ran CAT6 STP in the walls....and terminated with female DB9 connectors and then cut ML and PL cables in half and made DB9male to PL and ML (from the wall)...

 DB9 is available all over the world, as are the wall plates, etc....so i'll take pics once the install is done..

Just wanted to give a different angle on the CAT6 in the wall ideas..
