The provider came in an started with the repeater - then smartjack - then replaced the shelf the smartjack was in. Still failing all ones.

The tried to replace the pairs on the riser panel or house cabling on my floor (16) and couldnt run clean from any they found. We got lucky, a former tennant in this sweet installed a fiber converter at the MPOE and on 16 so we moved over to that an problem solved.

I wonder if they installed the fiber run out of necessity ?
