The MDF was on the 4TH floor with phone system. A 110 had 24 pairs running to the basement to another 110. I punch down and connect the phone system By rj 45 at the phone system. I toned it at the basement but only 1 pair was ringing. My main concern was 1,2,4,5. I connect my cable tester but only 1 pair shows continuity 1&2. Did I screw up or is the 24 pair crossed? It's haunting me.
Did you tone out the pairs you were going to use before you punched them down? That's your first step, doing anything else before you verify you have good pairs is a waste of time.
How are you going from the SmartJack to the 110 block and the 110 block to the T1 jack on the phone system?
Like has been said earlier. Need much more information.
