 Voice termination
I'm in the process of upgrading to a couple of T1 circuits. I've got the data wired the way I want (cat6). However, I am trying to figure out how to punch down on my 66 blocks without interrupting service (may not be possible under circumstances).
I've got two telco boards. One original that is patched over to a newer board. The newer board is full. I've moved our new 66 up to our network closet and am about to run 25 pair cat3 from our original demarc to this new one. Is it possible to punch down and maintain service? Or will I have to sever the circuit in order to clean out one of my old 66 blocks?
I know this is probably a loaded question, but have at it. Thanks

Dear Steve,

I would not attempt to work on the circuit alive. However, you may be able to get away by connecting the new cable at the opposite side of the 66 block and then setting the bridging clips in place when ready (if your 66 is in fact divided in halves and not all four bridged).

Even then you want to be able to call the service provider and have then reset the Ts if the equipment would fail to see the circuit. You may also have to reset the equipment, depending on your setup.

Never work on a 66 block alive just for the fact that its very design leaves all contacts exposed, which makes it very easy to short the circuit and possible damage the connected equipment.
