| Channel Banks and 66 Blocks |
| Ok I am installing cable/internet/phone in a new building and we are doing phone lines punched down to a 66 block then Amphenol cable to a Channel bank. The problem I need help with is what to do with the 25 pair on the 66 block and Amphenol when the channel banks only handle 24? Is that just industry standard that it is not used? If it is used what is it used for since the Channel bank only handles 24 do i need a whole new channel bank to handle that 25 pair? |

Dear Vuc,
Not to worry: the 25th pair is usually simply disconnected on both ends. If you feel like you want to do something good about it, you can ground it if there is a grounding clamp nearby. Just extend a pair of AWG24 wire between the 25th pair of 66 block and the clamp. But usually people just left it disconnected.
Sincerely,
Dmitri Abaimov, RCDD
