since your never going to need the connector on the end of the 25 pair again I would just cut them off, and use a $2.00 flush mount jack rather than the $12 adapter .

Save some money and have a better looking install

The SE153-AM-01 is just going to pick up the w/bl and w/or pairs off the cable wherever you use them. Your choice- use them at every location and and pull everything except the feed off the block in the can and and just re-use the w/bl and w/or from each cable. Cut them down on the opposite side of the block from the feed. Provide another block at the other end of the feed by your KSU and cross connect.

If it were me I would probably just put a biscuit jack at each location and be done with it.

Here are the "before" pics of the job and what I'm working with:

Picture A (Basement):
I have no idea what you call this old patch panel, but it will be replaced with a single 66 block with a 25 pair cross-connect back to the Partner.



Picture B (Basement/20 feet away):
This is the old 1A2. I intend to reuse the backboard and pull off the dialers and jacks left behind on the left hand side of the board. In its place will be (2) 66 Blks and the Partner.



What a mess...

Picture "A" is not a patch panel. It's a 66QAB 50 pair X-Connect terminal.

Personally, I'd rip that out as well and redo each cable on it's own 66 block (BIX would be even better). Sorry, had to get my shot in there.

Picture "B" is as stated a mess, but you should have no problem cleaning that part up either.

Why? Looks perfectly good to me. It's not a "patch panel" and those are 66 blocks. Just rewire, get rid of one. It's nice to have that can.

Hal,

Do you really think I should reuse something that is 40+ years old? I figured since I have to do this, I might as well go all the way and just replace everything but the wire itself. No?

Re; Pic A - Keep in mind that each of those 25 pair cables (except for the cross-connect back to the 1A2) is going to ONE STATION per cable. I planned on just trimming all but the two pairs I need and consolidating on a single 66 Block (has enough room for the needs of this job).

I always try to keep it as simple as possible... an old IT habit I suppose.

Correction: I incorrectly stated that "block" was a patch. Whoops. My bad.

Trim back the unused pairs, yes. Please don't completely cut them off. You may need them in the future. Just pull them loose, straighten them out, tape the ends and keep them stored neatly within the terminal.

Good point Ed... although my Grandmother will be long gone by the time we will need any other pairs. But you're 100% right... I'll just tape 'em up. And when you say "keep them stored neatly in the terminal"... what do you mean? Tuck them behind the 66? Sorry that's a very n00b/sparkie question, but I have to ask.

Good telephone tech Karma I suppose... I can just see some tech coming in there in 10 years and saying "Thank god the guy who did this left the other pairs!!" LOL... Have I mentioned this house is about 100 years old?

This old phone guy would use spit blocks and punch em down, on a backboard of course. Sure you can just hide them behind the blocks, but it'd look a whole lot better and if you every wanted to run another pair you'd just run a jumper. No muss no fuss.
