The SE700A's are still available...
Replacing or installing a new housing is one way to help to clean up the installation if a jack can't be used.

Ed -
Are you using them as amphenol covers or for some other function?
Years ago we used them as external mounting boxes for things like buzzers. On Tele Resources 32 systems we used to drill them out and mount Sonalerts (for external bells in them).
Wait! The sonalerts went in the larger size (for 50 pair cables) SE750A, maybe?

Both, Sam. Nowadays, I insist upon using them when using a 259A adapter. We have a lot of government and medical accounts that still have 25 pr. cables for ISDN sets.
I wish I could still get the Harris/Dracon ones. They look so much cleaner and professional to me. I only have about ten of those left and I won't part with them unless absolutely necessary.
I've also used a pair of them back-to-back on a wall to get to an electrical outlet when there isn't one where the system is installed. :shhh: , don't tell anyone that I ever did that.

Can anyone post pictures of a partial 25 pair termination on a 66 block with cleaned up extra pairs so I can have a visual reference? Namely what Sam is talking about. Just trying to wrap this n00b head around what I should do to be "future-tech-friendly".
Sam to answer some of your questions: KSU/Partner will replace the 1A2 in Pic A above. So the cross-connect that's already wired to the 66 will be reterminated like you suggest on a new 66 at the KSU.
I figure at some of the station ends that haven't been hacked (most have intact amphenols connected to the existing system phones), I will just use the amphenol/modular 153 adapter. It seems cleaner to me than cutting and wiring to a biscuit... Less mess less fuss and quite simply uses 1/26, 2/27. I already bought jacks and 153 adapters to cover the entire job, so I can mix and match as needed. Of course I have no amphenols at the system end, so it's just raw wire there termed to the existing 66 in Pic B. Is there some sort of disadvantage to using the adapters?

No, not at all other than aesthetics as mentioned.
You need a certain number of posts (I forgot how many) before you can have an avatar.

Interesting, Hal. The stripes on the wire are different than a standard 25 pair cable.

Jeff:
Western Electric used "band marking", like what you see today where a base color just has a colored band around it every inch or so. Chances were that if you saw a key system installed in the sixties with band-marked pairs and gray cable jackets, it was Western Electric, hence a Bell job.
General Telephone's cable manufacturing arm (General cable) did the longitudinal stripe. GTE also used the "purplish-beige" jacket on the large cables. Later on, they lightened the hue of the beige jacket, but still kept the same striping.
Prior to that, in the early days of plastic insulation, the pairs were in solid colors for both companies. Today, it's anybody's game, so things aren't as cut and dried as they used to be. And here ends your telephone history lesson for today.

waldrondigital, If you still feel apprehensive about this install, I'll donate my services just for the love of 91 year old grandmoms everywhere. I'm located in the IE, so it's a decent hike, but we can work it out!
