"Turret? Multi key service apparatus. "

"Turret? there is no such term."


OOOOOOOOOOOkay.

Am I missing something? I worked on plenty of them in the 1980's for a large service bureau. Turrets really didn't exist?

I never heard of using a T1 on 1A2 to concentrate line appearances. Please tell me more about this concept. You can never stop learning new tricks.

?????

Wait till you have to replace the light bulbs under the keys. Heh heh heh

Ed -

I worked with a couple of Channel Banks that offered the opportunity to send "dry" pairs over T-1. I assume you could use these dry pairs for A & L leads. I was jesting of course when I suggested this, but it is at least theoretically possible.

Sam

Thanks a lot, Sam. That's not exactly where I was heading . Matt's pretty serious about making this system install happen, so I would not be surprised to see a channel bank sitting on top of his refrigerator! If so, we'll just blame it on someone else.

Actually, I could put it in my fridge, if it needs the cooling.

One thing's for sure... as a single guy, the only other thing you might find in my fridge is a 6 month old 1/2 gallon of milk, some orange juice about the same vintage, and some Dr. Pepper.

Used to be a good place to keep beer, but after years and years of pretty heavy drinking, one day I just couldn't drink any more. One beer = headache.

So I'm all for turning my fridge into a line concentrator.

I got all the cross connects redone, will post pics soon. I went ahead and wired all 4 lines + intercom, but I've some troubleshooting to do. Line lamps on some sets work, but not on others. Will be easy to track down, but I'm cooked.

Oh, and I'll get the info on the 3 pair to the kitchen tommorrow.

Thanks all -
Matt

LOL that is too funny!

Yeah - but it's true!

I'll post pics soon, but just wanted to say thanks to Arthur for pointing out my cross connect wiring error. I got done repunching it last night, and even though I only have 2 lines, I figured I'd punch all 4 and obviously the intercom.

Line positions 3 and 4 lit on some phones, not on others.

Because of the cross connects... it was a simple matter to see what was going where, and although I was tempted to break out a butt set and listen to see if I could hear 10 volts, I opted to use my high tech, fancy dancy, new fangled VOM.... easy process of elimination, had the problems repaired in about 10 minutes. Lesson learned: If you pull a lead from a terminal, make sure the terminal is completely free of old wire/insulation. Sounds obvious, I know, and I looked them over before repunching... but I missed a couple terminals.

Also the tip about keeping the cross connects loose came in handy; just gently pulled on the lead to see where it was going - so thanks to Sam et. al. for that.

More thanks to come. All you guys are fantastic.

And apologies to Ken, he taught me how to do cross connects when he was here, but I apparently forgot.

Waiting for the pics
One mistake I have made is accidentally skipping pairs or punching two wires on the same pin. Makes it hard for things to work!
