Gee, Ed, why not get up to date --- get a 701?

501 --- bigger version than the 601, smaller than a 512. Don't you just love the ITT numbering?

401 --- electronic (Aries)
501 --- 1A2
601 --- 1A2
701 --- electronic (French import three pair)
801 --- electronic (Gee, what did they call it?)
802 --- electronic (Biggr version of 801)
512 --- 1A2

These were all considered "Key" systems although the 802 shared the 3100 PBX CPU.

You guys amaze me with your ability to remember all of this stuff. What brief time I was exposed to these systems (early 90's) I was just starting out. I was training on Norstar switches, but my boss would work on everything. He would send me out on calls to Domino's which either had a 501 or a 601 in each of them. Most of the time it was just to replace the phones. Domino's was notorious for getting the corn meal in every orfice of the phone and we would simply replace them. But occassionally something else would go bad. It was mostly the line cards, and the other part I would replace was called the interupter(is that right??).

I am glad that I had the opportunity to work with these switches. But boy I am sure glad they are gone.

At least around here anyway, I havent seen one in many years. :toast: to the guys who had to work on these day in and day out.

We had the same thing with Dominos stores around here. Flour everywhere. I don't know how it ended up INSIDE of the handset handles though. Most repairs were done with a can of compressed air.

Richard, aside from fuses, the components you replaced were about the only things that ever failed and even that was rare.

The occasional wet 25 pair connector could throw you into a tailspin though, especially when it was dry by the time you got there.

I still have training manuals out in the barn somewhere.

Rich,

Ed is so right --- flour EVERYWHERE !!!!

Used to take care of several pizza places ---- bought those plastic covers for the dial and buttons, even the Toshibas that followed --- still so much flour and grease ---

Still, 1A2 is almost bullet proof --- I thought I had cleared them out of this town until just a while back I found one I used to service in the mid-80s --- 601 still running fine, just tired sets.

See ya,

Hate to be picky, but 701 was Japanese. You are thinking of the Thomson CSF(?) system that ITT took over. Hated those systems! OPUS 20 and OPUS 40/80. ITT called the 40/80 a 56/136. They did make 1 improvement. They figured out how to put the power on 1 of the other pairs. 3pair down to 2 pair. The phones and the cards could be shuffled between systems as long as you used your head and modified wiring appropriately. They were the MOST user antagonistic system I ever dealt with!
