My list of touch tone dials, and wiring

[Key2871]

The following are three pages of wiring information on touch tone dials I have encountered in my tech day's.
Any questions, I'll do my best to answer. But these were published in an ATCA newsletter years back.

Dear Key2871:

Hello, can you email me a copy of the three pages of diagrams, please?

I have part of the list of tone dials, but have lost some pages since I first downloaded and printed them.

My email is eburnett1963@gmail.com. Thank you.

Dear Key2871:

Also, when I originally downloaded the pages, there was also screw size info. with them.

Screw size? All I had was the wiring of the dials then some notes on network connections. I'll try to scan them and send them to you.

I know that they came out kind-of  dark, but even with flash that's the best I could do.

[RotoTech99]

OK, Thank you. I can probably use my Irfanview program to edit the pages darkness & make them more readable.

ISTR Someone had a list of tone dials and screw sizes that someone had posted on one of the sites that looks very similar to yours, except there wasn't spacing between the listed dials info. on the pages.

I thought maybe it was yours; it has a what looks to be a web address on the bottom left corner, but I didnt see a mention of who created it.

I'll look for my copies, and send you what it says on the bottom left corner. I have to look for it, but I can do that in about 30 min. I think.

Dear Key 2871:

OK,  I found the pages i mentioned... Its dated 6/9/2010 titled screws and touchtone pads.

On the bottom left corner of each page it says mhtml://e:\Screws.mht

It also says touchtone diagrams by Ken Chase.

Presently, I have 3 of the 4 pages.

Hope this helps with my request.

ITT 32 G dial.

Orange & Black- C on network.
Black.                - RR on network.
Green.               - F on network.
Red & Green.   - R on network.
White.               - E1 on network.

Red.                  - E 2 on network.
Blue                  - B on network.
* Brown hook switch lead to term on back of dial.

Now for those who are not familiar with network's and connections T & S terminals are found on western network's and simply tie points to connect with handset leads.
I didn't put what also goes on E terminals with dial connections because you should see a pattern on what goes where with what handset lead.
I banged this information in on my computer last night, twice. Got all done, and the computer burped and all data was gone. I gave up. Now I'm doing it on my phone.

ITT 4600 OPG, OPD, OPA dials 


Orange & Black- C on network.
Green& White.  - C on network.
Red & Green.    - R on network.
Blue.                   - GN on network.
Black.                 - RR on network.
White.                - E1 on network w / White handset lead.
Green.               - F on network.
Red.                   - E2 on network w/ Red handset.
Orange.             - insulate and store.
Slate.                 - insulate and store.

ITT 42 EPG dial

Orange & black - C on network.
Red & Green.     - R on network.
Black                  - RR on network.
Blue.                   - GN on network.
White                  - E1 on network w/ White handset.
Red.                    -E2 on network w/ Red handset.
Terminal on back - Brown hook switch lead.

AT&T 72H3A dial

Orange & Black - C on network.
Black                  - RR on network.
Red & Green.     - R on network.
Blue.                   - B on network.
Green.                - F on network.
White & Blue.    - T on network w / White handset.
Red.                   - S on network w/ Red handset.
Screw terminal on back - Brown hook switch lead.


Again most times black handset goes to B on network.
Dials that have terminals on the back have polarity guards built it.
It's been many years since this list was made and typos may have occurred. And since I don't have all of these dials available to me anymore. I may not be able to help you out.
Just read the list, you will see common leads to common terminals on any network. Handset leads for the most part are out lined clearly. So when you see diagram that doesn't specify, try handset leads to common points.

[Key2871]

I never did a page on screws, sizes or anything like that.
On page three it mentioned a screw terminal on the back of the AT&T dial, for their polarity guard.
Any questions, let me know.

Thanks, Ken

Another thing.
Network's power on when tip & ring are applied to terminals
RR and C. RR being tip. E terminals are the same as T or S terminals on the network. These have no electrical connection to network circuitry. These are simple connection points that are isolated from network circuits.
As are terminals F, L1,L2. Are terminals providing connection with hook switches, and F is used in rotary dials, with dial leads breaking terminals RR and F for dial pulsing.

Dear Key2871:

Sorry to hear about the computer burpup you had...

I can copy the wiring down by hand, as oddly enough, I'm using my mobile phone at present while my computer is on the blink.

When I get on a regular computer, I'll see if I can copy those off, either to a thumb drive, or print them off.

As to lightening them up a bit, I'll have to check the file extension suffix, but if its one Irfanview will handle, editing them should be easy.

I may also have some dials you can add to you can add to your list; I'll have to look them up, but I can send you a list of them with their wiring.

Thanks,
Rototech99

Dear Key2871:

Hi, I checked the file format extension on the pictures of your dial wiring pages... Since they are .jpg format, my Irfanview program will handle that easily.

I'll look around a bit, and see if I stumbled across where I first saw them, and let u know.

Thanks,
Rototech99

Dear Key2871:

I found the website where I originally found the diagrams I've asked you about; they are on the oldphoneman.com website.

If you check there, you'll find the page I mentioned saying "screws and touch tone dials" at the top.

Ah, OK I remember him from the ATCA. It's been so long I forgot about his site. He most likely copied it from the news letter I posted that list in.
I hand typed the information here today, so anyone who wants to copy, print etc do it with my blessing.
You could copy the information on a thumb drive and then print it off for future reference. I didn't know that taking pictures of the pages would come out so dark.

Another thing to remember is a lot of those dials were found only on multi-line telephones, or key phones. And I posted that way before the internet had this information available.
Doing the proper search will most likely get you more detailed information than what I put down.
