External (adjunct) Touch Tone dial project

[Vacuumlad1650]

Is it possible to connect an external WE touch tone dial to a 500 set and have both it, and the rotary dial connected?

[Key2871]

I don't see why not. The rotary maintains connection, the tones just go to the Co to process. What dial are you planning on using?

Absolutely.  Western Electric created "adjunct" dials for that very purpose.

You can read about them in the following BSP in the TCI Library:

   501-164-130 i8 Oct75 - Station Dials, 1035- and F56309-types - 12-button adjunct

   http://www.telephonecollectors.info/index.php/browse/bsp-bell-system-practices-by-doc/bsp-categories-by-later-division-number-by-doc/500-529-station-equipment/501-division-station-set-components/2697-501-164-130-i8-oct75-station-dials-1035-and-f56309-types-12-button-adjunct/file

The BSP includes wiring diagrams to connect adjuncts to many models of WE phones.

Thanks, John! While you were adding the above, I found these:

Im having a hard time inderstanding how to do this. Is it possible to use this dial?

I would probably use the above suggested method of a duplex jack as not to alter the telephone in any way.

I posted several wiring diagrams on touch tone dials, recently.
Look under touch tone dials and you should find what you need to know. What's dial is it your using, looks like a western, but what's the number on the dial?
35AH ..?

[compubit]

It looks like 35A3A

I'm using a cell phone, so I can't really cut and paste a link.
But it's here under tech stuff, look for touch tone dials wiring.
It should give you information on how to wire your dial up.

Thanks PAUL.

What I'm wondering is what wire to I connect the capacitor to, and what terminals do I connect the two feed wires to? I have a duplex jack to use to connect it in-line as not to alter the telephone.

[Key2871]

The capacitor is for the ringer. It is not connected to any part of the tone dial circuit.
YOU are talking about A and K on the network, right?

[Vacuumlad1650]

Found this in the instructions...

[Key2871]

I don't know what instructions you are referring to, I'm trying to read and figure out what it's talking about.
If you're using an external dial on an antique phone. Then I wouldn't have any idea where to make connections.
I thought you were using a 500 set and a tone dial on that.

The instructions posted above as an image came from the ATCA article posted

    https://atcaonline.com/ttpad.html    ( dead link 6/13/22 )

by Stan S. about 6 years ago (which included instructions and a complete list of materials needed) was added to this topic by paul-f in reply #2 above (2nd of 3 links posted)

    http://www.classicrotaryphones.com/forum/index.php?topic=20558.msg210181#msg210181

and was "simplified" by stub in 2012 by showing how to use an external modular jack to make the external dial pad useful and universal to any phone (without rewiring the stick, 302, 500 etc.) in the 3rd link offered above in reply #2 by paul-f.

It is very important, essential, to read the complete topic from first to last post and look at the links offered prior to posting help replies in order to keep replies from being nothing more than opinion based on thoughts from the very last (previous) post. Posting an uninformed reply that doesn't do anything more than confuse the topic shows the person writing the reply did not read, is not familiar with everything posted to that point and exposes that member's lack of understanding of the help request making the uninformed reply nothing more than opinion based on false assumptions.

The last question asked by the member was "where to attach the two wires from the adjunct dial pad to the 500" and that was given in several earlier replies. The member trying to attach the adjunct DTMF dial to a rotary 500 is having difficulty with understanding the linked information and is doing nothing more than asking for and only needs straight forward help (wire 1 goes to terminal X and wire 2 goes to terminal 2). Guesses made to a false assumption based on failure to read, to have full understanding of the topic, does not progress the topic to a successful conclusion. For example, this diagram



from this topic

easily found using the forum "Search" function and something bigger than a smart phone.

This forum and its "request for help by members" topics relies on informed, accurate and correct replies to the request to resolve the problem, to move the topic forward, to provide the help and bring an end to the topic in a way that will help other members, years from now, by providing clear, straightforward help, basically by reading good instructions and not misleading tangents. Posting something other than help based on facts does not help anyone.

The original question asked how to attach a DTMF dial to a 500, or other phone, a question that had been asked and answered some 6 years ago, was moved forward by members providing links to those old topics that showed how to do it. If the member is having a difficult time understanding the old instructional posts, questions are appropriate and direct answers to those questions are all that is required to help the member complete his project and end this topic.

Having an understanding of the complete topic, taking time to read/know (to study) what is in the topic prior to posting a reply is essential to providing quick and correct detailed help to the member asking the question. There is no reason to post anything that confuses a topic making it almost unreadable to future new members trying to do the same thing.

The above posted diagram seems to help my understanding. Thank you moderator (can not remember your name off the top of my head). I need to order a resistor, then I am going to be testing this out. Line in-> Red/Green. Connect one end of the resistor there. Connect other end to Blue, and jumper to Orange black. Line in to telephone from there. Line out as normal.
