I bought a Payphone case that was striped of the program board and related items.

Anybody know how to get the keypad to work with a standard Western Electric module or “guts”. It’s actually an Elcotel and the Keypad and Hook Switch mounting has 61C coin dial printed on it, with the standard round eleven-pin plug.

I am sure I can get the standard gray plastic keypad to fit, but I would prefer to use the chrome keypad if possible.
I’ve tried wiring it many ways with no luck. I get touch tones, but no dial tone.
I tried a different Taiwan unit and I can get dial tone, but no touch-tone. I would kind of like to have both.

The keypad gets plugged into a Elcotel board. The line powers the board and dial tone is heard and the dial can dial. If you need a board I have some.

By the way, you will also need a battery for the board.

Yeah, I know thank you, I am trying to do it on the cheap. I only paid 30 bucks for the phone, and I don't want to pay another 100 for a board, but I will keep that in mind.
I have an Intellicall Payphone that is complete, I paid 30 bucks for as well. That one has to be programmed for 25 bucks. (Or not if I don't feel like it.) These phones have no real historical value, so I'm not to worried about authenticity.
What I really want is a Western Electric Dial Payphone. (Of course)
I have a couple of interesting links for Bell System public services manuals (Payphone) that I already posted in another thread. These are fun, but of course kind of long winded.

I forgot to list the link for the page those other links are listed on. More telephone manuals than you could ever want.

How about retrofitting it with a Western Electric Chassis 32C board? It uses the same 61C coin dial, which I have. (It looks like I can get a 32C board fairly inexpensive.)
I'm not sure about using the same coin shoot and relay.
I would prefer to have a proper Payphone rather than a cyborg.

You can make it work using a standard 32C, but it will not accept/reject coins because this functionality requires a true coin phone ground start line. Coins deposited will just pile up in the escrow chamber until it eventually becomes clogged. You can gently press the armature of the coin relay in by hand periodically to dump the coins into the coin return, but there's no easy way to make this happen otherwise.

It will however function as a regular phone with no coin deposit required in order to make or receive a call.

Thank you

EBay has the Elcotel TSG Pay Phone Chassis Assy# 44119-200-03B, which looks like the original part from this case.
New for 17.00 plus shipping. For a hobby project, this looks like the best option.
Now that I have the bug, I might have to hook up the other complete Intellicall I got at the same time.

I'm pretty sure you'll need the programming unit for the Elcotel board. You'll also need to make sure that the coin relay coil is low-voltage (typically 24 or 32 volts). There should be a sticker on the windings that indicates the coil voltage. If it is unmarked, then it is probably the standard 130 volt coil.

Whoops, my mistake, the back and bottom of the phone are out in my shop were it is cold and cluttered. (Well I did just get my socks wet in the rain when I went out to get the correct info.)
Anyway I was mixing the Elcotel with the Intellicall

The one I’m working on now is

ElCotel 1D2-LCTL2-003 Coin Tel – On the Case
Dated 07-98

Sorry for the miss direction
Coin Return on Left
Chassis Board on Right (Missing in this case)
Relay – Elcotel 1A – No Voltage Markings

Anything else on this device, I’m in the dark. Any info would be appreciated.

Thank you,

Uh, standard 103 volt?
At this point I realize I've asked allot. I used to be a Cisco certified Network engineer, Network Administrator, (Or flunkey with delusions of grander.) and played with phones on the side. (3 slot pay, etc.)
When you say standard 130-volt coil, would that be Western Electric? The Intellicall that I have has a 12v relay I believe.
This one is pretty beefy though, so I wouldn't be surprised if it is 130v. Maybe the label fell off, and I should put my tongue on it. (What better way to test it)
Maybe I’ll go back to considering the WE chassis 32C board. I’d still be able to call out and receive. (And it would look good to.)

"Real" telco-grade coin telephones (WE, AE, NT) use a 130 volt coil that is powered from the central office. They use this voltage (DC) so that the phone can differentiate it from the standard ringing voltage (90-105 VAC). Since it is DC, depending upon the polarity of the 130 volt signal sent, it is able to determine whether the coin deposit should be kept or returned.

COCOTS (Customer Owned Coin Operated Telephones), such as the Elcotel use low-voltage coils since all of the logic and commands are performed by the internal electronics.

Thank you again.
I always like to know what voltage, amps (or lack of), AC, DC etc. that I’m working with.

I remember as a kid regularly being shocked when the house phone would ring while I was running wires, or fixing something. I knew then it was around 115 volts. (Making sure a line was open or disconnected didn’t use be one of my strong points.)

Well what do you know I found the cyborg answer. I was reviewing one of the first downloads I had made during this project, and there it was.

Under Network Connections Coinless.

I was so close doing the hard way this seems like cheating. (This isn’t exactly the way I wanted to do it, but I’ve spent a lot of time on this.)

Time to hook it up, and hang on the wall. I’m just going to wire the coin chute open.
(My girlfriend just rolls her eyes. She doesn’t understand why I need a 3 slot and a single slot.) Now all I have to do is build a wing on the house for all my toys.

Thanks again for all the suggestions.
