Coin line controller
« on: December 09, 2014, 04:53:05 PM »
Would it be possible to build a micr processor controlled simulator for a coin line payphone? I mean  to do what the CO would have done? I imagine it would be costly.  Or should one just live with a COCOT board?

There are circuits available that do it with some transistors, a couple of relays and and a handful of resistors and capacitors.  However, you need to start with a complete payphone that includes the coin relay. 
 
Some circuits are simple and simply always collect or refund the coin when the phone is hung up.  Others contain a timing circuit that simulate the action, and will collect a coin if the duration of the call is greater than about 20 seconds or return the coin if under that time.  The reason for the timing circuit and the simulation is because these days there is no supervisory signal on a regular phone line that signals when the called party has answered.   Pay phones used to be connected to a special pay phone line at the central office that was made especially for pay phones.  These days we can only simulate.

Why not use an analogue telephone adapter that has either polarity reversal on answer or metering pulse generation to provide answer detection?  Also if you have a postpay phone all it needs is polarity reversal on answer, ie it dose not need the ability to collect or return coins.

Also many phone companies (at least in the USA) still provide "coin lines" for dumb pay phones although that can be somewhat expensive, and i'm not sure if they would provide it to a residential customer

It is not easy to get the signal telling the controller what to do, and when. It is some on the market, controlled by timers, sometimes by line reversal etc.  My home-made unit detects polarity reversal from the ATA, and collects or return on hangup depending on callee did answer or not. Still, I have no time limit, and you may call any number not blocked by my dial plan on the PAP2T. (I have put up a maximum call timer at the Callcentric account) 

For North America I just have used this dial plan: All numbers are dialed 1+10 digits, and I believe this setup excludes the expensive numbers.

Maybe he should double his line and come up with a reliable pulse to tone converter.  Shouldn't be too hard for him, I wouldn't think.

JohnnyJT ,

I agree with you. I have bought two of Stan's controllers for my Western Electric 236G's within the past few months. They work great, are easy to hook up and Stan is fantastic to deal with. I leave mine plugged in all the time and they work like a charm. I definitely will be purchasing more from Stan in the near future.

Looks like a payphone controller was actually made for use by psp's I assume this is what you mean by omniphone payphone controller?  The question is where would you acquire one

I have some new old stock,I have them stored, I need to break one out and see if they fire up in some kind of default mode. I also need to look around for the software. I know some foks that used to run these things. They were really cool they could be used on a rotary or TT payphone,they read coin tones and did the whole reverse battery thing. They worked just like a Bell CO coin trunk. They could also be programmed to provide service for a charge-A-call and take credit cards. I was able upon closing out of CBT's payphone department to buy up a lot of there remaining payphone stuff. I have it stored in shipping containers. The phone company I own still provides payphone service but the core phone business is inmate phones. I run protel payphones now. W/E type and GTE type. Protel 8000,7000,310 And 2000. I also managed to acquire protel Acension.

Extremely interesting, I would like one too.
I guess I already are the only one i the entire Norway who has an AE 120B  payphone who collects money the right way, but only once, If this will work it may collect  more on longer calls.  ;D

It requires software and rate file.
