This is a COCOT desktop payphone designed for placement on a store, bar, or restaurant front desk. COCOT is a short form for "Customer Owned, Coin Operated Telephone". It does not require a payphone line from the telco, and doesn't require operator interaction to determine rates. To do this the phone has an updateble rate table on board (SRAM). When a call is made, the on-board computer looks up the rate from these tables. Voice and operating data are recalled from ROM on board.
When a call is answered, you signal the phone to start charging by depressing a button. Until the button is pressed, you can hear the called party - you can't talk to them. If the button isn't depressed, the call is cut and coinage returned.
1) Dial Desired Number
2) Deposit Coins Per Voice Instructions
3) Press Talk Button When Party Answers
4) Deposit More Coins To Continue When Voice Instruction Is Heard.
Rather than a digital display, this early COCOT uses a voice announcement to tell the customer how much to deposit.
Does anyone have access to an owner's manual for one of these, or better yet, a programming manual? This phone was given to me, and I would like to set the rates so that it can make calls from our area without its seeing it as a long distance call.
