duplicating phone and ring voltage
I need to connect some telephone-type things together in my own little
circuit, and test them, but I don't know a simple method or what voltages to use. I think I need to use some wire, some kind of DC power, something to put a ring-signal on the line, a phone, and whatever I am testing. For example, I'm getting a replacement for my all-time favorite phone answering machine, but the owner has forgotten the 3-digit code for remote message retrieval. I'm willing to try all 900 or 1000, probably while I'm watching tv, but only if I can get it to go quickly. So I need a test line to ring it directly, have the machine answer, and punch in the code. Also I have 2 fax machines, one that sends and one that receives! I'm pretty sure I can get it down to one that does both. I don't have two phone lines, and even if I did, I think things would run quicker with my own little circuit. In the 7th grade, we had two candlestick phones and a dry cell to play with during ham radio club, and everything worked (except it didn't ring, but that was ok because they had no bells. ) Any help appreciated. |

duplicating phone and ring voltage
Phones need 48 Volts DC with an in series of 600 to 800 ohm source. The ring
is 96 Volts at 25 Hz. For the answering machine, if it is a name brand, you should be able to get the information about how to reset the remote code. If it is a fixed uninique code, then you have a problem. For what it is worth, maybe it would be better to simply get a new answering machine. -- JANA _____ "mm" wrote in message ...

My machine does not ask for any codes at the base unit for anything. The new code just replaces the old. Only remote access requires the code. But yours may be different. Kevin |

there are little circuit boxes that immitate the phone line, last I saw
one about 60 bucks |

Getting the operating voltage (48vdc) isn't that hard just hook up 4 12 volt batteries in series with an 800 ohm (If I remember correctly) reisistor on the end. Getting a 20hz ringtone is the difficult part since the wall current is 60hz.. I never figured out an easy way to make my phones ring. - Mike |

I bet we could find you one on e-Bay that doesn't entail hooking up multiple 12 volt batteries in series and punching in a possible 1,000 codes to get it to work! Do you really want to sit amongst multiple car batteries in your living room watching TV punching in codes all night and then recharging them, trying 1,000 possible codes is going to take some time and will probably require one, or more, recharges.

Hmmm, In this digital age, playing with analog? Yup... It's called POTS Plain Old Telephone Service. One thing to consider... Many fax machines and other devices have dial tone detection circuits. The mere presence of DC voltage on the line will not make them dial. Also, getting the correct 20 Hz ring frequency and voltage (with the right current) in a home grown circuit is a pain unless you are willing to get fairly elaborate. Here is a fancy Ringdown Circuit from Viking Electronics. List price is $106 http://www.vikingelectronics.com/products/pdf/dle-200b(sm).pdf Beachcomber |

Try the Viking Electronics model DLE200 telephone line simulator box.
It's only about 5" by 2 " with phone jacks on it. It only cost around $100 about 12 years ago. |

It is a fixed code. A friend of mine and I each bought one 21 years ago, and the code was printed on the box, not on the bottom of the unit that became more common. I wish it had been on the bottom; we would still have it! This new one is from the wife of a friend, and she stopped using it a couple years ago and has forgotten the code. It's Code-a-Phone, model 2530 or similar model. For what it is worth, maybe it would be better to simply get a new answering machine. Like I say, this is my all-time favorite phone machine. I have about 10 others, all different brands or models, that I've bought in the last 2 or 3 years, paying 1 to 3 dollars each at hamfests. They all work as designed but I don't like how they work. |

Indeed if you're talking about old non electronics phones with carbon mics 1.5 volts will be ok for short runs. I have always used the assumptions that there was 400 Ohms in the telephone. The telephone wants 20 milli-Amps or more so that says you need 8 Volts or more (per phone) The 48 Volts (really 52) that the central office uses is to push at least 20 milli-Amps through the longest line.

Thanks a lot to you and beachcomber. It is just what I need, and the price now ranges from 145 to 114, for the very same thing, online, plus shipping. It's small to -- oh, yeah, you said that -- and although that is a lot of money to fix these two things, it may have uses in the future. OTOH, I have the specs now to do this myself, so we'll see. |

duplicating phone and ring voltage
Hey everyone!
About the cheapest way to generate a ring-voltage problem... I've seen several "call directors", a box that picks up a ringing line, listens, determines if it's an incoming fax or modem, then sends the signal to the corresponding RJ-11 jack where the actual device is plugged in. Wouldn't one of these have to generate a ring voltage to get the fax or modem to go off-hook? Anyone have a schematic for one of these? It might be a rather simple thing to modify one of these for the OP's purpose. Comments? Stan. |

Corresponding device responds when phone rings. Even single line can have different multitple numbers, etc. Talk to Telco rep. and express your service needs. |

Of all the advice I;ve see so far, the one that makes the most sense
was the person questioning why you need to know the old remote access code to change it. The ones that I've had were set on the base unit and you could do it without knowing the old code. No way in hell I'd spend hours rigging crap to try to salvage a 20 year old answering machine when you can buy a new one for $20 |

Thanks. Good grief. 15 seconds will only let you try 480 combos in two hours. I know, and since there are only 1000 possible codes, the odds are even that I will find it by the time I'm half way through. You've never heard of Murphy's Law, I guess? I've been rather exempt from Murphy's law, except on big things. On little things like this, I actually think the "odds" are much better than even I'll find it before I'm half-way through. Jonesy |

I just don't understand why you want to spend hours and hours and hours, and some money, setting up some sort of clever, semi-automated, rube goldbergesque way to "save time" in your quest. My point is simply that you've *already* spent more time than you would have doing it the "slow" way. And you've barely begun. But it isn't like I've never wasted time, so I apologize for chastising you. Knock yourself out, enjoy it, learn from it. Good luck. |

I wish it had been on the bottom; we would still have it! This new one is from the wife of a friend, and she stopped using it a couple years ago and has forgotten the code. It's Code-a-Phone, model 2530 or similar model. Found this in google for a Code-a-Phone model 2600. "Not sure of the model number, but it sounds familiar. If it is the little black one with gold trim and the digital outgoing message, then the remote code is determinded by two things; a sticker on the bottom with a single digit (ie '7') and a switch with two numbers. ('3' or '9') The sticker determines the first digit, the switch selects the second digit. This may be true for yours, look on the bottom for a sticker with a single number; then look for the switch, it may be hidden." http://groups.google.ca/group/sci.electronics.repair/browse_frm/thread/53a6aaf7777ac05b/86ce2349e56f35b4?lnk=st&q=answering+machine+remote +control+code&rnum=4&hl=en#86ce2349e56f35b4 |

That is one of the reasons my friend doesn't use it anymore. I will look for the EEPROM. in which case you could swap the chip between the two machines. You could also read the chips using a device programmer and compare the contents, or you could simply duplicate a working chip. *simply* duplicate? I don't think I can do that. ;-) But the rest of it sounds possible. Thanks a lot. - Franc Zabkar |

I'm not questioning your desire to make the machine usable. Just your approach. Let us know how it turns out. (My email is not as shown) |
