I recently purchased a fax/phone/modem switch that claims to do just that. I don't know how well this works, because I don't have distinctive ringing. The brand name of the fax/phone switch is "ExtraLine" and it cost me about $150+tax. It is supposed to be able to select one of two devices based on distinctive ringing.

Do they answer to the phone line, and then decide based on the tones what type of call is it? And then, do they simulate the calling tone to the fax and the modem? If so, aren't this tones diferent from country to country? In short, suppose that I have a dumb fax and a dumb modem, can I interface one of this devices between one phone line and them?

Do they answer I bought a model called the Eliminator TF 300 at Office Club a couple of weeks ago. The instructions say that it looks for "audible beep tones called CNG (CalliNG) signals from the remote fax. After a brief timeout is seems to switch to the voice circuits where my modem is stimulated by Eliminator produced rings. It mostly works OK. Every so often I'll get someone out there sending me a fax with a modem that doesn't produce this signal and the fax gets connected to the modem.

No, the beauty of it is that they don't have to answer the phone, because they can tell from DISTINCTIVE RINGING what device the call is for. So I have the telco assign 555-0001 to my voice calls, 555-0002 for my modem calls, and 555-0003 for my fax calls. The telco sets it up so that all calls coming into my line when 0001 is dialed result in normal ringing cadence, 0002 causes a double ring, and 0003 causes a triple ring. The fax/phone/modem switch will divide the call among one of three outgoing RJ11 jacks according to the ringing cadence. In the example above, the numbers don't have to be consecutive. The telco just assigns three different telephone numbers to one line, and each one causes a different style (rhythm) ringing. > In short, suppose that I have a dumb fax and a dumb modem, can I > interface one of this devices between one phone line and them? Yes ... assuming that your telco offers DISTINCTIVE RINGING as a feature. One manufacturer of these devices is ITS Communications of Endicott, NY. They make the AutoLine Plus.
