It's funny reading about the use of a computer to make original dial tones, back in the day, the GPO used these:

I'd love to play with one of them... ;D

That was interesting dialing all those numbers.  Really gave that 4H dial on my daily driver 302 a workout, especially since I dial out through my PBX (9) first.
The idea that a four-year degree is the only path to worthwhile knowledge is insane.

     I was able to (rotary) dial the first number, and get the '68 dialtone. Any attempt to dial the other numbers over the dial tone fail to do anything. An attempt to dial the second number listed, with 1+ area code, resulted in a human (ugh) answering. Please, tell me what I'm doing wrong... I'd just love to enjoy the rest of the show!

     Thanks for sharing this with all of us, and thanks, in advance, for any assistance!

Best regards!
Sláinte!

It is not possible to send Dial pulse over the telephone network AFTER the call is completed.
Some ATA's (voip) service will convert the DP to Touch tone. The Configuration that i have set up
is refer ed to as END to END signaling. If you have a touch tone phone and after you hear Dial tone then you  can dial the listed numbers. For the folks with Rotary dial phones only the 7,8,10,11 will
be used by the telco. When then call is set up thru the network all of the equipment that detected
the rotary or touch tone's is no longer involved with the call. With the VOIP ATA it is always there
but thru software is disabled.

this is great. Phil, I was dialing around, and dialed 211, and something that  sounds like an ANA machine reorder came on, could you explain that, please?

     Thanks for confirming my suspicions, Phil. I hated to think that after dialing a rotary for more than half a century, I had lost the ability. Apparently, all I need to do is use a DTMF phone, a dialer, or get a Panasonic 308/616, to enjoy the demonstrations.
     I was led astray from my (incorrect) interpretation of Brinybay's post... then had a duh moment, realizing I know he has a Panasonic, due to his youtube video of it.

Thanks for making this available, and I will be enjoying later.

 The 211 will reach a ANA card. I connected 211 to a Telephone number. I will read back 377-9999  I find it interesting that you were able to figure out that it was a ANA. (automatic number announcement) The selector that you hear dial tone from in sharing a common bank with other Incoming selectors (CNET) I have this selector programend with differant access than the others.

I was able to find out by the reorder, it's very distinctive to ANA's (I'm a phone phreak)

For those who remember hearing the TT to Dp sounds i added a .04 cap around the touchtone converter so you hear the pulsing, also for a month or two i placed this #541-327-4488
across my open wire o carrier system witch means it is working as a SF (single Frequency)
2600 circuit. If you have a test set that can produce 2600 you can drop and re pules into the 1st selector.  The numbers are listed in a January 20 post of this section.
211 has been disconnected.
If you are on C*NET you can reach the same circuit by calling 377-0505
If you have 2 C*NET lines you can listen to the live switch room listen in line ,this is a 24 x 7 system
C*NET 377-7777 or Thur a PSTN gateway portal 206-203-6610 follow voice prompts.
I have set up a PSTN dialable Telephone number to access my SXS system,  you will receive Real
SXS (strowger) 1968 dial tone. You can dial the following numbers. These will access differant
tones or ringing tones. None of these are computer generated. All numbers listed good 24 x 7.
Pstn Number   541-327-4488

377-9901  2 ring code pattern.                462-6199 S.C. x-y  Vacuum tube tone busy.
377-9999 Busy tone.                                462-6136 Standard ring.
377-5245 Intercept announcement.         462-62xx 120 Ipm Reorder tone. (blocked level)
                                                                 448-2512 North Electric CX 100 Ring.

OK, this forum is about Rotary Phones.  Here is something that is relavant to rotary telephones, and particularly the dial tones "way back in the good ol' days".


That post-war dial tone is a 600 Hz tone modulated by 120 Hz.  There is no way I have figured out to modulate a tone with another tone on the computer sound card.  Maybe there is, but my skills in this area are not all that good.  However, with an intergrated circuit chip, it is possible.  Last year, I did a bunch of research into old dial tone, and as a result of contacting a collector named Chuck Richards, I was able to build his circuit.


While I cannot get a computer to actually make the tone, I can, of course record the tone from the tone generator I built.  So without further adieu, here is a .wav file of the dial tone.  How many of you recognize it?
