  1. Since you can't easily do MF, why not modify the code to pulse out 2600 when you push the digit keys, like the old pre-MF step tandems used?

     

    Timing should be 66 milliseconds of 2600 Hz, followed by 34 milliseconds of silence for each pulse, with about 500 milliseconds between each digit:

     

    Digit zero would be 10 sequences of 66ms/34ms 2600, with a 500ms pause before the next digit, for example.

     

    You still need to define a key to play 2600 for about 1.5 seconds for trunk seizure.

     

    You could also write the code to accept a number, then outpulse the entire number with the correct timings.

     

    There is a number on CNET that this can be used to dial with.

     

    This is essentially the method used by Cap'n Crunch and Joe Engressia to phreak step tandems or switches that accepted older SF trunks from step tandems. Routes that used this method of tone signalling were already pretty rare back in the late 60's and early 70s when they used this technique. You had to discover a number that routed through a step tandem from your dialing location, usually by trial and error. Vancouver, BC in Canada had one such switch.

    That seems very smart, I am going to attempt to do that. I am new to basic, so this will be a challenge.

    http://sourceforge.net/projects/virtualt/Here is an emulator for model 100/102/200 if you want to try it out. Thanks for the idea!

  2. I seem to recall the TELCOM dialer worked only by doing dial pulsing (loop interrupt) on the phone line connected  to the jack. No DTMF dialing at all!

    Oh, Does the TELCOM dialer work with an acoustic coupler?

     

    And, thanks for the info.

     

    [EDIT] I recall in the manual, they say that the acoustic coupler cannot autodial. But i am not sure.

    Great video! I had not seen that.

     

    I got mine for $20.00 from Ebay 5 years or so ago. They cost thousands back when I ordered a few for a test lab back in the 80s.

     

    Here's my second-favorite trunk tester - A Sage 930A. It is much more capable than the 314A, but it's not blue!

     

     
     
    I have two of these.....One with a T1 interface.

     

    That is pretty cool, why is it more capable than the 314a? The LCD screen?

     

    Keep em' comin'

    CNET gateway for above payphone: +1 (206) 203-6610

     

    When dial tone plays, dial: 1-762-0001

     

    After one ring, payphone answers with a beep. IMMEDIATELY dial *123456. Phone reads back coin box total. Press * again for cumulative total. Repeat as often as desired.

     

    If you don't dial the first * quickly enough after the beep, or if the payphone doesn't hear the DTMF, a modem answer tone will play.

     

    D.

     

    On Protel phones, you can tell the phone the coinbox is empty. *#5 and whatever four digit passcode was defined during setup. By default, it's 1111. Doesn't do anything except reset the coin counter (accessible on *#4xxxx), but it's there.

     

    On my Ernest D3 COCOT, you can check the current and cumulative coin box totals by letting the phone auto-answer after the set number of rings and entering a DTMF code before the internal modem tone plays.

     

    I have the phone on CNET, accessible through one of the CNET gateways.

     

    1-762-0001

     

    After 1 ring, the phone auto-answers. To check coin box totals, press *123456 after beep but before modem tone. Press * again for cumulative total. May or may not work over VOIP due to poor Asterisk 1.2 DTMF handling.

    Thats pretty cool! I tried it.

  5. (THE STORY)

    I recently ordered a TRS-80 model 100 and I have been waiting for it to come, (probably going to come on 3/23/15) I started creating a DTMF (Dual Tone Multi Frequency) Tone Dialer. And I noticed that you cannot just input frequencies, you have to enter the weird musical code, so I found the musical code and converted freq to code (example: 2600hz = 940) If anyone has knowledge on how to play two tones at once, please reply.

     

     

    (THE QUESTION)

    If anyone has knowledge on how to play two tones at once using the sound command, please reply. (The sound command uses the musical code, then timing.

     

    (For example, 2600hz for 3/4th of a second =

     

    SOUND 940,100

    )

    I had the original Kyocera version of the Model 100. Radio Shack bought the design from Kyocera. I had the same idea for a blue box app at the time, but found it wasn't possible.

     

    The built-in BASIC had no provisions for polyphonic output. Furthermore, one could not just specify a frequency in Hz, but entered an integer in a 16-bit range that mapped to a specific frequency, followed by a tone duration.

     

    Don

    I know, I made a 2600hz single tone generator for it, and 2600hz for 1/2 seconds =

     

    10 sound 940,75

     

    Why was it not possible?

    I can find the frequencies, but I cannot play two tones at once.

    An Arduino-based "Blue Box". It produces the "traditional" Blue Box 2600Hz tone and MF (multi-frequency) tones, but does much more. It also produces 12 tone signalling systems used by phone phreaks to hack other more exotic system in the US and overseas, including early pre-cellular mobile telephone systems from the 50s, 60s, and 70s.

    Wow! that 314A is pretty awesome! Where did you get it? Also, I have seen your blue box videos online, pretty cool! I am planning on getting an arduino soon so I can make something similar, but anyways, good job!

    It makes it even better that its cased in a bluebox...  Heres a vid

  9. I had one of these, they were pretty nice for their time though the built in modem is only 300bps.

    you can program in basic and assembler on them, but they only have 32k of memory.

    I'd suggest getting a casette tape or optical drive for it.

    Yeah, I am probably going to purchase a cassette tape drive.  And by the way, I an new to BASIC and I want to ask you something. Do you know how to play two different tones at the same time using the "sound X,Y" command? Because I want to make a DTMF Dialer software, and I cant figure that out. But anyways.

    Thanks!

  10. I ordered a TRS-80 Model 100 yesterday night, and I got an emulator ( http://sourceforge.net/projects/virtualt/) and I found out that you could output sound. So, like a good phreak, I tune to 2600hz, add a cool textart logo, and boom. 2600hz tone on the tip of a button. (This is for Nostalgic reasons, I dont plan on using this) But, once the TRS-80 model 100 comes, I will rewrite the program on that, and take a video.

    I am new to basic programming, so it is not beautiful, but it does the trick. If any of you guys have ever done things like this, reply to this topic and tell me. I am interested in creating a DTMF Dialer software, but, the model 100's sound output is meant for creating music, not tones, so sadly, I cant just input the frequencies and assign them to each number. [ (EXAMPLE) 2600hz = 940 ]

     

    (The model 100 will probably come on the 23.)

    [EDIT] IF ANYONE KNOWS HOW TO PLAY TWO TONES AT ONCE (using the "sound (pitch),(time)" commands, please reply.

    •Generic Pushbutton (red and black) (circa 1950)

     

     

    I'm sorry... your estimated date is wrong by 13 years. 

     

    Touch-tone was invented in 1963.

     

     

    •At&t 210 (dark brown) (1980)

     

    Are you sure it was made in 1980 because this set must've been made after 1984. The AT&T logo proves it.

     

    Oh, Thanks! about what year would you think that the red and black pushbutton desk set is from?

    That sounds interesting, Ill have to try it sometime.

     

    Thanks!
