May 8, 2014 at 17:29 | comment | added | Spiff | @DoktoroReichard Sure, it was in Wikipedia's article on CSD: "Prior to CSD, data transmission over mobile phone systems was done by using a modem, either built into the phone or attached to it. Such systems were limited by the quality of the audio signal to 2.4 kbit/s or less." Although I note that this mention does not cite a source itself. | |

May 3, 2014 at 16:47 | comment | added | Doktoro Reichard | @Spiff for completeness sake, could you add the online reference that stated the 2400 bps limit in your answer? | |
May 1, 2014 at 20:31 | comment | added | Spiff | @Generalkidd D'oh! I just realized that in my last two comments, I was only thinking about one direction of audio. So I deleted those comments. I still don't think the cables you've linked to will work, because you need a transformer between the telephone line and the audio jack. I think you'd need something like this, in addition to creating your own adaptor from that pair (one input, one output) of 3.5mm jacks on that box, to a 3.5mm phone headset plug. | |
May 1, 2014 at 19:32 | comment | added | Generalkidd | What about this cable? It appears to be an RJ-9 to RJ-11 cable. ebay.com/itm/… | |
May 1, 2014 at 17:45 | comment | added | Generalkidd | Could I theoretically use a combination of these: showmecables.com/product/… ebay.com/itm/… in order to hook up my phone to the modem? | |
May 1, 2014 at 11:09 | comment | added | MSalters | @Keltari: That's why GSM has a Fax protocol too, besides Voice and CSD ;). GSM was truly designed as a digital network, with the intent to do more than just voice. | |

Apr 30, 2014 at 22:35 | comment | added | msb | I'm not sure I understand this answer. @Spiff starts saying "No", then goes on to explain how it actually can be possible, even though highly difficult to implement and getting a very low bandwidth. Right? ... | |

Added a lot more about dialup-like technologies over digital cell networks.

Apr 30, 2014 at 20:45 | comment | added | Keltari | This is a problem for analog faxes on digital phone lines as well | |
