In this link http://youtu.be/vvr9AMWEU-c http://youtu.be/vvr9AMWEU-c you can hear an additional sound pattern at the end that is not explained in the article or the image, but I remember hearing it every time I connected via modem. Can someone explain what it is?
- cowpewter 12y agoThat extra twangy bit means the modems negotiated a V.92[1] connection instead of a v.90 connection. Just a newer protocol, that was a bit faster, but required cleaner phone lines to negotiate successfully. I spent 6.5 years of my life working technical support for a dial-up ISP. Listening to the handshake (when the user had two phone lines so they could attempt a connection with us on the line to listen) was a valuable diagnostic tool.
