Dial Up Modem Sounds, from 300 bps to 56 K

The sound of dialup at some of the most common speeds, including 300, 1200, 2400, 9600, 14, 400, 33, 600, and 56K. As noted in the video, the sound of a V. 34 connection at either 28, 800 and 33, 600 will be the same, and both were common around the same time, so I ve only included the 33, 600 connection. Note that this isn t intended to be an exhaustive list of all speeds, but a sample of the most common ones. There are many other speeds and protocols, including but not limited to 75, 110, 4800, 28, 800, etc. Also note that this video includes a V. 90 56K negotiation, which is the one that people are most likely to find familiar. With that said, if it doesn t sound quite right, remember that V. 90 deprecated the X2 and Flex 56K standards, which sound quite different. All but the 56K connection is made through a Teltone TLS4 telephone line simulator, essentially a telephone network in a box. 56K connections require that the server side be connected digitally, so a Teltone ILS2000 is used instead, which does t
