Quick speed comparison of some of the most common dial-up speeds, including 300, 1200, 2400, 9600, 14,400, 33,600, and 56K. The increase in speed is pretty dramatic. Bell 103 was released in 1962, 2400 V.22 was released in 1984, with 56K V.90 formally released in 1998 (though 56K modems using X2 and Flex were available as early as 1995).
All but the 56K connection is made through a Teltone TLS-4 telephone line simulator, essentially a 'telephone network in a box'. 56K connections require that the server side be connected digitally, so a Teltone ILS-2000 is used instead, which does the same job but for ISDN (read: digital) phone devices. In this configuration the analog 56K modem is connected to the network via a DIVA T/A ISDN terminal.
