My first job was with a local, rural ISP in 2001. I convinced the boss to let me have an additional account and I payed for a second phone line. Initially I used some software (on Windows 2000) to perform modem bonding (shotgun modem) with two modems. Then, eventually upgraded to Diamond Supra Sonic II 112k. It of course never reached 112k obviously but I was riding that high for quite a while.
