It is possible to download up to 30 KB/sec on dial-up, i've done it to. Even though one may have a 56k modem, there're limiters installed on them. Sometimes they buzz out and allow you to actually download faster. The fastest, legally allowable connection for dial-up as defined by the FCC is 53 kbps, meaning a max downstream of 6.625 kb/sec. Anything faster is illegal, but not impossible. Just the same, if one were to remove the limiter in a 33.6 modem, it could probably perform like a 56k.
