56k modems' upstream speeds were limited to 33.6kbps due to analog-to-digital conversion at the phone company. However, downloads could reach 56kbps because they leveraged a mostly-digital path from the telco's server to the user's modem. This asymmetry existed because the phone company's infrastructure used digital signals internally, even for analog phone calls. The digital audio was converted to analog only at the last mile, at the user's local central office. This meant a 56k modem downloading data was essentially receiving a slightly-modified digital signal, bypassing much of the analog conversion process and thus achieving higher throughput. Uploads, originating from the analog modem, had to be fully digitized at the central office, resulting in the lower speed.
Several Hacker News commenters pointed out that the article's title is misleading. They clarified that 56k modems didn't rely on digital phone lines in the way the title implies.
