Enthusiasts bond twelve 56K modems together to set dial-up record: 668kbps

Summary

The latest episode published by tech channel The Serial Port began with an interesting question: Is it possible to stream YouTube via dial-up internet? As the headline suggests, the answer is a resounding yes, with our intrepid heroes managing to establish a connection offering download speeds of 668.8 kbps. The feat was eventually achieved using an era-appropriate Windows XP PC, a Cisco VoIP unit, a couple of serial port packing PCI cards, and a dozen 56K modems bonded using Multilink PPP (MPPP) technology. This is probably a world record.success!

Back then, connectivity was slow, but by the turn of the millennium, websites and communications were simpler and had lower bandwidth. For example, downloading multimedia files like MP3s back then could tie up your phone line for 10 to 20 minutes. Thus, applications like the infamous Napster and emerging streaming video and online multimedia experiences begged for broadband.Multilink PPP technology was one possible solution to faster internet connectivity before ISDN and ADSL connectivity became widespread. As the name suggests, MPPP tech combines the bandwidth of multiple modems to create a single logical data pipe.Commercial solutions like “the Diamond Multimedia Shotgun, a PCI card with two onboard modems that could be bonded together using multilink PPP,” leveraged this tech, point out the YouTubers. However, it didn’t gain traction due to the multiple lines and ISP shenanigans required.Now, with an ISP that supports digital modems and the equipment (including a Cisco VoIP gateway) to make it happen, The Serial Port had an opportunity to see how far Multilink PPP can go. Encouragingly, the official MPPP standard doesn’t highlight any practical limits…Cover your ears - Preparing...
