I mostly agree with this, but POTS starting going digital surprisingly early, before VoIP ever became a thing. And of course digitization back then was typically chopping a huge amount of the high frequencies, making things sound...well, like the phone.
- sneak 6y agoYes, but it was using TDM near exclusively in the digital domain, and not packet switching like we do now, which lead to vastly different levels of service compared to now. The problem isn't digital, the problem is packet switching. Most people making calls today have no conception of how good telephones used to be.
- titzer 6y agoSure. Packet switching allowed oversubscribing bandwidth, whereas previous digital telephony actually researched bandwidth (with TDM among other techniques).
