@sabi for the most part: #HSCSD @ 115,2 kBit/s (mostly due to throttling on #3G networks which peaked at 7,2MBit/s...

But the absolute first was 64kBit/s #ISDN...

@kkarhan more people than I thought had ISDN! I’ve only personally known one person who had an ISDN connection and it wasn’t his first. I did know the admin for my local ISP who at one point had four 33.6 modems in some sort of bonded configuration which was pretty rad but obviously not his first modem either.

@sabi local telco offered 20hrs p.m. of ISDN with free channel bonding for ~ €15 p.m. back then...

@sabi @kkarhan had ISDN? I recently hooked up an ISDN phone again to make SIP calls ;)

@sabi @kkarhan I worked for Pacific Bell Internet in the '90s. the product manager for ISDN used to say, "it's so hard to explain and sell that internally we call it I Still Don't kNow"

@datn @sabi Whereas in #Germany #ISDN was more of a norm than exception to the point that only senior citizens that only paid for the basic must-offer landline didn't have it...

In fact, ISDN phone system cablings are so common CPEs like AVM's "#FritzBox" still offer the S0 bus interface to this day since every small office used that - espechally when cordless #DECT systems weren't an option...

@sabi @kkarhan I used ISDN in Switzerland from 1997 before I could get cable around 1999

@PeterSommerlad @sabi @kkarhan ISDN 64kBit/s, played with channel bonding to have 128kBit/s. Ran a server that dynamically added the second channel on demand, i.e. high usage. Worked great as ISDN connections have no "handshake elevator music".

@sabi @kkarhan Where I lived in Sweden, if you wanted a second phone line (for a home business), they were likely to give you ISDN. So all my friends with a parent running a business started out on ISDN.
