Why didn't they ever upgrade ISDN to ADSL speeds and beyond, or designed an ISDN-over-PON? Was it cost reasons?

- dsr_ 2y agoOh, they did. It's just that ISDN died in the USA. If someone from Germany can chime in, I believe they had higher-bandwidth ISDN services in the late 1990s onwards.
- bobdvb 2y agoRegular ISDN is 64k and then 128k bonded BRI. You could go to E1/PRI to get 2048kbps for €€€€. In North America ISDN was 56k due to the slower T1 it was sent in and framing.
