I understand that older DSL modems aren't compatible with newer technology, but is the case same the other way around? I.e.:
- Is VDSL2 modem compatible with a VDSL connection? What about with ADSL or ADSL2 line?
- Is VDSL modem compatible with an ADSL/2 connection?
- Is ADSL2 modem compatible with an ADSL connection?
- Or could it be so that *2 modems are downwards compatible only with *2 connections (this is just guessing...)
Or is there other logic? Or are they all just incompatible?
Sadly your question is too broad. – Francisco Tapia – 2015-11-26T16:02:55.160
1I'm not sure, but you're probably being too general - while every (ADSL2+) modem I've used has been able to choose an older mode automatically (or manually), it's probably firmware/hardware specific: even if all hardware is able to do this, firmware may have technical or even intentional (locking) restrictions against it. – Bob – 2012-02-25T08:55:00.213
