In particular, how much does this cost ISPs compared to BUBA? I'm only referring to the per port/user cost, not the other behind the scenes stuff like handover etc. I presume this isn't a secret. The ComCom document doesn't list any calculations for the 0 kbps option.
In fact, and this leads me to my second point, it doesn't discuss the 0 kbps at all from what I've seen. And so too in earlier discussions, it seems 0 kbps wasn't mentioned at all. So am I right this is a new thing, and on Telecom's initiative? When did the 0 kbps option become available?
Finally considering that the key advertised advantage of EUBA is the priority channel for VoIP, am I right that the primary difference from an end user's POV between EUBA 0 kbps and BUBA is that EUBA 0 kbps offers ADSL2+ whereas BUBA technically does not? I do understand that there's are structured differently and so for the ISP things aren't so simple.
