[AusNOG] NBN Services (Business TC2) and MBE cutoff?

[John Lindsay]

Of course this blows the whole forced transition to vdsl2 and the economic model that goes with it. 

It's like blowing up the original bridge over the river to maximise the toll revenue for the new bridge.

The big gap in my knowledge is what happens with ULL (ie. naked) services from other providers. Given that business SHDSL services are retained and these are essentially the same as ULL ADSL2+ services, I would have to think that ULL services will remain. Same for MBE, it's just a bunch of ULL's mashed together, so if it's staying, no reason for any ULL service not to remain ? They could of course make a distinction between ULL's for residential and ULL's for business and allow one to continue to be ordered and not the other.

Otherwise telstra (and others) would continue to happily offer DSL services at a price cheaper than a comparative NBN service and most people would happily stay with that.

They would then need to either leave the ULL go back to the existing exchange location (for ULL services to continue to work) or they end up stranding any existing ULL based services (ie. the MBE services you're talking about). There could well be a couple of different "rules" depending on what sort of NBN services the area (FTTH, FTTN, HTC, etc).
