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

[John Edwards]

Vectoring can now be smarter than that.

For shorter loop lengths, it should be possible to filter out signals
below 2.2Mhz, which will allow ULL/ADSL2+ noise to be excluded from
Vectoring. Not using those frequencies at all is probably a polite
thing to do for the ULL users during a transition.

This may limit your VDSL2/17a to about 50-70mbps.

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).
