Telecom will be offering FS/FS and FS/128kbps UBS plans from 26th October 2006. FS/FS replaces the existing 3.5mbps offerings.
ISP's can request interleaving turned off for a UBS service.
This is avaliable for all ISP's with a wholesale agreement with Telecom, not just those in the ComCom ruling.
Also this may be of interesting to some if you didnt already know:

What some of the more astue members of the telco industry have pointed out is that as the number of adsl services increases cross talk also increases. Also as the amount of spectrum utilized increases (eg number of frequency bins) cross talk again increases.
So faster DSL for all actually means slower DSL for some, no change for many and some improvement for a few. This is before you even take into account the backhaul contention.
