According to Wikipedia:

QUOTE
The first broadband platform rolled out known as Phase 1 network was based on FTTC (fibre to the curb) design with nodes being placed within 300 metres of premises.  SDH backbone is used to transport voice, data and video whereas VDSL technology is used as the access network to get customers connected to TransACT's high-speed broadband and digital TV services.  [...]

The Phase 2 rollout involved TransACT placing its own DSLAM equipment within Telstra exchanges and utilising their own fibre-optic backhaul to their main data centre in Dickson, ACT. TransACT completed their ADSL 2/2+ rollout on 1 March 2007.  The Phase 2 network is available to anyone outside Phase 1 with a Telstra phone line in Canberra and Queanbeyan, as long as they are within sufficient distance of their telephone exchange – as with any ADSL service.

The FTTC claim above is consistent with the map I mentioned in an earlier email - see http://nbnmtm.australiaeast.cloudapp.azure.com/nbnmtm.html - which also shows large parts of Canberra as being 100 Mbit/s FTTC.


> Still, Transact FTTN VDSL2 through cat5 cabling is nearly always going to be better than NBN FTTN.  A lot of people are pretty happy with transact VDSL2.  I wonder who in NBN made the decision to duplicate the VDSL2 network?  It beggars belief.

CAT5 cabling for VDSL2 and the nodes within 300 metres of premises - luxury!  No wonder people are happy with TransACT.  And, yes, implementing a parallel NBN network with nodes connected over old Telstra copper for up to a kilometre or more sounds almost bizarre.
