I think you might getting confused here. The building blocks are just the same for a typical ADSL connection.
Yes , thanks for persevering !
With NBN you would typically have:
Ethernet switch<---> ADSL router<---> NBN terminator<---> network<----> ISP
(where terminator is a bit more fancy)
Just two more dumb questions regarding the' NBN situation' , if I may : 1/ the 'ADSL router ' connects to the NBN terminator via Ethernet; is it actually ADSL ; I thought ADSL was a phone-line technology ? 2/ It seems as though the NBN terminator can be accessed by NBN/ isp somehow;
I think Brian just got his (ASCII) diagrams round the wrong way.
you previously described this as : " NBN appears as an (long) Ethernet connection all the way to your ISP "
That's actually a very accurate description. ADSL in most other countries, and DOCSIS (Cable) networks globally run the same way. You treat the access network (ADSL, PON, DOCSIS) as though it were an Ethernet (in the classical abstract protocol sense) and just use DHCP to get your IPv4, and RA+DHCPv6+DHCP-PD to get your IPv6 address and subnet(s). The NBN OLT (box in your house/apartment) is largely the same as an ADSL modem or DOCSIS cable modem, with some extra tricks like some QoS controls, a two port SIP ATA for analog phones, and four client ports that are individually addressable.
