I now have ULL Annex M ADSL2+ ;D
How did I get this? I'm part of the trial of Internode's NakedDSL rollout.

1.4 I've been told I'm on a "pair-gains" line and can't get ADSL. What do I do?
Unfortunately there's not much you can do.
A pair-gains system is a digital switch that allows a whole bunch of people to share a limited number of lines rather than having an individual line (pair) per person all the way back to the exchange. This allows, for example, 100 homes to share a 50 pair line.
These are installed for several reasons such as a stopgap as in the case of a street that is developed faster than expected (or not expected), and/or a cost saving measure at the time, particularly where there are physical difficulties with providing a larger cable.
Although they are an excellent means of providing adequate voice services to an area quickly, it is not physically possible to connect ADSL through a pair gains switch because the "pair" is constantly switching plus the digital switching method would probably conflict with the ADSL signal anyway.
Getting a 2nd line is no guarantee that you won't just get another pair-gain line so there's really no solution other than changing address.
A jointly funded venture by Telstra and the Commonwealth Government called the Internet Assistance Program has helped people get off pair gains systems, and Senator Kate Lundy has a Website for victims of pair-gains for those who want to add their voices.
1.5 I've been told I'm on a "RIM" and can't get ADSL. What do I do?
A RIM is a "Remote Integrated Multiplexor" and is basically a chunk of the main Telephone exchange broken off and moved closer to an area. These are linked back to the main exchange with optic fibre via a switching mechanism which, you guessed it, is digital and won't work with ADSL because the CMUX needs to be connected to copper lines (not fibre), and the cost and space limitations of providing these inside RIMs has been prohibitive.
However, Telstra are developing a mini-CMUX solution for RIMs, but at this stage there is no information to hand about when this project will be in full swing or when it will be completed. See Senator Kate Lundy's site mentioned above to voice a complaint, and the Internet Assistance Program may also be able to help.
Update: Up to 60% of RIMS will not be capable of having a "mini-mux" fitted. More at Whirlpool.

Do you know if you were on a rim?
