On the question about RIM optics, you have to keep in mind that a RIM is POTS only, to get DSL, an AM35 was shoehorned into the cabinet and used the RIM's multiplexer for backhaul. To upgrade the backhaul, it's not as simple as changing optics you need a completely new backhaul. CMUXs have the same issue, they have DSL capabilities, but the backhaul is just tacked on to the side of the POTS capacity. It may all seem like poor planning in 2012, but back when these decisions were made, we were talking 20% takeup and 256Kbps plans.<div>

We use VDSL Services from a carrier called FirstPath in the Sydney CBD areas, they have fibre fed DSLAM'S in buildings.<br>

And because ACIF approval came too late to be useful.<br>
<br>
And because the NBN has been hanging over the industry like a sword of Damocles for the last five years, so nobody has been planning any major new fixed network rollouts, thereby denying Australian consumers the benefits of higher-speed technologies in the interim.<br>
