Hi Guys: I think Shidan was referring to those roadside DSLAMs (they're called OPI DSLAMs).
At a meeting in the future I could probably speak about DSL infrastructure and how it all works. As most of you know we operate our own ADSL2+ DSLAMs, but unfortunately with a very limited footprint. With regards to the CRTC regulatory issues mentioned by Doug, I'm writing another email shortly that I'm going to send to both lists. There is a lot going on that will impact everyone that uses DSL for VoIP and I'll give you the quick version (I'd like to give you the long version but I'm too busy responding to the legal briefs to fight this stuff).

The copper loop from your premises (and your DSL modem) back to the CO where it connects to the DSLAM is usually the bottleneck. There's no getting away from physics, and the more distance from your premises back to the DSLAM the weaker the signal is, and therefore the lower the maximum data rate. In the early days of DSL there were also issues that some circuits had special conditioning circuits added to help the voice service, but they would degrade the DSL service so that a circuit that should have worked correctly based only on distance would not in fact be usable. Ordering DSL when it was first offered was very unpredictable. Bell has been getting around this distance issue by installing DSLAM's outside of CO's, closer to the customer premises - I've been noticing extra little boxes bolted onto the side of many of the roadside junction boxes that act as distribution points for Bell's wiring infrastructure, which I think are these. >From what I understand Bell had been excluding other ISP's from access to this upgraded infrastructure - IANAL, but I believe their position was that the CRTC's rulings that required them to allow other ISP's to access their infrastructure at favourable prices only applied to equipment installed in the CO's. From the non-Bell ISP's perspective this amounted to Bell reserving higher performance only for Bell's own customers. I can't remember now whether the CRTC was extending (or had extended) their ruling to requiring Bell to offer access to this infrastructure, or whether the non-Bell ISP's had merely made an application that the CRTC do so.
