As with all questions of moderate or greater complexity, the correct answer
is, "It depends." :-)
At the start of DSL synchronisation, the DSL line card at the switch/remote
and your DSL modem negotiate the highest speed practical on the actual line
at that moment. That speed is constrained by the maximum configured, but
rarely reaches it due to line conditions. It's not just loop length, but
(especially with old loops) phantom taps from abandoned service, condition
of splices and/or moisture in the junctions/splice sleeves, state of the
insulation, presence of loading coils that should have been removed, etc.
Or perhaps TELUS tells you a different story on SSI :-) ? I know they
upgraded much of the island from "long-loop" DSL to fiber, but not sure
whether that reached you.
