Jason (and other interested parties).

IMHO The problem I see is that the Linksys SPA-2102 VoIP ATA is not 
line powered, meaning powered from the telephone circuit. This means 
that the local mains, aka hydro power, must be present for the ATA to 
work. In an emergency this might not be the case.

I would be interested in seeing if the Direct Detect equipment is, 
itself, line powered. Most (if not all) DSL circuits in KW are 
provided by Bell regardless of whether the ISP is Bell or another 
business who is reselling the Bell DSP circuit. I suspect, but I am 
not certain, that whether or not there is telephone service on the 
DSL circuit, that the 48 Volt loop voltage is  present on the circuit.
