ADSL Line Extenders

[Jean-Francois Mezei <jfmezei_nanog () vaxination ca>]

A friend on a rural DSl association asked about ADSL line extenders.

A search on Google yields many products dating back to the days of
ADSL-1 advertising 1mbps profiles, but a few seem more recent and
support ADSL2+ (not sure if any support VDSL2).

Are these thing out of date and no longer deployed ? Were they ever
effective, or just vapourware that didn't really improve things ?


Do any Telcos still deploy them ?  Anyone know of deployments in Canada ?

I just need a reality check on those devices.
