They're certainly real, still in use, and deployed world wide but most commonly in rural areas. They aren't particularly cost effective for most scenarios, but cheaper than hanging even a mini-DSLAM to service 1-2 customers that are too far away from a cabinet. Installing them is a pain and keeping them running long term is an even bigger pain. Certain models don't work well with specific DSLAMs and/or in specific plant combinations so testing with your DSLAMs, modems, and in your plant is a must.

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Are these thing out of date and no longer deployed ?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.
