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.
