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.
