Space! ESS and DMS systems also sit on a smaller footprint than SxS and X-bar systems.
Got to maximize revenue somehow.
BTW, the DMS-100 in my city handles 51 exchanges. In addition there are several other switches in the building.
I note the map feature is interesting. There's a whole cluster of switches in Providence.
