The LMJA-8125/8300 can be used in conjunction with multiple NB-Routers and an NB-Switch. These components are usually housed
inside an LMNC DLM Network Component Enclosure. Each router communicates with one segment. There is a maximum of 300 rooms
or common spaces controlled by a single LMJA-8xxx, and the maximum of 40 per segment still applies. Therefore a typical application
with close to 300 rooms/spaces (and up to 2000 DLM devices) might use between seven and nine routers, depending on how many
devices are connected in each segment. (As mentioned previously, Wattstopper recommends not fully loading a controller to maximum
capacity, to allow for future changes or additions to the segment.)
