The CMN-16 compact modem nest is a space-saving
rack that houses up to 16 short range modem cards.
Most of the cards carry two modems, doubling the
capacity of the nest to up to 32 modems. The nest
provides an inexpensive solution to central site racking
of short range modems. In addition to short range
modems, the nest supports interface converters, fiber
optic modems and elastic buffers.
The CMN-16 is compatible with the SRM short range
modem family and has the added capability of
displaying activity on the interface signals.
