Installing Indoor Equipment

Both the primary and the redundant BTR 2400s are connected to and
switched by the RPE 9000. The RPE 9000 is connected to both the RSM 9016
and the RSM 9116. The RSM 9016 is connected to the SMMs, while the
RSM 9116 is connected to the SDMs. The RSM 9016, RSM 9116, SMMs
(Signal Modulator Module) and SDMs (Signal Demodulator Module) are
installed in the NNE (Network Node Equipment unit). The SMMs modulate
ATM cells for wireless transport, while the SDMs interface RF to digital at
the base station and demodulates the QAM signal.
