D.1 Overview
See Appendix E. OPTIONAL NETWORK PROCESSOR (NP) INTERFACE MODULE
for complete information about this specific product.
The SLM-5650A Satellite Modem rear panel features two slots that accommodate optional plug-in
data interface modules. These modules plug into either the Interface Option slot that is located on
the rear panel of the SLM-5650A chassis (Figure D-1).
By convention, a modem is Data Communications Equipment (DCE) where Tx data enters the
data interface and Rx data exits. Via the chassis' internal data interface module connections,
theSLM-5650A provides physical and electrical connection between the external terrestrial device
and the internal circuitry of the modulator or demodulator.
While the SLM-5650A's available optional data interface modules are usually ordered with the
modem, they are easily field-installed. The available data interface modules and reference to their
pertinent section in this appendix are as follows:
