Appendix C. OPTIONAL PIIC
(PLUG-IN INTERFACE CARD)
MODULES
C.1 Overview
The CDM-760 Advanced High-Speed Satellite Modem rear panel features two slots that
accommodate optional PIIC (Plug-in Interface Card) data modules. These modules plug into
either or both of the Interface Option slots located on the rear panel of the CDM-760 chassis
(Figure C-2).
By convention, a modem is Data Communications Equipment (DCE) where Tx data enters the
data interface and Rx data exits. Via the chassis’ PIIC module connections, the CDM-760
provides physical and electrical connection between the external terrestrial device and the
internal circuitry of the modulator or demodulator.
While the CDM-760’s available optional PIIC modules are usually ordered with the modem, they
are easily field-installed. The available PIIC modules, and reference to their pertinent section in
this appendix, are as follows:

Additional PIIC module data options (ASI, HSSI, etc.) will become available upon
request.
Any PIIC module supported by the CDM-760 can be used in any slot. In Single Stream Mode, a
single PIIC module is active and no other interfaces are active. In MultiStream Mode, one or
