1.2 Features
1.2.1 Physical Description
The CDM-760 Advanced High-Speed Trunking Modem is constructed as a 1RU-high rack-
mounting chassis. Handles at the front allow easy placement into and removal from a rack. The
unit can be free-standing if desired.
Physically, the modem is modular in design and is comprised of four major card assemblies, with
an internal expansion slot on the modem card that accepts other option cards such as Carrier-in-
Carrier (CnC) and K4 GZip lossless compression. Two Plug-In Interface Card (PIIC) slots are
provided on the modem rear panel to implement a variety of data interface options; this space
is also available to accommodate the optional High-Speed Packet Processor card.
