3.1 Cabling Connection Types
The cable and connector types described in this section are commonly used in many Comtech EF
Data products. Each cable type is typically dedicated to a specific mode of operation.
The plug-in interface cards (including the CRS-230 System Controller card and a variety of Traffic
Modem Interface (TMI) and Redundant Modem Interface (RMI) cards) that are available for use
with the CRS-300 may not use all of these connector types.
The European EMC Directive (EN55022, EN50082-1) requires that you use properly
shielded cables for DATA I/O. These cables must be double-shielded from end-to-end,
ensuring a continuous ground shield.

Figure 3-1 show the coaxial cables (plugs) and their mating connectors (jacks/sockets) that
