Appendix B. CABLE DRAWINGS
B.1 Overview
This appendix contains technical specification drawings for the cables used with the CRS-300 1:10 Redundancy Switch. These cables are
divided into three categories – User/Utility Cables (Sect. B.2), Control Cables (Sect. B.3), and Control/IF/Data Cables (Sect. B.4).
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.
The tables in Sections B.3 and B.4 cross-reference the modem-specific cabling figures featured in Chapter 4. CABLES AND
CONNECTIONS.
