Chapter 5. CABLES
AND
CONNECTIONS
5.1 Overview
This chapter identifies the modem-specific CDS-100 Diversity Switch Kit and the auxiliary data
interface cables or kits required for that particular configuration.
1) The terms “1:1 Redundant Operation” and “1:1 Redundancy” are
interchangeable with the term “Diversity Switching”.
2) The cables required between each modem and Switch should be of shielded,
twisted-pair construction, with the grounded shield bonded to the back shell.
All data cables should be wired correctly using the pinout and connection
information as specified in Appendix A. CABLE DRAWINGS.
3) It is physically impossible to connect all available data interface solutions
within a single diversity switching system at a given time. For example, when
using the CDM-625/A in a Diversity Switching System, you is unable to establish
an ASI interface together with a G.703 Unbalanced interface, or an EIA-422/232
interface together with an HSSI interface. Therefore, the quantities of cables
and accessories furnished with each kit have been predetermined with this
operational limitation taken into consideration.
4) The type of 1:1 Y-Splitter cable required for modem-to-user interconnection
depends on your data interface. It is essential to ensure that the control
connections are made correctly.
5) The Electronic Industries Association (EIA) designations supersede the
Recommended Standard (RS) designations. References to the old designations
may be shown when depicting actual text (e.g., RS-232) displayed on Switch or
the individual modem Web Server pages, serial remote interfaces, Telnet
Command Line Interfaces (CLIs), or unit rear panels. All other references in the
manual refer to EIA designations.
6) The sections in this chapter that identify the Diversity Switch Kit required for
your modems are as follows:
