See Sect. 4.2.2 in this chapter for details of the CDM‐625 Modem‐to‐Switch Control Interface
connection, and Sect. 4.2.3 for details of the CDM‐625 Modem‐to‐Switch IF Interface
connections. Here, Figure 4‐1 through Figure 4‐3 show how to connect a pair of CDM‐625
modems together with the CRS‐170A L‐Band 1:1 Redundancy Switch module; the table that
accompanies each figure lists the cables provided in KT‐0000160 for this initial setup.
