Cabling Kit KT/12551
You must order terrestrial data interface components/kits separately. See Sect.
5.10.2 for CDM-700 terrestrial data interface configuration and connection examples
and details.
You must use the Comtech EF Data KT/12551 1:1 Redundancy Control/IF Interface Cabling Kit
(Sect. 5.2.2) for your control and L-Band Unit-to-Switch cabling connections. See Sect. 5.10.1.1
and Figure 5-52 for the CDM-700 Modem-to-Switch Control Interface connection details. See
Sect. 5.10.1.2 for the CDM-700 Modem-to-Switch IF Interface connections details. The table
included with each figure lists the items you will need from the KT/12551 kit for your initial
setup.
CAUTION – It is ESSENTIAL that you make the control and the IF Rx and Tx
connections correctly.
