5.3.1 CRS-170ACDM-625A or CDM-625 Control and IF Interface
Connections Using Cabling Kit KT-0000160
You must order terrestrial data interface components/kits separately. See Section
5.3.2 for CDM-625A or CDM-625 terrestrial data interface configuration and
connection examples and details.
You must use Comtech EF Data's KT-0000160 1:1 Redundancy Control/IF Interface Cabling Kit (Section
5.2.1) for your control and L-Band Modem-to-Switch cabling connections. Figure 5-1, Figure 5-2, and
Figure 5-3 show how to connect a pair of CDM-625A or CDM-625 modems together with the CRS-170A
L-Band 1:1 Redundancy Switch module. The table included with each figure lists the items you will need
from this kit for your initial setup.
IMPORTANT: It is ESSENTIAL that you correctly make your control and the IF Rx and Tx
connections. See Section 5.3.1.1 for details about the CDM-625A or CDM-625 Modem-to-
Switch Control Interface connection, and Section 5.3.1.2 for details about the CDM-625A or
CDM-625 Modem-to-Switch IF Interface connections.
