5.2 Common CRS-170A 1:1 Redundancy Control / IF Interface Cabling
Kits
When assembling a Comtech EF Data 1:1 Redundancy System, in addition to purchasing the desired
modem pair (one Traffic Modem, one Backup Modem), you must also purchase a CRS-170A 1:1
Redundancy Control/IF Interface Cabling Kit tailored to your modem choice. Each kit provides the
CRS-170A L-Band 1:1 Redundancy Switch module and the control and IF cables required for connection
of the switch to the modems in the 1:1 redundancy configuration.
Kit usage, on a per-modem basis, is as follows:
CRS-170A 1:1
Redundancy Control / IF
Interface Cabling Kit
KT-0000160
KT/12551
1) Note these requirements:
•
The CDM-570L and CDM-570AL require a modem-specific redundancy kit, CEFD
P/N KT/10860-1. See Section 5.8.1 for details.
•
Cabling requirements for the CDM-600L (CLM-9600) Open Network Satellite
Modems are shown in Figure 5-64 in Section 5.12.
•
Cabling requirements for the SDM-300L3 Satellite Modems are shown in See
Figure 5-65 in Section 5.13.
2) Excluding Ethernet (which require user-supplied CAT5 Ethernet cables and Layer 2
switches), separately sold kits are available from Comtech EF Data to connect your
modems to a variety of terrestrial data interfaces. See the "Modem-to-User Data
Interface Connections and Examples" sections for each modem in this chapter for
examples of these kits.
