5.10.1.2 Modem-to-Switch IF Interface Connection

Excluding the modems, the KT/12551 CRS-170A L-Band 1:1 Redundancy Kit (Section 5.2.2)
provides all components shown in Figure 5-52.
IMPORTANT: The Tx IF from 'MODEM A' connects to the Tx IF port 'J5 | Tx A' on the
CRS-170A; similarly, the Tx IF from 'MODEM B' connects to the Tx IF port 'J6 | Tx B' on the
CRS-170A. The same logic applies for the Rx IF connections. It is important to note that
failure to observe this requirement will result in system malfunction.
