5.3.1.2 Modem-to-Switch IF Interface Connection

Excluding modems, the KT-0000160 CRS-170A L-Band 1:1 Redundancy Kit (Sect.

5.2.1) provides all components shown in Figure 5-2.

EXAMPLE: 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.
