5.2.1.2 Switch-to-Modem IF Interface Connection

Excluding modems, the KT-0000159 1:1 Redundancy Kit (see 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-180; similarly, the Tx IF from ‘MODEM B’ connects to the Tx IF port ‘J6 | Tx B’

on the CRS-180.

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.
