Modem-to-Switch IF Interface Connection

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.
