Chapter 4. MODEM AND SWITCH

CONFIGURATION

4.1 Overview

To avoid damage either to the modem pair or the CRS-170A switch, it is important that

you follow this sequence of configuration:

• First, configure both modems for 1:1 redundant operation as directed in this chapter. This

chapter organizes the modem-specific sections and any specific interface configuration

examples as follows:

For Modem... See Chapter Sect.

CDM-625/A 4.2

CDM-850 or CDM-840 4.3

CDM-760 or CDM-750 4.4

CDM-570L/AL 4.5

CDM-710GL, CDM-710, or CDM-700 4.6

CDM-600L (CLM-9600L) 4.7

SDM-300L3 4.8

• Second, once you properly configure both modems for 1:1 redundant operation, set the

DIP switches on the CRS-170A to the correct modem selection. See Sect.

4.9 CRS-170A

Switch DIP Settings for details.

• Third, once you properly configure both modems and the DIP switches, connect the control

and IF cables between the powered OFF modems and switch. See Chapter 5. CABLES and

CONNECTIONS for details.
