Modem-to-User Non-IP Data Interface Connections and Examples

The data cables and components identified in each of the examples that follow in this
section must be purchased separately, as required.
In addition to the control and IF Modem-to-Switch cabling shown previously, a number of data interface
configurations are available for the CDM-625A and CDM-625 Advanced Satellite Modems. The Figure
5-4 block diagram is typical for the examples shown in Sections 5.3.2.1.1 through 5.3.2.1.8.
With the exception of the IP (10/100 Ethernet) Interface configurations shown in Section 5.3.2.3 (which
use customer-supplied Ethernet cables and Layer 2 switches), you must use one cabling and component
kit per 1:1 modem pair for each user interface (see examples for specific quantities).
