Modem-to-User Data Interface Connections and Examples
Appendix A. CABLE DRAWINGS
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 switch-to-modem cabling shown previously, a number of data
interface configurations are available for the CDM-625 and CDM-625A Advanced Satellite
Modems. The block diagram shown in Figure 4-4 is typical for the examples shown in Sects.
4.2.4.1 through 4.2.4.9.
With the exception of the 10/100 Ethernet Interface configuration shown in Figure 4-13, where
customer-supplied Ethernet cables and Layer 2 switches are used, one cable/component set per
1:1 modem pair is required for each user interface (see examples for specified quantities).
