5.4.2 Modem-to-User Data Interface Connections and Examples

In addition to the control and IF switch-to-modem cabling shown previously, a number of data
interface configurations are available for the CDM-570/A.
5.4.2.1 Modem-to-User Non-IP Data Interface Connections and Examples
The block diagram shown in Figure 5-24 is typical for the examples shown in Sects. 5.4.2.1.1
through 5.4.2.1.3.
With the exception of the CDM-570/A 10/100 Ethernet Interface configuration shown in Sect.
5.4.2.2, where user-provided Ethernet cables and hub are used, one cable/component set per
1:1 modem pair is required for each user interface (see examples for specific quantities).
