Modem-to-User Data Interface Connections and Examples

In addition to the control and IF Modem-to-Switch cabling shown previously, a number of data interface
configurations are available for the CDM-570L or CDM-570AL or CDM-570L.
5.8.1.3.1 Modem-to-User Non-IP Data Interface Connections and
Examples
The block diagram shown in Figure 5-40 is typical for the examples shown in Sections 5.8.1.3.1.1
through 5.8.1.3.1.3.
With the exception of the CDM-570L ONLY IP (10/100 Ethernet) Interface configuration shown in
Section 5.8.1.3.1.4, where you must use user-provided Ethernet cables and hub, you will need one cable
and component set per 1:1 modem pair for each user interface (see examples for specific quantities).
