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. The block diagram shown in Figure 4‐22
is typical for the examples shown in Sects. 4.4.4.1 through 4.4.4.3.
With the exception of the 10/100 Ethernet Interface configuration shown in Sect. 4.4.4.4, 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 specified quantities).
