5.3.2 Modem-to-User Data Interface Connections and Examples
In addition to the control and IF switch-to-modem cabling shown in the previous section, a
number of data interface configuration kits are available for use with the CDM-760 or CDM-750.
5.3.2.1 Gigabit Ethernet Data Interface Example
The CDM-760/-750 provides a ‘J7 | OPTICAL’ port and two Plug-In Interface Card (PIIC) slots for
optional data traffic handling. Both modems otherwise feature two 10/100/1000 Gigabit
Ethernet RJ-45 data interface ports by default. Figure 5-18 shows a block diagram and cabling
example for a CDM-760/-750 1:1 modem configuration using these RJ-45 ports (this example
shows use of both ports). This configuration requires no cabling and component kit – you must
use user-provided Ethernet cables and Layer 2 switches for direct connection to the modems.
