5.6.2 Modem-to-User Data Interface Connections and Examples
In addition to the Modem-to-Switch control cabling shown previously, a number of data
interface configuration kits are available for use with the CDM-760 and CDM-750 High-Speed
Trunking Modems.
5.6.2.1 RJ-45 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 5-23 shows the block diagram and a
cabling example for a CDM-760/-750 diversity switching 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.
