5.6.2 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 configuration kits are available for use with the CDM-760 and CDM-750 High-Speed

Trunking Modems.

5.6.2.1 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 5-29 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.
