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‐750.
4.3.6.1

RJ-45 Gigabit Ethernet Data Interface Example

When no optional data interfaces are installed via the available J7 Optical port or Plug‐In
Interface Card (PIIC) slots, by default the CDM‐750 provides a 10/100 Ethernet data interface via
two copper RJ‐45 Gigbabit Ethernet (also referred to as GigE or GbE) Interface ports. Figure 4‐21
shows a block diagram and cabling example of a CDM‐750 1:1 modem configuration using these
RJ‐45 ports (this example depicts use of both ports). Direct connection is made with user‐provided
Ethernet cables and Layer 2 switches, so no cables or kit is required.
