Figure 5-54 shows the block diagram typical for the kits shown in Sects. 5.10.2.1.1 through
5.10.2.1.3. For example, Sect. 5.10.2.1.1 identifies the interface kit used with the CDI-10 Dual
G.703 E3/T3/STS-1 and CDI-60 HSSI data interfaces.
With the exception of the CDI-70 Gigabit Ethernet data interface configuration shown in Sect.
5.10.2.2, which uses user-provided Ethernet cables and Layer 2 Switch, you must use one
interface kit per 1:1 modem pair for each interface (see examples for specific quantities).

Figure 5-55 shows an example of a CDM-700 1:1 modem configuration with the CDI-10 Dual
G.703 Data Interface installed in Slot 1, and the CDI-60 HSSI Data Interface installed in Slot 2.
The figure depicts installation of one KT/12582 Dual G.703 Interface Kit (each kit can supply one
or two CDI-10 interfaces), and one KT/12586 HSSI Interface Kit.
