5.10.2 Modem-to-User Data Interface Kit and Connection Examples

In addition to the basic Modem-to-Switch cabling shown previously, a number of data interface
configuration kits are available for use with the CDM-710 Broadcast Satellite Modem. Separate cabling
kits are needed for these data interfaces.
While different data interface cards may be installed into both Interface slots, only one data
interface type is operable at a given time. The data interface combinations allowable in the
CDM-710 chassis Interface Slots 1 and 2 are as follows:
5.10.2.1 Modem-to-User Non-IP Data Interface Kit and Connection
Examples
Figure 5-53. CDM-710 Block Diagram – UserModemSwitchTraffic
Figure 5-53 shows the block diagram typical for the kits shown in Sections 5.10.2.1.1 and 5.10.2.1.2. For
example, Section 5.10.2.1.1 identifies the interface kit used with the CDI-40 ASI 75Ω data interface.
With the exception of the CDI-70 Gigabit Ethernet data interface configuration shown in Section
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).
