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-710GL High-Speed Satellite Modem. Separate
cabling kits are needed for these CDM-710GL 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-710GL chassis Interface Slots 1 and 2 are as follows:
Single G.703 (CDI-10-1)
5.9.2.1 Modem-to-User Non-IP Data Interface Kit and Connection
Examples
Figure 5-47. CDM-710GL Block Diagram – UserModemSwitchTraffic
Figure 5-47 shows the block diagram typical for the kits shown in Sections 5.9.2.1.1 and Section
5.9.2.1.2. For example, Section 5.9.2.1.1 identifies the interface kit used with the CDI-10-1 Single G.703
data interface.
With the exception of the CDI-70 Gigabit Ethernet data interface configuration shown in Section 5.9.2.2,
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).
