5.5.2 Unit-to-User Data Interface Connections and Examples
In addition to the Unit-to-Switch control cabling shown previously, the CDM-840 features a
single 10/100/1000 Gigabit Ethernet RJ-45 data interface port, and a G.703 Unbalanced E1 data
interface for use with the CDM-840’s optional E1 Interface/RAN Optimization Hardware/FAST
Feature upgrade.
With the exception of the 10/100/1000 Gigabit Ethernet Interface configuration shown in Sect.
5.5.2.1, which requires user-provided Ethernet cables and a Layer 2 switch, you will need one
cable and component kit per 1:1 unit pair for each user interface (see examples for specified
quantities).
5.5.2.1 RJ-45 Gigabit Ethernet Data Interface Example
Figure 5-20 shows the block diagram and cabling example for a CDM-840 diversity switching
configuration using the RJ-45 10/100/1000 Gigabit Ethernet port. This configuration requires no
cabling and component kit – you must make a direct connection with user-provided Ethernet
cables and a Layer 2 switch.
