CRS-170A L-Band 1:1 Redundancy Switch
Cables and Connections
5.6.2 Unit-to-User Data Interface Connections and Examples
In addition to the control and IF Unit-to-Switch 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 Section
5.6.2.1, 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).
5.6.2.1 RJ-45 Gigabit Ethernet Data Interface Example
Figure 5-30 shows the block diagram and cabling example for a CDM-840 1:1 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.
