5.7.1.3.1.4 Modem-to-User IP (10/100 Ethernet) Interface Example

Figure 5-39 shows the block diagram and cabling example for a CDM-570L/AL 1:1 modem

configuration using the IP (10/100 Ethernet) Interface. This configuration requires no cabling kit

– you must use user-provided Ethernet cables and hub for direct connection to the ports.

For the CDM-570L/AL in Managed Switch (Ethernet Bridge) Mode, you MUST use an

external Ethernet hub to ensure that traffic will continue after a switchover. If an

Ethernet switch is used, there could be a several minute outage while the Ethernet

Switch “re-learns” the correct output Ethernet port. Using a “dumb” Ethernet hub

allows LAN to WAN traffic to continue even after a switchover occurs since both

modems will be receiving the LAN traffic.
