4.3.1.4.1.1 10/100 Ethernet using Single Port Router Mode
In this example, the 10/100 Ethernet port labeled “2” is used on the Redundant and
Traffic modems.
For 1:N connections between the CRS-500 CSU and CDM-625 Modems: When using 10/100
Ethernet in Router Mode, for any Traffic Modem where only a single port of Ethernet Router
mode traffic data is desired, the modem 10/100 Ethernet port “1” connections are reserved for
10/100 Ethernet System Communication and must not carry 10/100 Ethernet traffic data.
Referring to Figure 4-5:
• First, for the Redundant Modem, connect a single PP/CAT5FF7FTGY cable between the
Redundant Modem and the CRS-510 RMI:
o
Any single modem RJ-45 10/100 Ethernet port labeled “2” through “4” to
o
Any single corresponding CRS-510 RMI RJ-45 10/100 Ethernet port labeled “Port2”
through “Port4”.
• Then, for each Traffic Modem, depending on how many ports are employed for each
interface, connect a single PP/CAT5FF7FTGY cable between each CRS-520 TMI and its
designated Traffic Modem:
o
Any single CRS-520 TMI RJ-45 10/100 Ethernet port labeled “Port 2” through “Port
4” to
o
Any single corresponding modem RJ-45 10/100 Ethernet port labeled “2” through
“4”.
