CDM-625/625A Traffic Data Cable Connections
5.3.1.4.1 10/100 Ethernet Traffic Data Cable Connections
5.3.1.4.1.1 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-625/625A 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.
See Figure 5-5 . Do these steps:
1. For the Redundant Modem, connect a single PP/CAT5FF7FTGY cable between the
Redundant Modem and the CRS-510 RMI:
a. Any single modem RJ-45 10/100 Ethernet port labeled “2” through “4” to
b. Any single corresponding CRS-510 RMI RJ-45 10/100 Ethernet port labeled
“Port2” through “Port4”.
2. 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:
a. Any single CRS-520 TMI RJ-45 10/100 Ethernet port labeled “Port 2” through
“Port 4” to
b. Any single corresponding modem RJ-45 10/100 Ethernet port labeled “2”
through “4”.
