Ethernet Traffic Data Connections - CRS-300 to Modems
To handle Ethernet traffic data, the User has two choices:
•
If the Traffic Modem uses Ethernet as the only data type needed , then the Ethernet data
should be routed through the CRS-300 Switch like G.703 or HSSI data. This method of
processing data through the CRS-300 is referred to as wired-thru .
•
If the Traffic Modem uses Ethernet and another data type like G.703 or HSSI, then the
Ethernet data can be routed around the CRS-300. This method of processing data around
the CRS-300 is referred to as wired-around.
For detailed information on these two approaches, refer to
CONFIGURATIONS
4.7.5.1 Wired-thru Connections
For the wired-thru connection , refer to Figure 4-24 and Figure 4-25 to connect and secure the
Cat5 Data Cable PP/CAT5FF7FTGY between the CRS-300 and each CDM-700 as follows as
follows:
•
RJ-45 connector labeled "J5" on the RMI or TMI(s), to
•
RJ-45 connector labeled "J1" on the CDM-700 (CDI-70) interface cards.
4.7.5.2 Wired-around Connections
For the wired-around connection , refer to Figure 4-26 and Figure 4-27 to connect and secure
the Cat5 Data Cable PP/CAT5FF7FTGY for each CDM-700 as follows:
•
RJ-45 connector labeled "J1" on the CDM-700 (CDI-70) interface card, to
•
RJ-45 connector on the User-provided Ethernet switch
4.7.6
User Data Connections – CRS-300 to User
The User's traffic data (from an external router, multiplexing equipment or test data generator)
should connect to the connectors on the TMI labeled "User Data Interface". This interface
replaces the direct connection to the Traffic CDM-700's "Data Interface" connectors.
If the User chooses to wire-around for Ethernet traffic, the User traffic interface will be on the
customer provided switch.
Because the Redundant CDM-700's function is to replace a faulted Traffic CDM-700, the RMI
does not have a User Data Interface.
Refer to
Chapter 1.4.4 Modem Interface Cards
