4.7.5Ethernet 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 Chapter 3. ETHERNET NETWORK CONFIGURATIONS in this manual.

4.7.5.1 Wired-thru Connections

For the wired-thru connection, refer to Figure 4-24and Figure 4-25to 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.

4.7.5.2Wired-around Connections

For the wired-around connection, refer to Figure 4-26and Figure 4-27to 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

4.7.6User 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 for detailed information on the RMI and TMI cards available for use with the CDM-700 modems.
