4.10.6 User Data Connections – CRS-300 to User
You must connect your traffic data from the external router, multiplexing equipment, or test
data generator to the connectors on the Switch TMI labeled “User Data Interface”. This interface
replaces the direct connection to the Traffic CDM-700’s “Data Interface” connectors.
If you choose the wire-around method for Ethernet traffic, your traffic interface will be on the
user-provided switch.
Because the Redundant CDM-700’s function is to replace a faulted Traffic CDM-700, the Switch
RMI does not have a User Data Interface.
See Sect. 1.4.3.3 Modem Interface Cards for detailed information on the Switch RMI and TMI
cards available for use with the CDM-700 modems.
