4.9.6 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 Modem’s “Data Interface” connectors.
Because the Redundant Modem’s function is to replace a faulted Traffic Modem, 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-710 modems.
