User Traffic Data Connections
The user traffic data from an external router, multiplexing equipment or test data generator should
connect to the TMI connectors labeled “User Data Interface.” This interface replaces the direct
connection to the Traffic Modem’s “J5 | DATA” or “J6 | DATA” ports.
Because the Redundant Modem’s function is to replace a faulted Traffic
Modem, the RMI does not have a User Data Interface.
