4.10.4 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 Modem’s “Data Interface” connectors.
Because the Redundant Modem’s function is to replace a faulted Traffic Modem, 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 SLM-5650/5650A modems.
4.10.5 ESC Data Connections – CRS-350 to Modems
Refer to Figure 4-35 to connect and secure the Control/Data Cable CA/WR0066 between the rear
panel of the CRS-350 and each SLM-5650/5650A as follows:
• DB-25F Jxx “Overhead” connector on the CRS-350 rear panel (where xx specifies the
numbers 1 through 10 Traffic SLM-5650/5650As, and “R11” is reserved for the
Redundant SLM-5650/5650A), t o
• DB-25M “P1 Overhead Data” connector on each SLM-5650/5650A.
4.10.6 User ESC Data Connections – CRS-350 to User
The User’s equipment should be connected to the correct corresponding plug-in User Data
Interface (UDI) card on the front panel of the CRS-350. This replaces the direct connection to the
Traffic SLM-5650/5650A’s “Overhead” port.
