• HSSI connector labeled “HSSI” on the demodulator.
If Quad E1 is the traffic data type, see Figure 4-25 and do these steps to first connect and
secure the Quad E1 RMI Data Cable CA/WR13018:
• DB-15M connector labeled “P1” on the Switch RMI, to
• (4X) RJ-48 connectors labeled “Port 1” through “Port 4” on the Redundant CDM-Qx/QxL.
Next, do these steps to connect and secure the (4X) Quad E1 TMI Data Cables (CEFD P/N
PP/CAT5FF7FTGY):
• RJ-48 connectors labeled “Port 1” through “4” on the Switch TMI(s), to
• RJ-48 connectors labeled “Port 1” through “Port 4” on the Traffic CDM-Qx/QxL.
4.7.5 User Data Connections – CRS-300 to User
You must connect your traffic data from the 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-Qx/QxL modems.
