4.4.3.6 HSSI Data Connections
If HSSI is the driving traffic data type (see Figure 4-9 and Figure 4-10):
First, connect the Control/Data Cable CA/WR0066 (for control/data purposes) between the
Redundant CDM-625/A and the Switch RMI (see Sect. 4.4.3.1).
Next, do these steps to connect and secure the Control Cable CA-0000069 (HD-15M to DB-9M,
6’) between the Switch TMI(s) and the Traffic CDM-625/A(s):
• HD-15F connector labeled “J1” on the Switch TMI(s), to
• DB-9F connector labeled “1:1 Control” on the Traffic CDM-625/A(s).
Then, do these steps to connect and secure the Control Cable CA/WR9189-6 (HD-50M  HD-
50M, 6’) (for data purposes) between the Switch TMI(s) and Traffic CDM-625/A(s):
• 50-pin Type ‘HD’ HSSI (SCSI-II) female connector labeled “HSSI” on the Switch TMI(s), to
• 50-pin Type ‘HD’ HSSI (SCSI-II) female connector on the CIC-60 Adapter Module, to
• DB-25F connector labeled “Data Interface” on the Traffic CDM-625/A(s).
4.4.3.7 LVDS Data Connections
If LVDS is the driving traffic data type (see Figure 4-9, Figure 4-11, and Figure 4-12):
First, connect the Control/Data Cable CA/WR0066 (for control/data purposes) between the
Redundant CDM-625/A and the Switch RMI (see Sect. 4.4.3.1).
Then, do these steps to connect and secure the Control/Data Cable CA/WR0066 (for data
purposes) between the Switch TMI(s) and Traffic CDM-625/A(s):
• DB-25M connector labeled “P1” on the Switch TMI(s), to
• DB-25F connector labeled “Data Interface” on the Traffic CDM-625/A(s).
4.4.3.8 Ethernet Data Connections
1) When you use the CDM-625/A in Dedicated Management Ethernet Port mode,
this disables all four of the offline modem’s Ethernet ports unless you configure
one of the four ports as the ‘Dedicated Management Port.’ For more
information, see Sect. 5.4.13.3 CONFIG: IP  Setup in the CDM-625 or
CDM-625A Advanced Satellite Modem Installation and Operation Manuals.
2) When you use Ethernet (with no Sub-Mux) as the dedicated data interface for
the redundancy system, you must use the wired-thru method, explained in
Sect. 4.4.3.8.1, to make all cabling connections.
