4.4.3.1 Control Cabling Requirement (Regardless of Driving Traffic Data
Type)
For RMI connections: The Control/Data Cable CA/WR0066 (DB-25F to DB-25M, 6’) provides the
serial communication path between the Redundant CDM-625/A and the Switch (via the CRS-310
RMI) for all driving traffic data types. You must always use this cable.
For all driving traffic data types, see Figure 4-9 through Figure 4-11 and do these steps to
connect and secure the CA/WR0066 cable between the Redundant CDM-625/A and the Switch
CRS-310 RMI:
• DB-25F connector labeled “Data Interface” on Redundant CDM-625/A, to
• DB-25M connector labeled “P1” on the Switch CRS-310 RMI.
For TMI connections: Depending on the driving data traffic type, in addition to its use as a
control cable between the Redundant CDM-625/A and the CRS-310 RMI, you may use the
