Cables and Connections
•
BNC connector labeled "J3 Tx" on the Switch TMI(s), to BNC connector labeled "Unbal
G.703/ASI – IN" on the Traffic CDM-625/A(s), and
•
BNC connector labeled "J5 Rx"on the Switch TMI(s) to BNC connector labeled "Unbal
G.703/ASI – OUT" on the Traffic CDM-625/A(s).
Finally, do these steps to connect and secure the Control Cable CA-0000069 (HD-15M to DB-9M,
6') between the Switch CRS-325 TMI(s) and 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).
4.4.3.5 EIA-422 Data Connections
If EIA-422 is the driving traffic data type (see Figure 4-9 through Figure 4-11):
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 make all connections as per the operating configurations:
► When you use the Switch CRS-316 TMI: 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).
Then, 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).
► When you use the Switch CRS-340 TMI: Do these steps to connect and secure the
Control/Data Cable CA/WR0066 (for control/data purposes) between the Switch TMI(s) and
the Traffic CDM-625/A(s):
•
DB-25M connector labeled "P1" on the Switch TMI(s), to
•
DB-25F connectors labeled "Data Interface" on the Traffic CDM-625/A(s).
