First, do these steps to connect the Control/Data Cable CA/WR0066 (for control 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 Data Cable CA-0000072 (DB-15F to DB-9M,
6’), between the Redundant CDM-625/A and Switch RMI:
• DB-9F connector labeled “Balanced G.703” on the Redundant CDM-625/A, to
• DB-15M connector labeled “P2” on the Switch RMI.
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 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).
Finally, for Balanced G.703 data only, do these steps to connect and secure the Data Cable
CA-0000072 (DB-15F to DB-9M, 6’) between the Switch TMI(s) and Traffic CDM-625/A(s):
• DB-15M connector labeled “P2” on the Switch TMI(s), to
• DB-9F connector labeled “Balanced G.703” on the Traffic CDM-625/A(s).
–or–
For Unbalanced G.703 data only, do these steps to connect and secure the pair of PL/0813-
8 cables (75Ω BNC to BNC, 8’):
• BNC connector labeled “J3 Tx”on the Switch TMI(s) to BNC connector labeled “Unbal
G.703/ASI – IN” on the Traffic CDM-625/As, 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).
4.4.3.3 G.703 Quad E1 Data Connections
If Quad E1 is the driving traffic data type (see Figure 4-11 and Figure 4-12), do these steps:
First, connect the Control/Data Cable CA/WR0066 (for control purposes) between the Switch
RMI and the Redundant CDM-625/A (see Sect. 4.4.3.1).
Next, do these steps to connect and secure the Data ‘Y’ Cable CA-0000073 (DB-15F to <2X>
DB-9M, 6’) between the Switch RMI and the Redundant CDM-625/A:
• DB-15M connector labeled “P2” on the Switch RMI, to
