CA/WR0066 cable as: a control cable between the Traffic CDM-625/A(s) and the CRS-330 or
CRS-340 TMI; as a data cable with the CRS-316 TMI; and as a combination control/data cable for
use with the CRS-340 TMI.
For specific details regarding the CA/WR0066 cable’s use as a TMI control and/or data cable, see
the data connection cabling instructions that follow for each driving traffic data type.
Additionally, when you use the CRS-316, CRS-325, or CRS-336 TMI, you must use the
CA-0000069 (HD-15M to DB-9M, 6’) Control Cable between the installed TMI(s) and Traffic
CDM-625/A(s).
See Table 4-1 in Sect. 4.4.3, and read the data connection cabling instructions that follow, for
use of this cable with the pertinent driving traffic data type.
4.4.3.2 G.703 Balanced / Unbalanced Data Connections
If G.703 (Balanced/Unbalanced) is the driving traffic data type, your means of interconnection
depends on which Switch TMI is in use. Figure 4-9 depicts use of the CRS-330 and CRS-340 TMIs
for G.703, while Figure 4-10 depicts use of the CRS-325 TMI for G.703.
G.703 traffic TMIs are not compatible with the CRS-365D Quad E1 traffic TMI when
you use both TMIs within the same Switch.
Make all connections according to the information that follows:
► If you use the CRS-330 or CRS-340 TMIs (as shown in Figure 4-9), do these steps:
First, 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 Control/Data Cable CA/WR0066 (for control
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).
Finally, do these steps to connect and secure the Data Cable CA-0000072 (DB-15F to DB-9M,
6’). Use these cables for Balanced or Unbalanced G.703 data between the Switch RMI or
TMI(s) and the Redundant and Traffic CDM-625/A(s):
• DB-15M connector labeled “P2” on the Switch RMI or TMI(s), to
• DB-9F connector labeled “Balanced G.703” on the Redundant and Traffic CDM-625/A(s).
► If you use the CRS-325 TMI (as shown in Figure 4-10), do these steps:
Specific cabling requirements apply for operation with the CDM-625/A.
