5.3.2.4.2 Unbalanced G.703 Traffic Data Cable Connections
1. G.703 Unbalanced traffic is possible only when the modem is equipped with the optional
G.703 Plug-In Interface Cards (PIIC). This traffic data type requires use of the CRS-345
TMI.
2. The Redundant Modem

DSU RMI and DSU TMI

Traffic Modem CA-0000069 control
cable connections should have already been made, as directed in Section 5.3.2.2 .
3. The Redundant Modem

CSU CRS-512 and DSU TMI

Traffic Modem
PP/CAT5FF7FTGY Ethernet Comm cable connections should have already been made,
as directed in
Section 5.3.2.3.2 .
See Figure 5-11. Do these steps:
1. For the Redundant Modem, connect the CA-0000750 Cable (4X BNC to DB-9F, 6’)
between the Redundant Modem G.703 PIIC and the CRS-505 RMI:
a. First, connect cable BNC connector ‘1’ to the PIIC “RX-OUT” port, and cable
BNC Connector ‘2’ to the PIIC “TX-IN” port; then, connect to
b. CRS-505 RMI DB-9M connector labeled “P1 | G.703/ASI”.
2. For each Traffic Modem, connect the CA-0000703 Cable (4X BNC to DB-9F, 6’) between
each CRS-345 TMI and its respective Traffic Modem PIIC:
a. For single module connections (see Figure 5-11 for TMs 2 and 4):
•
CRS-516 TMI DB-9M port labeled “P1 | BNC Adapter” to
•
(Slot 1 PIIC) Cable BNC Connector ‘1’ to the PIIC “RX-OUT” port, and cable
BNC Connector ‘2’ to the PIIC “TX-IN” port.
b. For dual module connections (see Figure 5-11 for TM 6):
•
CRS-516 TMI DB-9M port labeled “P1 | BNC Adapter” to
•
(Slot 1 PIIC) cable BNC Connector ‘1’ to the PIIC “RX-OUT” port, and cable
BNC Connector ‘2’ to the PIIC “TX-IN” port, and
•
(Slot 2 PIIC) cable BNC Connector ‘3’ to the PIIC “RX-OUT” port, and cable
BNC Connector ‘4’ to the PIIC “TX-IN” port.
