4.6.3Control Y-Cable Connections – CRS-300 to Modems

All traffic data configurations require the Control Y-Cable CA/WR12069-1, connected between the CRS-300 RMI/TMI(s) and each CDM-Qx/QxL as follows:

•HD-15F connector labeled “J1” on the RMI or TMI(s), to

•DB-15M connectors labeled “Alarms” on each CDM-Qx/QxL modulator and demodulator:

oJ1 of the Control Y-Cable goes to the modulator Alarm connector. o J2 of the Control Y-Cable goes to the demodulator Alarm connector.

4.6.4Traffic Data Connections – CRS-300 to Modems

Connect and secure the cables between each CDM-Qx/QxL and the CRS-300 as follows:

If EIA-530 V.35/EIA-232 is the traffic data type, refer to Figure 4-17to connect and secure the Control/Data Cable CA/WR0066 as follows:

•DB-25M connector labeled “P2” on the RMI or “P1” on the TMI(s), to

•DB-25F connector labeled “EIA-530” on the CDM-Qx/QxL demodulator.

If Balanced G.703 is the traffic data type, refer to Figure 4-18to connect and secure the Data Cable CA/WR9038-6 as follows:

•DB-15M connector labeled “P1” on the RMI or TMI(s), to

•DB-15F connector labeled “G.703” on the CDM-Qx/QxL demodulator.

If Unbalanced G.703 is the traffic data type, refer to Figure 4-19to first connect and secure the 75Ω BNC Tx Cable CA/WR0813-8 as follows:

•BNC connector labeled “J4” on the RMI or “J3” on the TMI(s), to

•BNC connector labeled “Tx” on the demodulator.

Next, connect and secure the BNC Rx Cable CA/WR0813-8 as follows:

•BNC connector labeled “J3” on the RMI or “J5” on the TMI(s), to

•BNC connector labeled “Rx” on the demodulator.

If HSSI is the traffic data type, refer to Figure 4-20to connect and secure the HSSI Data Cable CA/WR9189-6 as follows:

•HSSI connector labeled “J2” on the RMI or “J3” on the TMI(s), to

•HSSI connector labeled “HSSI” on the demodulator.

If Quad E1 is the traffic data type, refer to Figure 4-21to first connect and secure the Quad E1 RMI Data Cable CA/WR13018 as follows:

•DB-15M connector labeled “P1” on the RMI, to

•(4X) RJ-48 connectors labeled “Port 1” through “Port 4” on the Redundant CDM-Qx/QxL.
