4.8.3 Control Cable Connections – CRS-300 to Modems
The Control Cable CA/WR12361-1 provides the serial communication path between the Switch
and the modems and controls the modem’s external Tx IF-mute control line. You must always
use this cable.
See Figure 4-26 and Figure 4-27 and do these steps to connect and secure the CA/WR12361-1
cables between the Switch and each CDM-710G/710GL:
• HD-15F connector labeled “J1” on the Switch RMI or TMI(s), to
• DB-15M connector labeled “P1 Alarms” on the CDM-710G/710GL.
4.8.4 Serial Traffic Data Connections – CRS-300 to Modems
If G.703 is the traffic data type, see Figure 4-26 and do these steps to connect and secure the
pair of BNC PL/0813-8 cables between the Switch and each CDM-710G/710GL:
• BNC connectors labeled “J4 Tx” on the Switch RMI or “J3 Tx”on the Switch TMI(s) to BNC
connectors labeled “Tx J3” on the CDM-710G/710GL’s CDI-10-1 plug-in module, to
• BNC connectors labeled “J3 Rx” on the Switch RMI or “J5 Rx”on the Switch TMI(s) to BNC
connectors labeled “Rx J2” on the CDM-710G/710GL’s CDI-10-1 plug-in module.
If HSSI is the traffic data type, see Figure 4-27 and do these steps to connect and secure the
HSSI Data Cable CA/WR9189-6 the Switch and each CDM-710G/710GL:
• HSSI (HD-50F) connector labeled “J2” on the Switch RMI or “J3” on the Switch TMI(s), to
• HSSI (HD-50F) connector labeled “J1 HSSI” on the CDM-710G/710GL’s CDI-60 plug-in
module.
4.8.5 Ethernet Traffic Data Connections – CRS-300 to Modems
To handle Ethernet traffic data, you must route the Ethernet data through the Switch like G.703
or HSSI data. This method of processing data through the Switch is referred to as wired-thru. For
detailed information on this method, see Appendix A. ETHERNET NETWORK CONFIGURATIONS
in this manual.
For the wired-thru connection, see Figure 4-27 and do these steps to connect and secure the
CAT5 Data Cable PP/CAT5FF7FTGY (RJ-45 to RJ-45, 7’) between the Switch and each
CDM-710G/710GL:
• RJ-45 connector labeled “J5” on the Switch RMI or TMI(s), to
• RJ-45 connector labeled “J1” on the CDM-700 (CDI-70) plug-in module.
