Wired-Thru Connections; Wired-Around Connections - Comtech EF Data CRS-300 Installation And Operation Manual

CRS-300 1:10 Redundancy Switch
Cables and Connections
BNC connectors (four connectors per installed CDI-10 card) on each Traffic CDM-700
•
(depending on the modem configuration, either <4X> or <8X> BNC connectors are used).
If HSSI is the traffic data type, see Figure 4-31 and Figure 4-34 and do these steps to connect
and secure the HSSI Data Cable CA/WR9189-6 between the Switch and each CDM-700:
HSSI (HD-50F) connector labeled "J2" on the Switch RMI, or "J3" on the Switch TMI(s), to
•
HSSI (HD-50F) connector labeled "HSSI" on each CDM-700.
•
If OC-3 copper is the traffic data type, see Figure 4-32 and do these steps to connect and
secure the pair of BNC PL/0813-8 cables between the Switch and each CDM-700:
BNC connectors labeled "J4 Tx" on the Switch RMI, or "J3 Tx" on the Switch TMI(s), to BNC
•
connectors labeled "Tx" on the CDM-700's CDI-50 plug-in module, and
BNC connectors labeled "J3 Rx" on the Switch RMI, or "J5 Rx"on the Switch TMI(s), to BNC
•
connectors labeled "Rx" on the CDM-700's CDI-50 plug-in module.
4.10.5 Ethernet Traffic Data Connections – CRS-300 to Modems
You have two choices for handling Ethernet traffic data:
If the Traffic Modem uses Ethernet as the sole traffic data type, then you must route the
•
Ethernet data through the Switch like G.703 or HSSI data. This is known as the wired-thru
method for processing data through the Switch.
If the Traffic Modem uses Ethernet plus another data type like G.703 or HSSI, then the
•
Ethernet data can be routed around the Switch. This is known as the wired-around method
for processing data around the Switch.

4.10.5.1 Wired-thru Connections

For the wired-thru connection method, see Figure 4-32 and Figure 4-33. Do these steps to
connect and secure the CAT5 Data Cable PP/CAT5FF7FTGY between the Switch and each CDM-
700:
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 modules.
•

4.10.5.2 Wired-around Connections

For the wired-around connection method, see Figure 4-34 and Figure 4-35. Do these steps to
connect and secure the CAT5 Data Cable PP/CAT5FF7FTGY for each CDM-700:
