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, and is therefore
always required.

Refer to Figure 4-30 and Figure 4-31 to connect and secure the CA/WR12361-1 cables
between each CDM-710G and the CRS-300 as follows:

• HD-15F connector labeled “J1” on the RMI or TMI(s), to
• DB-15M connector labeled “P1 Alarms” on the CDM-710G.

4.9.4

Serial Traffic Data Connections – CRS-300 to Modems

If G.703 is the traffic data type

, refer to Figure 4-30 to connect and secure the pair of BNC

PL/0813-8 cables between the CRS-300 and each CDM-710G as follows:

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

connectors labeled “Tx J3” on the CDM-710G’s CDI-10-1 interface card, to

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

connectors labeled “Rx J2” on the CDM-710G’s CDI-10-1 interface card.

If HSSI is the traffic data type

, refer to Figure 4-31 to connect and secure the HSSI Data Cable

CA/WR9189-6 the CRS-300 and each CDM-710G as follows:

• HSSI (HD-50F) connector labeled “J2” on the RMI or “J3” on the TMI(s), to
• HSSI (HD-50F) connector labeled “J1 HSSI” on the CDM-710G’s CDI-60

interface card.

4.9.5

Ethernet Traffic Data Connections - CRS-300 to Modems

To handle Ethernet traffic data, the User routes the Ethernet data through the CRS-300 Switch
like G.703 or HSSI data. This method of processing data through the CRS-300 is referred to as
wired-thru

. For detailed information on this method, refer to

Chapter 3. ETHERNET

NETWORK CONFIGURATIONS

in this manual.

For the wired-thru connection, refer to Figure 4-31 to connect and secure the Cat5 Data Cable
PP/CAT5FF7FTGY (RJ-45 to RJ-45, 7’) between the CRS-300 and each CDM-710G as follows:

• RJ-45 connector labeled “J5” on the RMI or TMI(s), to
• RJ-45 connector labeled “J1” on the CDM-700 (CDI-70) interface card.

4.9.6

User Data Connections – CRS-300 to User

The User’s traffic data (from an external router, multiplexing equipment or test data generator)
should connect to the connectors on the TMI labeled “User Data Interface”. This interface
replaces the direct connection to the Traffic Modem’s “Data Interface” connectors.

Because the Redundant Modem’s function is to replace a faulted Traffic Modem, the RMI does
not have a User Data Interface. Refer to

Chapter 1.4.4 Modem Interface Cards

for detailed

information on the RMI and TMI cards available for use with the CDM-710G modems.
