CRS-300 1:10 Redundancy Switch Revision 16
Cables and Connections MN/CRS300.IOM

4.4.2 User Data Connections – CRS-300 to User
The User’s traffic data from multiplexing equipment or a test data generator should connect to the
connectors labeled “User Data Interface” on the TMI(s). This interface replaces the direct
connection to the Traffic Modem’s “Data Interface” connectors.

1. Because the Redundant Modem’s function is to replace a faulted Traffic
Modem, the RMI does not have a User Data Interface.
2. Ensure that the correct operation for Balanced or Unbalanced G.703
data is configured on the modem.
For T1/E1 operation, the optional CN-0000268 T1/E1 Adapter (illustrated in Figure A-32 in
Appendix A. CABLE DRAWINGS) may be purchased from Comtech EF Data to adapt the
Balanced G.703 DB-15F connector on the User data side of the TMI to a RJ-48 female connection.
4.4.3 ESC Data Connections – CRS-350 to Modems
Refer to Figure 4-8 to connect and secure the cables between the CRS-350 and each CDM-600/600L
modem as follows:
• Connect and secure the CA/WR0066 cable:
o DB-25F connector on the CRS-350, to
o DB-25M connectors labeled “P3A Overhead” on the CDM-600/600L.
• Connect and secure the CA/WR9038-6 cable:
o DB-15M connector on the CRS-350, to
o DB-15F connectors labeled “P5A IDR Alarms” on the CDM-600/600L.
• Connect and secure the CA/WR9932-1 cable:
o DB-9M connector on the CRS-350, to
o DB-9F connectors labeled “P4A Audio” on the CDM-600/600L.
4.4.4 User ESC Data Connections – CRS-350 to User
The User’s equipment should be connected to the correct corresponding plug-in card on the front
panel of the CRS-350. This replaces the direct connection to the Traffic Modem’s “IDR”, “Audio”
and “Overhead” ports. Refer to
Figure 1-26 in Chapter 1.5 CRS-350 ESC Switch Description for
detailed information on this interface.
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 1.4.3 Modem Interface Cards for detailed information on the RMI and TMI
cards available for use with the CDM-600/600L modems.
