4.11.2 User Data Connections – CRS-300 to User
You must connect your traffic data from the multiplexing equipment or a test data generator to
the connectors labeled “User Data Interface” on the Switch 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 Switch RMI does not have a User Data Interface.
2) Ensure that you correctly configure modem operation for Balanced or
Unbalanced G.703 data.
For T1/E1 operation, the optional CN-0000268 T1/E1 Adapter (see Figure B-32 in Appendix B.
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 Switch TMI to a RJ-48 female connection.
4.11.3 ESC Data Connections – CRS-350 to Modems
See Figure 4-37 and do these steps to connect and secure the cables between the CRS-350 and
each CDM-600/L modem:
• 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/L.
• 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/L.
• 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/L.
4.11.4 User ESC Data Connections – CRS-350 to User
You must connect your equipment to the correct corresponding plug-in module on the CRS-350
front panel. This replaces the direct connection to the Traffic Modem’s “IDR”, “Audio” and
“Overhead” ports. See Figure 1-24 in Sect. 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 Switch RMI
does not have a User Data Interface.
