Figure B-2. CDM-710/L Rear Panel Data Interface Slots

By convention, a modem is Data Communications Equipment (DCE) where Tx
data enters the data interface and Rx data exits. The plug-in interface has full
duplex capability. In addition, the module is automatically configured for simplex-
transmit or simplex-receive operation when the module is plugged into a simplex
chassis configured for 'modulator only' or 'demodulator only' operation.
Looking at Figure B-2:
• Interface Slot 1 is located at center right of the CDM-710/L chassis rear
panel. It is filled with a data interface module first. Slot 1 will accept
either a CDI-40 ASI or a CDI-60 HSSI Data Interface Module only.
• Interface Slot 2 is located at the right side end of the chassis rear panel. It
is assigned a blank panel or a CDI-70 10/100/1000 Base-T Gigabit
Ethernet Data Interface (GBEI) Module only.
For more information about the available data interfaces and
installable module combinations, see:
