details about the CDM-710GL Modem-to-Switch Control Interface connections. See Sect. 5.8.1.2

and Figure 5-41 for details about the CDM-710GL Modem-to-Switch IF Interface connections.

The table included with each figure lists the items you will need from the KT/12551 kit for your

initial setup.

CAUTION – It is ESSENTIAL that you make the control and the IF Rx and Tx

connections correctly.
