Step 1: Install ferrite cylinders as explained in this chapter.
Step 2: Install an EIA/TIA 232-D cable between the modem's DTE connector and the
DTE or PC serial port. Tighten the cable-connector retaining screws.
Step 3: Unplug the telephone cord from the wall jack and plug it into the modem’s
PHONE LINE connector
Step 4: Attach the modular audio cable (provided with the modem) to the modem’s DIAL
LINE connector. Connect the cable to the RJ-11 dial line wall jack.
Step 5: Plug the power cable into the modem, and then plug into an outlet.
IMPORTANT:
Transmit levels on a leased line are typically much greater than those on
a dial line. Do not connect a modem to the dial network when the modem is
configured for leased line operation; the telephone company
may detect a fault
condition and initiate an incorrect service call.
