3.1
Using the HW 8612 as modem cable replacement
This application requires two HW 8612. One is connected to the
RS-232 interface of a PC, the other is connected to a commercial
modem connected to your phone connection box.
This structure allows for an internet access of your PC without con-
necting the PC directly to the phone connection box. The actual
connection is established between the two HW 8612. Long cables
are no longer necessary.
