or suggestion of the use of the sound card within the PC 118 in
Figs. 1 and 3 for telephony purposes.
The speakerphone and cordless telephone approaches discussed
at column 17, lines 26 through 42 are based upon
interconnectabilities utilizing the modem only and do not appear
to teach or suggest the use of the PC 118 and its sound card 320
to implement this telephone functionality.
Figs. 15 and 16 of this reference are two different versions
of the video conferencing system. The Fig. 15 system utilizes
the ability to have microphone and speaker inputs connected to
the public telephone network PSTN generally shown as element 1510
in Fig. 15. Again, this approach does not utilize the sound card
320 of personal computer 118 in Figs. 1 and 3.
Finally, the alternative video conferencing approach unit
Fig. 16 is that portion of Schindler most relied upon by the
examiner as the basis for the telephone handset capability. The
discussion of this figure begins at the bottom half of column 20.
The dashed item 1622 in Fig. 16 is stated at column 20, lines 52
through 57 as indicating a voice capability as an optional
advanced feature.
