Application No. 08/828,549
connection device, the signal structure of the data signals to data packets having a
signal structure suitable for data communication. . . ." (Appeal Br. at 29.)
Claim 17 specifies in pertinent part the following limitations: that the
aforementioned "signal processing means . . . is arranged to receive data packets
having a signal structure suitable for data communication from the computer network, to
convert the signal structure of these data packets to a signal structure suitable for
communication of data. . . ." Similarly, claim 18 specifies in pertinent part the following
limitations: "converting, by a signal processing means in a network connection device,
the signal structure of the data signals to data packets having a signal structure suitable
for data communication. . . ." Accordingly, both claims require that the aforementioned
signal processor converts the signal structure of data signals to data packets having a
signal structure suitable for data communication.
Turning to Rogers, the reference's DSP Processors 208 do not convert the signal
structure of data signals to data packets having a signal structure suitable for data
communication. To the contrary, the Processors "provide[] 'Conversion' of the new
types of CO trunk/circuits 102 with their new signaling requirements to older
PBX trunk/circuits 105 with their older signaling requirements." Col. 17, ll. 28-31.
