the voice samples and then transmits them to packet network 156.
The packet data network then returns the coded voice samples to
STET voice terminal 158 for decoding. The decoding process
produces the modified voice samples which are returned to the
VQPE 152. The VQPE then processes the modified voice samples to
evaluate the performance of the voice terminal 154. See Lewis,
column 5, lines 53 through 62. Thus, Lewis teaches a signal for
a voice call provided over a packet-based communications network,
said signal comprises a plurality of packets, at least some of
which comprise test voice information as required by Appellants’
claim 11. Therefore, we find that Lewis teaches all of the
limitations as recited in Appellants’ claim 11.
Appellants argue that the test voice signal of Lewis does
not comprise any actual speech signals for a communication
session between a calling and a called party as is the case in a
voice call. See page 6 of the brief.
As we have pointed out above, the scope of Appellants’ claim
11 only requires a signal having a plurality of packets
comprising test voice information. As we have shown above, Lewis
teaches this limitation.
