software, along with third party
components, offers a toolkit with a
variety of functions to support IP
Phone implementations. This includes
voice applications services that access
DSP services and support APIs neces-
sary for implementation of call pro-
cessing features. Sample code for
device drivers and network manage-
ment is provided. An industry-leading,
enhanced security framework is also
available, using an IPSEC engine to
provide DES/3DES/AES encryption/
decryption services. Additional pack-
ages include full signaling services
with standard network protocols, SIP,
H.323 and MGCP. Figure 1 shows the
IP Phone software architecture.

It includes acoustic echo cancella-
tion for full duplex speakerphone
capability (when used in a properly
designed enclosure), support for
three-way conferencing and support
for low bit rate and wideband
internal Ethernet Switch with dual
MAC and PHY provides support for
IP Phone and PC connectivity to the
Ethernet LAN.
The TNETV1050 IP Phone proces-
sor has a USB 1.1 controller and PHY
that support either USB host or
peripheral. The USB interface allows
for a wide variety of possible devices
to connect to the phone for user
value-add. These devices support
applications such as card readers,
fingerprint recognition, PDA syn-
chronization, video conferencing, etc.
The TNETV1050/1055 solutions also
support TI’s VLYNQ™ interface, a
low cost, low pin count and low com-
plexity chip-to-chip serial interface.
VLYNQ makes it easy to add off-chip
