Digital Signal Processor (DSP)
and a MIPS32鈩?4KEc鈩?processor,
combined with the field-proven
VoIP Telogy Software鈩?product.
TI鈥檚 TNETV1050 IP Phone
solution leverages TI鈥檚 investment
in communication processors for
VoIP and broadband applications
to provide the superior processing
horsepower needed to support
current and evolving IP phone
standards, as well as the addition
of advanced functionality.
One of the unique features
of TI鈥檚 IP Phone solution is the
accompanying starter kit. The
starter kit includes the software
development license, software
training and complete IP Phone
reference design for immediate
demonstration and development.
The Telogy microprocessor
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 necessary for implementation
of call processing features. Sample
code for device drivers and network
management is provided. Additional
packages include full signaling services
with standard network protocols, SIP,
H.323, and MGCP. Figure 1 shows the
IP phone software architecture.
The TNETV1050 IP Phone
product provides the functionality
required for today's executive
enterprise desktop speakerphones.
It includes acoustic echo cancellation
for full duplex speakerphone capabil-
ity (when used in a properly
designed enclosure), support for
three-way conferencing and support
for low bit rate and wideband codecs.

Telogy Software for IP Phone
Applications
Telogy Software provides an
efficient framework for real-time
voice processing that has been
pre-integrated and rigorously
tested. The complete DSP solution
feature set includes: PCM reception,
tone generation, acoustic echo
cancellation, voice activity detection,
voice playout, and a variety of voice
compression options. The solutions
are provided in several packages to
allow customization for a full range
of phone products.
The IP Phone Solution includes a
programmable TI C55x鈩?DSP for
optimal IP Phone voice processing
and signal processing features. The
MIPS32 4KEc processor provides a
standards based RISC architecture
for customer ease in feature develop-
ment and integration with Telogy
Software services. The three port
line rate internal Ethernet Switch
with dual MAC and PHY provides
support for IP Phone and PC
connectivity to the Ethernet LAN.
The IP Phone processor has a USB
1.1 controller and PHY that support
either USB host or peripheral. The
USB interface; allows for a wide vari-
ety of possible devices to connect to
the phone for user value add. These
devices support applications such as
card readers, fingerprint recognition,
PDA synchronization, video confer-
encing, etc.
The TNETV1050 also supports
TI鈥檚 VLYNQ鈩?interface; a low cost,
low pin count and low complexity
chip-to-chip serial interface. VLYNQ
makes it easy to add off-chip co-
processors and peripheral capability
to the phone. VLYNQ enables the
customer to bring in value-added
features such as video/multimedia,
wireless connectivity, security,
speech recognition and more.
