development license, software
training and complete IP Phone
reference design for immediate
demonstration and development.
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 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.
Silicon Solution
The IP Phone Solution includes a
programmable TI C55xTM 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's VLYNQTM 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.

Description
The TNETV1050 is a communica-
tions processor based on a MIPS32
Reduced Instruction Set Computer
(RISC) processor along with a
C55x DSP. This device has
a rich peripheral set architected
specifically for VoIP Phone
applications, which reduces the
bill of materials cost, time, and
complexity to develop an IP
Phone. The TNETV1050 combines
the key processor, communication,
and peripheral functions necessary
to build a basic or advanced
IP phone. The TNETV1050
architecture uses advanced design
features to provide flexibility and
performance throughput, while
conserving power consumption.
Combined with Telogy Software
for IP Phone applications, the
TNETV1050 provides a complete
hardware/software solution
capable of reducing system
design cycle times.
The RISC processor supplies
the overall system services and
performs user interface, network
management, protocol stack
management, call processing, and
task scheduling functions. The
DSP processor provides real-time
voice processing functions such
as echo cancellation, compression,
PCM processing, and tone genera-
tion/detection.
IP phone designs are simplified
through on-chip peripherals such
as a 16-bit color LCD controller,
8x8 keypad interface, USB 1.1
controller (Host or Device), UART
serial interface, programmable
serial port, two VLYNQ interfaces,
and several general purpose I/O.
The integrated dual-channel
16-bit CODEC includes the critical
functions needed for IP Phone
applications, including two ADCs
(with five programmable inputs)
and two DACs (with four
programmable outputs).
Other codec features include
analog and digital sidetone control,
anti-aliasing filter, programmable
gain options, and programmable
sampling rate (8 or 16 ksps).
