market. Inheriting market proved Infineon VoIP system technology and CODEC/SLIC design, VINETIC
offers the flexible VoIP solution with the best-in-class Voice over IP processing capability in CPE devices.
Figure 1
As illustrated, a typical VoIP CPE system with analog telephone interface is built up by several major function
blocks. First is the SLIC (Subscriber Line Interface Circuit), its function is to supply the ringing voltage, DC-feeding
and line current sensing. The analog voice signal needs to be sampled and digitized to PCM signal for further
processing and CODEC is working here as the A/D or D/A converter. Last but not the least, the voice signal needs
to be coded by certain compression algorithm (e.g. G.729) and packetized into RTP so will be sent to Network
controller for further transmission. On the other hand, for voice packet coming from network side, the VoIP
processor works as decoder and generate the PCM voice stream from packetized voice. VINETIC
integrated system solution for those or one of the function blocks. It supports G.711, G.726 ADPCM,G.723.1
G.729A/B/E, iLBC voice coder and T.38 FAX relay, as well as the network voice processing features like Jitter
Buffer, Line Echo Cancellation, VAD, CID, AGC etc. The CODEC/SLIC features are programmable to fullfill the
world wide analog telephone requirements.
From a 1-channel low-end VoIP analog adapter to the multi-channel FXS/FXO VoIP router; from the VoIP DECT
basestation to a xDSL home gateway with FXS/FXO for both analog and ISDN lines, today’s VoIP CPE products
are featuring variable VoIP capabilities. To cover these applications, the members of VINETIC
designed to be hardware pin- and software-compatible, allowing the maximum flexibility while offering the
optimized feature set per application.

independent in order to enable the easy porting to any other embedded operation system. On the top level of driver
software there is Telephone Application Programming Interface (TAPI) which gives developer the way to fast
realize high level applications. All series devices are software compatible.
