Overview

AP-VTC1000 network Voice Transcoder device is a voice codec transcode device for network based digital voice recording and processing function along with AddPac VoIP gateway device. It is a network Voice Transcoder which is composed of two ports 10/100/1000Mbps Gigabit interface, DSP module slot for multi voice codec support.

IP based voice communication is growing fast as a substitution of existing PSTN phone network in accordance with fast network BcN (Broadband Convergence Network) such as ADSL, VDSL, and FTTH.
The demand for voice recording solution has been increasing in the structure of PSTN network and internet network. To meet the needs of customer satisfaction, next generation voice solution should be able to fulfill voice recording in PSTN network as well as in VoIP (Voice over IP) based internet network.
AddPac network based voice recording solution supports not only voice recording solution in one access point but it also supports total voice recording service architecture in BcN (Broadband convergence Network) along with various IP based VoIP devices such as analog/digital VoIP gateway, IP phones, and IP-PBX. IP based PSTN voice recording solution would satisfy the needs of demand.

Embedded Type Network Voice Codec Transcoder

AddPac AP-VTC1000 network voice codec transcoder device supports network based voice codec transcode service with high performance CPU module, real time OS (APOS), and embedded hardware

It has both a high performance RISC processor which support Gigabit Ethernet and stabilized embedded OS to optimize the performance and efficiency. This is a device for voice recording server (without voice codec transcode function) and convert G.723, G729, G726 into G.711. A voice recording server performs to save/manage the voice signal from various end-point based on G.711 and helps to transmit to media player.

Firmware Upgradeable Hardware Architecture

AddPac AP-VTC1000 IP Voice Transcoder’s high performance RISC module is a programmable structure so that it is capable of improving functions, altering, and adding new features constantly. When additional features or changes are needed, simply download from the homepage or setting an auto upgrade option. You may use the latest features without much effort.

Support DSP Module for Multi Voice Codec

AddPac AP-VTC1000 IP Voice Transcoder supports a real time high quality voice codec transcode solution based on the state-of-the-art technology DSP. A captured voice data from end-point (VoIP gateway, IP Phone, etc) will be transmitted to commercial based recording server through IP network after voice transcoding. It not only provides voice codec such as G.711, G.726, but also low bit rate VoIP such as G.729, G.723.1. Transcoder module supports up to 64 channels with PCM (G.711).

A recorded voice data based on G.711 can be listened through speaker or headset.
