PSTN Alarm receiver data card
The data card With PCI socket
Special DSP processing system, dispose
of recording and playing independent digital sound real time and efficiently.
Special DSP processing system, each linear digital sounds record and paly can work at the same time separately.
Select different sound coding speed dynamically to compress and extract, such as ADPCM with 32kbps, PCM of 64 kbps
Reliable dual-tone multifrequency(DTMF) inspecting. It can start the DTMF button while recording or playing sound.
Special signal generation and detection arithmetic, precisely recognize any tone frequency signal or generate any tone frequency signal
Reliable dual-liner analogue repeater ringing inspecting
With function of polarity reversal, know if the phone is handed up precisely
Calling Identity Delivery function
With bus line of ST-BUS and MVIP-BUS, exchangeable between any two CH. In the system.
With build in processor and high capacity storage, will not cost the host cache
