PCI card interface
The unique DSP processing structure, can real-time, highly efficient digital recording every line of independence and playback.
The unique DSP processing structure, each line of the digital recording and playback can simultaneously and independent.
Can dynamically select a different voice encoding speed, and real-time speech compression and decompression, such as the 32kbps ADPCM, 64kbps PCM.
Provided the reliable buttons (DTMF) detection, the recording and playback, immediate response DTMF buttons.
The unique signal Generation) and (Detection algorithm identification (can accurately identify the audio signal frequency of arbitrary or any of the audio signal frequency.
Reliable pressure control or sonic test.
With a caller id (Calling) Identity Delivery.
With ST - BUS and MVIP - BUS BUS, can achieve barrier-free surveillance.
Card with a processor and large capacity, no additional CunZhuQi occupy host resources.
The driver using event-driven structure, convenient multi-channel programming.
