Features:

1, PCI bus interface, plug and play, whole based on DSP architecture

2, Parallel connection and high-impedance recording module, rules out interruption of data transmission on monitored channel at any time

3, Offers two selections of compression to record and play back, including at 2 times (ADPCM) and 5 times(GSM), supporting playback by sound card

4, With unique tone inserting technology, it can cut in sound prompt on demand (optionally) during recording.

5, Accurately judge the channel status(Pickup/Hangup, Ringing, Activity/Silence, Short circuit, Disconnection)

6, Supports caller ID display, and automatically identifies two modes respectively for FSK and DTMF

7, Configuring various functional modules in different ways results in high-impedance recording , automatic sound response and leaving message.

8, Single card supports 4/8/*6 channels processing and single host computer supports **8 channels processing, which do no need for inter- card connection

9, Drivers is based on event-driven in order to multi-channel programming

*0, *-channel, *-channel and **-channel recording card are based on unified sound card driver and the three cards can be mixed insertion.

*1, Supports unique AGC in volume, which ensures the volume balance between the two sides talk and tone clear

*2, Provides caller ID detection in a wide dynamic range, resulting in caller ID can be accurately detected in poor circuit conditions
