Telephone Recording Card(GX08R)
1, Parallel connection&high-impedance recording module
2,Accurately judge the channel status
Detailed introduction to Phone audio Recording Card:
Phone audio recording card(GXPCI-8R)
1, PCI interface bus, 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, Single card provides four independent collateral-operation ports for telephone recording and a port for playback
4, Supports three ways to start recording respectively for voltage-controlled, sound-controlled and key-controlled
5, Offers two selections of compression to record and play back,including 2 times (ADPCM) and 5 times, supporting playback by sound card
6, With unique tone inserting technology, it can cut in sound prompt on demand (optionally) during recording.
7, Accurately judge the channel status(Pickup/Hangup, Ringing, Activity/Silence, Short-circuit, Disconnection)
8, Supports caller ID display, and automatically identifies two modes respectively for FSK and DTMF
9, Provides caller ID detection in a wide dynamic range, resulting in Caller ID can be accurately detected in poor circuit condition
10, Configuring various functional modules in different ways results in both high-impedance recording and automatic sound response message features.
11, Drivers is based on event-driven in order to multi-channel programming
4-channel,8-channel and 16-channel recording card are based on unified sound card driver and the three cards can be mixed slot
12, Supports unique AGC in volume, which ensures the volume balance between the two sides talk and tone clear
Development Environment:
Provides drivers in WIN98/2000/XP/VISTA/7 and LINUX operating system
