The RP series numeral relaying card uses the entire DSP structure, handling ability is formidable, lightens the main engine burden, guarantees the high density, the large capacity application system stably moves highly effective; At the same time, the DSP technology is advantageous for the software to promote, may maximum limit protect the user investment, the performance-to-price ratio is high, is advantageous for the user construction performance stably, the multi-purpose application system.  

RP series digital relaying cards contain V30/PCI, V60/PCI and V120/PCI three products.  

Single card integrates 30/60/120 group pronunciation processing, E1/2E1/4E1(PCM) digital relaying connection collection in a body, can dispose nimbly continually uses 1 signaling, the ISDN signaling agreement or 7 signaling, may directly conveniently interconnect the intercommunication with the overwhelming majority mainstream switchboard.  

Performance characteristics:  

1 Relay interface: single provision E1/2E1/4E1 (PCM) digital trunks interfaces  

2 Signaling processing 

Support signaling 1 of China (SS1)  

Support Digital Subscriber Signaling No.1 (DSS1), also known as ISDN PRI  

Support signaling 7 of China (SS7), the veneer completes many seven signaling link processing 

3 Voice processing  

The veneer has 30/60/120 group relaying channel handling ability.  

Provide 30/60/120 Road DTMF, FSK receiving and dispatching functions. The digital sound recording, the compression and playback function, the pronunciation code is A/u, the PCM compression method is ADPCM, GSM6.1.

Use the distributional teleconference technology, all channels have the independence conference resources, do not need to dispose the extra teleconference card, then realizes willfully in every way interactive teleconference.

The support continual sound processes (CSP), the comprehensive support pronunciation breaks and the echo eliminates (echo cancel) the function; Comprehensive support speech recognition (ASR) and the pronunciation synthesize (TTS).

4 May with conform to the H.100 standard homologous series resources card interconnection, may construct machine interconnects reaches as high as 4096 groups not to have the blocking direct exchange ability the multi-purpose synthesis application system.

5 the high performance DSP algorithm, the 1000MIPS DSP handling ability, guarantees the signal to be able real-time, processes accurately.

6 support Windows 98/2000/NT/ME/XP/2003 operating systems.
