VN-PCI series digital trunk voice card

  Function

1. Support PCI 3.3V/5V

2. Provide 1E1/2E1/4E1/8E1 (PCM) Digital Trunk Interface

3. Signaling Processing

Adopt loadable signaling processing module, no need extra card, no need changing hardware when signaling upgrades, it supports:

SS1, provides MFC TX/RX and SS1 interface

DSS1, also called ISDN, PRI

SS7, provides MTP, TUP and ISUP interface, completes multi SS7 processing

4. Links

Support 1 to 8 signaling links warmbackup, rearrange and change back. SS7 selects freely among 1to 31 time slots, not confined by the 16^th time slot.

5. Voice Processing

30/60/120/240 channels trunk processing capability

30/60/120/240 channels of DTMF/FSK date TX/RX

Recording,, compression and voice playback

support A-law/u-law voice CODEC; ADPCM/GSM6.1 PCM compression

Adopt distributed teleconference technique, realize any IVR teleconference without an extra teleconference card.

support CSP, barge in

support ASR, TTS

6. H.110 CT-Bus connects with any third card that supports this specification, transfers acquired voice signal to other equipments

7. Detect single/dual tones of any frequency. Use with all types of switch and group telephone

8. 32-128ms echo cancel function. Use advanced DT/ EPC algorithm largely increase sound quality and meeting effect.

9. Supported OS:WINDOWS2000/NT/XP/2003

                       LINUX kernel 2.6/2.4 support Asterisk

   Feature

1.Unified Vcard Drive Software

    Vcard voice card owns intellectual property rights for the high unified driver development platform. The complex call procedures can be analyzed and controlled through simple function call on the driver platform, without having to understand details. It automatically completes the whole process of digital trunk out-dialing call, and rightly recognizes the called party.

2.Unique Hardware Serial Number

   The on-board authorization code identification circuit is designed for software safety. A unique Vcard hardware serial number written in firmware to distinguish it from different cards and prevent piracy. The number is available via an easy function call with applications. Users can apply unique authorization code to protect the safety of software.

3.1000MIPS high performance DSP process capability

4.Level 4 Standard Lightning Resistance Circuit
