Hangzhou Sanhui Digital Relay Voice Card

SHD-60C-CT/PCI Hangzhou Sanhui Digital Relay Voice Card PRA/PRI/ISDN/SS7/SS1, type voice card, is a digital relay line voice card that uses the PCI bus. This series of voice cards can achieve most of the functions required for voice processing systems that use E1/T1 digital relay line access Beijing Xinhe Sichuang Technology Co., Ltd

Function description:

Single card provides 2 E1/T1 relays;

Support call connection for China's No.1 signaling, No.7 signaling (TUP, ISUP), and ISDN signaling;

Support call and voice processing functions;

Call/mute detection;

Recording operation supports automatic gain control (AGC);

Reception and transmission of FSK data;

The transmission and detection of DTMF signals can be performed simultaneously with recording and playback of audio;

Adopting CT-BUS bus, compliant with H.100 standard, it can easily interconnect and communicate with any third-party board that supports this standard, and is compatible with MVIP bus, SC and ST bus, thereby exchanging the acquired voice signals to other devices;

Adopting a flexible distributed conference structure, the number of meetings is not limited, the number of participants is not restricted, and the content of the meeting or the conversation between both parties can be recorded;

The card is equipped with lightning protection circuits that comply with telecommunications standards to ensure it is not damaged by lightning strikes;

Has a hardware serial number. The firmware on each voice card is written with a hardware serial number, which can be used to distinguish different cards and anti-counterfeiting recognition. The application system can obtain it through simple function calls;

Equipped with a hardware authorization number recognition circuit. Users can apply for authorization numbers from our company to protect the security of their software;

SHD-30/60C-CT/PCI/single card can support up to 32 channels of resources, with a maximum transmission and reception rate of 14400bps per channel.

Performance characteristics:

Supports PCI2.2 bus specification:

Compliant with PCI2.2 bus standard, supporting 3.3V/5V environment, with a burst data transfer rate of up to 132MB/s; Can be used on PCI-X slots; Supports plug and play (PNP) without any jumper settings.

1. Signal application interface: Signal 1 provides two layers of interfaces for MFC transmission and SS1 connection, while Signal 7 provides two layers of interfaces for MTP, TUP, and ISUP to meet different user needs.

2. Signaling processing function: Adopting a loadable signaling processing module, a single card supports Signal No. 1, Signal No. 7, and ISDN without the need for additional signaling cards. Signal upgrades do not require hardware replacement and can be achieved through simple software configuration.

3. Signaling Link: A single card supports up to 2 signaling links and supports hot backup, switching, and rollback functions for multiple links, greatly improving flexibility and reliability. The 7th signaling and ISDN data link can be selected from time slots 1-31 without being limited by the 16th time slot.

4. Programmable Signal Sound Detector: A programmable signal sound detector that can detect single/dual audio signal sounds of any frequency, easily compatible with various models of switches and groups.

5. Software configuration terminal matching method: The same hardware supports three impedance relays: 75 Ω E1 coaxial cable and 120 Ω E1 twisted pair cable that comply with G.703, as well as 100 Ω T1 twisted pair cable that complies with T1.403 waveform specifications. The sending and receiving terminals are configured by internal software and can be easily connected to various forms of digital relays and optical transceivers.

6. Professional driver software algorithm: The driver software adopts the professional SPECDial algorithm, which can automatically complete the entire process of unplugging the digital trunk line and correctly identify the status of the called user.

7. Echo cancellation: Echo cancellation uses adaptive algorithms to effectively cancel echoes in various usage environments, thereby eliminating the impact of playback on DTMF signal reception and busy tone detection, and eliminating the possibility of self excitation, erroneous reception of DTMF numbers and busy tones during meetings.

8. Bargein function: supports voice interruption Bargein function.

9. Supports multiple speech encoding and decoding formats: supports hardware processing of A-Law (G.711), μ - Law, IMA-ADPCM formats for encoding and decoding, as well as software processing of 16 bit LinearPCM, MP3, VOX formats for encoding and decoding, supports WINDOWS standard WAV files, and can be easily edited and played using sound tools such as Cooledit.

10. Unified Sanhui SynCTI Driver Development Platform: The unified SynCTI driver development platform with independent intellectual property rights has high intelligence. A single machine can support up to 2048 channels. The analysis and control of the call process can be easily achieved by calling the functions of the driver platform, without the need for you to know too much about the details of the call.
