Latest DSP architecture
Compatible with PCI(X) or PCI-e interface
1~16E1/T1 Digital Trunking
1, 2, 4, 8,16E1/T1 digital interfaces in a single slot for connection to PSTN, voice processing, conferencing, FSK communications (1200 bits/s and 2400 bits/s), HDLC communication capabilities, as well as 1~16 SS7 signaling links on a single board.
Boards with cPCI interface supports high-availability for maintenance and replacement during system run time, with over 99.99％ availability in high capacity.
Built-in Voice Processing Resource
Support: A-law, u-law and IMA ADPCM format, record/playback of Windows WAV file, tone generation/reception/detection for signals, FSK receiver/transmitter, HLDC processing, adaptive echo cancellation, barge-in functionality.
Built-in conference resource in each port, support conference recording and monitoring; DTMF filtering to eliminate DTMF signal in conference, and can be configured as interactive teleconferencing without limit on the number of conferees and conferences in multiparties.
Rich DSP Resources
Efficient management of DSP resources minimizes host overhead and maximizes host processing time for applications; DSP-based voice, DTMF/MF and call process analysis ensure application reliability.
Multiple Signaling Capabilities in Single Board
International CAS, ISDN and SS7 supported: SHD supports ISDN PRI, CAS, QSIG, CORNET, MTP, TUP, ISUP, SCCP, TCAP, and include functions such as multi-DPC application, multi-link group and hot backup, changeback and changeover.
Universal port capability supports conference, fax, voice and signaling processing and built-in SHD Series functions to ensure scalability, compatibility, and high performance to leverage developer time and application investment.
In-House Unified API
Simplify system development and deployment efforts; protocol-independent open access interface for CAS, ISDN and SS7; support polling and event-driven modes, and feature-rich software development kits support Windows and Linux
16~80 channels of DSP based Group 3 FAX resources available, transmission speed up to 14400bps; support .TIF file; Fax transmission of all kinds of printable files, easily viewed and printable; Fax capability is software configurable.
Full-speed H.100/H.110 bus with 4,096 timeslots supports interoperability with other H.100/H.110 boards in open-architecture, high-capacity systems, and hierarchical switching model improves system and application scalability.
Up to 8 boards per system (PCI boards with upto 80E1 and cPCI with up to 128E1).
Supports super voice alteration: as many as 150 voice alteration effects available for your choice
All voice-alteration channels are independent to one another: each can be set separately with voice-alteration effects
A single board accommodates 8 E1/T1/J1 trunks
Supports China SS1, SS7 and ISDN connections in E1/T1 mode
Supports phone calling and voice processing
Automatic Gain Control (AGC) support in recording operation
Allows DTMF transmission and detection during voice recording or playback
Includes H.100 bus, compatible with MVIP, SC and ST buses, facilitating smooth connectivity to third-party boards with H.100 bus for the transfer of acquired voice signals to other devices
The flexible distributed conferencing system sets no limit on the number of simultaneous conferences and participants in each conference, allows monitoring and recording of the whole conference and each individual speaker
The on-board lightning-proof circuit reaches the telecom standard and surely eliminates the damage caused by lightning
Equipped with the EMI circuit, effectively preventing the electromagnetic interference
Each board has a unique hardware serial number written in the firmware to distinguish itself from other boards and prevent piracy.
The number is available via an easy function call with applications
