SHD  1-8 E1/T1/J1
Digital Multimedia Board

The SHD Series, an open-access framework, delivers developers and integrators a new level of flexibility while reducing total lifecycle costs. The SHD series is available in either PCI or cPCI form factors, and satisfies both rich media processing and digital PSTN interface needs in a wide range of voice and signaling applications.
With in-house powerful signaling processing package, SHD series products combine a variety of superior signaling capabilities and can be easily configured among CAS, ISDN and SS7 signaling to be compatible with most telephony environments worldwide. In addition, with special signaling-irrelative call handling functions, Synway's in-house unified API makes switching of different signaling systems possible, eliminating the need to modify source code and hardware circuits.
Committed to combining voice, signaling, conference and fax in a single board, SHD series adopts the latest DSP architecture with unique algorithm to differentiate SHD processing capabilities from substitutes. Building on the latest DSP architecture across the whole series, SHD delivers increased processing power, more efficient power management, and digital network interface (software selectable E1/T1 network interfaces are available to eliminate multiple hardware platforms)

Key Features
  • 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.
