New features of 9.6LIN SU3 are:

  • Support for the Linux Kernel 3.10 
  • Included Diva SDK 5.5LIN SU 5 runtime libraries
  • Upgraded Dialogic DSI SS7 Software Development Package (DPK) to version 6.6.11

System Release 9.6LIN SU2 brings in core Software required for certain affected Dialogic Diva PCIe Media Boards, due to an application-specific integrated circuit (ASIC) replaced by a field-programmable gate array (FPGA).

System Release 9.6LIN and SU1 combined allow up to eight (8) Dialogic Diva Media Boards to be installed on a computer running the Linux operating system distributions SuSE, Red Hat, Debian or generic Linux distributions as 32 or 64 bit variant. It supports unified messaging, voice, speech, conferencing applications, RAS & RRAS (client and server mode), modem and fax as well as Voice over IP (VoIP) and Fax over IP (FoIP).

The features of System Release 9.6LIN and SU1 are:

  • Support for the latest Linux Kernel 3.2
  • New SIPcontrol version 2.1.5
  • New softIP version 2.4
  • DSP enhancements for G.722 (bit order and DTMF processing) and LPCM
  • DSP enhancements for short burst tone detection used by alarm equipment
  • Increased Fax stability for V-xPRI Boards
  • Included Diva SDK 5.5LIN SU 4 runtime libraries
  • New features for Asterisk (version 1.6 and 1.8) using chan_capi
  • Support for new HD Audio Codecs (G.722/ISDN, G.722.1) using the V-xPRI Media Boards.
  • Support for HD Audio IP Conferencing using the chan_capi command "resource" (see also readme.diva.HDAudio).
  • VIDI Interface for Analog Boards providing an increased performance.
  • A new WEB based Line Test tool

    • Dialogic Blue FourSpan-96/120-H-HL Telephony Board 
    • Dialogic Blue EightSpan-192/240-H-HL Telephony Board

    The new boards mentioned above are equipped with an echo canceller chip for VoIP applications like Asterisk and SIPcontrol. The protocol and media stack software (except echo cancellation) runs on the PC host; the maximal channel density depends on the PC host performance. The Blue-H Board types provide support for all international E1/T1 protocols as offered with E1/T1 Diva Media Boards.
    The media stack includes the features sRTP, RTP/RTCP, G.711 Codec (a/ulaw) including CNG and VAD, AGC for conferencing, G.168 Echo Canceller (128 ms echo tail per chip), anti jitter buffer, Line Interconnect (cross board switching and conferencing, Fax tone detection and DTMF detection, full duplex barge-in.
