DIALOG/4
Half-size 4-port voice processing board

 

Features:

  • Four independent voice processing ports in a single, half-size PC ISA slot supporting low- to medium-density voice systems
  • Dialogic downloadable signal and call processing firmware, SpringWare , facilitates feature enhancement and provides field-proven performance based on over two million installed ports
  • C language application program interfaces (APIs) for MS-DOS ®, Windows ® 95, Windows NT ®, OS/2 ®, and UNIX ® shorten your development cycle so you can get your applications to market faster
  • Application generators available from third-party providers
  • Configure multiple DIALOG/4 boards in a single PC for easy and cost effective system expansion, and to build scalable systems from 4 to 64 ports
  • Voice coding at dynamically selectable data rates, 24 Kb/s to 64 Kb/s, selectable on a channel-by-channel basis for optimal tradeoff in disk storage and voice quality
  • Enhanced telephone circuitry and automatic gain control maintains recording quality over a wide dynamic range
  • PerfectDigit(tm) DTMF (touchtone) provides reliable detection during voice playback - allows callers to "type-ahead" through menus
  • Patented outbound call progress analyzes outgoing call status quickly and accurately
  • Lifetime warranty

 

Applications:

The DIALOG/4 board, with its half-size footprint, is an ideal solution for computer telephony installations that cannot take full-size voice boards. It provides four telephone line interface circuits that are approved for direct connection to analog loop start lines. A unique dual-processor architecture, comprising a DSP (Digital Signal Processor) and a general-purpose microprocessor, handles all telephony signaling and performs DTMF (touchtone) and audio/voice signal processing tasks. Multiple DIALOG/4 boards can be installed in a single PC chassis enabling system expansion up to 64 ports.
