D/SC Voice Series

Voice processing shared resource boards

Features:

  • 8, 16, 24 or 32 independent voice channels in a single ISA slot connect to digital network interfaces via the SCbus (16 channels in a half ISA slot also available). Build larger analog or digital computer telephony systems while reducing overall system cost by using a PC chassis.
  • Create more cost-effective switching solutions via access to the SCSA(tm) SCbus with its 1024 time slot capacity; SCxbus interbox communications provides the capability to build higher-density systems and large, multinode systems.
  • Compatibility with PEB bus allows D/SC voice products to be dropped into existing applications with little or no code modification, providing increased system density while maintaining compatibility with a wide base of existing applications and hardware products such as fax, text-to-speech, and automatic speech recognition
  • Dialogic downloadable signal and call processing firmware, SpringWare , provides easy feature enhancement and field-proven performance based on over two million installed ports
  • PerfectDigit DTMF (touchtone) provides reliable detection during voice playback - allows callers to "type-ahead" through menus
  • Independent Motorola DSP56002 Digital Signal Processors, clocked at65 MHz; each with private, high-speed SRAM, permit execution of high-performance SpringWare signal processing algorithms 486 GX Intel microprocessors off-load call processing tasks from the host PC giving more power to the application
  • Board Locator Technology eliminates confusing DIP switch or jumper settings and simplifies installation C language application programming interfaces (APIs) for MS-DOS®, UNIX ® (multiple variants), OS/2 ®, and Windows NT ®shorten your development cycle so you can get your applications to market faster
  • Configure multiple boards in a single PC (ISA bus) for easy and cost-effective system expansion on the computing platform that best fits your needs

Applications:

  • Voice messaging
  • Interactive voice response
  • Voice/audio response systems
  • Audiotex
  • Operator services
  • Telemarketing/call center
  • Wireless gateway
  • Dictation
  • Auto dialers
  • Notification systems
  • On-line data entry/query

The D/SC Series of voice processing boards provides call processing for up to 32 voice or data channels in a single PC slot (16 channels in a half PC slot also available).. A unique multiprocessor architecture comprising DSPs (digital signal processors) and general-purpose microprocessors, handles all telephony signaling and performs all DTMF (touchtone) and audio/voice signal processing tasks. The D/SC boards, as members of the DIALOG/HD High Density Family of voice products, are based upon Signal Computing System Architecture(tm) (SCSA). SCSA provides an open architecture tha enables developers to use products from multiple vendors to build a unified computer telephony solution. SCSA provides features such as distributed switching, logical addressing, and location-independent resource management. DIALOG/HD products provide the flexibility to support both SCbus-based applications or existing PCM Expansion Bus (PEB)-based applications. DIALOG/HD products are compatible with many existing PEB-based applications. A D/320SC voice board, for example, can serve as a replacement for four D/81A voice boards.
