D/240SC-T1

24-Port voice processing and T-1 ISDN PRI board

Features:

  • High channel-per-slot density: one T-1 ISDN span plus 24 channels of voice processing per ISA slot enable system integrators and developers to lower costs by incorporating more ports per chassis, by using less expensive desktop-style machines, and by easing configuration/installation effort
  • Create more cost effective switching solutions via access to the SCSA SCbus with its 1024 time slot capacity; provides the capability to build higher density systems and large, multinode systems through SCxbus interbox communications
  • Compatibility with PEB systems enables dropping D/240SC-T1 boards into existing Dialogic based applications with little or no application modification and gives you an immediate increase in system density while maintaining compatibility with a wide base of existing applications and hardware products, such as TTS, SIVR
  • 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
  • Three independent Motorola DSP56002 Digital Signal Processors, clocked at 66 MHz, each with private, high-speed SRAM, permit execution of high performance SpringWare signal processing algorithms
  • Two Intel 486 GX microprocessors offload call processing tasks from host PC, giving more power to the application
  • Board Locator Technology eliminates confusing dip switch or jumper settings and simplifies installation
  • C language application program interfaces (APIs) for MS-DOS®, UNIX®, 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 best computing platform that fits your needs
  • Supports ISDN Primary Rate (see ISDN-PRI Support section)

Applications:

  • Voice messaging
  • Interactive voice response
  • Debit card and international call back
  • Audiotex
  • Operator services
  • Telemarketing/call center
  • Dictation
  • Auto dialers
  • Notification systems
  • On-line data entry/query

 

The D/240SC-T1 board provides T-1/DSX-1 ISDN Primary Rate service termination and call processing for up to 24 voice channels in a single PC slot.

A unique dual-processor 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/240SC-T1 board, as a member of the DIALOG/HD High Density series of products, is based upon Signal Computing System Architecture (SCSA). SCSA provides an open architecture that 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.
