D/240PCI-T1

24-Port Voice Processing & T-1 ISDN PRI Board

Features:

  • High channel-per-slot density: one T-1 ISDN span plus 24 channels of voice processing per PCI slot enable system integrators and developers of computer telephony applications to take advantage of PCI slots in personal computers and servers
  • Create more cost-effective switching solutions via access to the SCSA SCbus with its up to 2048 time slot capacity; provides the capability to build higher density and larger systems H.100 connector allows for easy future expansion to the new industry standard CTbus
  • SCbus support enables compatibility with a wide base of existing hardware products, such as TTS and automatic speech recognition functionality
  • Dialogic SpringWare, downloadable signal and call processing firmware, 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 66 MHz Motorola DSP56002 digital signal processors, each with private, high-speed SRAM, permit execution of high-performance SpringWare signal processing algorithms
  • Two Intel 486 GX microprocessors off-load call processing tasks from host PC, giving more power to the application
  • Plug and Play ready. Simplifies installation by eliminating DIP switches and jumper settings and enabling software controlled configuration.
  • C language application program interfaces (APIs) for UNIX®, Solaris, and Windows NT® shorten your development cycle so you can get your applications to market faster
  • Configure multiple boards in a single chassis, PCI bus or mixed PCI/ISA bus, for easy and cost-effective system expansion on the best computing platform for your needs
  • Supports ISDN Primary Rate Interface(see ISDN-PRI Support section)
  • Optional, on-board Global Dial Pulse Detection (DPD) feature enables callers without touchtone phones to access applications. No additional "pulse-to-tone converter" equipment needed.

 

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