DualSpan Series
Voice Processing and T-1/E-1 ISDN PRI boards


 

Features:

  • High channel-per-slot density: two E-1/T-1 ISDN PRI lines plus 30 or 60 channels (E-1)/24 or 48 channels (T-1) of voice processing in a single ISA slot. System integrators and developers can lower costs by incorporating more ports per chassis, by using machines with fewer slots, and by easing configuration/installation
  • Create more cost-effective switching solutions via access to the SCSA SCbus with its 1024 time slot capability; build higher density systems and large, multinode systems through SCxbus interbox communications. The SCbus also provides access to a wide variety of technologies 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 at 66 MHz, each with private, high-speed SRAM, permit execution of high-performance SpringWare signal processing algorithms
  • Intel 486GX microprocessors off-load 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 Windows NT® and UNIX® (multiple variants) 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
  • Support for worldwide ISDN Primary Rate protocols

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
  • Call logging or recording

The DualSpan Series of digital voice and network interface boards provide two E-1 or T-1 ISDN Primary Rate Interface lines of service termination and call processing for 30 or 60 voice channels (E-1 boards) or 24 or 48 channels (T-1 boards) in a single PC slot. Functionally, the DualSpan boards are equivalent to two single-span boards, such as the D/300SC-E1 or D/240SC-T1, combined into one single slot ISA board. A unique multiprocessor architecture comprising digital signal processors (DSPs) and general-purpose microprocessors handles all telephony signaling and performs all DTMF, MF and audio/voice signal processing tasks. The DualSpan boards, as members of the DIALOG/HD High Density Voice and Switching Products series, are 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.
