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. |
