ProLine/2V
Feature-rich 2-port voice processing board

 

Features:

  • Two independent voice processing ports in a single, 2/3-size PC ISA slot support low- to medium-density voice systems
  • Audio connectors allow convenient off-line recording and playback of system voice prompts
  • Microphone input jack allows convenient on-line recording of system voice prompts
  • Windows® 95 and Windows NT® Telephony API (TAPI) support and .WAV audio capability
  • Caller ID capability for "screen pop" applications (supports Bellcore CLASS Protocols)
  • Optional Global DPD dial pulse detection algorithm lets you use the ProLine/2V in countries with limited touchtone telephone service
  • Voice coding at dynamically selectable data rates (24 Kb/s to 88 Kb/s, selectable on a channel-by-channel basis) provide optimal tradeoff between disk storage requirements and voice quality
  • Enhanced telephone circuitry and automatic gain control maintains recording quality over a wide dynamic range
  • Downloadable SpringWare 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

The feature-rich ProLine/2V with its compact 2/3 length, XT height footprint, is an ideal solution for small computer telephony system development. It provides two telephone line interface circuits approved for direct connection to analog loop start lines. A unique dual-processor architecture comprising a Digital Signal Processor (DSP) and a general-purpose microprocessor handles all telephony signaling and performs DTMF (touchtone) and audio/voice signal processing tasks. You can install multiple ProLine/2V boards in a single PC chassis for system expansion up to 32 ports.
