You are bidding one one Dialogic D41h ISA board. This item has been used but is in great working condition.
The four-line D/41H board and its two-line version, the D/21H board, are ideal for applications that need high-performance voice processing but don't require the large-scale system sophistication of SCbus or CT Bus based products. The D/21H and D/41H boards use the same Dialogic application programming interface (API) as their predecessors, making it easy to scale existing applications upward to take advantage of the power and features of these boards. The D/21H and D/41H boards also have improved voice quality and automatic gain control (AGC) over the legacy D/21D and D/41D boards. Even the weakest of telephone signals traveling over difficult telephone lines can be recorded and played back with complete clarity. The D/21H and D/41H boards use the latest digital signal processor (DSP) voice processing technology, making them ideal for small- and medium-sized, server-based computer telephony (CT) systems - particularly under the Windows operating systems. Windows support includes TAPI and WAVE APIs, which facilitate call control, recording, and playback of voice messages under the Microsoft Windows Open Services Architecture (WOSA). The D/21H and D/41H voice processing boards give Windows 95 and Windows NT application developers a powerful platform for creating sophisticated interactive voice response (IVR) applications. The "H Series" boards also support use in MS-DOS , OS/2 , and UNIX operating system environments.
