Intel Dialogic D 42-NS - Voice interface card - plug-in card - ISA / 4 analog port(s)
The D/42-NS board can access called number identification for calls transferred from within the Key System Unit (KSU), access trunk identification for calls originating outside the KSU, and control message waiting indicators for message notification. The D/42-NS board also features positive disconnect supervision to immediately detect when a caller has hung up. The D/42-NS board is based on a PBX integration platform with PCM Expansion Bus (PEB) interface enabling access to all PEB supported complementary technologies. A unique dual-processor architecture comprising a digital signal processor (DSP) and a general purpose microprocessor handles all telephony signaling and performs DTMF (touch tone) and audio/voice signal processing tasks. When used with the Norstar KSU, the D/42-NS board provides a flexible platform for developing integrated computer telephony applications. Developers can integrate current applications on the D/42-NS board with minimal software modifications and create more efficient applications for the Norstar KSU by offering value-added features. The D/42-NS board is an excellent building block for expanding the capabilities of voice processing applications.
