Dialogic D/42-NS Voiceboard


The D/42-NS board is based on the Dialogic PBX Integration Platform with an industry-standard 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 (touchtone) 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. Dialogic 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 Dialogic D/42-NS board is an excellent building block for expanding the capabilities of voice processing applications.

Downloaded firmware algorithms executed by the on board DSP, provide variable voice coding at 24 and 32 Kb/s ADPCM, and 48 and 64 Kb/s. Sampling rates and coding methods are selectable on a channel-by-channel basis. Applications may dynamically switch sampling rate and coding method to optimize data storage or voice quality as the need arises. These firmware algorithms also provide reliable DTMF detection, DTMF cut-through, and talk off/play off suppression over a wide variety of telephone line conditions.
