DN300 1E1/PRI Digital Network Interface Boards This product is based on full DSP architecture, which delivers an open development environment, a rich set of features, built-in scalability, and increased processing power. This product provides digital network interface for computer telephony systems based on the CT Bus. Features and Benefits Supports one E1/PRI digital interfaces in a single slot for connection to the public telephone network. Supports 30 channels of voice processing. 30-port send-and-receive FSK ability. Provides reliable DTMF tone detection during voice playback and recording. DN series board’s voice format fully compatible with Intel Dialogic’s voice format. Provides variable voice coding at 24/ 32 Kb/s ADPCM (.vox), 48/64 Kb/s A-law/u-law PCM, and 48/64 Kb/s A-law/u-law/ linear waves. Efficiently manages DSP resources to minimize host overhead and maximize host processing. Implements full H.100 (CT Bus) specification with 4,096 timeslots to build higher density systems and reduce time to market. Advanced DSP-based voice, DTMF/MF, and call progress functions ensure application reliability. Supply the same API as DTI/301SC,D/300SC-E1,DTI/300SC of Intel Dialogic.
