D/300SC-E1 75 OHM REV 2 - Dialogic

Onboard DSPs provide variable voice encoding at bit rates of 24 and 32 Kb/s for Adaptive Differential Pulse Code Modulation (ADPCM) and bit rates of 48 and 64 Kb/s for Pulse Code Modulation (PCM). 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. SpringWare™ firmware also provides reliable DTMF detection, DTMF cut-through, and talk off/play off suppression over a wide variety of telephone line conditions.
