Dialogic D/240SC-T1 T-1 Voice Processing Board
The SingleSpan Series boards are ideal for developers seeking to provide cost- effective, highly scalable, high-density computer telephony (CT) solutions for voice processing applications that require ISDN Primary Rate service termination plus 24 (T-1) or 30 (E-1) voice ports in a single PC slot. A number of different models are available. A unique dual processor architecture comprising of digital signal processors (DSP) and general-purpose microprocessors handles all telephony signaling and performs all DTMF (touchtone) and audio/voice signal processing tasks.??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 µ-law or A-law 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.
