The Intel Dialogic D/41JCT-LS combined media board is a four-port analog converged communications board used for developing global enterprise applications such as unified messaging. interactive voice response (IVR). and contact centers. The D/41JCT-LS supports voice. fax. and softwarebased speech recognition processing in a single PCI slot. providing four analog telephone interface circuits for direct connection to analog loop start lines.
Downloaded Springware firmware algorithms. executed by the onboard digital signal processor (DSP). provide variable voice coding at 24 Kb/s and 32 Kb/s adaptive differential pulse code modulation (ADPCM). and 48 Kb/s and 64 Kb/s µ-law or A-law pulse code modulation (PCM). as well as µ-law to A-law conversion. Sampling rates and coding methods are selectable on a channel-by-channel basis. Applications can dynamically switch sampling rate and coding method to optimize data storage or voice quality as the need arises.
