DSPs set the limits for what packet-voice gear can accomplish - and those limits keep expanding.
They've been called the"Lubricant of Convergence, but it might be more appropriate to describe digital signal processors (DSPs) as the engines driving the development of combined voice-data networks. Just like other microprocessors, DSPs have been adhering to Moore's Law and now provide enough horsepower to run algorithms that packetize and compress voice with high quality [ILLUSTRATION FOR FIGURE 1 OMITTED]. As DSPs continue to improve and evolve, new features for packet-voice equipment will continue to emerge in the next few years.
The market leader in DSPs, ...
