All known techniques for handling complex problems successfully seem to fall into one of t

he three classes: subdividing the problem(51), ignoring irrelevant detail in a safe way(52), and having an independent agent(53)the internal consistency(contextual checking). The first two provide guidelines for solving the problem, the third serves to provide early warnings. A good programming language supports all three.In subdividing problem, some of the subproblems may be similar to the(54) problem. It leads us to a(55)solution. This(55)solution is viable provided each of the subproblems is easier to solve than the original problem.

VOIP gateways are designed to convert voice from the(69)domain to the circuit switched domain. VOIP solutions use a digital signal processor(DSP)to process the voice data, preparing the voice sample for transmission by compressing voice and removing jitter. The VOIP equipment must comply with the(70)H.323 standard defined by the International Telecommunication Union, or ITU.
