CONVERGêNCIA DAS REDES DE COMUNICA？？O: ASPECTOS TéCNICOS E ECON？MICOS

the tendency in world communications is the convergence of the three traditional networks (voice network, wireless network and data network), currently provided separately, into a common packet based infrastructure. universal access and a host of new technologies, applications and services will be derived from the convergence into an intelligent and highly efficient infrastructure. this work presents information demonstrating that, in the near future, established operators, in order to keep up current revenues and to increase profitability, should add value to services. for this purpose, they should deploy the convergence in a gradual manner, taking advantage of existing assets, as well as from the scratch, fully replacing their entire tdm infrastructure.
