<p>The realization of today's telecommunication networks is a challenging task. Network architectures are constantly  changing to meet new requirements for many new and exciting services and applications. As a result of  these added new requirements, new types and mixes of traffic profiles are being introduced into these networks.  To facilitate these needs, there are many tools which have been developed to aid in the planning, development,  optimization and traffic prediction process. One such tool is PLANITU 3.0. PLANITU is designed to handle  many types of circuit network systems and features a powerful graphics capability. The software uses wellestablished,  iterative prediction concepts, such as Erlang-B loss equation and the Wilkinson ERT method. Two  types of network systems were modeled using real data supplied by Siemens Indonesia. Target networks for study  included a fixed switched networks and a GSM (Global System for Mobile Communications) network. PLANITU  3.0 performed well for the fixed switched network systems demonstrating reasonable results within an acceptable  degree of accuracy, but performed poorly for GSM systems yielding inoperable simulation features, numerous  bugs and software instability.
