Telecommunication industry purses interoperability so that service providers can deploy telecommunication systems composed of subsystems from multiple vendors. This characteristic makes it attractive to introduce the ideas of CBD into telecommunication systems. However, most efforts on CBD have concentrated on IT area and, thus, contemporary CBD researches little address the issues in telecommunications. The goal of this paper is to introduce CBD techniques into telecommunication area. In particular, we focus our attentions on how to introduce the idea of component architecture: To effectively handle the impact of changes, a component architecture must consist of highly cohesive and loosely coupled components. To support the design of architecture, we develop an interactive framework that explores numerous candidates for component architecture and evaluates them. Note that there is rarely enough time in development because of the pressure of time-to-market. By keeping developers from wasting their time on tedious work, the framework allows to concentrate their efforts on more valuable work such as the selection of component architecture and the decision of development strategy.
