TINA (Telecommunications Information Networking Architecture) has been developed to support efficient operation of a wide range of complex services. TINA is effective in building advanced multimedia related services and provides effective solutions for complex service control and management along with a high level of quality of services. However the benefits and effectiveness of TINA for other types of services such as ordinary telephone services and facsimile messaging services are not clear. This paper clarifies how to apply TINA to control and management of computer telephony (CT) services and ordinary telephony services. We designed and implemented CT services in a distributed processing environment (DPE), and in particular a click-to-dial service, as a target for our study. We demonstrate the effectiveness of the design through qualitative and quantitative evaluation. The results of our study show that the distributed processing technique, based on component concepts makes it easy to build and extend CT services, and also that TINA service architecture is applicable to ordinary telephony and advanced CT services.
