Design and Implementation of Fixed-Phone Cluster System Based on Modern Communication Technology

A set of fixed-phone cluster management system was designed based on C&C08 program control unit and next generation network (NGN). C&C08 is responsible for the bottom access and transfer of the fixed-phone calls. Applying the computer telephony integration (CTI) technology we can realize the telephone call management through a computer. Using this system, fixed telephone managers can conduct limitation control for cluster management users information and implement list query of cost easily, so that managers can know the detail cost. In addition, based on the present situation of the telecom business, we designed four telecommunication services for enterprises and institutions, and added them to the fixed-phone cluster management system. For the cluster management users, they can subscribe to those services according to their needs.
