As the complexity of networks increase, the required systems include providing standard interfaces for public use among the networks. But the most of telecommunication network have been managed with network provider's own NMS (Network Management System). The Central Office Local Area Network is also managed by proprietary management protocol, which has no compatibility with other network management protocols. This paper presents a gateway system for subscriber's management which provides standard interface, CORBA for information sharing and provides the adaptability between proprietary management protocols of Central Office Local Area Network. We illustrate subscriber information model and describer implementation scenario using gateway system. It enables effective information management and integrated management.
