摘要 |
An integrated communication system for voice and data connecting an Ethernet LAN to an external communication network by utilizing a conventional communication system. An interface connected to the Ethernet LAN and transferring a voice signal at a data link level without processors is stored in a personal computer. An ISDN voice interface for connecting the personal computer to the external communication network with a voice channel is connected to the LAN. The input/output data of the ISDN voice interface and various routers performing data communication on the LAN is multiplexed/demultiplexed in a plurality of channels by an ADSL multiplexer. The input/output data of the multiplexer is connected to the external communication network through an access network having a user interface. |
