Access network based on the Internet Protocol

摘要

A distributed access network (100) includes a master node (120) and a plurality of slave nodes (110) connected to the master node (120) through a network (140) such as an existing LAN. At the opposite ends of the access network (100), communication of communication data of a subscriber terminal (130) is performed by the V5 interface, and in order to allow the communication data to be communicated through the existing LAN in the inside of the access network (100), each of the master node (120) and the slave nodes (110) converts the communication data from the V5 interface into an IP packet or from an IP packet into the V5 interface. <IMAGE>
