摘要： PURPOSE: A DSLAM(DSL Access Multiplexer) and a network system using a digital subscriber line access multiplexer are provided to supply an interface for using a virtual LAN service to general subscribers regardless of a physical arrangement, and to supply a broadcast function by a network system, thereby realizing traffic distribution of an ISP switch. CONSTITUTION: An ATU-C(ADSL Terminal Unit-Central) unit(40) receives an xDSL signal when processing an up-packet, demodulates the received xDSL signal to extract an ATM cell, and modulates the ATM cell into an xDSL signal when processing a down-packet. An IP interface(50) converts the ATM cell into IP packet-type information when processing the up-packet, converts the IP packet-type information into virtual LAN IP packet-type information to add a virtual LAN ID, and receives the virtual LAN IP packet-type information when processing the down-packet. The IP interface(50) converts the received virtual LAN IP packet-type information into IP packet-type information, and converts the IP packet-type information into an ATM cell again.

摘要： PURPOSE: A system and a method for restricting use of an IP(Internet Protocol) address by virtual lines in an Internet access service using an ADSL(Asymmetric Digital Subscriber Line) are provided to prevent use of an IP address without permission by cutting off an IP address allocation request exceeding the number of IP addresses contacted through virtual line information. CONSTITUTION: User terminals(101,109) attempt access to the Internet. ADSL modems(102,110) transmit an ADSL signal to a DSLAM(Digital Subscriber Line Access Multiplexer)(104). The DSLAM(104) receives the ADSL signal through a traffic line path(103) and transmits it to an NAS(Network Access Server)(105). The NAS(105) receives DHCP(Dynamic Host Configuration Protocol) packets from user terminals(101,109) and transmits them to a DHCP server(107) through an Internet network(106). The DHCP server(107) stores virtual line information received from the user terminals(101,109), analyzes the DHCP packet received from the NAS(105), and if there is an IP address allocation request, the NAS(105) determines whether it exceeds the number of contracted IP addresses. If the IP address allocation request exceeds the number of contracted IP addresses, the DHCP server(107) allocates a private IP address. If the IP address allocation request does not exceed the number of contracted IP addresses, the DHCP server(107) allocates a corresponding IP address. An information database(108) includes subscriber line information and subscriber information, the number of allocated IP addresses, the number of contracted IP addresses, allocated IP address information, IP addresses in use or non-used IP address information.

The CSDB-E1 transmits the ATM-converted data to the PSTN(30) and downloads the subscriber data downlinked from the PSTN(30) to the Ethernet hub(21) through the CSUB. The network access part(22) executes network access with the PSTN(30) and the CSDB-E1.
摘要翻译：目的：提供一种用于构建ADSL服务网络的装置，通过删除位于ISP（国际信令点）和PSTN之间的ATM交换机并安装附加设备来轻松访问连接到PSTN的DSLAM（数字用户线接入模块）使从ISP的上行数据到ATM数据。构成：ATM数据转换部件（20）由以太网集线器（21），CSUB（集中架上行链路板），CSDB（集中架下行链路板）-E1和网络接入部分22组成。以太网集线器（21）通过以太网与ISP（10）发送和接收信息。 CSUB将通过以太网集线器（21）传输的数据转换成ATM数据，以将数据上传到PSTN（30）。 CSDB-E1将ATM转换的数据发送到PSTN（30），并通过CSUB将从PSTN（30）下行链路的用户数据下载到以太网集线器（21）。网络接入部分（22）执行与PSTN（30）和CSDB-E1的网络接入。
