First, the controller 140 in the DSLAM system receives a virtual channel setting command from an operator through an operator terminal (not shown) and configures a corresponding connection information configuration table (S11).

Thereafter, the plurality of collecting units 110 in the DSLAM system determines whether subscriber data has been input from a plurality of subscribers (S12).

At this time, if the subscriber data is not input in the twelfth step (S12), the process proceeds to the twelfth step (S12), and if the subscriber data is input, the corresponding concentrator part in which the subscriber data is input among the plurality of concentrators (110). 110 determines whether there is a connection information configuration table from the controller 140 (S13).

Subsequently, if there is no subscriber data connection information configuration table in the thirteenth step (S13), the process proceeds to the thirteenth step (S13), and if there is a subscriber data connection information configuration table, the corresponding one of the plurality of collection units 110 is present. 110 determines whether the virtual channel connected through the bus is the RAS 120 or the connection to the transmitter 130 (S14).

Then, if the virtual channel is connected to the RAS 120 in the fourteenth step (S14), the RAS 120 performs subscriber access confirmation and authentication and provides an internet access service (S15).

In this case, the detailed operation process of the fifteenth step S15 will be described in more detail with reference to FIG. 3 as follows.

First, the RAS 120 assigns an IP (Internet Protocol; IP) address to a subscriber and performs a subscriber access confirmation and authentication process (S15-1).

Thereafter, the RAS 120 connects the corresponding concentrator 110 which outputs the subscriber data with the Internet network 1 on the external network to provide an Internet access service to the subscriber (S15-2).

Subsequently, the RAS 120 periodically determines whether or not the subscriber is connected to the Internet network 1 on the external network (S15-3).

At this time, if the subscriber is connected to the Internet network 1 in step 15-3 (S15-3), the process proceeds to step 15-2 (S15-2) to continuously provide an internet access service, If the Internet network 1 and the subscriber are not connected, the RAS 120 releases the subscriber connection (S15-4).

On the other hand, if the virtual channel is connected to the transmitter 130 in the fourteenth step (S14), the transmitter 130 is a subscriber via the bus from the corresponding collector 110 of the plurality of collectors 110 Upon receiving the data, the subscriber data is output to the external RAS 2 on the external network (S16).

On the other hand, the subscriber remote access method in the DSLM system according to the second embodiment of the present invention using the subscriber remote access device in the DSLM system according to the second embodiment of the present invention will be described.

First, the controller 250 in the DSLAM system receives a virtual channel setting command from an operator through an operator terminal (not shown) and configures a corresponding connection information configuration table (S21).

Thereafter, the plurality of first concentrators 230 in the DSLAM system determine whether subscriber data is input from a plurality of subscribers (S22).

In this case, if the subscriber data is not input in the twenty-second step (S22), the process proceeds to the twenty-second step (S22), and when the subscriber data is input, corresponding subscriber data is input from the plurality of first concentrators 230. The collecting unit 230 determines whether there is a connection information configuration table from the control unit 250 (S23).

Subsequently, if there is no subscriber data connection information configuration table in the twenty-third step (S23), the process proceeds to the twenty-third step (S23), and if there is a subscriber data connection information configuration table, a corresponding one of the plurality of first concentrators 230 exists. The concentrator 230 outputs subscriber data to the RAS 210 through the virtual channel set in the first bus 260 (S24).

Then, the RAS 210 receives subscriber data from the corresponding concentrator 230 and simultaneously performs subscriber access confirmation and authentication (S25).

In this case, the detailed operation process of the 25 th step S25 will be described in more detail with reference to FIG. 6 as follows.

First, the RAS 210 assigns an IP address to a subscriber and simultaneously performs a subscriber access confirmation and authentication process (S25-1).

Thereafter, the RAS 210 provides the Internet access service by connecting the corresponding aggregation unit 230 which outputs subscriber data to the Internet network 1 on the external network (S25-2).

Subsequently, the RAS 210 determines whether or not the subscriber is connected to the Internet network 1 on the external network (S25-3).

At this time, if the subscriber is connected to the Internet network 1 in step 25-3 (S25-3), the process proceeds to step 25-2 (S25-2) and continues to provide an internet access service, If the subscriber is not connected to the Internet network 1, the RAS 210 releases the subscriber connection (S25-4).

At the same time as performing the twenty-first step S21, the plurality of second concentrators 240 in the DSLAM system determines whether subscriber data has been input from a plurality of subscribers (S26).

In this case, if the subscriber data is not input in the 26th step S26, the process proceeds to the 26th step S26, and when the subscriber data is input, the subscriber data is input from the plurality of second concentrators 240. The collecting unit 240 determines whether there is a connection information configuration table from the control unit 250 (S27).

Then, if there is no subscriber data connection information configuration table in the 27th step (S27), the flow proceeds to the 27th step (S27), and if there is a subscriber data connection information configuration table, among the plurality of second concentrators 240 The concentrator 240 outputs subscriber data to the transmitter 220 through the virtual channel set in the second bus 270 (S28).

Then, the transmitter 220 receives the subscriber data from the concentrator 240 and outputs the subscriber data to the external RAS 2 on the external network (S29).

As described above, according to the subscriber remote access apparatus and method in the DSLAM system according to the present invention, the subscriber's Internet access service is provided in the DSLAM system by mounting a RAS providing the subscriber remote access service in the DSLAM system. In addition to securing the Internet access service of subscribers by making it possible, the Internet access service can be increased, thereby providing high speed Internet access service to users and the cost of equipment installation and maintenance in the operator's job. There is an excellent effect that this can be reduced.

In addition, according to the operator's settings, it is possible to aggregate some or all of the subscriber data to be transmitted to the external RAS installed separately on the external network, thereby maintaining an excellent compatibility with the existing network configuration.
