1 is a block diagram illustrating a method of a DSL service method of a DSL network according to an embodiment of the present invention. The DSL network according to an embodiment of the present invention is a subscriber-side DSL (Digital Subscriber Line; DSL). Modem 101, subscriber side local telephone station DSLAM (Digital Subscriber Line Access Multiplex; DSLAM) modem 102, subscriber side local asynchronous transfer mode (ATM) exchange switch 103 ), The subscriber side local voice G / W (GateWay) 104, the subscriber side local service provider equipment (SPE) (105), the subscriber side local public switched telephone network (PSTN). 106), an ATM in the other region 107, a voice G / W 108 in another region, an SPE 109 in another region, and a PSTN 110 in another region.

The subscriber DSL modem 101 receives a TDM signal from a telephone installed at the subscriber side, recognizes a telephone number corresponding to the TDM signal, and converts the TDM signal into an ATM signal to convert the TDM signal into an ATM signal. It serves to output to the telephone company DSLAM modem 102.

In addition, the subscriber side local telephone station DSLAM modem 102 receives an ATM signal from the subscriber side DSL modem 101 and at the same time the subscriber side local ATM switch 103 or another local ATM switch 107 corresponding to the ATM signal. It prints in).

And, the subscriber side ATM switch 103 is responsible for switching the ATM signal to the subscriber side voice voice G / W 104 when receiving the ATM signal from the subscriber side local telephone station DSLAM modem (102).

Further, the subscriber side local voice G / W 104 receives an ATM signal from the subscriber side ATM switch 103 and simultaneously converts the ATM signal into a TDM signal and converts the TDM signal into a corresponding subscriber side zone. It serves to output to the SPE (105).

The subscriber-side area SPE 105 receives a TDM signal from the subscriber-side area voice G / W 104 and simultaneously generates a ring signal corresponding thereto, and then operates the local area through the subscriber-side area PSTN 106. It performs VoDSL service as a telephone service and charges a call fee when the VoDSL service ends.
