PURPOSE: A full electronic exchanger for accommodating ADSL subscribers is provided to integrate a maintenance and repairing to one system by constructing an ADSL subscriber service form as a sub-system of an exchanger and remarkably improve an economic aspect of a service provider by having a large capacity system. CONSTITUTION: CSS(110), INS(120), ASS-T(130), and ASS-S(140) perform the same function as those elements provided in a general full electronic exchanger and are installed to process a call of a general phone subscribers and provide various additive service. ASS-A(150) is additionally installed to accommodated ADSL subscribers. The ASS-A(150) includes a DSLI for performing an interface function of a subscriber and handling an interface function to an upper multiplexing block, a TSL for performing a voice call connection function of a sub-system, an MSCI (management Service Component Interface) for providing a path for control data for controlling an exchanger and a call processing data, a DMDI for interfacing with a multiplexing link of a subscriber itself and having an interface function with an ATM access network, and an MP/TP(Message Processor/Telephony Processor) having a control function of the sub-system, thereby performing a call processing of an ADSL subscriber. That is, the ASS-A(150) includes the DSLI block for processing a voice data and an ADSL data and the DMDI block for 155M multiplexing and assembling function of the ADSL subscriber. The ASS-A(150) interfaces with the TSL block serving as the existing voice processing switch function and the control processor block.
