Interworking with existing network in ATM-based access network

摘要

The present invention relates to an apparatus for interworking an existing circuit public network in an ATM-based access network. The interworking apparatus according to the present invention performs signal processing for transmitting and receiving signals through a broadband ATM network, ATM network connection; A conventional line network connection unit for performing signal processing for transmitting and receiving signals through the existing circuit network, converting signals from the existing circuit network to ATM cells, and controlling signal processing and conversion; A plurality of subscriber terminals connected to a remote user to transmit / receive a signal, convert signals between the user and ATM cells, and control transmission / reception and conversion; And a system bus for transmitting signals between a plurality of subscriber terminals, an ATM network connection unit and a conventional circuit network connection unit.;According to the present invention, when an ultra high-speed information communication network is constructed based on ATM, the load on the ATM network exchanger can be reduced in interlocking with the existing network, thereby eliminating obstacles to speeding up information communication.
