Telecommunication system Including a local area network (LAN), an asynchronous transmission mode (ATM) network, and a broadband data service (BDS) network in which a protocol data unit is not reconfigured in the (BDS) network

摘要

The invention relates to a device for broadband data service transmission in telecommunication system. The invention aims at implementing bridges in public ATM network, by which public data communication services can be used by private, local networks LAN. The bridges make use of a connectionless data service function by means of broadband data service servers (BDS). The ATM network uses the protocol AAL5. According to the invention the transmission can by that be made without buffering. Preferably respective local network is connected via only one BDS server and the transmission in the BDS network is in streaming mode.
