1. A telecommunication system comprising:
- a Local Area Network (LAN);
an Asynchronous Transmission Mode (ATM) network; and
a Broadband Data Service (BDS) network connecting the LAN and the ATM network and including at least one BDS server configured to perform a connectionless service function to transmit cells between the LAN and the ATM network without reconfiguring a protocol data unit of a cell in the BDS network,wherein transmission of information in the BDS network is in streaming mode while BDS users work in a message mode.

Abstract
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.
