IPC: H04L12/56
Filed: 1997-03-25
Abstract: PURPOSE: The transmission method of a telecommunication system is provided to protect precise minicell header information and effectively maintain minicell alignment. CONSTITUTION: The asynchronous transfer mode (ATM) used in a telecommunication system is a standard protocol for transferring a telecommunication data and the data is transferred in a packet of a fixed size by the name of a ATM cell.
