AAL (AAL) 1 and AAL (AAL) 5 implementation using software and arbiter control unit

摘要

The present invention relates to AAL 1 and AAL 5 implementations using software and arbiter control units. It is an object of the present invention to provide an AAL 1 and AAL 5 implementer using software and an arbiter control unit that can replace AAL type 1 and AAL type 5 hardware with software and an arbiter control unit that can be used for a 155.52 Mbps ATM communication card There is.;It is an object of the present invention to provide a terminal capable of providing a broadband service in an asynchronous transfer mode (ATM) network and a multi-media An arbiter control unit for transmitting data by distinguishing an AAL type 1 which is an image and a voice data which are fixed bit rate connectivity data and an AAL5 type 5 which converts signal control data into the ATM layer in the ATM network; An interrupt service routine for distinguishing the AAL type and driving the program; This is achieved by the AAL1 and AAL5 implementations using software and arbiter control units featuring a main control routine that can process all AAL type 1 AAL type 5 with one central processing unit and manage the ATM card.
