This paper describes the ATM Up-link module for the " M A S 1 , a high-performance ISDN/ATM multimedia integrated access system based on our patented single board large capacity (32Kx32K) ISDN switch network'. The module implements an ATM 155M SDH UN1 interface and employs CBR AALl SDT to adapt nx64Kbps user data. The system's signalmg interworking function is considered in particular. The paper presents the architecture and implementation scheme of the up-link module. It is important to note that this up-link module can be referred to as a general N-ISDN to B-ISDN Interworking Function (IWF) in ITU-T terminology.
