The author introduces basic concepts, technologies and a standard for the network node interface (NNI) for synchronous digital networks. Basic requirements for such networks and the NNI are considered. The concepts of a nine-row-based frame structure and a virtual container, which are fundamental to NNI, are introduced. Detailed NNI structures are described. Practical applications of NNI in synchronous networks and international interworking are considered. The accommodation of the asynchronous transfer mode (ATM) is also discussed
