Abstract
The invention is to provide an STM-16 Network-Node Interface(NNI) which is capable of exactly checking whether a fault is generated on any station when the VC-4 AU received from a remotely located station has the fault, by checking the incoming data streams and communication with the remote node using the still unused values of APS bytes, thereby further enhancing the reliability thereof, which comprising duplicate physical layer processing blocks for processing a physical layer to provide a plurality of simplex ATM layers, and an ATM layer controller for controlling the processing condition of each of the ATM layers processed by the ATM layer processing means, to thereby processed information to the microprocessor; and ATM layer processing block for processing the ATM layers to a plurality of ATM cells.
