ABSTRACT:
A fully-interconnected ATM switching apparatus comprising a plurality of line interface circuits, each of the line interface circuits including an input port driver for extracting an SDH transmission frame containing cell data with a fixed length and a connection identifier from an input signal, appending a routing tag to the extracted SDH transmission frame and outputting the resultant SDH transmission frame through an input dedicated bus and an output port driver for receiving a cell stream from an output dedicated bus, removing the routing tag from the received cell stream, translating a channel identifier in the connection identifier and transferring the resultant SDH transmission frame to an adjacent node, a system clock distributor for generating a clock signal, an initialization controller for controlling system initialization and restart operations, a switch maintenance controller for performing a switch maintenance control operation in response to a network managing cell, a switch call processing controller for performing a call processing operation, a switch module controller for controlling a switching operation, and a plurality of switch output multiplexers for switching cells from the input port drivers to the output port drivers under the control of the switch module controller.
