ABSTRACT:
A remote maintenance ATM cell transmitted from a remote maintenance terminal is input to a channel control section of a node. An ATM cell header fast transform circuit affixes routing information indicating that a control signal transmitter/receiver section is the destination to the header portion of the remote maintenance ATM cell, and updates VPI/VCI values with values indicating a channel through which the ATM cell is transmitted. Then, the remote maintenance ATM cell is transmitted through an ATM cell switch to the control signal transmitter/receiver section. The remote maintenance ATM cell is formed into a frame there, which is transferred to a main control section. The main control section controls the individual sections of the node based on the received frame.
