<p>PROBLEM TO BE SOLVED: To reduce the loads of the processor of an ATM transmitter by distributing a data link terminating processing, ATM cellularization and a packet making processing. SOLUTION: A packet processing part 100 for receiving a packet from a packet network and transmitting the packet and protocol control signals to the packet network judges whether the received packet is the protocol control signal or user data, transfers it to a data link processing part 110 at the time of the protocol control signal, transfers it to an ATM cell processing part 120 by turning it to an ATM cell and attaching a header at the time of the user data and transmits the protocol control. signal transferred from the data link processing part 110 to the packet network. The data link processing part 110 terminates a data link and transfers the protocol control signal to the packet processing part 100 by attaching the header. The ATM cell processing part 120 transmits the ATM cell transferred from the packet processing part 100 to an ATM network, attaches the header to the ATM cell received from the ATM network and transfers it to the packet processing part 100.</p> |
