    Abstract: PURPOSE: An SAR(Segmentation and Reassembly) device of an AAL2 type ATM cell is provided to reduce performance deterioration of a microprocessor caused when controlling an SAR function of an AAL2 type ATM cell, thereby being applicable to any place using a different AAL2 type ATM cell. CONSTITUTION: The first inner memory(103) stores a perfect short cell payload. The first CAM(Content Addressable Memory)(102) stores a mapping table, searches a stored position of the first inner memory(103), which corresponds to identification information of an inputted short cell, and supplies the searched position. The second inner memory(105) stores an imperfect short cell payload. The second CAM(104) records stored position information of the second inner memory(105) corresponding to identification information of an imperfect short cell. A short cell separator(106) receives an AAL2 type ATM cell to separate into a short cell, and perceives whether the separated short cell is perfect. If so, the separator(106) stores the payload of the short cell in the first inner memory(103). If the short cell is imperfect, the position of the short cell is recorded in the second CAM(104). The separator(106) informs a CPU(200) of the short cell to be outputted. A transmission interface(108) outputs the short cell.

    Abstract: PURPOSE: A call processing apparatus using a multiplexing/demultiplexing device of an ATM(Asynchronous Transfer Mode) cell is provided to efficiently transmit data because data transmission capability is changed according to the states of a plurality of call control processors when multiplexing and demultiplexing operations are achieved, by dynamically varying weight values of the call control processors according to call throughput. CONSTITUTION: A plurality of call control processors(22) dynamically vary weight values for changing a data processing speed, according to call throughput, and process transmitted call request. A multiplexing/demultiplexing unit(23) multiplexes or demultiplexes an ATM cell with respect to the call request provided through the call control processors(22), and transmits the multiplexed or demultiplexed ATM cell. The multiplexing/demultiplexing unit(23) checks a priority bit of the ATM cell, and successively transmits the demultiplexed ATM cell to the corresponding call control processor from an ATM cell with a high priority.

An ATM UTOPIA mating unit(220) enables the UTOPIA switch transmitter(212) and the UTOPIA switch receiver(217) to perform a multiplexing or demultiplexing operation and has a transfer rate of 155Mbps. A memory unit(219) includes a flash ROM used for booting the controller(218), an SDRAM used for executing a program, and an SRAM used for channel mapping, a connection table and a buffer descriptor. An Ethernet mating unit(221) sets a communication path to the inside or the outside. A serial communication mating unit(222) executes a debugging operation.
