Abstract: PURPOSE: A device for multiplexing and demultiplexing an ATM(Asynchronous Transfer Mode) cell capable of self test is provided to enable a test of an input/output path, without an additional equipment. CONSTITUTION: A demultiplexing output port group(202) having demultiplexing output ports(TX#1-TX#n) outputs a supplied ATM(Asynchronous Transfer Mode) cell, if a VPI(Virtual Path Identifier) loaded on the supplied ATM cell is coincident with an allocated identifier. A multiplexing input port group(204) having multiplexing input ports(RX#1-RX#n) converts the VPI into a predetermined VPI, and outputs an ATM cell loading the predetermined VPI. The first transmission unit(203) provides each physical path capable of transmitting the ATM cell between the demultiplexing output ports(TX#1-TX#n) and corresponding multiplexing input ports(RX#1-RX#n). A multiplexing output unit(TX) outputs the ATM cell transmitted from the multiplexing input ports(RX#1-RX#n). A demultiplexing input unit(RX) analyzes the VPI loaded on the ATM cell transmitted from the multiplexing output unit(TX), to transmit the ATM cell to a unit having the corresponding VPI. A CPU(201) generates an ATM cell loading a VPI of a demultiplexing output port requesting a test. If an ATM cell loading a VPI identical with an identifier allocated from the demultiplexing input unit(RX) is received, the CPU(201) compares data of the generated ATM cell with data of the received ATM cell, to obtain a test result for an input/output path formed through the demultiplexing output port requesting a test.

Abstract: PURPOSE: A sensing method of refrigerant leakage is provided to take prompt action on gas leakage and to protect a compressor from refrigerant leakage by sensing and displaying the refrigerant leakage if temperature difference between sucked air and indoor heat exchanger sis lower than specific temperature. CONSTITUTION: A user pushes a start/run key through a key input unit on a control panel or a remote controller and sets operation mode, set temperature(Ts), set air flow and set flow direction of an air conditioner. A control unit drives an indoor fan and rotates a stepping motor to open vanes(7). After passage of specific time(t1), the control unit compares sucked air temperature(Tr) with the Ts. If the Tr is higher than the Ts, the control unit drives a compressor and an outdoor fan. The sucked indoor air is heat-exchanged into cold air through an indoor heat exchanger and discharged to inside trough a discharge port. After refrigerant circulating time of t2, indoor air temperature(Tr) and refrigerant pipe temperature(Tp) of the indoor heat exchanger are detected. If temperature difference(Tr-Tp) is lower than 5deg.C, the control unit counts time(t3) for sensing refrigerant leakage. After the t3, the control unit stops the compressor to stop the cooling of an air conditioner. Thereby, the compressor is protected. Finally, the control unit displays error in refrigerant leakage of the air conditioner on a display unit.
