Abstract: PURPOSE: A method for transmitting asynchronous transfer mode(ATM) adaptive layer(AAL) data in a control base station of an international mobile transfer(IMT)-2000 network system, is provided to separate base stations, signals, data, users and channel IDs according to values of virtual path identifier/virtual channel identifier(VPI/VCI) of an AAL data header, in an ATM frame/deframe board assembly(AFDA) of a BTS interface subsystem(BIS), so as to transmit ATM cell data between the base station and the control base station. CONSTITUTION: Values of virtual path identifier/virtual channel identifier(VPI/VCI) of an ATM adaptive layer(AAL) data header are recognized by receiving AAL data inputted from a base station. If the recognition results that a VCI-15 is 1 and a VCI-9 is 0, AAL5 data from a self-ATM frame/deframe board assembly(AFDA), is outputted to an ATM MUX/DEMUX board assembly(AMDA). If the VCI-15 is 0 and the VCI-9 is 0, the AAL data is recognized as AAL5 data, which is outputted to the AMDA straightly. If the VCI-15 is 0 and the VCI-9 is 1, the AAL data is recognized as AAL2 data, which is converted into AAL2' data in a time conversion block within the AFDA, while converting a VCI/CID into a VPI/VCI, to output the AAL2' data to the AMDA. And the AAL5 and the AAL2' is multiplied as 155Mbps, which is outputted to an ATM switch.

Abstract: 본 발명은 철근 연결구에 관한 것이다. 
     종래의 철근연결구는 분활편으로 된 상하몸체 사이에 철근을 협지시킨후 후렌지부에 뚫림된 통공으로 채결볼트를 끼운후 너트로 채결할수 있게 하였기 때문에 이를 사용할시는 상하몸체(1)(2)의사이에철근의 일단을 끼움한 후 후렌지부에 뚫린 통공을  일치시킨 상태에서 볼트를 기운 다음 볼트의 두부를 손에 잡고  너트를 나사 체결해야  하므로  작업성이 매우  저조한  결점이 있었던 것이다. 
     본 발명은 이상의  문제점을 해결하고자 창안한 것으로 이의  발명요지는 하부몸체(2)의 후렌지부(2')에는 상부몸체(1)의 후렌지부(1')의 통공(3)보다 작은 끼움공(4)을 형성하여 이에 볼트(5)의 상부측주면에 방사선사으로 형성된 걸림날개편(6)이 타입고정되어 하부몸체(2)와 일체로 되게한 것으로 이와 같이 일체로된 상태에서 상하몸체(1)(2)사이에 철근(8)을 끼움한후 상부몸체(1)의 후렌지부(1')에  비교적  넓게 형성된  통공(3)을  전기한 하부몸체(2)에  고정된 볼트(5)에 바로 꽂고 너트를 조으면 되므로 끼움 및 체결이 간편하여 철근의 연결 작업을 쉽게 할수 있는 것이다.
