IPC: H04N1/00
Filed: 1998-12-31
Abstract: PURPOSE: A method for controlling facsimile data transmission is provided to enable data transmission using DMA(direct memory access) without auxiliary logics. CONSTITUTION: A method for controlling facsimile data transmission includes first thru third steps. At the first step, a DMA request(DMA RQ) signal is input from a peripheral device(200) requesting data transmission based on DMA method. At the second step, An acknowledgement signal(ACK) responding to the DMA RQ signal is transmitted to the peripheral device(200). At the third step, a quasi address is generated so as to block chip select signal from being supplied when the stored data is read from a data memory(14).

Filed: 1999-08-11
Abstract: 본 발명은 전화기 자동 다이얼에 관한 것으로, 종래의 다이얼러보다 진일보한 단축단말기이다.특히 종래의 단축단말기는 일정한 프로그램에 의해서 동작되는 것이 아니라 사용자의 연결된 전화기의 수화기를 들면 자동으로 단축단말기에서 이미 입력된 번호를 송출하는 방식을 택하여 사용하고 있지만, KD-2000은 전화사용자가 전화기의 착신번호를 입력하면 KD-200O CPU IC에서 사용자의 번호를 분석하여 단말기에 입력된 번호를 송출, 통신사입자를 선택 통화를 할 수 있게 하는 방식의 단축단말기이다. 특히 KD-2000은 한국통신의 선불카드용 단축단말기이며,  사용자에게 편리성을 제공하기 위해 선불카드의 번호를 교체시에 원격 프로그램으로 입력이 가능하도록하는 방식을 도입했다.  또한 한국통신의 선불카드 접속번호는 마스킹되어 있고 카드번호 및 지역번호는 원하는 번호로 항상 프로그램 할 수 있으며 대기시간 및 접속시간 역시 1∼9초까지 조정이 가능하여 교환대 사양이 바뀌더라도 KD-2000 단말기는 반영구적으로 사용이 가능하다.

Abstract: PURPOSE: A cellular phone, an attachment for the same, and a system using the same, are provided to simplify drawing in/out of digital money, to improve operation, to be capable of paying at once within a scope accounted in a finance institution, to improve portability and human interface. CONSTITUTION: In a cellular phone, an attachment for the same, and a system using the same, the cellular phone includes a remote communication device(2), a local communication device(27), a data/information input unit, a data/information memory(25), a displayer, an encoder, code demodulator, and a controller. The remote communication device(2) enables to communicate with a remote terminal wirelessly. The local communication device(27) enables to communicate with a local terminal wirelessly. The data/information memory(25) maintains data or information. The encoder encodes transmission data. The code demodulator reads codes of the transmission data.
