Field of the Invention The present invention relates to a common processor of an all-electronic exchange having a memory and line matching function. In particular, the electronic and electronic device having a memory and line matching function can increase operation and maintenance and cost efficiency by reducing hardware and improving functions of the system. It relates to a common processor of the exchange.

본 발명에서 제공하는 BPIB-E은 중앙 처리 장치와, B-버스 포트와, PIO회로호와, USART회로와, DMA회로와 버퍼와, SIO회로와, 버스 선택 및 하드웨어 신호 감시회로와, CTC와 클럭 제너레이터와, 자체 시험 회로와, 라인 정합 회로로 구성되며, 두개의 보드로 구성되었던 기능을 하드웨어 변경 및 단순호, 칩의 변경등에 의하여 한개의 보드화로 집적한 것인데, 기존과 유사한 기능을 발휘하면서 교환기 시스템이 간소화 될 수 있고 기존 메모리의 단종시 대체 범위가 넓으며 신뢰성이 높다는 장점이 있다. 또한 보드의 간소화로 전원 공급용 보드도 저렴한 가격의 보드로 대체 가능하므로 물량대비 가격의 잇점이 생긴다.The BPIB-E provided by the present invention includes a central processing unit, a B-bus port, a PIO circuit call, a USART circuit, a DMA circuit and a buffer, an SIO circuit, a bus selection and a hardware signal monitoring circuit, a CTC, It consists of clock generator, self test circuit, and line matching circuit, and functions of two boards are integrated into one board by hardware change, simple code, and chip change. The exchange system can be simplified, the replacement range of the existing memory is discontinued, and the reliability is high. In addition, the power supply board can be replaced by a low-cost board due to the simplification of the board, which brings about an advantage in price over quantity.
