Integrated Input / Output Matching Block (IOPH) of Remote Matching Switching Unit (RASM) in Electronic Switching System

摘要

The present invention is an input / output matching block (IOPH) consisting of a block of boards having a control function (IOP) and a block of boards having an extended function (expansion IOP) for man machine communication of the remote device matching switching unit in the electronic switch. I / O matching method (IOPH) integration method of Remote Matching Switching Unit (RASM) in an electronic switch that enables the integrated mounting of a single back-plane. -Because it is composed of a plane, it is used by connecting it with a cable, there is a problem that causes a malfunction of the system if the cable itself is defective or unstable contact when connecting the connector, the present invention solves this problem of the prior art The input / output that was executed by the two back-planes by mounting the coja, the port switching access board (PSAA), and the input / output ports on the input / output matching back board (IOBB). The output matching function is directly applied to a single back-plane to reduce the size of the input / output matching block and to improve the reliability of the system by eliminating the existing cable.
