APPARATUS FOR REPORTING ALARM OF A TRANSMISSION SYSTEM BY USING A CONTROL LOGIC, AND A METHOD FOR CONTROLLING THE SAME, CONCERNED WITH COMPENSATING AN ERROR OF A FUNCTION FALL ALARM HAPPENING WHILE ATTACHING/DETACHING A BOARD TO/FROM A BACK BOARD BY HAVING A CONTROL LOGIC WHICH GENERATING A FUNCTION FALL SIGNAL BY USING AN INNER FAIL ALARM AND AN OPEN ALARM

摘要

PURPOSE: An apparatus for reporting alarm of a transmission system by using a control logic, and a method for controlling the same are provided to remove a detection error by correcting an error of function fail alarm generated when a board is detached from a back board. CONSTITUTION: A plurality of channel cards(2A-2N) generate alarm signals, each including a function fail generation control unit(1) generating a function fail alarm signal. A back board(4) is installed to insert the plurality of channel cards(2A-2N) by using board pins(3A-3C) installed at the rear parts of the channel cards(2A-2N). The back board(4) outputs an open alarm signal inputted from each channel card to an input terminal of the function fail generation control unit(1). An alarm collecting board(5) collects and processes the open alarm signals and function fail signals transmitted from the board pins(3A-3C).
