METHOD FOR PROCESSING CUT-OFF CALL IN ADVANCED SPACE SWITCH IN WIRED TYPE SWITCH

摘要

PURPOSE: A method for processing a cut-off call at an advanced space switch in a wired type switch is provided for quickly recovering a cut-off call error with an operator by displaying a cut-off call error occurrence message and a section in which the error occurs. CONSTITUTION: When a call is started, an ASP(100) outputs a space switch connection request signal to a SNC(420) for performing a call processing operation. The SNC(420) receives a space switch connection request signal output from the ASP(100), searches an idle state from its table and outputs a state information with respect to a corresponding channel of the idle state to the LSC(510). The SLC(510) receives a state information with respect to a corresponding channel of the idle state output from the SNC(420) and judges whether the state information with respect to a corresponding channel of the idle state from the SNC(420) is the same as the state information with respect to the channel stored in the image table.
