PURPOSE: A call processing method of user part input interface line in intelligent peripheral is provided to process ISUP(ISDN User Part) input interface line call using ISUP input interface line call status model. CONSTITUTION: If an input interface line call processing part on standby receives IAM(Initial Address Message)(S1,S2), the input interface line call processing part stores parameters in IAM(S3) and confirms whether a continuity test parameter has been set up(S4). If the continuity test parameter has not been set up, the transition to PMM(Protocol Message Matching) response standby status is made(S5). If the continuity test parameter has been set up, time switch connection is requested(S6) and the transition to COT(Continuity Test) message standby status is made(S7). If the input interface line call processing part receives RLC(Release Complete) message(S10), REL(Release) message is transmitted(S11) and the transition to RLC message standby status is made(S12).
