METHOD FOR TRACKING V 5.2 ANALOG SUBSCRIBER CALL

摘要

PURPOSE: A method for tracking a V 5.2 analog subscriber call is provided to track a connection state changing of a time slot in a time switch when trying a V 5.2 analog subscriber call under control of a subscriber call tracking function of a high-capacity full electronic exchange to stabilize a system through control of an operator and maintain a program. CONSTITUTION: A call trace registration flag of a relative time slot is set up only for a call trace registration line when trying a V 5.2 analog subscriber call. A result of a line state is output by checking the call trace registration flag according to a call trace. A connection state changing of a time switch generating during processing of a relative call is output by setting up the call trace registration flag, when a bearer channel is allocated. When the V 5.2 analog subscriber call exits, the call trace registration flag is reset up.
