DATA MONITORING METHOD OF A TRUNK INTERFACE CARD

摘要

PURPOSE: A data monitoring method of a trunk interface card is provided to verify an error tracking and a cause grip of a signaling data for all channels without a help of an external machine by confirming whether an error between a superior processor and a trunk interface is generated. CONSTITUTION: The data monitoring method comprises the steps of: resetting a CAS report counter for each channel and a CAS report region; comparing present received signaling data with signaling data of a corresponding channel received in a previous state; and reporting a maintainment time counter value of the signaling data for a corresponding channel recorded in the CAS report region. When the present received signaling data is identical to the signaling data of a corresponding channel received in a previous state, a counter value is increased.
