METHOD OF TESTING M-INFER Channel Resource in Switch

摘要

The present invention relates to an MFR channel resource test method that can test itself on an MFR channel resource (R1 / R2) made up of different inter-station signaling schemes using a country code in an exchange, Checking whether the data is in a null state; Increasing the test channel counter when the data to be transmitted is in a null state; checking the currently set test mode; When the test mode is the test mode for the DTMF data, the DTMF test data is written in the transmission buffer of the channel, and when the test mode is set to the test mode for the inter-station signal, the current country code is analyzed, Writes the test data of the channel into the transmission buffer of the corresponding channel; If the data to be transmitted is not in the null state, it is checked whether the test mode of the current channel mode is the test mode for the resource, and if the DTMF test mode is selected, the DTMF data is tested by the loopback method, And performing a test for an inter-station signal by a loop-back method when the test mode is for a signal.
