PATH TEST METHOD OF BASE STATION TRANSMISSION SYSTEM

摘要

PURPOSE: A path test method of base station transmission system is provided to test a path from a channel card to a transmission/reception control unit in the base station transmission system rapidly. CONSTITUTION: In step 200, when there is a path test request from the channel cards to the transmission/reception control unit, the test unit generates and inputs test signals to the modems equipped within the entire channel cards in step 210. The inputted signals are received to a combiner of the transmission/reception control unit through each modem and switch unit/coupler. The received signal is analyzed in step 220 and its path is checked. The test result according to the analysis is stored to a memory, the report operation of the test result is performed in step 230.
