A BROAD-NARROW BAND INTEGRATED BOARD AND METHOD FOR TESTING SAID BOARD

摘要

A broad-narrow band integrated board includes: testing bus, for connecting the traffic signal to the testing device; switching unit matrix, for switching on the testing bus and the subscriber line, to make the traffic signal to be tested access into the testing bus, and at the same time establish the no-tested traffic channel. A method for testing the broad-narrow band integrated board includes: setting the testing bus and the switching unit matrix at the broad-narrow band integrated board; on-demand the switching unit matrix selecting the connect testing bus and subscriber line, to make the traffic signal to be tested into the testing bus, and at the same time establish the no-tested traffic channel; and testing the signal to be tested through the testing bus. It can carry a general test on the broad-narrow band integrated board through adopting the technical scheme in this invention; simultaneously it would not affect other signals when testing a signal.
