3) Analog Subscriber Line Board sends bell signal, and two line loop analog boards detect bell signal when ring for the first time, reports ring event to exchange main frame simultaneously;
4) exchange main frame is connected frequency shift keying signal plate with switching network;
5) exchange main frame sends instruction, the passage to be tested of frequency shift keying signal plate sends the signal of its all supports in order, now the test channel of frequency shift keying signal plate, switching network, Analog Subscriber Line Board, service cable, two line loop analog boards have formed a passage jointly, this passage is the calling number Transfer pipe under true environment, and two line loop analog boards are received in the frequency shift keying signal transmitting on circuit;
6) two line loop analog boards detect ring for the second time, and the frequency shift keying signal receiving is reported to exchange main frame, and exchange main frame sends halt instruction, and frequency shift keying signal plate and switching network are disconnected, and called subscriber are sent and are released order simultaneously;
7) signal that exchange main frame sends the signal receiving and frequency shift keying signal plate contrasts, and according to signal, whether unanimously determines the test channel quality of frequency shift keying signal plate, and by information at screen display.
The present invention has following beneficial effect with respect to prior art:
(1) mutual by message between exchange main frame and frequency shift keying signal plate of the present invention, the operating state that can test accurately each single board communication unit.
(2) the present invention's transmission at switching network and subscriber cable by frequency shift keying signal, the real work situation that can test accurately frequency shift keying signal.
(3) the present invention, in conjunction with the process of call, can test the situation of the actual use of frequency shift keying signal veneer accurately.
(4) frequency shift keying signal board test device of the present invention can be tested polylith frequency shift keying signal plate simultaneously, and testing efficiency is high.
