〔産業上の利用分野〕
本発明は遠隔試験方式に関し、特に遠隔信号変換装置の
音声・信号チャネルを試験する遠隔試験方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote testing system, and more particularly to a remote testing system for testing the audio/signal channel of a remote signal conversion device.
従来、遠隔信号変換装置の音声・信号チャネルの試験は
遠隔局内の試験機を接続し、１チヤネル毎にこの接続を
保守者が変えながら行なっている。Conventionally, testing of audio/signal channels of a remote signal converter has been carried out by connecting a tester in a remote station, and having a maintenance person change the connection for each channel.
上述した従来の試験は直接試験機全接続して行なってい
るため、遠隔集中試験ができず、保守が不便である。The above-mentioned conventional tests are performed by directly connecting all the test machines, making remote centralized testing impossible and maintenance inconvenient.
本発明の遠隔試験方式は親局からの試験信号をライン信
号として受け、遠隔信号変換装置の音声・信号チャネル

チャネルの接続機能を確認する構成である。The remote test method of the present invention receives a test signal from a master station as a line signal, connects the audio/signal channel of the remote signal converter back and forth, simulates a normal connection, and performs the connection function of the audio/signal channel. This is the configuration to confirm.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

行なえる。The master exchange 11 has a test stand (T, 1
There is a Te8L)1 from which maintenance personnel give test instructions by operating keys. The key operation of T8TCiMh1 is read by the software of processor (UP) 2, and the time division switch start signal of network (NW) 7 is CF2.
According to instructions from the software, the control circuit (CONT) 5 sends it as a 9DTI 6 line signal to the voice/signal channel (VF/8IG-CH-A) 10, which is the trunk under test. VF/5IG-C)←When AIO receives this test signal, it closes path a with TSTTRK9. By passing test pass a, VF7SIQ-CH
- Alo connection tests can be performed. Master station CF
2 sends a start signal via C0NT5. At this signal
VF/8 IG-CH-AIO activates T8TTRK-9. Next, C0NT5 sends the selected digits. Since this selected number corresponds to TSTTRK4, this number returns to DTI6 via DTI6, VF/8IG-CH-AIQ, path a, and T8TTRK9'i. Upon receiving this, C0NT5 sends numerical information to CF2. CF2
translates all of this and connects T8T'l'RK4 and DTI6. T8TTRK4 sends a response signal. This response signal is 4°DTI6. T8TTRK9. Path a, VF/8IG-CH-A10, DTI6. T8
It is transmitted to TTRK3 and enters the response state. Next, TSTT
FLK4 sends a tone. This also reaches T8TTRK3 through the same route as the response signal and can be heard at T8TC8LI, confirming that the connection has been set up normally. T.S.
TTRK4 then sends a restoration signal to restore each device on the path. A recovery signal is also transmitted to TSTTRK3 and displayed on T8TC8L1. This indicates that the test was successfully completed. C0NT5 issues a test recovery signal via DTI6'i. VF/S IG-CH,-
AlO receives this and restores path a. VF/8
IG-CH-B10 or VF/8IG-CH-C]
0 (7) In the case 1'I, when a test start signal arrives at the corresponding through channel, a test similar to VF/5IG-OH-AIO can be performed by closing the corresponding test paths b and ci.
以上説明したように本発明によれば、ライン信号として

シ、遠隔信号変換装置の音声・信号チャネルの折シ返し
試験を遠隔制御によシ容易に行なえる。As explained above, according to the present invention, by forming a test path on the remote station side using a test signal as a line signal, loopback tests of audio/signal channels of a remote signal converter can be performed by remote control. It's very easy to do.
