Here, the reception board 8 connected to the network 7 is a device for receiving an incoming call to the receiving exchange, and the test device 9 connected to the network 7 automatically performs an emergency line test. It is a device that performs.

The call trunk 4 connected to the network 3 and the report reception trunk 6 connected to the network 7 are connected by a report line (line to be tested) 5, and are connected to the reporting exchange. The receiving exchange is connected via the notification line 5. Although not shown, a plurality of call trunks 4 and a plurality of notification reception trunks 6 are provided, and a plurality of notification lines 5 are set up between the issuing switch and the receiving switch. ing.

FIG. 2 is a relay system diagram that discloses internal blocks of the test alarm device 2 and the test device 9 shown in FIG. In FIG. 2, the test alerting device 2 includes an automatic dial sending circuit (AD), a test call signal sending circuit (TSTS), a network control circuit (TEL), a pseudo call circuit (TONE), and a re-transmission receiving circuit. (RCR), a control circuit (CONT), and a recording device (PR).

The test apparatus 9 includes a test call signal receiving circuit (TSTR), a pseudo call circuit (TONE), a retransmission / transmission circuit (RCS), and a control circuit (CONT).

The operation of the present invention will be described below. FIG. 3 is a sequence diagram showing the operation of the present invention. In FIG.
First, the automatic dial sending circuit (AD) automatically sends a dial signal corresponding to the emergency notification line according to an instruction of the control circuit (CONT) of the test alerting device 2 periodically or at a predetermined time (S301). . Then, the dial signal is transmitted to the network 3 via the network control circuit (TEL). The network 3 captures the call trunk 4 based on the dial signal, and receives the call via the report line 5 to the report reception trunk 6 of the receiving exchange.

Next, the report reception trunk 6 first makes the test apparatus 9 receive a call and automatically answers it. That is, the test call signal receiving circuit (TSTR) automatically responds to the incoming call under the control of the control circuit (CONT) of the test apparatus 9 (S302). Then, the test alerting device 2 responds to the response from the receiving exchange to a test call signal (for example, P
B signal "B") is transmitted from the test call signal transmission circuit (TSTS) under the control of the control circuit (CONT) (S
303).

In the test apparatus 9, when the test call signal is received by the test call signal receiving circuit (TSTR) via the network 3, the communication trunk 4, the notification line 5, the notification reception trunk 6, and the network 7, the control circuit ( CONT) to recognize that the test call has been received. Then, when the test call reception is recognized, the pseudo call circuit (TONE) is connected to the report reception trunk 6 (report line 5), and the pseudo call circuit (TONE) of the test alerting device 2 performs the pseudo call. And test the normality of the notification line 5 (S3
04, S305), and then a retransmission test is performed. In the retransmission test, a request signal for a retransmission test is sent from the pseudo communication circuit (TONE) of the test alerting device 2 to the pseudo communication circuit (T
ONE) (S306), and the test alerting device 2 controls the network control circuit (TEL) to temporarily
The on-hook state is set (S307).

Thereafter, the retransmission transmission circuit (RC
Retransmission is performed from S) (S308), and the test alerting device 2 receives a calling signal (IR) (S309). Then
By the control of the control circuit (CONT) of the test alerting device 2,
The retransmission receiving circuit (RCR) responds to this, and returns a response signal to the retransmission transmission circuit (RCS) of the test apparatus 9 (S31).
0).

When the test is performed normally, the test apparatus 9 disconnects the test call (S311), and ends the processing (S312). In addition, the control device (CO
NT) records the test result in the recording device (PR) and outputs the test result. That is, although not shown, after a series of tests is completed, the test device 9 sends the test contents and the result to the test alerting device 2 and records them.

On the other hand, even if the calling side is a call from a normal telephone terminal device such as the telephone terminal device 1, it is connected to the test device 9 in the above-described sequence. However, the telephone terminal device 1 receives a test call signal (for example, P
The test call signal receiving circuit (TSTR) cannot receive the test call signal within a prescribed time because it does not have a function of transmitting the “B” of the B signal). Therefore, the control circuit (CONT) of the test apparatus 9 recognizes the timeout and determines that the call is a normal emergency call, and requests the network 7 to switch the connection of the incoming call to the reception board 8. Then
The network 7 transfers the incoming call of the emergency report from the telephone terminal device 1 to the reception desk, whereby the emergency report can be performed as before.

[0020]

As described above, according to the present invention, it is possible to perform an automatic test of the notification line, and it is possible to make the issuing switch and the receiving switch unmanned.

In addition, an incoming call to the reception desk of the receiving exchange is
Since all calls are received by emergency notification, the effect that the receptionist can quickly take subsequent actions can be obtained.
