Abstract

PURPOSE:To simplify the connection between an exchange and a testing device at the time of testing by executing the test of pseudo call by exchanging a subscriber circuit with a pseudo call testing package. CONSTITUTION:The package provided with pseudo call testing subscriber circuits 19 and 20 is substituted for a subscriber circuit package installed in the line to be tested. A call is made by the loop information inserting circuit 9 of the outgoing side subscriber circuit 19 by transmitting an hook-off information, then dial pulses are transmitted likewise. When there is the incoming of a call, the incoming side subscriber circuit 20 confirms the incoming by receiving a ring tone-transmission instruction from a control part 16, then informs the arrival to the circuit 19 by transmitting a ring tone from its tone transmission circuit 6 via a channel switch 17, in order to execute the pseudo call test.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a pseudo call testing device for conducting a pseudo call test on an exchange.

[Prior Art] ゛The conventional pseudo-call testing method for switching equipment is to test the subscriber circuit by equipping the subscriber circuit with the necessary functions for testing, such as an external e-loop formation function and dialing function, and connecting it to a fan.

[Problem that the invention seeks to solve]

However, this conventional method requires a switch and trial FA.
However, it has the disadvantage that it takes a lot of time to connect to the device and is not easy to connect.

[Defined means of solving problems]

In the present invention, a subscriber circuit is provided with a tone transmitting means, a tone receiving means, a loop information inserting means, and a pseudo call control section.

[For production]

Confirmation is performed by sending and receiving tones.

〔Example〕

The figure is a block diagram showing an entire embodiment of the present invention. In the same figure, 5 and 6 are tone transmitting circuits, γ and 8
Pseudo call control unit 13 for controlling the tone receiving circuit 9 and the 1° loop information insertion circuit 9 and 1o;
and 14 are line concentration switches, 15 and 16 are the line concentration switches 13 and 14, subscriber circuits 19L and 2ot.
- Control unit to control each, IT is a communication path switch, 1
8 is a central control unit.

Note that 19 is a tone transmitting circuit 5. A subscriber circuit consisting of a tone reception circuit 7, a loop information insertion circuit 9, and a pseudo call control section 11; 20 is a tone transmission circuit 6. Tone receiving circuit 8. Loop information insertion circuit 10 and pseudo call control unit 12
21 is a subscriber circuit 19. The subscriber circuit device is composed of a concentrator switch 13 and a control section 15, and 22 is a subscriber circuit 20. Concentration switch 14. This is a subscriber circuit device composed of a control section 16.

Next, the operation of this device will be explained. The subscriber circuits 19 and 20 shown in the figure are replaced with the subscriber circuits installed in the line to be tested. First, to simplify the explanation, during the friend pseudo call test, the subscriber circuit 19 is assumed to be the originating side, and the subscriber circuit 20 is assumed to be the Kim Kiyoshin side.

The calling side transmits the off-hook information from the loop information insertion circuit 9 of the subscriber circuit 19, makes a call, and after determining the timing,
A dial pulse is sent from the loop information insertion circuit 9 to perform dialing. - When the subscriber circuit 20 receives a call, the control unit 16 receives an order for sending a ring tone, confirms the reception, and sends loop information to notify the calling party of this fact. The insertion circuit 10 responds with a full wave of off-hook information, and the tone transmission circuit 6 sends a tone to the subscriber circuit 19 via the communication path switch 17. Next, in the subscriber circuit 19, this tone is received by the tone receiving circuit T as a response confirmation, and the tone is sent from the tone transmitting circuit @5 to the subscriber circuit 20 via the communication path switch 1T. And subscriber times.

In line 20, this tone is received by the tone receiving circuit 8, the tone transmission circuit 6 stops sending the tone, and the loop information inserting circuit 10 sends on-hook information to disconnect the tone. In the subscriber circuit 19, the tone reception circuit VPI7
K! When the retone is cut off, it is received and the on-hook information is sent from the loop information insertion circuit S and disconnected. By operating in this manner, a pseudo call test can be performed.

〔Effect of the invention〕

As explained in detail above, according to the pseudo call testing method according to the present invention, there is no need to prepare any equipment external to the exchange, and the subscriber circuit can be replaced with a package configured for pseudo call testing. This has the advantage that pseudo call tests can be performed with ease.
