Abstract

PURPOSE:To improve the measuring accuracy in measurement of traffic capability of an exchange by executing hook-up of a pseudo telephone set circuit and the calculation of answer time automatically. CONSTITUTION:A start control circuit 4 controls a telephone set hook-up start circuit 3 to give a signal simultaneously to each pseudo telephone set circuit 3 and records the time. Each circuit 2 hooks up simultaneously and gives a call signal to a line circuit 11 of an exchange 10. Each circuit 11 is started one after another and connected to an idle register in dial registers 12 by a channel switch 13. A dial tone T1 is given from the circuit 11 and a busy tone T2 is returned to the circuit 2 from the circuit 11 not connected yet. A detection circuit 5 detects the tones T1, T2 and the time for the case is recorded by a time measuring circuit 6. A time comparison circuit 7 obtains the answer time at each circuit 2 from the content of the circuits 4, 6. A microcomputer 8 applies statistic processing based on the answer time data and the result is displayed on a display device 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for measuring the performance of a switch.

[Conventional technology]

Conventionally, the traffic capacity of an exchange has been measured by a person manually hooking up a plurality of pseudo telephones and operating a stopwatch.

[Problem that the invention seeks to solve]

However, with such a measurement method, it is difficult to perform measurements with sufficiently high precision.

This invention has been made to solve the above-mentioned problems.

[Means for solving problems]

The exchange traffic capability measuring device according to the present invention includes a plurality of pseudo telephones, a hookup means for automatically hooking up the pseudo telephones, and a hookup means for automatically hooking up the pseudo telephones, and a hookup means for automatically hooking up the pseudo telephones; The present invention is characterized in that it comprises a detection means for detecting a signal, and a time measurement means for measuring the time from the hook-up of the pseudo telephone to the detection of the signal.

[Effect]

The pseudo telephone is automatically hooked up by the hookup means without any manual intervention, and in response to this, a signal sent back from the exchange to the pseudo telephone is detected by the detection means.

The time from hook-up to detection is automatically measured by a time measuring means without any manual intervention. Hook up like this.

Since time measurement is performed automatically without manual intervention, highly accurate traffic performance measurements can be made.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The figure shows an embodiment of an exchange traffic capacity measuring device according to the present invention. This exchange traffic capability measuring device 1 includes a plurality of pseudo telephone circuits 2, a telephone hook-up starting circuit 6 that provides a hook-up command signal s1 to each circuit 2, and a telephone hook-up starting circuit 6 that controls the circuit 3 and that controls each circuit 3. An activation control circuit 4 is provided that records the time at which the signal s1 is applied to the circuit 2. The outgoing signals of the pseudo telephone circuit 2 hooked up by the signal S1 are respectively input to the line circuits 11 of the exchange 10 which is the object of measurement.

The device 1 also receives a so-called dial tone that is sent back from the line circuit 11 to the pseudo telephone circuit 2 in response to the hook-up of the pseudo telephone circuit 2. TI or so-called busy tone (a signal that indicates that there are no more free registers in the register 12 and it is impossible to accept dialing because more than a predetermined number of telephones have hooked up at the same time) T2 is sent to each circuit 2. A dial tone/busy tone detection circuit 5 for detecting, a detection time measuring circuit 6 for recording the time at which the circuit 5 detected tone T1 or T2 for each circuit 2, and the time recorded in the circuit 6 and the activation control. A time comparison circuit 7 is provided for determining the difference (response time) between the times recorded in the circuits 4 for each circuit 2. Data indicating the response time of each circuit 2 determined by the circuit 7 is given to a microcomputer 8 provided in the device 1. The microcomputer 8 is
Based on this data, predetermined statistical processing (calculation of average response time and minimum and maximum response times) is performed.

This is used to create response time distribution tables, etc.).

The processing results are given to a display 9 provided in the device 1.

An example of the operation of measuring the traffic capacity of the exchange 10 by this device 1 will be shown below.

Under the control of the activation control circuit 4, the telephone footer up activation circuit 3 gives the signal S1 to each pseudo telephone circuit 2 all at once (at this time, the circuit 4 also records the time at which the circuit 3 gave the signal S1 to each circuit 2). carried out). Then, each circuit 2 hooks up at the same time and the outgoing signal is given to the line circuit 11 of the exchange 10. As a result, each circuit 11 is activated one after another, and each circuit 11 is connected to an empty register in the dial register 12 by the communication path switch 13 (this connection operation is well known as the operation of an exchange). (details omitted).

A dial tone T1 is sent back to the circuit 2 from the circuit 11 connected to the register 12, and a busy tone T2 is sent back to the circuit 2 from the circuit 11 that is not connected because there is no vacant register. The tones TI, T2 sent back to each circuit 2 are detected by the detection circuit 5, which detects each tone T1. T
The time when 2 is detected is recorded in the time measurement circuit 6. The time comparison circuit 7 calculates the response time for each circuit 2 based on the recorded contents of the circuit 6 and the recorded contents of the circuit 4. The microcomputer 8 performs statistical processing based on the data indicating this response time, and the display 9 displays the processing results.

In this way, this exchange traffic capacity measuring device
4. Activate hookup of pseudo telephone circuit 2; control circuit 4. Automatically performed by the telephone footer up activation circuit 3,
The response time is automatically calculated by the activation control circuit 41, the time measurement circuit 61, and the time comparison circuit 7, thereby measuring the traffic capacity of the exchange.

〔Effect of the invention〕

As described above, according to the exchange traffic capacity measuring device according to the present invention, the traffic capacity of the exchange can be automatically measured without manual intervention, and therefore the accuracy of the measurement can be improved.
