JPH05191495A - Automatic switching system for director/responder function - Google Patents

Abstract

PURPOSE:To prevent the device from becoming larger scale due to increase in the number of more director/responders than necessary by providing a controller switching the function of the director/responder by controlling software as needed. CONSTITUTION:When a line measurement command is inputted from a maintenance operation terminal 6, it is sent through a central control device 5 to a controller 4. The controller 4 controls a measurement device 3 to function as a director, and sends measurement signals through a time division network 72 to a trunk 1. On the contrary, when the trunk 1 receives measurement signals from an international line, it is sent through the network 2 to the device 5 and the controller 4 controls the measurement device 3 to function as a responder by receiving information from the device 5. Thus, the ability processing test/measurement commands per measurement is improved for the opposite station, providing the flexibility on the test/measurement schedule.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an international exchange, and more particularly to an automatic transmission line measuring device for an international line between exchanges.

[0002]

2. Description of the Related Art In the conventional system, in an international exchange,
Despite the fact that there is a device that has both the functions of a director and a responder, in order to equip it as a device, it was necessary to set it to either one of the functions and equip it.

[0003]

As described above, in the conventional method, the director and the responder can be used only as their respective functions, so that the director and the responder must be provided as separate devices. .. Therefore, if a large number of measurement commands from your own station or from the opposite station overlap, you cannot use the measuring instruments that have been set with another function, and you must increase the measuring instruments that have the necessary functions. There was a problem that it had to be.

An object of the present invention is to provide an automatic switching system of the director / responder function which allows flexibility in the test / measurement schedule.

[0005]

In order to achieve the above object, an automatic switching system of a director / responder function according to the present invention has a function as a director in an automatic transmission line measuring apparatus having a director and a responder of an international exchange. It has a controller for switching the function as a responder by software control as necessary.

[0006]

Function: The measuring device is set in advance as the director or the responder, and its function is switched as required by the control of the software.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a relay system diagram showing an embodiment of the present invention.

In FIG. 1, 1 is a trunk, 2 is a time division network, 3 is a measuring instrument, 4 is a controller, 5 is a central control unit, and 6 is a maintenance operation terminal. Here, the controller 4 has a function of switching between a function as a director and a function as a responder by controlling software as needed.

In the embodiment, when a line measurement command is input from the maintenance operation terminal 6, it is sent to the controller 4 via the central control unit 5.

The controller 4 controls the measuring device 3 to function as a director, and the director transmits the measurement signal to the trunk 1 via the time division network 2.

On the contrary, when the trunk 1 receives the measurement signal from the international line, it is sent to the central control unit 5 via the time division network 2, and the controller 4 receives the information from the central control unit 5 and sends the measuring device 3 to the responder. Control to function as.

[0012]

As described above, according to the present invention, the director and the responder, which are conventionally separately prepared, are set in advance as one of the functions of the director and the responder.
By switching the function as needed, even if a large number of measurement commands are overlapped, the test / measurement schedule can be increased to the opposite station without increasing the number of measurement devices and the ability to digest test / measurement commands per measurement device. Can be flexible.
