CONSTITUTION:A speech path equipment 6 of a new model electronic exchange provided with new functions is provided with an interface converter 5 for interface where subscriber line devices (LC) 2, an outgoing trunk 3, and an incoming trunk 4 of the old model electronic exchange are stored. A central control equipment 7 of the new model electronic exchange is provided with a means which controls LCs 2, the outgoing trunk 3, and the incoming trunk 4 through the speech path equipment 6 and the interface converter 5. A test equipment 8 of the new model electronic exchange is provided with a means which tests the central control equipment 7, the speech path equipment 6, LCs 2, the outgoing trunk 3, and the incoming trunk 4. The speech path equipment, the central control equipment, and the test equipment of the old model electronic exchange are replaced with the speech pach equipment 6, the central control equipment 7, and the test equipment 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for introducing a new function in a storage program control type electronic exchange.

[0002]

2. Description of the Related Art Conventionally, in a new function introduction system for adding a new function to an old electronic exchange, for example, a Centrex function,
ISDN and NO. It is not possible to add new functions such as the 7-signal system, and new functions are provided by replacing all old electronic exchanges with new exchanges having new functions.

[0003]

As described above, in the method of introducing the new function into the conventional old electronic exchange, there is a drawback that all the new exchanges have to be replaced. Therefore, the device is wasted and a new one is newly added. Huge costs were also required.

The object of the present invention is to use the subscriber line equipment and trunk equipment which occupy most of the old electronic exchange as they are and to inexpensively use the same Centrex function as that of the new exchange.
SDN and NO. It is to introduce new functions such as the 7-signal system into the old electronic exchange.

[0005]

A new function introduction system in an electronic exchange according to the present invention is a communication system of a new exchange having a new function in a new function introduction system in an electronic exchange for introducing a new function to an old exchange. The device is provided with an interface conversion device for accommodating the subscriber's line device and the trunk device of the old-type exchange and enabling interfacing with the old-type exchange, and the central control system device of the new exchange is provided with the speech path system device and the A means for controlling the subscriber line device and the trunk device of the old exchange is provided through an interface conversion device, and the test system device of the new exchange includes the central control system device, the speech path system device, and the subscriber of the old exchange. A means for testing the line device and the trunk device is provided, and the communication path system device, the central control system device and the test system device of the old type exchange are respectively provided. Speech path apparatus of the new exchange, and
The configuration is such that the central control system device and the test system device can be replaced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram for explaining an embodiment of the present invention. In order to introduce a new function into an old electronic exchange of a storage program control type, a communication path system device and a central control of this old electronic exchange. The system device and the test system device are replaced with the communication path system device 6, the central control system device 7 and the test system device 8 of the new electronic exchange of the stored program control type.

The call path system device 6 of the new electronic exchange is a subscriber line device (hereinafter referred to as LC) 12, an outgoing trunk 13, an incoming trunk 14 and an ISDN subscriber line device (hereinafter referred to as DLC) 10 of the new electronic exchange. In order to accommodate the subscriber line device (hereinafter referred to as LC) 2 of the old type electronic exchange, which has a different interface, the outgoing trunk 3 of the old type electronic exchange, and the incoming trunk 4 of the old type electronic exchange. The interface conversion device 5 is installed to convert the interface.

Under control of the central control unit 7 of the new electronic exchange, the LC 2 of the old electronic exchange in which the subscriber 1 of the old electronic exchange is accommodated, the outgoing trunk 3 of the old electronic exchange 3, and the incoming trunk 4 of the old electronic exchange. On the other hand, a call connection is established through the communication path system device 6 and the interface conversion device 5.

Further, since the central control system device 7 has various new functions, for example, the center function, NO. Various new functions such as 7-signal system can be introduced. Further, since the new electronic exchange has the DLC 10, it is possible to accommodate the ISDN subscriber 9, and when adding subscribers and trunks, the new electronic exchange LC1
2, the outgoing trunk 13 and the incoming trunk 14 may be installed.

The test system equipment 8 includes not only the communication path system equipment 6, the central control system equipment 7, the DLCs 10, LC12, the outgoing trunk 13 and the incoming trunk 14 of the new electronic exchange, but also the old electronic exchange LC2, the outgoing trunk 3 and the incoming trunk 3. The trunk 4 also has a function for testing.

[0012]

As described above, according to the present invention, the communication path system device of the new exchange, the subscriber line device and the trunk of the old exchange, which is equipped with the interface conversion device capable of accommodating the subscriber line device and the trunk device of the old exchange, are provided. By replacing only the central control unit of the new exchange that can control the equipment and the test system equipment of the new exchange that made it possible to test these with the old exchange, waste is eliminated and the old exchange is the same as the latest exchange. Centrex function,
ISDN subscribers and NO. This has the effect of introducing new functions such as the 7-signal system.
