DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange for performing mutual data conversion between incoming and outgoing lines in office data information for managing incoming and outgoing lines.

[0002]

2. Description of the Related Art Conventionally, a base station connected to a switching system has
Switching system for managing multiple slave stations and subscriber terminals
As the system, there is one as shown in FIG. Smell
Therefore, the switching center 100 outputs a plurality of outgoing lines O (O₀~ O_n) Via
And is connected to the base station 200.
The antenna 201, the radio path, the antenna 301 (301₀
~ 301_n) Through a plurality of slave stations 300 (300₀~ 3
00_l)It is connected to the. Further, the slave station 300 (30
0₀~ 300_l) Has incoming line I (I₀₁~ I_0m... I _l0~ I
_lm), A plurality of subscriber terminals 310 (310) respectively.
₀₀~ 310_0m... 310_l0~ 310_lm)It is connected to the
The state is shown.

[0003] In such a state, an arbitrary subscriber terminal 310 accommodated in the slave station 300 connects to a specific outgoing line O via the base station 200 at the time of originating a call. When there is an incoming call from the exchange 100, the incoming call is sent to the subscriber terminal 310 connected to the outgoing line O. And the base station 200
And the outgoing line O connecting the exchanges.

That is, the outgoing line O of the base station 200 and the slave station 3
00, the number of the subscriber terminals 310 accommodated in the slave station 300 does not match the number of incoming lines I, or the subscriber terminal 310 accommodated in the slave station 300 moves and is accommodated in another slave station 300. The terminal 310 becomes the switching center 100 and the base station 20
Base station 2 when the outgoing line O connecting to
At 00, information in which the incoming line I connecting the slave station 300 and the subscriber terminal 310 is associated with the outgoing line O connecting the base station 200 and the exchange, that is, if the office data is prepared, the connection of the outgoing line O is bothersome. It is possible to move any subscriber terminal 310 to any location without changing the connection of the incoming line I.

[0005] For the above reasons, a management method using station data is generally adopted. As a method for creating the station data, a device using the station data has an external interface. Although there is a method of creating the station data, generally, a method has been adopted in which the operation program and the operation data are separated and the station data is created by another device dedicated to station data creation.

[0006] This is because an error in the station data causes a failure such as a system down, and it is difficult to create a program by incorporating an error check function of the station data into the operating device in addition to the original conversion processing function. The reason is that it becomes. Therefore, by creating the station data by the dedicated station data creation device, an easy and reliable check function can be provided even for station data having a complicated configuration.

And a conversion table for performing data conversion from an outgoing line to an incoming line, respectively, thereby enabling reversible conversion, and shows an exchange system in which station data created thereby is applied to an operation device. In the figure, the switching system 400 includes a signal line 43
3. Switching device 411 connected to station management device 412 via
And a switching device 421 connected to the station management device 422 via the signal line 434.

[0008] The switching device 411 is connected to the operator terminal 417 via a signal line 435.
The switching device 421 is connected to the operator terminal 42 via a signal line 436.
7 is connected. Each of the switching devices 411 and 421 includes an office data registration signal transmission circuit (hereinafter, CSG) 413 and 42.
3 and a handler intervention signal determination circuit (hereinafter referred to as SID) 41
4 and 424, and communication control circuits 415 and 425, respectively.
Are station data registration tables (hereinafter, TBL) 416, 4
26 is built in.

A procedure for remote control of station data registration from switching apparatus 411 to switching apparatus 421 in the above configuration will be described. First, when the operator terminal 417 connected to the switching device 411 is to send a handler intervention signal by designating the switching device 421 by a meeting notification, the communication control circuit 415 transmits the switching device 421 via the trunk line 431. Output the handler intervention signal to the On the other hand, in the switching device 421 to which the operator intervention signal has been input via the trunk line 431, the input operator intervention signal is transmitted to the SID 424 via the communication control circuit 425 and the signal line 440.
To receive.

[0010] The SID 424 checks the operation state of the own station, and determines whether or not it is possible to act on behalf of the operator. In this determination processing, if it is determined that the agent can be substituted,
The ID 424 returns an operator intervention possible signal to the switching device 411 via the signal line 440, the communication control circuit 425, and the relay line 432. In addition, in the process of judging whether or not the agency of the handler is possible, if it is determined that the agency of the handler is not possible, the SI
D 424 returns the operator intervention impossible signal to the switching device 411 via the signal line 440, the communication control circuit 425, and the relay line 432.

When the switching device 421 receives an input of a handler intervention possible signal via the trunk line 432, the switching device 421 notifies the operator of the input. In response to this, the operator notifies the exchange device 421 of the additional code for identifying the registration of the office data and the exchange device 421 of the dial number for which the office data is to be registered. In the exchange device 421,
When receiving the notification of the additional code and the dial number, the communication control circuit 425 transmits the information to the TBL 426.
Collation with the station data registration permission number stored in the. As a result of the comparison, if the two match, the CSG 423 determines
A station data registration signal is transmitted to the station management device 422 via the signal line 434, and new station data information is registered.

On the other hand, as a result of the collation, if they do not match, the CSG 423 transmits a station data registration disable signal from the communication control circuit 425 via the trunk line 432. In the switching device 411, when the communication control circuit 415 receives the station data registration disable signal, the signal line 439 and the SI
Through D414 and the operator line 435, a display (not shown) provided on the operator terminal 417 indicates that station data registration has been disabled. Thereby, at the time of the office data registration, the office data registration can be performed for the switching device 421 installed at the remote place by the instruction control by the operator terminal 417, so that the labor for going to the remote place and registering the data is required. Can be eliminated.

[0013]

However, in such a conventional switching system, when the management target station, which is the switching device for registering station data, is constructed, various states occur due to an operation test or the like. When viewed from the management device side, such a state change is caused by a failure, is caused artificially for a test, or
It is not possible to judge whether it is due to a mismatch in station data registration or the like, and this includes an element that the more stations that need to be managed, the more complicated it becomes.

In such a situation, when the station data is created off-line by using the station data creation device,
The problem of lack of responsiveness is greatly highlighted. That is, there is a possibility that station data that has been created with great effort will be station data that does not match the current system when it is registered in the operation system.

An object of the present invention is to provide a data conversion circuit and an exchange device for easily and quickly creating station data to solve the above problems.
