Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a telephone exchange installed in the premises of a business office or the like, which performs switching connections between a large number of extension telephones.

Conventional technology Traditionally, private telephone exchanges installed within the premises of business offices, etc. have individual control data for each extension terminal so that each extension terminal can have individual functions according to the convenience of the user. There is something, and it usually operates according to this control data. For example, when moving an extension telephone housed in a private branch exchange when relocating a workplace, etc., it is necessary to move not only the telephone itself, but also the control data.

Conventionally, this work involved rewriting the control data of the private branch telephone exchange using a maintenance-specific command from a maintenance device such as a maintenance panel or a terminal with a CRT.

Problems to be Solved by the Invention However, the above-mentioned conventional method requires specialized knowledge regarding the maintenance of private branch exchanges, so it is necessary to request the maintenance manager to move the extension telephone. However, there was a problem in that general users could not easily move extension telephones by hand when relocating workplaces or the like. Further, even if the user has specialized knowledge, there is a risk of setting data incorrectly when rewriting the m control data.

The present invention has been made in view of the above-mentioned conventional problems.
It is possible to automatically rewrite control data when an extension telephone is moved, and easily move the housed extension telephone.
This provides a private branch telephone exchange that can be used.

In order to solve the above-mentioned conventional problems, the present invention provides an updatable management table that stores terminal-specific codes and extension ports in association with each other. When sent, it records that the extension terminal is not connected to the extension port to which this removal request signal was input, and identifies the terminal unique code of the extension terminal using the password information sent from the extension terminal. When an attachment request signal is sent from an extension terminal, it is recorded that the extension terminal is connected to the extension port to which this attachment request signal was input, and the password information sent from the extension terminal is recorded. The terminal-specific code of the extension terminal in question was identified.

Effect With the above configuration, the extension port from which the extension terminal was moved can be specified as the extension port to which the removal request signal was input, and the extension port to which the extension terminal was moved can be specified to the extension port to which the attachment request signal was sent. Since an extension telephone that can be specified as an extension port and has been moved is specified based on the password information, the contents of the management table can be automatically rewritten based on this information.

Embodiment FIG. 1 is a functional block diagram showing only the main functions related to the present invention of a private branch exchange in an embodiment of the present invention. In FIG. 1, 101 is a data file that stores control data specific to an extension terminal in association with a terminal specific code, 102 is an extension port, and 103 is an update that stores the relationship between the extension port 102 and the terminal specific code. A possible management table 104 is an operation control means that reads control data corresponding to the terminal unique code and causes each controlled device 105 to operate using the control data. Reference numeral 106 denotes a data rewrite control means that rewrites the data file 101 and the management table 103 based on a removal request signal sent from the extension terminal, an attachment request signal sent from the extension terminal, and password information. FIG. 2 is a block diagram showing the configuration of the private telephone exchange and the configuration of connected extension terminals.

In FIG. 2, 200 is a private telephone exchange (hereinafter referred to as the exchange), and 201 to 204 are extension telephones connected to each extension port of the exchange 200. 205-20
6 is an outside line connected to the private branch exchange 200. In the exchange 200, 207 to 210 are extension telephones 201
~204 extension circuit for detecting calls, etc., 211, 212
213 is a dial reception circuit that receives dials from extension telephones 201 to 204; 214 is a tone circuit that generates dial tones; and 215 is a call path switch. Extension circuits 207-210/external circuits 205-20
6. The tone circuit 214 and dial reception circuit 213 can be arbitrarily connected. Reference numeral 216 denotes a control unit that performs exchange control using a microcomputer, and the data rewriting control means is realized by a program that operates the microcomputer. Reference numeral 217 is a storage unit that stores data necessary for performing exchange control, and the data file 101 and the management tape 102 are provided within the storage unit 217. The control unit 216 performs exchange and other controls while receiving information from the extension circuits 207 to 210.

Control data unique to each extension telephone necessary for switching control etc. is stored in the storage section 217, and the control section 216 reads the control data from the storage section 217 using a terminal-specific code when necessary.

On the other hand, in the telephone 201, 218 is the extension telephone 201.
219 is an extension telephone 20
This is a dial generation circuit for sending a dial signal from 1 to the private branch exchange 200.

The operation of the private branch exchange of this embodiment configured as described above will be explained below.

First, the system start-up of the private branch exchange will be explained based on FIG. When starting up the system, switch 20
0's control unit 216 generates terminal-specific codes equal to the number of extension telephones 201 to 204 that can be accommodated in the exchange 200 (3
01) Do. Next, create a management table that shows the correspondence between the generated terminal-specific codes and extension port numbers (
302). The extension port number is a unique number provided in each of the extension interface circuits 211 to 214, and is a physical address for controlling the extension telephone. Next, the mode shifts to control data input mode, and in this state, the user manually inputs data necessary for actual exchange control according to the extension telephone's operation schedule. The control unit constructs a control data file based on the input data (
303). That is, the input data is organized for each terminal-specific code and stored in the storage unit 217 of the exchange 200 so that it can be retrieved by specifying the terminal-specific code. Table 1 shows the data files constructed in the storage unit 217 of the exchange 200 as described above.

In the following margins, Table 1, Table 2, and Table 1, various types of control data are set for each terminal unique code. The number j of terminal-specific codes corresponds to the maximum number of extension telephones that can be accommodated in exchange 200. The control data configured in accordance with the terminal-specific code includes the extension number, the type of extension telephone (exchange dedicated telephone, PB telephone, DP telephone), settings for use or non-use of each function, etc. . The above-mentioned functions include call forwarding, call rejection, oscillation control, answering call reception, and the like.

Table 2 shows a management table, in which the extension port number indicating the location where the extension telephone is physically connected and the terminal unique code of the telephone are recorded in pairs. By specifying a terminal-specific code, the corresponding extension port number can be read immediately. Further, if the extension telephones 201 to 204 are connected to the extension port, "1" is stored, and if not, "O" is stored, thereby indicating the current connection status of the extension telephones 201 to 204.

FIG. 4 shows the main parts of the telephone exchange in more detail. For example, if the extension telephone 401 connected to a certain extension port A is a PB telephone, control data indicating this fact will be set. In this case, the extension telephone 401 is off-hook and the extension circuit 4 of extension port A is connected.
02, the control unit 216 controls the extension telephone 40.
The control data corresponding to No. 1 is read and processing is performed according to the data indicating that it is a PB telephone. That is, in this case, the crosspoint switch circuit 403 is controlled to connect the DTMF receiver 404 to the extension telephone 401 via the extension circuit 4'02. And extension telephone 401
The multi-frequency selection signal (dial signal and various control signals) sent from the DTMF receiver 404 can be received by the DTMF receiver 404. On the other hand, if extension telephone 401 is
If it is a P-type telephone, control data indicating this is set, so when off-hook is detected in the extension circuit 402 provided in extension port A, the control unit 216 operates according to the data indicating that it is a DP-type telephone. Process. That is, in this case, the DTMF receiver 404 is not connected, and the current monitoring section 405 in the extension circuit 402 detects the dial pulse signal and reads the information.

Next, a case where extension telephone 201 is removed from exchange 200 for movement will be described with reference to FIGS. 5, 6, and 2. Control unit 216 of exchange 200
constantly monitors the off-hook extension telephones 201-204. When the extension telephone 201 is taken off-hook by the user's hand, a DC loop current flows through the extension line, and the extension circuit 207 detects this and notifies the control unit 216 that a call has been made from the extension telephone 201. . Control unit 216
controls the call path switch 215 to connect the tone circuit 214 and dial reception circuit 213 to the extension circuit 207;
The tone circuit 214 is operated to send a dial tone to the extension telephone 201 (501). On the extension telephone side, the user who hears the dial tone inputs information requesting removal using an input means such as a numeric keypad. All signals from the dial generation circuit 219, such as dial number information, removal requests, installation requests, etc., are received by the dial reception circuit 213 of the exchange 200 (50
2). The control unit 216 analyzes the received signal 503)
, if it is a dialed number for an internal call or an external call and a request for normal exchange processing, normal exchange processing is performed in accordance with the request (504). If the dial analysis result indicates that there is a request to disconnect the extension, the call path switch 215 is controlled again to connect the tone circuit 214 and the dial receiving circuit 213 to the extension circuit 207, and a dial tone is sent to the extension telephone 201, and the user The user is prompted to send the extension number and ID number of the extension telephone 201 itself. and,
The dial receiving circuit 213 receives the extension number and ID number sent from the extension telephone 201 (601). When the reception of the extension number and ID number is completed, the extension number of the destination when the dial tone was first sent is compared with the extension number received thereafter (602). If they do not match, it is determined that the user has mistakenly entered an extension number different from the extension number currently in use, and a busy tone is sent from the tone circuit 214 to the extension telephone 201 to perform recovery processing such as disconnecting the line ( 605).

On the other hand, if there is a match, the connection status of the corresponding extension port is rewritten to O in the management table of the storage unit 217, and it is set as non-connected (603). Further, the received ID number is stored in the storage unit 217, and a confirmation tone is sent from the tone circuit 214 to the extension telephone 201 (604
). The ID number is a password set by the user, and when an extension phone is removed, the contents of the management table are rewritten and this password is registered, and the next time the removed extension phone is transferred to another extension. Used to check if the same extension phone is definitely connected when trying to connect to a port. In other words, when an extension telephone is removed, the link between the extension telephone itself and the terminal-specific code inside the exchange is temporarily lost, and if many extension telephones are moved at once, A large number of extension telephones are removed at the same time, and if there is nothing to associate the extension telephone itself with the terminal-specific code extension number, the mistake may not be noticed even if a different extension telephone is attached. For these reasons, in this embodiment, the extension number and ID number are required to be registered when an extension telephone is removed, and when the extension telephone is connected to another extension port, the extension number entered by the user is and ID numbers are configured to check whether they match.

Next, the removed extension telephone 201 is connected to the exchange 20 again.
FIG. 5 for the case of connecting to another extension port of 0,
This will be explained with reference to FIGS. 7 and 2. for example,
It is assumed that the extension telephone 201 removed from the extension circuit 207 is connected to another extension circuit 208. First, the user manually connects the extension telephone 201 to the extension circuit 208. However, simply by connecting to the extension circuit, exchange 200 does not show any response. Next, extension telephone 20
1 goes off-hook by the user's hand, a DC loop current flows through the extension line, and the extension circuit 207 detects this and notifies the control unit 216 that a call has been made from the extension telephone 201. The control unit 216 controls the call path switch 215 in the same way as during normal operation, connects the tone circuit 214 and dial receiving circuit 213 to the extension circuit 207, operates the tone circuit 214, and sends a dial tone to the extension telephone 201. Send (501). On the extension telephone side, the user who hears the dial tone inputs information indicating a request for installation using an input means such as a numeric keypad. In response to the input of this information, a signal is sent from the dial generation circuit 219 to the exchange 200, and is received by the dial reception circuit 213 of the exchange 200. The i control unit 216 first analyzes the received signal according to the normal procedure (50
3). If the dial analysis result indicates that there is a request to attach an extension, the call path switch 215 is controlled again to connect the tone circuit 214 and the dial receiving circuit 213 to the extension circuit 2.
07, sends a dial tone to the extension telephone 201, and prompts the user to send the extension number and ID number of the extension telephone 201 itself. Dial receiving circuit 21
3 is the extension number and ID sent from the extension telephone 201
701), and when the reception is completed, the control unit 216 is notified of the received extension number and ID number. The control unit 216 first compares the extension number of the other party when the dial tone was sent and the extension number received thereafter (702). If they do not match, a busy tone is sent from the tone circuit 214 to the extension telephone 201 and recovery processing such as disconnection of the line is performed (706). In addition, the control unit 216 compares the ID number previously sent and registered from the extension telephone according to the dial tone with the ID number received as described above (703), and if they do not match, the above case is applied. Perform recovery processing in the same way.

On the other hand, if it is found that the extension number and ID number received in step 702 and step 703 match those already registered, the connection status of the corresponding extension port is set to 1 in the management table of the storage unit 217. and rewrites the terminal-specific code field in the management table to a new terminal-specific code specified by the sent extension number (704). Then, the tone circuit 214 is controlled to send a confirmation tone to the extension telephone 201 side to notify that the connection process has been completed (705).
. The control data based on the terminal-specific code remains as previously set, and the control section a 216 of the private branch exchange 200 reads the control data set for each terminal-specific code using the terminal-specific code as before. However, exchange control is performed accordingly. Therefore, the extension telephone 201 can be used in the same way as before being removed without setting new control data.

Effects of the Invention As described above, the present invention, when a removal request signal is sent from an extension terminal, records that the extension terminal is not connected to the extension port to which this removal request signal is input, and also removes the extension terminal from the extension terminal. The terminal unique code of the extension terminal is identified by the password information sent from the extension terminal, and when an attachment request signal is sent from the extension terminal, the extension terminal is connected to the extension port to which this attachment request signal was input. By recording the connection and identifying the terminal-specific code of the extension terminal from the password information sent from the extension terminal, the extension terminal can be removed from the extension port to which it was previously connected. When attempting to connect to another extension port, the exchange requires complicated data movement by using the extension port number of the extension port into which the removal request signal and attachment request signal were input, and the terminal-specific code specified by the password information. The management table showing the correspondence between the extension port to which the extension terminal is connected and the terminal-specific code can be automatically rewritten without any work. Since the control data is not unique to the extension port, but is organized so that it can be identified by the terminal-specific code, there is no need to re-set control data such as extension numbers when moving the extension terminal within the workplace. Yes, the previously input control data can be used continuously, which saves maintenance costs for the user and makes it very easy to move the extension terminal.
