When a call arrives to a multi-line to which a certain number has been assigned, the central processing unit 100 sends a message to all multi-function telephone control circuits 140 to 142 via the common control information transfer path 130 according to the format shown in FIG. Send common control information. Each of the multifunction telephone control circuits 140 to 142 has a line allocation memory 301 configured to correspond to the multifunction telephone.
The line number set in the line number memory 302 is compared with the line number information 401 sent by the control information, and lamp control information 403 is set in the line lamp memory 306 corresponding to the line number memory 302 that matches. do. Ringer control information 402 is set in line ringer memory 305 by referring to the contents of ringer allocation memory 303 and multifunction telephone status memory 300 .

Therefore, the lamp control information 403 is stored in the line status memory 304 of all multi-function telephones to which the same number as the received multi-line call is assigned.
is set, and the ringer control information 402 is set only in the ringer memory corresponding to the telephone for which ringer control is required.

Apart from the above-described processing, each multifunction telephone control circuit 140-142 periodically checks the line lamp memory 306 and stores the line lamp memory 306.
The line lamp 201 of the corresponding multifunction telephone is controlled based on the information set in . Therefore, the line lamp 201 of all multifunction telephones to which the line number of the incoming multiline is assigned
flashes. In addition, the multi-function telephone status memory 30
0 stores the state of each multifunction telephone, and the ringer 202 of the multifunction telephone rings as required by the contents of the multifunction telephone state memory 300 and the ringer assignment memory 303.

Now, for example, when the multifunction telephones 160 and 162 ring and the corresponding line lamps of the multifunction telephones 160 to 162 flash, it is possible to answer from any of the multifunction telephones 160 to 162. .

Now, for example, when the multifunction telephone 162 answers, the user presses the line button 200 corresponding to the blinking lamp 201 and takes the handset 203 off-hook. As a result, the multifunction telephone control circuit 141 sets the identification information of the multifunction telephone 162 that responded in the multifunction telephone identification information 501 and sets the code indicating the response in the detection event information 502 according to the format shown in FIG. Then, the line number corresponding to the pressed line button 200 is set in the line number information 503 and the control information return path 1 is set.
Control information is sent to the central processing unit 100 via 21.

Based on the returned control information, the central processing unit 100 controls the connection of an exchange (not shown) so as to connect the responding multifunction telephone 162 to the calling terminal, and at the same time, the common control information transfer path 13
0, the multiline number that received the response, ringer off control information, and lamp continuous lighting control information are sent out according to the format shown in FIG. As a result, the incoming call display on each of the multifunction telephones 160 to 162 for the answered multiline is stopped, and the line lamp 201 is lit continuously. In other words, a busy display is displayed.

Further, the central processing unit 100 sends the individual control information in the format shown in FIG. The function telephone control circuit 141 controls the responding multifunction telephone 162 based on the information.

Here, the operation will be explained with reference to FIG. 7, which shows an example of the storage contents specifically set in the line assignment memory 301 and the line state memory 304.

The line number memory 302 of the line assignment memory 301 corresponding to the multifunction telephone 162 of a certain multifunction telephone control circuit 141 contains line numbers 5000 to 5005 of lines to which the multifunction telephone 162 can be connected.
The ringer allocation memory 303 stores information on whether or not to ring when a call arrives on which line, using "1" and "0". It is set. Additionally, the multi-function telephone status memory 300 includes:
Information indicating whether this multifunction telephone 162 is "empty" or "busy" is set. "Empty" means an on-hook state, and "busy" means an off-hook state. This can be set by "1" and "0". In addition, the line lamp memory 306 stores settings for three states: "lit" to indicate that the line is in use, "off" to indicate that it is idle, and "flashing" to indicate that there is an incoming call. .

For example, when a call is received on line 5001, the common control information from the central processing unit 100 sets lamp blinking control information in the line lamp memory 306 corresponding to line 5001 in the line number memory 302. The line lamp 5001 of the line lamp 201 of the multifunction telephone 162 blinks. Also, since the memory content of the ringer allocation memory 303 corresponding to line No. 5001 is "1",
"1" is set in the line ringer memory 305 and the ringer 202 rings. At this time, the line
When there is an incoming call to number 5004, the lamp of line number 5004 blinks, but since the ringer allocation memory 303 is set to "0", the line ringer memory 305
remains "0". If the multi-function telephone status memory 300 is "empty" when a call arrives on line 5001, the line ringer memory 305 is "1".
Then, the linga sounded. If the multifunction telephone status memory is "busy", the ringer will not ring even if the line ringer memory 305 is set to "1".

〔Effect of the invention〕

As described above, in the present invention, multifunction telephones are classified into a plurality of groups, and specific information is transferred between a plurality of multifunction telephone control circuits that control the multifunction telephones of each group and a central processing unit. line number information, ringer control information, and lamp control information of the incoming multiline are sent from the central processing unit to all the multifunction telephone control circuits by common information transfer. Since the multi-function telephone control circuit is configured to perform incoming call display, ringer control, etc. for each multi-function telephone to which the same line number as the incoming multi-line is assigned, the multi-line control circuit of the central processing unit It is possible to reduce the required processing time and eliminate the need for a storage device for multi-line control of the central processing unit. Therefore, there is an effect that multi-line allocation can be set more freely than in the conventional method.
