4 and a voice response unit (hereinafter referred to as VRU) 5 are connected, and the number of slave units 4 installed in the main unit 1 is, for example, (m-4).
In this case, the main device 1 and each slave device 4 are connected by one pair of lines 31 (31 to 3 m-4) each consisting of a communication line and a signal line, and one pair each is connected between the main device 1 and VRUS. It is connected by 3m-3m of communication lines and signal lines.

The outside lines 21 to 2n each have an outside line interface 111.

13m, and exchange connections between the outside M2t to 2n and each of the slave units 4 to VRU5 and between each of the slave units 4 to VRU5 are made by cross points such as analog switches or relay contacts in the communication path switch 12. is to be carried out.

The outside line interfaces 111 to 11n have functions such as incoming call detection, DC loop closure for outside lines, hold, and dialing using pulse signals or composite voice frequency (DTMF) signals.
2n and each slave unit 4 to VRU5 and each slave unit 4 to VR
While having an exchange connection function between U5s, the telephone interfaces 131 to 13rn supply power for communication via communication lines to each slave unit 4 to VRU5, transmit and receive data signals via signal lines, and supply power for control. It is supposed to provide supplies, etc.

The main device 1 also includes a processor such as a microprocessor (CPU) 14 and a fixed memory (ROM).
) 15 and a control unit using a variable memory (RAM) 16, the processor unit 14 executes the program in the ROM 15, and stores predetermined data in the RAM 16.

Control decisions are made according to operation data from each handset 4 to VRU5 via telephone interfaces 131 to 13m, and external line interfaces 111 to 11n1
Communication path switch 12゜t Packing machine interface 131
-13m, and also controls each slave unit 4-VR [J5] by transmitting control data via telephone interfaces 131-13m.

On the other hand, in each handset 4, a communication circuit 42 is connected to the communication line 41A, and a transmission circuit 43 is connected to the signal line 41B, which is similar to the control section of the main device 1, but more Small processor unit 44 and ROM
45A and RAM 45B is connected to the control unit, and in response to control signals sent from the main device 1 via the transmission circuit 43, it emits an incoming ring tone and turns on/off/blinks each indicator light in the keyboard 46. etc., and also transmits operation data indicating these conditions to the main device 1 via the transmission circuit 43 in response to the operation of each button on the keyboard 46 and the operation of the hook switch I (8). ing.

Note that the transmission circuit 43 has a power supply separation function, and the signal line 4
One source is supplied from the main device 1 side via 1B, is stabilized, and is supplied as a local power supply V to each part that requires it.

Therefore, when off-hook is performed on any handset 4, its operation data is received by the processor unit 14, and the key operations on the keyboard 46 are also performed in the same way. The processor unit 14 controls the call path switch 12 and performs exchange connection, and if the call is an outside line call, the dial call is made under the control of the selected outside line interface 11, and if the call is an extension call, the remote phone 4 of the other party is dialed. By controlling the display path 47, an extension ringing tone is emitted, and when the other party responds, the call state is established.

Further, incoming calls from the outside lines 21 to 2n are detected by the outside line interfaces IL+ to 11n, and in response, the processor unit 14 controls each slave unit 4 to RU5.
To emit the incoming call tone, select one of the handsets 4-V.
When the RU 5 responds with an off-hook operation, the processor unit 14 controls the call path switch 12 accordingly to complete the call path.

On the other hand, the VRU 5 is connected to the four button telephone connection boats CNrn-3 to CNm in the main unit 1 via lines 3m-3 to 3m of telephone lines and signal lines, as shown in FIG. , the signal line 5 of the line 3m-3 to 3m

In response to incoming call data arriving via 524, response data is sent back, and during response, message recording and playback operations are performed based on command data arriving via call line 51A and signal line 51B. There is.

In this case, the VRU 5 converts the DTMF data arriving from the outside line via the communication line 51A into DTM data as command data.
It is received by the F receiver 54, and is also transmitted from the extension telephone to the signal line 5.
Key data arriving via 1B is received by transmission circuits 521 to 524 as command data. In addition, KSUl
receives the key data from handset 4, creates the same data, and sends it end-to-end (e
(nd-to-end) signals.

In this way, by connecting '/R[35 in parallel to the connection ports CNrn-3 to CNrn for multiple button telephones in KSUl, data transmission and data codes similar to those of ordinary button telephones are configured from the perspective of KSUl. It is possible. However, for functions with vRU5%, the boat KV
This will be done to indicate that RU5 is connected.

That is, multiple connection bauds of KSUl)CNm-3~C
When VRU5 is connected in parallel to Nm via line 3m-3 to 3m, KSUl sends an end-to-end signal during an internal call with VRU5 and transfers an internal or external call when making an internal call to VRU5. At the same time, a new transmission data code is added as a precaution to transmit the calling handset number, called handset number, and outside line number to the VRU 5. On the other hand, V
The RU5 automatically analyzes the code and the data sent to a regular key telephone, and in response to an incoming call from the KSUI, plays and sends which message based on the calling and called number data. The transmission circuits 521 to 521 transmit end-to-end data from the calling telephone while executing predetermined operations.
524, and in the case of an outside line, the DTMF receiver 54 receives the dial code. After the message recording/playback operation is completed, the data is analyzed to determine where to transfer it or whether to end the call, and in the case of transfer, a data code equivalent to the transfer operation code issued from the button telephone is sent to the KS. If the call ends, an on-hook code is sent to KSUl and the call ends.

Therefore, as described above, most of the processing is performed in the VRU 5, and in the call processing of KSU1, the newly added processing is only the above-mentioned special transmission data to the VRU 5.

Next, the operation of the configuration of the above embodiment will be explained with reference to FIGS. 3 to 5. Here, FIG. 3 shows a flowchart of call processing of KSU1, and FIG. 4 and FIG.
3 shows flowcharts of main processing and timer processing of the VRU 5 corresponding to the call processing of I.

First, in FIG. 3, when receiving data from the handset 4, the KSU1 performs step 101), and when the data arrives from the handset 4 (step 102), it determines whether it is a transfer request to the VRU 5 (step 103). ), if it is a transfer request, it checks the empty status of all VRU5s (104) and determines whether all VRU5s are empty (104).
05). At this time, if VRU5 is empty, KSU
1 determines whether the requesting handset receives an outside line (106), and if it is an outside call, sends data codes such as the outside call receiving number code, the called handset number code, and the transfer code to the VRU 5 (same as 106). 107), performs external call transfer processing to VRU5 (108) Also, if the requesting handset receives an extension call instead of an outside line (111), it sends the calling handset code, called handset code, transfer code, etc. to the VRU5. After transmitting the data code (112), the extension call transfer process is performed to the VRU 5 (113).If all the VRUs 5 are not empty in step 105, a busy tone is sent to the calling party. (Step 110).

In addition, if there is no transfer request to the VRU 5 in step 103, the old KS determines whether it is an end-to-end request for an extension call (see step 121), and if it is an end-to-end request, the called party The person determines whether it is vRU 5 (122) and sends end-to-end data to that VRU 5 (123). Furthermore, in step 121, if the extension calls are busy with end-to-end requests and the request is for an extension call (131), it is determined whether the called party is a VRU (132), and if it is VRU5, then After sending the calling number code to the VRU (same as 1
33), performs extension call processing. However, if there is no request to make an extension call (131), other call processing will be performed (
139).

On the other hand, in step 102, when data arrives not from the slave unit (but from VRU5), KSU1
If it is a response request, it is determined whether the external line has arrived at the VRU5 (see 142).
), if it is an external line incoming call, process the incoming external line call (143), and if it is not an external line incoming call but an extension call to VRU5 (151), perform response processing for the incoming internal call (151).
2). Furthermore, if it is a response request in step 141, KSU1 determines whether it is a transfer request (see step 161),
If it is a transfer request, the VRU 5 determines whether it is in an outside line call state (162), and if it is in an outside line call state, performs an outside line hold process (163), and transfers the outside line to another telephone (163). (164), and when an extension call is in progress, a process is performed to transfer the extension call to another location (165). Furthermore, if it is not a transfer request in step 161, it is determined whether it is a call termination request (see step 171).
, if it is a call termination request, the VRU 5 determines whether it is an external line call (1γ2), and accordingly performs the process of terminating the external line call or the internal line call (173). , 174).

Next, the operation of the VRU 5, which performs processing such as message sending and recording based on the call processing of the KSU1, will be explained using FIGS. 4 and 5.

In FIG. 4, the VRU 5 first determines whether the transmission code from KSUl is an outside line incoming code (step 201), and when the outside line incoming code is received, it receives the external line number sent from KS Old. At the same time, the transfer code and device number were received (202, 2).
03), send a response signal code to KSUl (KSUl
04). Next, when the old KS answers (205), after setting the outside line call state (206), the voice of the corresponding area registered in advance in the voice recording circuit 56, ie, the message, is played back ( 207), and determines whether or not the playback has ended (208). At this time, when a dial code (DTMF) is received during message playback (214), the VR (15) stores the dialed number (215), and when the playback ends, analyzes the dialed number. (209), and then determines whether there is a transfer request (210)
A transfer code is sent to SUl or a call termination code is sent to KSUI (211, 212). After that,
By clearing the outside line call status (213),
This operation is repeated every time an outside line call arrives.

Further, if the reception of the external line incoming call code is insufficient in step 201, the VRU 5, upon receiving the extension incoming call code (
221), it determines whether the transfer code has been received, and also determines whether the calling number and the number to be called are received.
22, 223), and upon receiving the transfer code, calling number, and called TBL number, it is further determined whether the called number code has been registered (224). At this time, if the called number code is not registered, a busy tone is sent to KSUl (217), but if the called number code is registered,
Send the response signal code to KSUl (225), KS
In response to the response from Ul), the extension call status is set (226, 227), and the voice (message) of the transfer number area registered in advance in the voice recording circuit 56 is played back (228); Determine whether to terminate (229)
.

Then, during this playback, the dial code (end-to-end)
When U5 receives the end signal (230), it memorizes the dialed digits (231), and when the playback ends, analyzes the dialed digits (233).
, and further determines whether there is a transfer request (234),
Accordingly, a transfer code is sent to KSU1 or an on-hook code is sent to KSU1 (235, 236), and if no dial code is received at step 230, the caller's on-hook operation (232
), by clearing the extension call status (23γ)
, this operation is repeated every time an extension call arrives.

Furthermore, if the transfer is not received in step 222 and the calling number is received (step 241), the VRU 5 sends the KSUl
242), and the KSU's response activates the voice recording circuit 56 in the calling party number storage area to record the message, thereby arbitrarily registering the message in its own storage area. I can do it (243
~245). Incidentally, FIG. 5 shows an outline of the timer processing of the VRU 5.

In this way, according to the present embodiment, the VRU 5 is connected to the plurality of telephone connection boards (CNm-3 to CNm) in KSUl via the lines 3m-3 to 3m of telephone lines and signal lines, and Data transmission circuits 521 to 524 and a DTMF receiver 54 with a plurality of KSU1 are provided, and the VR
By setting the connection ports CNTn-3 to CNm of U5 as system data and configuring them with data transmission and data codes similar to those of a normal key telephone from the perspective of KSU1, the VRU5 can transmit data codes and data codes from KSU1. After analyzing the data code sent to KS, in response to an incoming call from KS, a voice message can be played back based on operation data such as the calling number and called number, and then sent and recorded. Can be done. Therefore, various audio services such as message recording to VR[J, busy transfer to VRU and message playback, absentee transfer to VRIJ and retransfer from message playback VRU can be performed.

Note that the present invention is not limited to the above embodiments (
, access to the VRU may be made either by automatic selection of an empty boat using a representative extension number or by individual access. Also,
A single boat VRU may be used and is flexible.
