Abstract

PURPOSE:To receive services of a pushbutton telephone also by a dial system telephone by detecting pulses to be dialed by a caller and by sending out push- phone signals in correspondence with these pulses into voice mail, etc. CONSTITUTION:A subscriber 21 makes a call from a dial system telephone and dials telephone numbers assigned to a VMS27. PBX, after detecting the call, speeds up a scan period of an LC22 from 96ms to 8ms in preparation for the dial pulse detection. The PBX, when detecting dial pulses, connects the caller and PBOS25 respectively to the VMS27 according to the telephone numbers.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a dial signal/PB signal conversion method for converting a dial signal into a telephone signal in a switching system having means for scanning a subscriber circuit to detect dial pulses. It is something.

(Prior art) In recent years, as part of office automation, calls made while you are absent are temporarily stored (absentee reception), and voice mails and messages from callers are sent to you at a time specified by the caller. Increasingly, voice mail is connected to a private branch exchange (hereinafter referred to as PBX) for the purpose of sending a message to a recipient.

As shown in Fig. 1, a normal voice mail (VMS) 13
is used by being accommodated in the subscriber terminal of PBX J 2 in the same way as subscriber 1. When using the voicemail 13, the subscriber 11 sends the voicemail 13 a service code specifying the requested service and the subscriber's name. How can I make Voicemail 13 recognize that I am a member of Ismail 13? Is it necessary to send a password (identity verification coat'') etc.?

Conventionally, PBX 12 does not have a dial/gurus relay function after setting up a call route, so subscriber 1 needs to use a telephone to fully access each code, and voicemail 13 It was also operated by the Puno 7 ehon signal.

For this reason, the voice mail 13 can only be used by subscribers of a button telephone, and cannot be used by subscribers of a rotary telephone.

(Object of the Invention) It is an object of the present invention to solve the above-mentioned drawbacks and to make it possible for rotary telephone subscribers to fully utilize systems exclusive to private telephone subscribers, such as voice mail, in the same way as subscribers to private telephones. This provides a dial signal/PB signal conversion method.

(Structure of the Invention) The present invention is an exchange system having a means for scanning subscriber circuits to detect all dial pulses, and which is usable only by terminals that use a F07 dial pulse signal as a selection signal. (hereinafter referred to as system A) and an f7 Nyuphone signal transmitter are connected, the system Ai is called from a rotary telephone. Detect and connect the rotary telephone and the system A1 with the system A and the touch-tone signal transmitter, respectively, and in the connected state, detect the dial/gurus corresponding to the service code sent from the rotary telephone. This is a Zossy signal/PB signal conversion method, which is characterized in that a P, 7 yohone signal corresponding to the detected dial pulse is sent from the yush phone signal transmitter to the system A.

(Embodiment) FIG. 2 is a block diagram showing an embodiment of the present invention. Second
In the figure, 21 is a subscriber authorized to use the voice mail CVMS (CVMS) 27, and 22 is a PBX subscriber circuit (L).
C), 23 is a scanning device (SCN) that performs scanning to detect subscriber call status such as dial pulse and disconnection detection after call completion, 24 is a time division channel switch (SW), and 25 is an f7 system phone. Signal transmitter (PBO8
), 7? t; is the PBX control unit (CPU), 27
is Z Ismail (VMS), 2g is subscriber 21 and VM
Connection train with S 27, 29 is VMS 27 and PB
This is a connection train with O825.

The dial pulse from the subscriber 21 (dial telephone subscriber) is detected by the LC 22.

That is, when subscriber 2 turns on the telephone,
The SCN 23 scans at a faster rate (eg, 8 milliseconds) than the scanning points provided on each LC to detect and count dial pulses. If the number of dials and calls is detected and removed by photons, it is only necessary to detect disconnection after the call is completed, so the SCN 23 changes the scan point lath scanning period (hereinafter referred to as the scan period) to a slow period (for example, 9
6 milliseconds) and the PBX CPU
We are trying to reduce the load on 26 people.

Also, when subscriber 21 talks with VMS 27, subscriber 21, PBO 825, and VMS 27 are connected in chronological order by connection train 38 and connection train 39 in 5W24, but PBO 825's Since the input section is of high impedance, the message of the subscriber 21 is sent to the VMS 27 without transmission loss.

In Figure 3, subscriber 21 (dial telephone subscriber) is using VM.
It is a figure which shows the usage procedure when registering a message in S27.

The operation of the embodiment shown in FIG. 2 will be described below with reference to FIGS. 2 and 3.

In step 1 shown in FIG.
Dial the phone number assigned to 7. When the PBX detects the call, it speeds up the scanning period of the LC22 from 96 milliseconds to 8 milliseconds and dials the call.
Prepare for the detection of viruses.

When a dial pulse is detected, the caller and the PBO 825 are respectively connected to the VMS 27 according to the telephone number. Connection trains 28 and 29 shown in FIG. 2 illustrate this connection. The PBX then prepares for detection of the next dial pulse. Once the call path is established, the VMS 27 sends the caller a guidance message: ``Please enter your registration number.''

In step 2 shown in FIG. 3, the caller dials the registration number according to the guidance. PBX has this dial all L
C22, and the file 0. corresponding to the registration number is detected by C22. / Yuhon signal "i" is sent from PBO 825 to VMS 27 via connection toton 29. VMS 27 receives the registration number by the Pu/Yuhon signal, and the caller
After confirming that the caller is authorized to use the service, the system sends the caller a guidance message: ``Please enter the entire service code.''

In step 3 shown in FIG. 3, the caller dials the entire service code (eg, time-specific delivery code) according to the guidance. The PBX detects this service code fLc22 and sends a signal corresponding to the service code.
i PBO 825 to VMS via connection train 29
Send to 27. When the VMS 27 receives the service code from the pushphone signal, it sends the guidance to the caller: ``This is a time-specified service. Please enter the time.''

Similarly, in steps 4 and 5 shown in FIG. 3, the caller dials the service code (time, message delivery destination) according to the guidance, and the PBX transmits each of the service codes to the VMS 27 by translating the service code into the FU07N Yuhon signal. Send to, V
The MS 27 sends a guidance message to the caller, and a conversation proceeds between the caller and the 7MS27. After completing step 5, there is no need to dial or receive calls from the caller, so the scanning period of SCN 23 is 13m5.
The speed will be reduced to the normal 96m5.

In step 6 shown in FIG. 3, the caller sends a message to the VMS 27. The VMS 27 converts the message into a digital signal 1, for example, an ADPCM code, and stores it in a file memory (not shown). On the other hand, the PBX monitors the disconnection after the call is completed using the LC22.

In step 2 shown in FIG. 3, when the caller finishes sending the message, the PBX hooks down the rotary telephone and completes the message registration.
27 that the message reception has been completed. 7MS27
Upon receiving this notification, the terminal ends storing the message in the file memory.

In the above embodiment, the conversation between the caller and the VMS 27 uses all the dialed digits, or the number of digits for the registration number and recitation code usually requires 5 to 10 digits, whereas the PBX's extension phone It is sufficient for the number digits to be about 2 to 5 digits, and there is a considerable difference in the number of digits between the two. However, the registration number and recitation code.

The dialed digits required for conversation between the caller and VMS 27, such as the service code, are detected by SCN 23, which scans at a cycle of 8 milliseconds via LC 22f after the PBX establishes a communication path between the caller and VMS 27. , since the PBX detects this only after the call path is set up, the PBX side cannot distinguish whether the dial is a failed dial for a normal call route connection or a false dial for a conversation between the caller and VMS 27, resulting in a malfunction. There is no need to worry about doing so.

As explained above, in this embodiment, the dial pulse dialed by the caller for conversation with 7MS27 is detected by the SCN 23 via the PBX's LC22, and as a result 'j
5' PBO825 to f, 7MS27 with Nyuhon signal
Therefore, even if the caller's telephone is a rotary telephone, he or she can receive voicemail service in the same way as a subscriber to a Zossiphone telephone.

In the explanation of the above-mentioned embodiment, the case where the caller uses a rotary telephone to register a message in the voicemail is explained as an example. The same applies to so-called confidential services that deliver messages after confirming the identity of the person. In this confidential service, the recipient may be requested by Ismail to send a subscriber number for identity verification, or to send the subscriber number and code to all voicemails, but in the case of the message registration service mentioned above, The called party just dials those codes, just like the caller does.

Furthermore, in addition to the above-mentioned Dismail, there are order entry systems, database/systems, etc. as systems that allow services to be received using a 7°7no Yuphone telephone, but according to the present invention, any of these services can be provided using a dial type telephone. It becomes possible to receive it.

(Effects of the Invention) The present invention detects dial pulses, which are dialed by a caller or a callee for conversation with a voice mail, order entry system, database system, etc., using a scanning device through all subscriber circuits of a PBX. The voicemail/order entry system 7' sends the F07/Yuhon signal corresponding to the detected dial/gurus from the touch-tone signal transmitter to the voice mail and order entry system.
- Since the system transmits 7 stems, etc., it is now possible to receive the services of the above-mentioned systems, which were conventionally available only through telephones and telephones, also through dial-type telephones.
