Abstract

PURPOSE:To improve the reliability of speech recording information by converting a time at speech recording into a voice signal and recording the converted signal to a head of talking recording so as to recognize the time at the recording in a voice at the reproduction of the recording. CONSTITUTION:When the operator of an extension telephone set 109a operates the telephone set 109a to apply recording, the information is fed to a control section 108 via a control bus 118. Then the current time is read from a clock section 103 via a control bus 118 and controls a time switch 104 to connect a time slot 10 with a code sounded by a time stamp ROM 102 sent therethrough to a PCM highway 117 and sends the code to a recording memory section 107. When the termination of the call of an opposite telephone set 111 is recognized, the control section 108 interrupts the path of the time switch 104 to the recording memory section 107. Thus, the recording start time is recorded in voice at the start of speech recording without fail.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to a private branch exchange device having a function of recording telephone calls.

[Prior Art] Conventionally, a private branch exchange device having a function of recording telephone calls is known.

Incidentally, time is considered to be one of the most important state information when recording a single call, but conventional devices have not been provided with any means for automatically recording the time when recording a call.

[Problem to be solved by the invention] For this reason, in the past, when playing back recorded information, the receiver could not know the recording time, and the receiver often had difficulty responding to the recorder. Futa.

For example, in response to a recorded message l1. There were times when the 4Js were rude to the recorder by causing trouble to the person who recorded them due to the timing or the way they responded.

In addition, there were cases in which troubles occurred with the recorder because one-hour evidence could not be obtained.

As described above, conventional devices have the disadvantage that the reliability of recorded information on a single call is low, such as the possibility of deteriorating business transactions and interpersonal relationships.

SUMMARY OF THE INVENTION An object of the present invention is to provide a private branch exchange device that can reliably know the recording time when reproducing recorded information and improve the reliability of recorded call information.

[Means for Solving the Problems] The present invention provides a recording means for recording telephone calls, a time detection means for detecting the time at which the recording means records, and a time detection means for converting the time information detected by the detection means into audio. and a control means for causing the recording means to record the voice indicating the time produced by the converting means, prior to the start of recording of the call.

[Function] According to the present invention, when a call is played back, the recording time of the call can be known by voice.

[Example] FIG. 1 is a block diagram showing one embodiment of the present invention.

The outside line interface 101 of the private branch exchange device 100 is
It is connected to network 110 via line 112 and to time switch 104 via PCM highway 113.

Further, the extension interface 105 accommodates an extension telephone 109a via a line 119, and the PCM highway 1
14 to the time switch 104.

Similarly, extension interface 106 accommodates extension telephone 109n via line 120 and connects PCM Highway 1.
16 to the time switch 104.

The timestamp ROM section 102 is a PCM highway 1
The recording memory section 107 is connected to the time switch 104 via a PCM highway 117.

The control unit 10B is in charge of all controls of the private branch exchange device 100, and connects the outside line interface 101. Extension interfaces 105, 106,
A time stamp section 102, a recording memory section 1072 and a clock section 103 are connected.

Telephone 111 is the telephone of the other party who is the recorder, and is connected to network 110 by line 121.

The switching system of the private branch exchange apparatus 100 of this embodiment is a time division switching system, and all internal audio signals are processed using PCM codes.

Before explaining the overall operation, first, the time stamp ROM unit 102, which is an important component in this embodiment, will be explained.

In the time stamp ROM 5102, as shown in FIG. 2, PCM codes, which are the words necessary to display the time audibly, are written in each of the addresses In to 21n.

As shown in the figure, the address 1n stores the PCM code that becomes "zero" to make the number "ON" sound. Also, the address 2n stores the PCM code that becomes "zero" to make the number "1" sound. The PCM code that becomes "ichi" is stored.

Similarly, "hour" at address 16n and "minute" at address 17n.
21 types of PCM codes are stored.

These PCM codes are always PCM Highway 115
For example, "θ" at address 1n is sent to time slot O, and "hour" at address 16n is sent to the time slot corresponding to the time slot number as shown on the upstream side of 0.
is sent in time slot 15.

Next, a series of operations from call recording to playback in this embodiment will be explained.

When the other party is telephone 111 and the receiver of extension telephone 109a is talking, the voice from telephone 111 is transmitted to line 121,
network 110, line 112, outside line interface 101,
It is input to the time switch 104 via the PCM highway 113.

Since the control unit 108 controls the time switch 104 to connect the PCM highway 113 and the PCM highway 114, the voice from the telephone 111 is further transmitted to the PCM highway 114 and the extension interface 105.
and via line 119 to extension telephone @109a.

At this time, the operator of extension telephone 109a
When a recording operation is performed by the operation 09a, the extension interface 105 detects this and sends the information to the control unit 108 via the control bus 118. When the control unit 10g receives this information, it reads the current time from the clock unit 103 via the control bus 118.

FIG. 3 is a flowchart showing the operation when the read time is, for example, 10:05.

First, after reading 10:05 from the 1 clock section 103 (Sl
), the control unit 10g controls the 1-hour switch 104 to connect the time slot IO which transmits the code pronounced as "ju" of IO, which is the first information in the time stamp ROM 102, to the PCM highway 117 (S2). is sent to the recording memory unit 107 (SS).

When the recording memory section 107 receives the PCM code from the PCM highway 117, it stores the PCM code "jikuiu" at a predetermined address in the recording memory (S4).

FIG. 4 is a schematic diagram showing the contents of a recording memory in which code information is stored.

The PCM code "ju" is stored at address In.

When this storage is completed (SS), the control unit 108 controls the time switch 104 via the control bus 118, and then sends a time slot 15 to the PCM highway 117 for transmitting a code pronounced as "ji" for "time". Connect SS),
The recording memory unit 107 sends the address 2n of the recording memory to the recording memory unit 107 in the same manner as “10” (37).
The PCM code “ji” is stored in (SS, SS).

Thereafter, in the same way, "go" of "5" and "fun" of "minute" are recorded in time slots 5 and 16, respectively, in the recording memory section 1.
07 and stores it in addresses 3n and 5n of the recording memory (SIO~517).

When all the time stamp information is stored in the recording memory, the control unit 108 controls the time switch 104 to disconnect the bus of the PCM highway 115 of the time stamp ROM unit 102 and the PCM highway 117 of the recording memory unit 107. 113 and PCM Highway 1
14 bus may be maintained or disconnected, but in any case, connect PCM Highway 113 and PCM Highway 117 and record the call (S18).
.

Then, when I learned that the other party's phone had ended the call,
The control unit 108 controls the recording memory unit 10 of the time switch 104.
Disconnect the bus to 7.

Subsequently, when a call recording operation is performed in the same manner, time stamp information is stored from the address next to the last address of the recording memory stored previously, and the call recording is performed first.

In this way, the recording start time is always recorded as audio at the beginning of a call recording.

Next, a description will be given of the operation of reproducing the call audio recorded as described above.

FIG. 5 is a flowchart showing this reproduction operation.

First, when you perform the playback operation on extension phone 411109n,
The extension interface 106 detects this and sends the information to the control unit 108 via the control bus 118 (S
21) When the control unit 10g receives this, it controls the one-hour switch 104 and connects the PCM highway 117 and PCM highway 116 of the recording memory unit 107 (S2
2) When this connection is completed, the recording memory section 107 is driven to read out the stored PCM codes in order from the smallest address and send them to the PCM highway (S23).

When the extension interface 106 receives the PCM code, it performs D/A exchange for the analog extension telephone, converts it into an analog voice signal, and sends it to the extension telephone, and sends it as a PCM code to the digital extension telephone. , converts it to sound by D/A conversion inside the extension telephone (S24)
.

This allows the operator to record a recorded message with a timestamp, in the previous example, rlO: 5 minutes, Hello...
” can be heard.

The above explanation is about the case where the recording operation starts from a call in progress, but there are also other cases where recording is started from the beginning, such as when using an answering machine, and the recording is automatically time-stamped before the recording starts. .

[Effect of the invention 1 As explained above, 1 According to the present invention, 2 The time when a call is recorded is converted into audio and recorded at the beginning of the call recording, so that the time at the time of recording can be known by audio when the call is played back. This has the effect of significantly increasing the reliability of call recording information.
