Abstract

PURPOSE:To simply and economically realize the recording of voice while talking by providing a voice accumulating device connected to a meeting trunk through a time division multiple switch in a time division electronic exchange having the meeting trunk. CONSTITUTION:When a subscriber records the talking voice at the time of the extension mutual connection or the trunk line or exclusive-use line connection from an extension telephone set 109, beforehand, a voice accumulating device 110 is called from the extension telephone set 109 and the recording condition of the voice message is set. After the called side is called by re- grasping a close register 107 by the hooking of the extension telephone set 109, the meeting trunk is grasped by the re-hooking of the extension telephone set 109 and the voice channel is formed by three parties. In such a condition, the voice while talking is accumulated in the voice accumulating device 110. When the recorded voice is reproduced, the device 110 is called from the extension telephone set 109 and the reproducing condition of the voice message is set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a voice storage system for a time division electronic exchange that exchanges and stores voice into digital signals.

[Prior Art] Conventionally, in the voice storage method of this type of time-sharing electronic exchange,
The configuration was as shown in Figure 2. That is, a central office line trunk 204, a leased line trunk 205, a conference trunk 206 . In a time-division electronic exchange 201 having a time-division multiplex switch 202 that accommodates an input register 207, a subscriber circuit 208, etc., and whose connection is controlled by a central control unit 203, voice during a call is transmitted by a telephone 209 connected to a subscriber circuit 20B. When recording, a configuration has been adopted in which a recording device 21O is externally connected to the telephone 209 using a telephone pickup or the like.

[Problems to be Solved] However, in the voice storage method of the conventional time-division electronic exchange described above, when recording the voice during a call with the telephone 209 connected to the subscriber circuit 208, the telephone 209 is equipped with a telephone pickup, etc. This is because the recording device 210 was to be connected externally.

This required an external recording device for each subscriber who wanted to record the voice during a call, which was extremely wasteful.

[Means for Solving Problems 1] The present invention has been made by focusing on the above-mentioned conventional problems, and provides a time-sharing electronic switching system that can easily and economically record audio during calls by using conference trunks. This paper aims to provide an audio storage method for

To this end, the present invention provides a voice storage device connected to the conference trunk via a time division multiplex switch in a time division electronic exchange having a conference trunk, and when interconnecting extension lines, central office lines, or dedicated lines/extension lines. The present invention provides a voice storage method for a time division electronic exchange that stores voice signals via the conference trunk.

[Example] Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a system configuration diagram showing an embodiment of the present invention.

In FIG. 1, when compared with the system configuration of the conventional voice storage method embodiment shown in FIG.
Instead of the external recording bag 210 connected to the external recording bag 210, a known voice storage device having functions such as storage and retransmission of voice mail, proxy reception, delivery, and rounding is installed on the single output highway of the time division multiplex switch 102 in the electronic exchange 101. The feature is that the device 210 is connected. When a subscriber records voice calls from the extension telephone 109 when interconnecting the extensions or connecting to a central office line or dedicated line, especially when making a call from the extension telephone Ja 109, as explained in Example 11, the voice recording device 110 records the voice from the extension telephone 42109 in advance. to set the voice message recording status.

Then, by hooking the extension telephone 109 and recapturing the input register 107, the called party is called, and then by hooking the extension telephone 109 again, the conference trunk is captured and a three-party voice communication path is formed. In this state, the voice during the call is stored in the voice storage device 110. When the called party recovers, the conference trunk is disconnected and only the calling party's extension and voice storage device 110 are connected, so the voice message recording state is released from the extension telephone [109] and the call is terminated. When reproducing the recorded voice, it is sufficient to call the voice storage device 110 from the extension telephone 109 and set the reproduction state of the voice message. The above has been explained using an example of a call from an extension subscriber. However, when a call is received from a central office line or private line, the telephone extension telephone 109 is hooked when the call is received, and the central telephone line or private line side is temporarily put on hold and the voice storage device 110 is called. to set the recording state, and then record the voice during the call by following the same procedure as described above.

The configurations other than those described above are the same as the configuration shown in FIG. 2, so the explanation will not be repeated.

[Effects of the Invention] As explained above, the present invention provides a voice storage device connected to the conference trunk via a time division multiplex switch in a time division electronic exchange having a conference trunk, and connects internal lines and central office lines. Or, since the voice storage method of the time-sharing electronic exchange is used, which stores voice signals via the conference trunk when a dedicated line or extension is connected, voice mail storage, retransmission, proxy reception, etc.
By connecting a known voice storage device having functions such as delivery and rerouting functions together with a conference trunk, it is possible to easily and economically record the voice during one call.
