Abstract

PURPOSE:To improve the reliability of a device, by using a static storing means such as an RAM as a voice storing means in case of automatic answering telephone service and a usual telephone service. CONSTITUTION:The 1st memory 1 to record and regenerate sending messages and the 2nd memory 2 to record and regenerate business messages are composed of elements such as RAMs respectively, and opposed to a main wire 4 and an extension 5 connected to a control part 10 and a sequential circuit 9 through a switch group 3. When an incoming is received from the main wire 4, a sending message D-A converted through a codic part 8 and stored in the 1st memory 1 is sent to a calling party and the business message from the calling party is A-D converted through the codic part 8 and stored in the 2nd memory 2. In case of calling from the extension 5, the business message recorded in the 2nd memory is sent. Since a device having a moving part such as a magnetic tape is not used for a voice recording means, the reliability of the device is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electronic exchanges, particularly those having functions such as an answering machine and a telephone service, and is intended for use with movable parts such as recorders using magnetic tape or the like as a recording medium. The objective is to provide a highly reliable product that does not require any equipment.

In this device, the messages sent and messages are played back and recorded using a recorder that uses magnetic tape as a recording medium. To reproduce the message, it is necessary to rewind the magnetic tape.

Therefore, the present invention has a memory element that can be connected to first and second memories in which outgoing messages and business messages are recorded and played back, and to connect these first and second memories to a central office line and an extension line. a group of switches, a codec section that converts the recording signal to the eleventh second memory into digital and converts the reproduced signal from the first and second memories into analog, and receives an incoming call from the central office line. At the same time, the outgoing message recorded in the first memory is converted into analog via the codec section and sent to the calling party, and the message sent from the calling party is converted into digital via the codec section and sent to the calling party. a control unit for controlling the message recorded in the second memory to be converted into analog via the codec unit and sent to the caller when receiving a call from the extension; An embodiment of the present invention will be described below with reference to the drawings.

(1) #'i Transmission memory as the first memory,
It consists of a memory element such as a memory cell 1, and a message to be sent is written in advance in the form of a digital signal. Reference numeral (2) denotes a voice storage memory as a second memory, which, like the above-mentioned voice transmission memory (1), is composed of a memory element such as a RAM, and serves to record business messages. (3) is a group of switches, and the central office line (
4) and extension (5), of which 11 (5) are mutually connected, and a memory group (
6) and the central office line (4) or extension line (5) can be connected to each other. (7) is a memo for sending calls 'JQ)
and the voice storage memory (2) are connected to the switch group (
3), the switch (8) connects the central line (4) and the extension line (5).
) and a group of switches (3), each codec (Al) to (An), (B
t) to (Bj) digitally convert the recording signal to the memory group (6) and reproduce the reproduction signal Jij' from the memory group (6).
t Analog conversion. (9) Front C self switching 1ii1 (7
) is a control section that controls the switch group (3) and the sequential circuit (9).

Next, the configuration of the control section 4 will be explained in detail along with its operation.

For example, suppose that the company to which this electronic exchange was delivered is on holiday and cannot perform normal exchange operations using the switch group (3). In this case, a message to the effect of ``J is closed today. m is the transmitting memory (1) via the switching I! (7).
The outgoing message is converted into analog via the codec section (8) and sent to the caller, and the outgoing message is stored in the outgoing message memory (8).
When the transmission from 1) is completed, the switching device (7) is switched to the voice storage memory (2) side via the sequential circuit (9)-, the signal is converted into digital data by the codec section (8), and then sent to the switch group ( 3) Start reading the message from the caller input via the voice memo ') < 2) tlCtB. Then, when a predetermined period of time has elapsed, the switching device (7) is returned to its original state via the sequential circuit (9).

In addition, if the 1liIJ#/QO detects a signal indicating that it wants to retrieve the message ta recorded in the voice storage memory (2) from the extension (5), it will communicate with the caller via the switch u(3)k. It connects the memory group (6) and the sequential circuit (9).
) Switch via! (7) tl - voice storage memory (
2), and then reads out the business message stored in the voice storage memory (2), converts it into analog in the codec section (8), and sends it to the caller. Also, the control # section OIJ is transferred from the extension (5) to the transmitting memory (1)! i
ll! If a signal indicating that the message to be sent is to be changed is detected, the message to be sent is updated to the content that is digitally converted and sent via the codec (8). Needless to say, the system 2) is configured to be able to record messages for a plurality of people depending on the memory capacity.

With this configuration, it is possible to eliminate moving parts like in a magnetic tape recording type, resulting in high reliability. Since no operation is required, 8 out of the voice 'E3tIt memory (2) can be easily accessed via the extension (5).

Also, you can easily send memo 1Jtll via extension (5).
The contents of can be updated. Furthermore, since the codec section (8) is interposed between the line between the central office line (4) and the extension line (5) and the switch group (3), the switch group (3) can perform the same number of exchange operations using digital signals. It is something that can be done.

As explained above, according to the electronic exchange of the present invention, since the first and second memories each consisting of a memory element are used for recording,
It is possible to eliminate any moving parts required in conventional magnetic tape recording, making it highly reliable, and it is also possible to easily access the contents of the message recorded via the inner 81, making it easy to operate. It also improves sex.
