Description

Recording guidance device remotely controlled by interlocking with electronic exchange

The present invention relates to an electronic switch recording guide device, and more particularly to a recording guide device remotely controlled recording.

In general, switchboards such as electronic switchboards or the like are equipped with recording guide devices for informing a caller of a failure of a call connection occurring during call processing as a voice message or for broadcasting a special service related message at the request of a subscriber. The storage unit of the recording guide device includes a preset recording message, which is generally recorded by an operator of the system.

Conventionally, when an operator wants to record on the recording guide device, recording is performed by connecting a cassette tape pre-recorded in good sound quality with a switch and a phone jack located on the front panel of the recording guide device. Therefore, it can be seen that this method is a manual method of recording one by one for each recording guide device. When recording in a manual manner as described above, there is an inconvenience in that recording must be performed by the number of boards mounted. In addition, it is difficult to maintain the sound quality uniformly for each recording guide device because recording must be performed on each board in a different environment, as well as a problem that it takes a long time to set up and maintain due to excessive recording.

Accordingly, it is an object of the present invention to provide a voice remote recording apparatus of an electronic exchange that can solve the above-mentioned conventional problems.

Another object of the present invention is to provide an improved remote recording apparatus capable of recording the same sound quality of all recording guide devices in an electronic exchange.

It is still another object of the present invention to provide an improved remote recording apparatus capable of shortening a recording time by simultaneously recording a large amount of voices.

In order to achieve the above objects, a method of recording on a recording guide device of an electronic switch according to the present invention is provided in the case where a channel as a source of recording and a channel of the recording guide device are routed to the electronic switch under control. Starting remote recording by the upper processor board to the recording device; When the remote recording is started by the upper processor board, recording information on a message type and a recording time to be recorded in the mutual communication area; The controller of the recording apparatus recognizing the information related to the remote recording from the communication area, recording the size of the message to be recorded in the memory unit, and transmitting time information and remote recording information to the controller; And generating remote memory by generating a memory selection signal, a write enable signal, and an address in the control unit.

1 is a block diagram of a remote recording guide device according to an embodiment of the present invention, and

2 is an operation timing diagram of signals input and output to each unit of FIG. 1 for remote recording.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a remote recording guide apparatus according to an embodiment of the present invention. Referring to the drawings, the recording guide apparatus 100 includes an interface logic unit 10, a controller 12, a bus interface logic unit 14, a ROM or a RAM, and the memory unit 16 and a remote controller connected to the controller 12. S / P 20 to which a remote control signal is applied and the signal output from the multiplexer 18 connected to the interface logic unit 10 and the line L2 is input, and a clock and a pulse are applied. A decoder and control FPGA 24 having a REC_LAT signal changed into a parallel state through P20 is connected through a line L5, a control unit 12 is connected through a line L6, and a bus interface logic unit 14 is connected through a line L7. And a flash memory unit 26 connected to the decoder and the control FPGA 24 through a line L8, and a multiplexer 18 and a line L3. Is composed of a front panel phone jack 28, the decoder and control FPGA 24 and a nonvolatile memory unit 30 connected via a line L9. The interface logic unit 10 is connected to a time switch block 14 through a line L1 and matches 2SHW. In addition, the bus interface logic unit 14 is connected to each other through a DC line and a device processor DP (A) 34 and DP (B) 36. The decoder and control FPGA 24 and the DP (A) 34 are connected to each other via a line L10.

First, remote recording is done via subscriber lines located at the operator desk, accepting data from the original recording device, or all via SHW matching through the TSB 32. In addition, the remote recording guide device 100 transmits the announcement broadcast message to the TSB 32 through PCM data as digitized data through channel # 0 (channel 32) of the second SHW of the two SHW, and receives the data to be remotely recorded. do. The upper processor boards DP (A) 34 and DP (B) 36 report various control signals and processing results through the DC line. The controller 12 analyzes the control signals transmitted from the DP (A) 34 and the DP (B) 36 to generate information necessary for recording, reproducing, and controlling various boards. The decoder and the control FPGA 24 perform the line L6. Through the decoding of the command transmitted from the controller 18 to generate various control signals, these signals are transmitted to the flash memory unit 26 and the nonvolatile memory unit 30. The nonvolatile memory unit 30 uses 16 nonvolatile memories as a location for storing fixed messages. Up to 32 messages can be stored because two messages are stored per one nonvolatile memory. The memory unit 16 is a temporary storage location of the information output from the control unit 12 and is a place where various information such as a time related to recording and a message checksum value are stored. Therefore, even when the power is turned on again after the power is turned off, the existing information is stored in the memory unit 16, thereby enabling accurate message management. The front panel logic unit 28 converts an analog signal into a digital signal, or converts a digital signal into an analog signal to record or listen to the recording through the front panel, and interfaces with various switches and jacks.

Then, the process of realizing remote recording through the recording guide apparatus 100 as described above will be described. If the device that is the source of the recording and the channel of the recording guidance device are routed through the TSB 32 under the control of the switchboard, it is remote to the recording device by DP (A) 34 and DP (B) 36, the upper process boards. You are ordered to start recording. At this time, the type of recording message and the recording time information are recorded in the memory unit 16 through the bus interface logic unit 14. In addition, the controller 18 reads information related to remote recording from the memory unit 16 and records a size to be recorded in a corresponding message area of the nonvolatile memory unit 30 used as a data storage place for recording and board control. Time information and remote recording start information are given. At this time, the decoder and the control FPGA 24 generates a ROM selection signal, a write enable signal, and an address of a nonvolatile memory unit required for remote recording to implement remote recording.

In addition, Dx line L3 and TSB 14 via front panel P / J 28 are simultaneously connected to one multiplexer 18. The remote control signal is normally the default signal, which is a line from front panel P / J 28. That is, the Dx line is selected. Therefore, it is usually equipped with a structure to record from the cassette tape or microphone through the front panel P / J 28. However, once a remote recording command is transmitted from the DP (A) 34 and DP (B) 36, the remote recording related information is transmitted to the decoder and the control FPGA 24 by the controller 12, and the decoder and the control FPGA 24 are remote. The control signal is adjusted to connect the SHW from the TSB 32. At this time, the PCM data contained in channel # 0 (channel 32) of SHW # 1 is changed to parallel through S / P 20 and then transferred to the latch unit 22 by the REC_LAT signal and latched.

2 is a remote recording timing diagram according to FIG. 1. As shown in the figure, a REC_LAT signal is generated at the LSB time point of T. SO, and data latched in parallel by the generated REC_LAT signal is written to the nonvolatile memory block in the next T.S period. As a result, as shown in the timing diagram, the recording address of the nonvolatile memory block is generated by the record signal and the V-WR signal, and the remote recording is implemented by generating the write enable signal of the nonvolatile memory block.

As described above, according to the present invention, after recording the best voice on the board of the voice guidance apparatus using the remote recording function, the board on which the first voice is recorded becomes a source and is transmitted as PCM data to each other board in the system. Voice recording. Therefore, there is an advantage that the troublesome work of recording the voice of the same homogeneous sound recording one by one. In addition, it can save time by recording a large amount at the same time, it can be recorded directly from the home country in the remote system according to the home country, as well as can be recorded directly through the subscriber phone at the operator desk, it is very convenient in operation.
