Description

Remote recording device and method at the exchange

The present invention relates to a remote recording apparatus and method in a switch system, and more particularly, to a remote recording apparatus and method for informing a subscriber by voice, such as a dial delay and a number of a station number, when a voice service is required for operating the system.

In the conventional exchange system, the same message content must be repeatedly recorded in each PBA for recording and reproducing the voice device block, and the message is recorded using only the front panel of the PBA.

In the conventional switching system, the recording and reproducing of the voice device block (VMHC) requires a repetitive recording of the same message content in each PBA, which is cumbersome. In addition, in the case of the far-field assistance system, there is a problem that the operator must repeatedly record the same message for each of the auxiliary systems while taking the loss of time and manpower.

Accordingly, an object of the present invention is to provide an apparatus and method for recording using a PBA front plate and recording voice data through a T-switch sub-highway (SHW) in a system.

Another object of the present invention is to provide an apparatus and method for remotely recording voice data to each other in a voice device block between auxiliary systems.

In order to achieve the above object, the present invention not only records using the front panel, but also records the voice data to the recording device block through the T-Switch SHW in the system, and remotely records the voice data to the voice device block between the auxiliary systems. It is characterized by recording.

2 is a voice input control logic timing diagram in accordance with the present invention.

3 is a voice timing logic timing diagram according to the present invention;

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

The DC-BUS matcher communicates with the host processor via the Device Control BUS (DC-BUS). It selects one of the duplicated DC-BUS and performs message communication between the DP (Device Processor) and VMHC. The message exchange is performed in the following way by serial transmission method of 1 byte unit. The DP is selected by the VMHC address, and when the FS signal for MADO-3, synchronous clock and data transmission is sent to the VMHC to specify the performance mode, the VMHC receives and translates the RDY signal for data transmission and reception. The DP transmits and receives data by detecting the RDY signal.

The voice matching unit using the front panel is a matching unit that converts analog voice into digital data. When selecting and recording the message type and time of the front panel, the analog signal is converted into digital data through COMBO, an A / D converter. On the contrary, when the stored voice is to be checked in the same manner, the digital data is converted into an analog signal and transmitted.

The TSL (Time Switch and Link) Matching Unit is a part for matching with the TSL block and controls two SHWs to create a voice path. When you want to test a specific channel, make a Remote Loop Back Test Path, and when you want to test the VMHC board, make a path (BER Test Path). The VMHC receives MCLK (4.096MHz) and MFS (8KHz) signals from the TSL block and generates a time slot signal, which is used to select a desired TS. In case of remote recording between auxiliary systems, voice data is transmitted and received by TS using TSL block. The voice communication flow between the auxiliary systems is configured as shown in FIG. 1, and the voice message transmission and reception is completed under the control of the upper program.

In order to store voice messages using the front panel in the voice memory area, the address increases every frame, and the TS must generate TS that can be input every frame to store in the memory area. I need logic for that. The control logic timing input using the front panel and the voice input logic timing for remote recording are shown in FIG. 2, and the logic timing for transmitting voice to the front panel and the servo system is shown in FIG. 3.

To record voice from the VMHC of a specific auxiliary system to the VMHC of a desired auxiliary system, send a command to connect the remote recording from the upper program to the VMHC to the TS 32 data C1H command to the VM 32, and the VMHC is ready to remotely record the TS 32. The state is achieved. When the prepared result is sent to the host program as the data command of C2H, the host program sends the command value C2H data command value to send the remote voice again, and when the response command C2H value is read that the VMHC is ready for remote recording. Start recording the voice data remotely. When the VMHC has recorded the desired voice message and time, it sends the recording completion command C4H value to the upper level and the upper level program performs the TSL block and recording disconnection operation.

1 is a flow chart of voice communication control between auxiliary systems, which is a flow of communication control between a remote auxiliary system and a VMHC PBA to be recorded and an upper program. The host program requests message number and preparation for transmission to the VMHC of the remote assistance system that has been recorded, and then requests remote recording from the VMHC to be recorded. When recording is requested, the message type and recording time must be specified. When the VMHC completes the recording preparation phase, the host program instructs the remote assistance system to send a voice message and informs the VMHC of the start of the remote recording. When the recording is started and the recording is completed, the VMHC notifies the host program of the completion command, and the host program detects this and releases the message transmission completion and connection status to the remote auxiliary system.

Figure 2 shows the timing at which the input voice data is stored when using the front panel or remote recording. It is input to the first timeslot in synchronization with the system clock, MFS (8KHz) and 2.048MHz. The input serial data is latched by the serial / parallel device and stored by Write (WR) and Chip Enable (CE) signals. Voice data is stored with the address increasing every frame (8 KHz).

3 is a timing diagram for outputting voice data stored in a memory from the memory. In synchronization with the system clock MFS (8KHz) and 2.048MHz, the message of the desired time slot is output according to the Chip Enable (CE) signal. The memory Output Enable (OE) signal is always enabled per timeslot.

As described above, the present invention enables remote recording without the need to repeatedly record the same message for each recording device block by implementing remote recording in the switchboard, and is very convenient when recording on the recording device block of the remote assistance system. And it has the advantage of reducing the loss of time.
