pJ, Returning to Figure 2, the echo canceller device is connected to the J port (= I don't understand that J and N are prepared in one form. Each device has 220 1 (one voice sample value is exchanged between the echo canceller and the echo canceller) A plurality of latches 222 to 224 and a tone T2ζ bridge processor 20 0:ti (the milk control register 221, L) under I control.

In the assigned time slot, the echo canceller performs From the time division multiplex data bus interface 202 to the demultiplexer 207 and A near-end audio sample is received via latch 222 and a demultiplex signal is received from the switching device. A far end audio sample is received via multiplexer 225 and latch 223. workman Cocanceller 220 calculates an echo estimate and subtracts it from the near-end speech samples. . The result is sent to switching device input lotus 208 via latch 224. reactor. The audio samples from the switching device are transferred to the time division multiplexed data bus 133 and interface, 202Y to send the LC time slot input to the change device.

Transmission and reception of time division multiplexed data 133 The input signal is input from the time slot 256 for communication with the switching device 124. Pass PCM audio data. However, audio bridge boat + 'J'-64 Times Only lottos are available. Therefore, interface 202 is an audio bridge port. c-) Select 64 of the 256 time slots that you need for the Echo canceller, voice detection to format data and send and receive data clock signal generation for devices, delay devices, and switching devices.

The audio detector 204 shown in FIG. 2 is connected to a digital signal processor 216. Shift register 213 and 214, output shift register 218 and audio It also serves as a signal register (latch) 219. Is the audio ejector an echo canceller? The flow of data from the YF to the switching device is simply a switch rather than a YF change. data on both input and output fills of the programming device, i.e. buses 208 and 209. monitor the flow of data. This allows the voice bridge processor to increase the amount of voice data. Changes such as reducing the thickness can be completely controlled, and the bridge can also be partially changed. It should be able to work even if the voice detector on the phone is not working.

The digital signal processor 21G processes the time slot assigned to the audio detector. The audio detector receives a synchronization pulse within the target and switches on as soon as the pulse is received. shift register 2 from the input and output lotus 208 and 209 of the switching device, respectively. 13 and 2114 and multiplexer 215, start reading data 7 alternately. reactor. During step 1 of the program, the digital signal processor immediately adjusts the audio level. to output shift register 218 and latch 219. Periodically the audio is blurry. The digital signal processor scans the digital signal processor to determine the presence or absence of audio. , reads the audio level value from the latch, if present.

This data is then transmitted via data bus 2121'Y multi-break number 210. A multiplexer buffers the data from this audio detector.

The audio bridge processor connects the digital signal in the audio detector via the transmitter 211t. control signal processor 216; By setting register 21γ, The digital signal processor can be used in any J mode of many operating or maintenance motes. You can put it on the card.

The switching device 205 performs three main functions in the conference device. ¥7 +: In order to create output sample values for each conference participant, By adding together the audio sample values from channels 1 and 2, we create 7 values for the conference in Some 1. In addition, we perform noise-controlled S1 automatic level control on the input audio sample value, and 7. If the echo canceller is not enabled, the loss occurs when the speaker's receive path is switched on. 1. Echo control can be realized by the 1-rotation. 1-X Voice Fritsushi Processor 20 Is 0 an appropriate coefficient for the coefficient memory of the switching device? Niteko to write Of these (not all).

The conference addition operation is a two-stage process that occurs in two time frames. A frame consists of a maximum of 64 -1-1 voice frissi time slots. −Rierere First, make the summation for each meeting without omitting the sample values of the voices for the time frame. Don't mix it up. Then in the next timeframe, from the conference sum to the conference By extracting the true value of the participants' vocalizations, we can create sample values for listening.

This process involves two 1ψ crops in parallel, but two different time frames. This allows for pipeline construction as occurs for system data.

The switching device used in the unfired J Heaven Mlv example is shown in more detail in Figure 4. Stop. The switching device switches the output of the echo canceller. I received it with Has208-hi. The data is in the well-known 8-hit parallel format of μ255. Ru. This data (except for table read operations) The data is converted into human linear form and the linear data is sent to a manual multiplier 404.

The human power unit 404 is a voice bridge that realizes sound control and automatic level control. Ru. Two inputs to one device (A, sample of linear utterance from converter 400 Values and coefficients memory 402 determined by the audio bridge processor 200 and the coefficient from . The coefficient should be increased in certain cases and decreased in certain cases. be. Since conference participant 1 does not make a sound, the coefficient is O for that time slot. Eliminate the hackkland noise associated with the cut.

Multiplier and indirect (overflow circuit) to ensure that the C coefficient is correct. 417 detects a product greater than the value allowed by the bridge. "Afuri, Joi" is the prosecutor's office. output forces the output to the maximum level corresponding to the sign bit of the output. Ha, lo.

The output of the overflow circuit 41γ is the same as that for each frame. 11. Apply force to the subtractor and subtractor to produce the sample value taken; 11. reactor. addition and subtraction t'', memories 403, 407 and 409 are used This is done by device 408. When I was making a sum for the meeting, G':l 3. The logical operation unit 408 calculates the adjusted utterance sample value of the human multiplier 404. utterances from all timeslots within the same timeframe of a particular conference. Add 1 to the partial sum of the meeting, which is the sum of the sample values. The partial sum is stored in the sum register 411 and Stored in accumulator memory -407 via multiplexer 412.

To create a listening sample for each conference participant, The voice accompaniment value is retrieved from the memory 409, and the voice 741 from the same flume in the conference. Subtract it from the sum of sample values.

From the second point of view, the conference accumulator has two blocks of memory data. i.e., the partial sum of the utterance sample values of the current frame and those received in the previous frame. It includes the sum of the utterance sample values and 7.

Coefficient memory 402, control memory 404, accumulator 407, and voice Addressing of sample value memory 409 is based on time slot and frame counters. Be controlled by the circuit. of data associated with each time slot in memory. The flock is connected to the input and output time slot counters via multiplexer 416'& 418 and 419. Utterance sample value memory is Since it contains two data blocks for each time slot, the frame counter 4 20 is used to address a given data block. Accumulator 4 07, the phase adder 421 responds to the frame counter for each time slot. address one of the four data blocks associated with.

As mentioned above, the audio bridge processor receives information from the NSC processor 101. Each conference is controlled by participation rights based on the order of The processor 200 also controls the number and level of simultaneous speakers. audio bridge processor The server performs this control by using control memory 403 and coefficient memory 402. Now.

The control memory 403 consists of 64 words, each word corresponding to a conference port. That is, it is related to the time slot. Control memory is buffer 413, block Audio bridge via RAM address register 424 and multiplexer 415 For each time slot, the zero word is written by the processor 200. Keep the address of the conference accumulator associated with the Muslot. This way so that the time slot sample value is added to the partial sum or subtracted from the sum. The sample value in accumulator 407 is stored in control memory 403 whenever calculation is performed. That's the point.

Coefficient memory 402 should contain two words per time slot. one word corresponds to the input coefficient for adjusting the sample value of the speaker, and the other is sent to the participants This is to adjust the sample value of the listener.

The output of logic unit 308 is sent to the conference participants in difference register 414 and Send to output multiplier 405 via deflection circuit 410. Multiplier 405 adds by the coefficient factors received from memory 402 to provide additional echo control. Adjust the listening sample value. Similar to the input operation, the overflow circuit 406 inputs a level of listening samples. The output circuit 401 outputs the result as μ2. Convert back to 55 format 1. reactor. Compressed body ÷ J is the output lotus of the switch device. 209 via the time division multiplex data bus interface 202 in FIG. be sent to multiplex data bus 133. This data bus and NSC time slot input The voice sample values obtained through the di-calculation are distributed to the participants of the communication network ten-go conference. reactor. Now that we have talked about the bridge hardware, the flow of data through the bridge Please give a simple explanation of 1i, I'a: I'll take care of it. During each time frame, 64 Imslot's]) CM data is transmitted via the time division multiplex data bus 133. r　7'・Enter the bridge 7). The data of each time slot is -1 and looks like 203 Second, send it to an echo canceller and perform various levels of echo suppression there. De The data exits the echo canceller device and is sent to the switching device, which The sum of the data is taken and the result is distributed to each port of the combination request meeting.

For each of the 64 boats (i.e., time slots, channels), 1-7. ) The voice detector monitors the data entering the switching device and determines whether there is voice or no voice. Generates a ti1 indication (medium/vacant) and an estimated audio level value. sound like latch 219 The number of 8 hits in the voice level register is the voice level estimate 5jl value, more specifically the point The signal processor represents the energy level of the Generate silent instructions. Voice bridge processor with gamma cooing voice/without sound de1 I) Detector for each sound for each base cycle to obtain instructions and audio level estimates Scanning 2. . Then they can see which ports of the conference are enabled on the bridge. (Used by the conference processing block to select the The sample value from the port will be included in the resulting output sample value if it is distributed to each port of the conference participants. Let's go.

4. Data bridge system The data bridge portrait is shown in a more complete form in Figure 6. Shown in Figure 6 As such, the Cheetah bridge 135 is connected to the data bridge processors 600 and 601. A plurality of data link processors, a buffer memory 603, and a It consists of a sequencer 604. Each data link processor has a port such as 608. A plurality of 602-like ports are associated with the data interface. to explain In this example, eight data link processors or Each data link processor supports a total of 64 data bridge ports. It is configured to serve eight ports.

The data bridge consists of two buses: a serial control bus 134 that handles control functions, and a data bridge that handles control functions. interface with the network service complex via two time-division multiplexed data buses. has an interface.

[flijl　6IT] Access to the lotus 134 is as follows: NSC processor 10i t' (IjJ1 is made with Futakami as a slave) /! , ) is determined using a device such as data bridge 135. Each slave It has a dedicated interrupt terminal 7 and can be used to send signals to the mask when you want to use the slave or bus. The mask sends a signal to each slave to stop the slave from operating on the bus. It has a continuous cut-off terminal.

The one-layer multiplex data bus 133 carries bit-parallel, word-serial bidirectional data. Tabas has 256 channels at a bit rate of 64 kb/sec. 6.1 The data channel (i.e., one on the data bridge port) is The other channels are provided to the bridge and the other channels are taken by the audio bridge conference system. Used by other slaves such as stores etc.

For illustrative purposes, customers using Cheetah Bridge (at least two different stones) Assume that the communication mode is communication 1-ro with monthly 1u-te & 14 trunk line-1-. Therefore, A7) Install a trunk line for half-duplex connection of 4.8 kb/sec for xjfi customers. Why don't you use it? ;) If the customer supports a full-duplex connection with a take speed of 56 kb/sec. The authorities decided to use the relay line.

These modes of take communication are unique to each data terminal and cheater free. Requires different sequences of signals between devices. However, bridges can be connected to any trunk line. Transparent to different terminals due to ability to match take speed and signal do.

Explanation 1: For the sake of clarity, data terminals are networked to CCI TT. 1 Assume that you communicate with Cheetah Bridge using a protocol. b) Spirit of the Chirun invention It is well known in the art that other data rates and protocols within the range of It would be obvious to anyone.

The proposed Group 1v protocol is a seven-layer protocol, all of which The level of Cheetah Bridge is not intended to be used exclusively. Level 1- is data Mechanical and electrical equipment used to establish, maintain, and break circuits between terminals and switching equipment. , does not exhibit functional and procedural properties.

This level can be used to specify full duplex (or half duplex operation, synchronous or asynchronous operation, etc.) do. Level 2 is called the “link layer” and covers initial operation, error control and Flow control handling, trench level 3 is not achieved with the Cheetah Bridge of this example. I haven't, but it is possible.

Level 4, which we call the ``transport level'', is a single interface. Optimize the use of accessible communication devices. This is a route selection command, etc. ? include.

Level 5, on the other hand, can be called the session layer) 17. Communication between two end devices Establish, manage, and transmit information. In other words, the 12 terminal devices are based on the device type and terminal type. Information must be exchanged regarding capabilities related to characteristics. In order to ensure that data bridges are used only for facsimile machines or for conferences, Assume that

Level 6 of the protocol is called the "document layer," and includes data types, encryption, and , key 1.・The document structure is defined as 5 and has a level 7 protocol. (Good; it's defined by Tll users, so there's no discussion about it.

Now, returning to the explanation of the device shown in Figure 6, the Cheetah Bridge processor 6001 and the main controller It is a processor. Sowa 5 is connected to NSC Pro via series f7ilJ Ceramic Hass 134. It has an interface with sessionor 1o1 and receives conference configuration information from it. Report the status of the meeting.

Additionally, the overall maintenance capabilities of the data bridge are controlled by the Cheetah Bridge processor. It should be done in person.

Each take link processor is commanded by a data bridge processor 600. In order to control the port configuration in the same way as the port 602 Verta port data interface and interface from there 58 It can receive kb/sec serially and also interface with motem like Mochimura 07. Hold the face and receive 4.8 kb/see from there.

The board is connected directly to one buffer memory in a time-sharing manner via 611 communication hubs. To take a contact face, the related take link processor control W+ The information sent to the conference participants over the network is read from memory by 11) Insert a take received from a participant into memory.

The main modules of the data bridge shown in Figure 6 are further illustrated in other figures. 71゜A description of these modules is firstly shown in FIG. Let's start by explaining the port 602.

Port 602 outputs a high voltage level in serial form at a data rate determined by an external clock. Transmit/receive link control frames. In this example, two types of themes are used for explanation. ta fast reaction, 4.8 kb/sec L-yτ)" 56 kb/se+- I'll just think about it. The water boat is the information part of the frame (Kotsui Tei 3 5° σ) Communication between the boat and the data link processor.

This is done via shared memory 7.

If a short time slot argument is used as leverage, reading or writing will be , based on the read latch signal or the paste latch signal. old When the insert latch signal is set, writes to the shared buffer memory of When a time slot occurs, the lower eight hits of the address and the received data byte are Following this, the top 16 hits of the address are strobed onto the communication lotus (611). . After that, the write latch signal (d is automatically cleared.A similar operation is performed on the shared buffer. This also occurs when reading from the file memory.

Port h (602) shown in Figure 7 also has control and status registers (709). ing. Control registers are local port controllers (700) or data links. The register can be set by the processor (701) selectively set to make it live. For example, the data link processor When the \\disconnection hit in the register is set, the port fii control unit is activated.

A status register reports the status of each raccoon device in the port. I have some configurable settings for this. 〜＼Tishital〃〃 The name indicates the data rate received by the port by the port data interface. The status register is set to indicate the read status to the shared buffer memory. There are other conditions that indicate that a disturbance has occurred.

The port data interface (60B) is shown in more detail in Figure 9. I will explain from Koga 1. In the implementation used in this example, the port cheetah interface functions with eight port devices (602) such as the port (602) shown in FIG. do. The port data interface supports different transmissions used by conference participants. interface with ports and time-division multiplexed data buses; Let's perform the functions. As mentioned above, 7.3>+1+H objective/component ((, participants is a 48 or 56kb7':see network channel. It is possible to communicate using a network. Port data interface (608) uses time division multiplexing The toll exchange (1 (1) 2) A network with a speed of 54 kl/s that is compatible with standard T' trunk lines in Service complex time slot switching device frame (124) (Fig. 1) Send and receive data over time. Accordingly, the data speed of 1゛] on the communication/X bus (611) 8 human data (4.8 kb/sec each participant channel) Kai iJ', 56 kbAec will be played with on any of the participant channels.

5. For Fi kb, 43c participants, the port data interface is Remove the number bit and communicate the data of 8 hits<611)J- in parallel form Convert it to serial form and connect it to the speed selection interface in port' (602). Directly to lead (922) l to the device. Network soil 4.8 kb/ ’;, for a participant transmitting at a rate of ec, the 8 hit data bytes are serially converted and the codec (920) is transmitted. Kochitsuk (920) is series P Convert CM information to analog signal and send analog signal to modem (607) (shown in Figure 6) Send to. The modem (607) converts the analog signal back into digital form. , this cheetah stream is sent to the speed selection interface in port (602) do. Then, as mentioned above, port i-J: Renka Has (611) and time sharing A multiplex data bus (133) is used to write data into the shared buffer memory. Say a proverb.

Therefore, the sharing after being handled by the port data interface and the port The data stored in the buffer memory is based on the data rate used by the participant terminal. For all participants, regardless of the

This data is then sent to any participant, so that participant port (by which it is retrieved from shared buffer memory) at the data rate. .

The port data interface (608) shown in Figure 9 is a data link processor. Hass (6101r = Has 7 control registers that can be accessed directly from Vt) These registers are used to select the data rate conversion and the data link processor (60 1) Controls the transmission of free coats on free channel F indicated by 1).

The receive data register (904) and the transmit data register (907) are communication hubs. (611), respectively used to write and read data. This is an 8-hit register.

The other registers are formatted so that each register has one bit for each port. Each register corresponds to the following functions for the port: Resistor DIG/ANA (906) determines the bit rate at which the port sends and receives. It has the value of port m specified, and the port is stored in register DATAPORT (911). A human input per boat that enables or disables serial data sent to and received from ports. The register MODES (905) has received data of 56 kb,':e, It is a read-only register that has a value for each port that indicates whether it is an EC or not. Register TPSDCBIT (903) has one hit for each port and is 56 kb. /see the 8th hit of each hide in the cheetah stream or time division multiplexed data hash -42, register READREG (910) is sent to the port If a port is drawn and a port is set, time sharing for that port is performed. The contents of the multiplexed data are read into the receive data register (904).

The operation of the boat data interface is such that conference participants receive 56 kb/sec of data. How does the Boat Cheetah Interface transfer data when using a computer terminal? Whether it is used or not, the data is handled at a port and the data is handled at 64 kb/sec. Explain whether data must be transmitted to or from a multiplexed data bus. You can understand it better by reading it.

The data link processor has port 1- (602) with 56 kb/sec data Set the DIG/ANA register (906) to indicate motor speed mode. Suppose you want to send an instruction to the port data interface to read the command. communication 8 parallel data received from the time division multiplexed data bus via the HAS (611). The parity of the data is checked by the parity 1 check circuit (918), and the parity of the data is checked by the parity check circuit (918). Shift to digital data shift register such as (901) corresponding to 02) be done. A signal bit that tells the far-end terminal whether the controlling mote is a data mote. is removed from the input signal and the remaining 7 signals are connected to the port via conductor (922). It will be lifted and removed. At the same time, the serial data from the port i4 register (901) After being shifted and collecting 7 hits, the signal hit is added to it and the 8 bits are is rolled into the transmit buffer (915). to an appropriate time slot count value. The buffer (915) is unloaded and the buffer (915) is from the far end Njli1 on the divided multiplex data bus via a time slot switching device. Data is sent to -IL.

``J No. hi]・instructs the mote of the channel.For more details, , B voice +-1 ~ the human changes from O to 1 and vice versa, but the tintal day In Tamoto, (d) is a continuous stream of 1s, and a stream of 0s (-stream is sent to instruct the national control mote.

The person who received the first call (H'7-) is either in data mode or itj control mode. A number of juices are used to determine whether the Sent to Kubrosetza.

Each button where the respective hits of registers (906) and (911) are together Specify the state of the root. Therefore, there is an O in the D engineering G/ANA register (906). ] is the channel or 56 kb Acc or (l 4.8 kl) Ae Indicates that it is a c-mote. In addition, the port is 56 kb/sec mote. This is controlled by O or 1 in the DATAPORTlz sister (911), respectively. Indicates whether it is a mote or a data mote. C:, transmit table on control mode Everything that is routed to the data register (907) is sent out on the time division multiplex bus. However, the data mote sends out serial data from the port.

The original port data interface of the data link processor controls the data conference There are three general sequences to go through to set up and terminate a connection with a participant. monitor to determine whether the far-end (i.e. participant) terminal is the controlling mote or not. Executed. In this Shi-goonsu, the meeting estrus's wife Sei-zi-ro is The transmission of the far end terminal through the time slot switching device of the bus complex. It is connected to the double-edged tract. Port Cheetah interface is same time slot The far end terminal is connected only to the receiving path from the terminal through the reception device, and the far end terminal is ￥i1 ↓Since it is a ton'lY3 mote, it falls into the control or voice mode. , does not enter data mode.

The monitor sequence is the data link processor's response to the port cheater interface. It is activated when you set it to read data from a time division multiplexed data center. this is By setting a hit to port (602) of register (906). achieved with a data rate of 56 kb/see on the port Cheetah interface. Set conditions to receive data. Also, the data port (DATA) I) The ORT' lucister (911) de-energizes the serial data from the port and stops sending it. so that the output of the communication data register (907) is transmitted on the time division multiplexed data bus. Set for this port to

The contents of the receive portion of the time division multiplexed data bus are then stored in the receive data register (904 ), and the software counter indicates that N control motes are free. is set to count the number of tight slots created. New every 125 ms When Hyde enters register (9,,04), control mote free character is found. If not, it means that the far end controller 1 is not in digital control mode.

Each time a control mote free character is detected, the counter is incremented and the Cheetah +C 8 consecutive hides before Ridge determines that the far end is the controlling mote Must be received; 11. Must not be. When it detects that the port is on the controlling mote , the wait monitor success response is taken by the link processor and the cheater is stripped. 'Reported to the location sensor.

The connection sequence of events is the data when configuring the port that joins the conference. The operation of the link processor and port data interface will be explained. this The sequence begins by executing the monitor sequence described above. It's a trench - Link processor sends free bytes to ft1lJ to I mote data register (907) is set to 2, ILl” and the free character is far 1’1fii terminal Sent to Buddha 8 times.

The take link processor then registers (90) associated with the port (602). 3) Set a hit in the box to transmit the digital data mote galactor. Also A hit in the DATAPORT register (911) indicates that the port can send and receive serial data. set so that it is possible.

The software counter then takes the far-end terminal to switch to a data mote. Set it to measure the period.

This is because after the register (911) bit is set, the input signal bit is Eventually, it will change to a series of 1s indicating that the far end terminal has switched to data mote VC. Ru.

If a timeout occurs before the far end changes motes, a link failure message is generated. is sent by the data link processor to the Cheetah Bridge processor for connection operation. The work is abandoned.

When a change to a mote is detected, a counter is incremented and indicates a change to a data mote. In order to recognize this, it must be detected that 48 consecutive words are 1. It won't happen. When a change to the take mote is detected, a link success message is displayed. Sent by the Take Link Processor to the Data Fridge Processor.

A disconnect sequence is taken by the take link processor to finish the transfer on the channel. into the room. The sequence is monitored when the channel is controlled [1 mote] Is the channel being set up or is it running on a take meeting call? During this time, instructions from the Cheetah Bridge processor to the Takelink processor Therefore, it is activated.

Does the take link processor receive commands? i then RE　A　D　RE　G Register (910), DATAPORT register (911), and DI Reset the G/ANA register (90'6) and complete - the link will be normal. Notify the data bridge processor of the disconnection.

As mentioned above, eight take link processors are used in the embodiment of the present invention. A port is provided to interface with the ridge processor. day Basic functions of Tallink Processor 11 Commands to Data Fridge Processor So iti! H7 control the configuration of 8 ports and the same All links except period, cyclic retardancy check and human insertion This is to carry out the procedure of Protonil in the 1st novel. Further data link pro The processor sends reports to the data bridge processor when special tasks are performed.

Takelink processor is a system using 8 microprocessors. As shown in Figure 8, read-only memory (808), RAM (829), a programmable interrupt controller (814), a programmable timer (819), and a programmable interrupt controller (814); and other equipment. The take link processor is a bridge processor system. Cheetah Bridge via system bus (609) and interface (802) Interface with the processor. Similarly, port take interface and port Access to the ports is via the take link processor external hash (610).

Medium heat processing equipment (800) Other equipment of ICT data link processor and 8 heat processing equipment via a 16-bit data bus (818) and a 16-bit address bus (817). There are 8 interconnected central processing units.

The data bridge processor (Figures 2 and 10) Issue an address to one of the data link processors on the interface (802) . Once a data link processor is selected, the central processing unit (800) The ridge processor takes the data in the data link processor. Stop controlling 7Tress as much as possible.

The priority interrupt control circuit (814) is a device in the data link processor. Therefore, the interference caused by this and the corresponding port data interface and Several levels of programming for external devices within the eight ports associated with the Allows priority interrupts.

When an interrupt is received by the control unit (8i4), the interrupt request is sent to the processor (8i4). 800) Send +C. The processor (800) checks the quality of the interrupt and Read from memory to execute the first instruction of the routine.

Error source register (81'5)! J processor is the take link processor. Provides a means for identifying externally generated and false errors (by using an IC) do. An internal error is a single parity error such as hash, timeout, RAM failure, etc. Occurs as a result of detection. Po As far as the take processor is concerned, the hardware failure is considered to be an external error. Detected by register (815).

Status register (804) - in the i-data link processor or under its control. Some of the original hardware (used to indicate D state; 1 state register) The bit is connected to the data link (+1 included) or Set 6 to cause 2 Cheetah Bridge processors (, 1 to be set from 2) , This data link processor is also ported to the data link processor as shown in Figure 8. to be able to interface with the port and port cheater interfaces. interface (816). How many address buses (817') The port and port data interface along with the wire 0 data hash (818) Extended through the interface with Ace-J+. Address decoder (80 3) Output selects either port cheater interface or boat.

When a port is selected, the data link processor The port completes its current memory cycle before the port can be used. I have to wait. Then, turn off the boat's A:l control system. data link processor and the data link processor receives the data within a fixed time interval. Allows you to complete Primordial.

Cheetah Ridge Processor (600) ij Cheetah Ridge System Main 1b] ] control processor, shown in FIG. 1-0. In this example, Cheetah free The edge processor is a 16-hit medium heat processor (1000), memory = (100 6), (1007) and (100B), priority interrupt control device (1 012) and other circuits.

Medium heat processing equipment (100) It: J, 2 resident memories, RAM ( 1007) and EPROM (1006) via the resident lotus (1016). to access these memories. Program memory and scratch bat memo For the data flash central processor <1000), the local bus (1 Dynamic RAM (1018) accessible on 017) is used.

Accesses the buffer memory and the memory of the eight data link processors mentioned above. I can. Furthermore, the data link processor on the Hass (609) is a network It can communicate with the physical processor (101).

Peripheral interface control device (1012;) device in U data processor or 8 Prioritized interrupts from external devices such as data link processors Realize. Control unit g (1012) follows a pre-assigned schedule. Automatically resolve priorities between simultaneous interrupts.

The shared buffer memory (603) as shown in Figure 6 is used for port and Temporarily stores data passed between Cheetah Bridge processors [for /C] I can stay.

In an embodiment of the invention, each module has 512 kilohydres of memory 1 It is derived from a 61-hard module with dynamic RAM such as that included in .

Memory is connected to port and boat Cheetah interface via Renka Hasu (611). to the Cheetah Fridge processor system HUS (609). The processor and eight data link processors are capable of . The lotus sequence (604) provides timing and memory refresh for these lotuses. Line 42 - Access allocation.

The frame interval of 125 m5ec is divided into 64 ZAF frames, each of which The kJ data bridge ports are compatible. The valley frame has two more points. one Cheetah Bridge processor access cycle and one Cheetah Bridge processor access cycle. I'm divided. In each port access cycle, the shared buffer memory bus ( 612) is connected to the Buddha lotus <6 t 1) V, and according to the number of time slots 1j1 The selected port reads data from and to the shared buffer memory. The 33 Cheetah fringe processor that drives these hashs refreshes the memory. Other surf frame cycles that use one of eight cycles to refresh During this time, the common buffer memory is accessed.

Regarding the overall operation of the conference device (bow, flow chart from Figure 12 to Figure 20, , The sequence of events that occur when the m1 customer issues a voice/data conference (H) It is best explained by mentioning kens.

The caller of the meeting is a (1500) V in Figure 15, O1700-L 45. 6-1- A 10 or 11 stage conference service such as X 000 Begin by calling your local telephone office to request access. 1st The tigit is used to select the nominal route through the switching equipment, and the switching equipment To automatically identify a customer who is calling for billing. The three tees of θ, 1-1 All customers with a wide geographical area are 1b] for one person. In order to make this possible, we will be providing all the special services that will be provided by the national synopsis. This is a standard coat that can be used to identify services.

In the example used in the description, Tigit 700 is used.

5; The phone call after the seventh event from the stone (for example, ts4561I) Identifies Kogi Zahis, the last four shifts are voice only, voice/data, -request Specify a specific conference service, such as A page (for a conference to be held). For explanation, customer Assume that the user wishes to place an audio/data conference.

Calls are routed through the telephone network in the traditional manner to the toll office system shown in Figure 1. routed to a toll switching system with a network service complex such as Ru.

Switching system (102) selects trunk line of link (131) and starts conference. An initial address message stating that the device is required is sent to the network service on the link (132). to the host complex.

In response to the initial atres network processor (101) ) checks whether there are sufficient conference resources to perform the service. R.A. All available equipment contained within M (1100) 6. and 7 vacancies in use We do this by looking at the table for the states of and . Ten resources for the meeting After checking that the processor (IOI) has received a meeting call, The link (132) exchanges a message requesting the identification of the second line. and sends it to the conversion system (102). The answer tube J-jlj is also sent at this time. returned to the person's station. In the link (131) serving the conference caller The trunk line is then tied to the playback switch in the data store (125). The processor (101) is connected via the slot input fL changing device (124) commands the data store to send a welcome message (N) to the conference caller. do. - The processor (101) also stores the digits sent from the sender (7/). Connect the 'r:r7' receiver (126) to the conference caller's input to receive Relay line: 'ko'l? +, -! ’+, commands the connection Arc.

” Like a double series, the time slot switching device (124) connects the link (131) Performs interconnection between the five internal channels and the time division multiplex data bus (133). Now. Therefore, any channel (i.e. time slot ) received on any link within the same link to make a trunk-to-trunk connection. You can send it to any one person in your mind. Similarly, any time slot on a time-division multiplexed data bus The network information is time-division multiplexed to interconnect the service circuits of the network service complex. It can be sent back via other time slots on the data bus. In this example , to generate a publicity message on the conference screen. The data store (125) is connected to playback l\tfa. Also link (131) The information for any time slot of the via the time slot of the time division multiplexed data store (133) so that it can be connected to and send it. In addition, communications are designed so that more customers can hear public relations messages. The public relations message sent from the playback buffer in the data store (125) is linked ( 131) to selectively transmit via several time slots within Therefore, the time slot changing device (124) can be used for a large number of people. can.

The system related to this invention is a time-sharing system, and the specifications include trunk lines and conference ports. When terms such as session, conference period, channel, and similar terms are used, they actually refer to time sharing. that we are referring to one particular time slot of a multichannel. I want to be understood.

Now, going back to the system operation explanation (C), the processor (101) is connected to the data store ( 125) and the incoming trunk line of the caller, the time slot switching device (124) multiple data buffers associated with the specified playback buffer in the data store. The time slot of the link (133) and the ingress trunk time slot of the link (131) are Command to connect. At the same time, the command sends the serial control bus (134) to the data stream. Wells sent to Tor and directed by orders as shown in box (1501) Enables a cam message to be sent directly to the conference caller.

The welcome message informs the caller that they have been connected to the conferencing service. requesting that you dial the student entry number (SEN) or 1) Ru. Dial tt □ tt like in the box (1502) to call the operator. and then the operator meets the calling customer to set up the requested conference. Performs the same actions as a conference caller. But dial the service entry number. By doing so, the customer indicates that he/she wants to start the meeting under his/her control. vinegar.

A different service entry/number is used to select each feature of the system. I can't think of anything. Example (-31) Customers often follow the steps to start a meeting. If you know it, you may not need to promote input much or at all. . In such cases, the customer will be provided with a brief input prompt, and if the customer is familiar with the directive, If so, interrupt input prompting and print new control information while commands are being replayed. Dial a service entry number that allows you to start dialing.

In this example used for explanation, the service entry number is the one whose service mark (y) comes first. With a 3-day coat like \\Z2671/ or \\+268 II, The latter code indicates that the caller is experienced and only accepts simple input prompts. Assuming 1-ru. If the customer dials the correct service entry , Tigits are collected as shown in boxes (1400) to (1405) in Figure 14. First time. The customer must use his/her phone to dial the service entry number. Using the button, the sound receiver (138) collects digits and controls the and sends it to the NSC processor (101) over the bus (134). sound, ij receiver (13B) is used in telephones to perform timing between digits and digits. Like many well-known digit receivers, Upon receipt, a return to the main flow diagram of Figure 15 occurs, where the customer (box d (150 9) Command to specify the voice port number by dialing as shown in step 9). You will be prompted to dial a number.

The system will ask users to prompt them with appropriate public relations messages. It is designed to. However, (7) the customer responds to the command given by the public relations system and It is also common to make mistakes when dialing the phone. A feature of the present invention is that the system is designed to capture the number of errors made by the 18 conference speakers. subordinate Therefore, if the customer makes a mistake, input prompts are provided to prompt the customer to take the correct action. deer 1 - When a customer makes a series of incorrect measurements, the system automatically sends a switchboard operator to help the customer. For example, as shown in boxes (1504) and (1505), The caller ignored the dial and the system ran out of time. or if a customer dials an incorrect number. In this case, the processor (101) detects the estrus from the box (1200) in FIG. 12 (1206). ) to see if you have made any mistakes before.

If the customer is making too many mistakes, the public relations message should be clear to the operator. When Yusei was about to be called to help someone, he asked the caller to wait. be done.

The network services complex then determines the free T1 trunk of the link (131) and the frost, Point Tsugumi towards the operator's seat (137), and the operator enters the time slot. Connected to the T1 trunk line serving the conference caller via a switching device (12). It will be done.

In this way, the switchboard operator (d) takes control of the call and starts the conference. By controlling the upper voice receiver (138), the operator can set up the conference. (time slot so that commands can be dialed into the network service complex) The tie assigned to the trunk line for which the operator was called via the trunk switching device (127) connected to the muslot. The conference initiator can It must be connected to a frille, and the frille is controlled by the switchboard operator. .

If the threshold of error is crossed, a public relations message will be sent to those in heat. The customer was notified that an error had occurred and then sent a message to the customer to dial C. Input is facilitated. Is this r'' processor (101) the box (1200) in Figure 12? (12013) and sends the appropriate instruction to the data store (125). Jiru.

When the conference caller dials the correct service entry number, the NSC processor The server sends an instruction to the data store (125) to play an input prompt for the caller. Ru.

This prompt asks the caller to dial the number of ports required for the conference.

The digits dialed by the caller are collected by the voice receiver (138) and It is sent to the SC processor (101) and the processor checks whether it is correct. .

At this point in the operation, digit O to 9-1 is the only correct court, and 60 Voice boat t is assigned to one conference. If a star (S) or a number ( If the +) symbol is dialed or the customer does not dial (e.g. timeout), The processor treats this as an error as shown in boxes (1512) and (1513). the caller to take correct action if the threshold has not been exceeded. Promote input. If the threshold is exceeded, the processor (101) -Call the switchboard operator as described above.

The number of voice ports required by the caller is one or more! l'i two digi When dialing the port code, the processor (101) determines that the requested number of ports are available. Inquires about memory (1100) K whether it is available for use. box (as shown in 16001) Once a sufficient number of ports are available, the processor (101) will sends a confirmation message that a sufficient number of voice ports are available to the data store (125). I need to get enough ports For example, the processor (101) plays and sends a publicity message indicating this to the person in heat. The data store (125) is instructed to do so. Estrus ■, it's been a while since I stopped the meeting You can postpone a meeting call in minutes. At this time, the person in heat anticipates the voice port. Dial the number (≠) mark to make a reservation. Processor (101) (/j: Mark the boat in memory as being assigned only to this conference and then navigate to it. Answer the dial marked with a number (÷).

The 16 tones are the number (dial the @ sign 4.z ;j!it: look - then, The processor (101) measures the time of the i'j call and after a certain determined time interval. Box (1607) V with a number (+) stamp or dialed. C shows \l'iΔ-yoC) (Event to attack 11 Kochitabo=i- Sequence of □′One person. The same behavior is the sequence from 0 to 9 for the estrus. Occurs when dialing the tigit, and the tee shifts to T, It';? J+! Sail, Ru.

When the sender dials the star (y), the sender will receive -4 in the box (1604). 'o1, Ujiko 4[] Prompted to enter Kudial J, light (74 people or OIJ) Eye FIT? I want to dial a boat selection code with a lacquer pattern. Just as I was about to hang up the phone, the program sequence loop entered. Turn the star (I) into a diamond Before booking a boat, please check This gives you the opportunity to change your mind and choose a different number of ports.

Meeting estrus number mark (+) K followed by the required total of 14 coats for the number of boats. Assume that you heard it. Upon receiving this, the NSC processor 1-[ A command is sent to the data store (125) to generate one data stream. In this case, public relations The number of data ports to be reserved as shown in the box <1610) "Dial the code shown": Request to the conference caller.

For take meetings, 164 boats per month are used. 00)) The code representing the number of ports is 9, then the processor jlo1)ioI. To check the number of data boats available, check the full number in memory (1000). investigate. If there are enough Cheetah votes, then the processor (101) has J. They are reserved for this meeting, and the professional Seventeenth (701) + is in the box (1705) t. Data store (125) to send the following message to the person in heat: f and sends the command 1'.

If there are enough boats available, there is no need for data boat reservations. The operation sequence is as described above, 3, which is similar to the normal sequence of operations, is performed in FIG. It makes perfect sense F + L, no need to explain further, -5 The next VCN SC processor (101) is As in the first sound-node meeting, the telephone number of the 8 acquaintances was assigned. A public relations message that changes like dialing a number is sent to the person having a seizure. The data store 25) is instructed to do so. In this example used for explanation, audio conference participants are The subscriber's telephone number has the form 1-NPA-NXX-XXXX, with one prefix indicates that this is a participant being added to the bridge, and NPA is a 3-digit location. area court, NXX-XXXX is a 3-digit office court and conference participants' telephones. It is a serial number. In this example, the telephone number assigned to the data terminal takes a special form. with a number stamp (@ followed by the digit 9988). Typical telephone and digital An example of a telephone number assigned to a data terminal is shown in FIG.

Please note that each participant's phone number month is preceded by Tigit 1. . This allows other digits on the phone dial (i.e. Butush key) to The cut can be made as a control signal as described below.

The caller should dial the J:Uni prefix 1 shown in the box (1800), then dial ShisoFL followed by the number 1. 1 audio conference participant's 10 digit code (from box (1810) ('181) 1)). The reputation receiver (138) connects to the instant conference caller. These digits are collected by the audio receiver and processed by the processor. It is sent to server (101). The NSC processor (101) record the number of meetings and associated files in memory for later use. ” and the city via ccr’s termination device (126) and link (132). Sends a service request to the external exchange system (1 (+2). Furthermore, the processor (1 01) U to toll exchange system (Muslot). Called participant's phone number f4! , 1 link (132 ) (box (1812)), and then (7) Ichiyu (exchange system (102) is online) by directing the call over the network to the telephone of the called conference participant in a well-known manner. , answer.

When the participant answers (box (1814)), the relay line used by the accounting 2 caller is tied. connected to the trunk line used to call participants through the slot switching device. Continued. In this mode, the caller can talk to the participants privately. The meeting call is being made, and the participants have joined the 7th meeting. to notify you of such things. At this time, the caller uses his/her own information to add the participant to the bridge. Press the button with the number mark (≠) on the button.

Before adding participants, the processor (101) determines what type of conference to set up. In order to confirm whether the data is correct or not, a pause is placed in that memory (box (1822)). memory If the conference caller (-i audio only, data only, or composite audio) It is possible to wipe the voice/data conference establishment.

At this time, the processor determines whether the audio participant was specified by the caller or not. data participants cannot be added to the data conference or data participants cannot be added to the audio conference. We need to take steps to confirm that this is true.

In the example thus described, the processor (101) recognizes that this is a composite voice/data conference. The NSC processor then asks the caller to join the participant to the appropriate bridge. information on which keys to press to disconnect or permanently disconnect a participant. Prompt and request input of public relations message (Box (2000) in Figure 20) Send the instruction to the data store (125).

In the example described, the caller should send digit 8 when disconnecting the participant. box (2007)), or digit 2 (box) if you want to add a participant to the audio bridge. (2003)) and add the participant to the data bridge. 4 (Box (2006)) is included (,1-,,b).The participant is a voice participant and the caller If the person sends digit 2 as shown in Box (2003), the assumption deviation (・τi , the processor (101) recognizes that the called participant is a user of j'5 no 4 (box ( 2008)), note that participants are not disconnected before being added to the 7ritsi Check with Lee.

In response to digit 2 sent (g) by the conference caller, the processor (1011j : Free prestige boat from memory, which has an indication of the status of all ports. the participants to connect the called trunks on the selected ports to the ifj interconnect. A command is sent to the time slot switching device (124). In addition, the processor (10 1) sends instructions to the control bus (13) to identify the conference and the ports to be added to the conference; 4) to the audio bridge (128).

The NSC processor (101) then instructs the caller to send the next input prompt. command a. This prompt notifies the caller that the participant has been added to the bridge. to dial the next participant or for the caller to join the conference bridge. request the caller to press button 2 to

The conference caller will continue to connect to the remaining participants until all participants are connected to the audio bridge. Continue dialing the number assigned to the person.

The caller dials the phone number associated with the data terminal and uses this terminal as a data bridge. , the caller enters the digit 4 key as shown in the box (2006). Press down. The processor (101)'U confirms that this is a data terminal. Add the data port with the specific bridge (125) I command you to do so. This adds participants to the -1 series of audio bridges (I got stuck). This is achieved in a manner similar to the operation of sends a command to the data bridge instructing it to add a root. -Also processor (1 0'1) is a public relations measure that instructs callers to wait for a response from a data terminal. Instructs the data store (125) to play and send the message. database Exchanging monitoring signals with the called data terminal ('1: may be present), the processor (101) indicates that the port has been added. Report. After that, the processor (101) stores the data end that the data store has finished requesting. Announce to conference callers that the end has been added to the data bridge (Box (2017) ) to the data store (125) on the hash (134) J-.

As discussed above regarding adding both voice phones and data terminals to a conference bridge. The sequence of events is repeated until all participants are added. Outgoing When the caller has the opportunity to join the meeting, the caller presses Butushki's button ts27. 7 Press.

Upon identifying the Tigit VX2 LJ, the processor (101) determines that the caller is Check whether there was a meeting (box (1900)). If not For example, the processor (101) may provide the caller with various information available in the conference service. PR messages that promote options and features of FTJI's human resources. Order data store (125) to play Ji to 6 followers (box (1901)) do. The meeting is already in a stable state, and the voice evening Kagisa (f) data can be exchanged via data devices. The city monitors the lines for various meetings. External exchange system (102) Monitored for disconnection from Vc (box (1907) ). When any participant disconnects, the processor (101) rj-processor A message is received on the link (132) notifying the disconnection. then the processor Started a full meeting time to decide if this was the correct disconnect. Melt. If all silkworms are cut at a certain time interval (Box (1910) and (1913)) The processor (101) is a Cheetah Bridge processor and a voice block processor. Ask the Ridge Processor to disconnect the lines on each bridge for use in other conferences. I order you to cut it off. All participants are not disconnected for a certain time interval and the caller disconnects The teleconference operator then makes a call as shown in box (1912) and number 131N. Served.

In summary, the customer receives only voice and data based on the guidance of publicity messages from the machine. announced conference equipment for establishing hybrid audio/data conferencing.
