The central processing unit 8 stores in FIG. 4 in the storage unit 7 in order to manage the connection status of the telephone terminal of each extension port in the apparatus.
Create a connection status management table as shown in FIG. For example, in FIG. 323
When the telephone 6 is connected to the extension port P of the same extension port number N, the central processing unit 8 turns on the connection status of the exchange device dedicated telephone connection status area of the extension port number N in the table (for example, “1”). )). H. The connection status in the H.323 telephone connection status area is set to ON (for example, “1”), and the IP address of the telephone is registered in the IP address area. If the exchange-specific telephone 5 is not connected, the connection status in the exchange-specific telephone connection status area is changed to OF.
F (for example, “0”). If the H.323 telephone 6 is not connected, H.323 The connection status in the H.323 telephone connection status area is set to OFF (for example, “0”). H. Three
If the connection status of the 23 telephone connection status area is OFF, the subsequent IP address has no meaning. In addition, the user of the telephone terminal connected to the extension port number N receives the switching device dedicated telephone 5 or the H.264 terminal. If a setting is made using the H.323 telephone 6 to store the message of the other party in the storage unit 7 without receiving a call even if there is an incoming call from the other party (message setting), the extension port number in the connection status management table of FIG. The central processing unit 8 turns ON the message setting ON / OFF area of each of the N telephone terminals.

First, the operation when the other party makes a call through the public telephone line 100 will be described.

When a call is received from the general public line 100 to the internal telephone, first, the call control processing unit 13 recognizes an incoming call through the line interface unit 14 in the general public line interface unit 1. Then, the incoming telephone number is notified to the central processing unit 8 through the internal bus 10. The central processing unit 8 uses the telephone number information to determine which extension port in the apparatus the telephone number corresponds to.
The connection status of the telephone dedicated to the exchange of the extension port is searched.

As a result of the above search, a telephone dedicated to the exchange is connected to the extension port and the message setting area is set to O.
The operation in the case of the FF will be described below.

The central processing unit 8 outputs a switching control signal indicating to which channel in which data stream the call control signal from the general public line 100 is assigned to the general public line interface unit 1 through the internal bus 10. In the general public line interface unit 1, the codec unit 12 encodes an incoming signal. Then, the coded incoming signal is input to So5 of the switch unit 11. The switch unit 11 assigns an appropriate data stream and channel based on the switching control signal sent from the central processing unit 8. In the case of FIG. 3, the coded incoming signal is switched from So5 to Si1 of the switch unit 11 after a certain period of time, and assigned to the channel corresponding to the destination telephone number. For example, TDM bus 9
An incoming signal is assigned to the data stream number Dsi1 and channel 0.

The switch interface section 41 in the switching apparatus dedicated terminal accommodating section 4 takes in a data signal from the TDM bus 9 and outputs data of the terminal telephone to the TDM bus 9. Therefore, the incoming signal assigned to Dsi1 and channel 0 is fetched, and the signal is decoded by the codec unit 42. The incoming signal decoded by the codec section 42 is output to the switching device dedicated telephone 5 through the terminal interface section 43, and the telephone bell corresponding to the destination telephone number rings. When the user picks up the telephone and the handset of the exchange-dedicated telephone is off-hook, the off-hook signal is encoded by the codec section 42 through the terminal interface section 43 in the exchange-dedicated terminal accommodating section 4 and transmitted through the switch interface section 41. , Dso1 of the TDM bus 9, and channel 0. The switch unit 11 in the general public line interface unit 1 fetches the coded off-hook signal of the terminal telephone in the apparatus assigned to Dso1 and channel 0, and switches from So1 to Si5. Then, the data is decoded in the codec section 12, and the line interface section 14
, The off-hook signal of the telephone in the device is transmitted to the other party who made the call.

A telephone call is established by such a series of operations. After that, an actual conversation takes place, but the form of operation is the same as before, and the only difference is the path through which the audio data flows. For example, voice data from the other party is encoded by the codec unit 12 in the general public line interface unit 1, switched from So4 to Si0 by the switch unit 11, and assigned to Dsi0 and channel 0 of the TDM bus 9. The switch interface section 41 in the switching apparatus dedicated terminal accommodating section 4 takes in the data, decodes the voice data in the codec section 42, and transmits the voice of the other party to the switching apparatus dedicated telephone 5. On the other hand, the voice data of the switching apparatus dedicated telephone 5 is encoded by the codec section 42 through the terminal interface section 43 in the switching apparatus dedicated terminal accommodating section 4.
1 is assigned to Dso0 of TDM bus 9 and channel 0. This voice data is captured by the switch unit 11 in the general public line interface unit 1 and is switched from So0 to Si4 of the switch unit 11. Then, the voice data is decoded by the codec unit 12, and the telephone set 5
To the other party. When the conversation is over, the telephones are hooked on each other, and the operation at that time is the same as the case of the above-mentioned incoming call signal, and will not be described.

Next, the central processing unit 8 searches for the connection status of the exchange-specific telephone 5 of the extension port in the storage unit 7,
When the telephone 5 for exclusive use of the exchange device is not connected, 323
Only the telephone 6 is connected and the message setting area is OFF
A description will be given of a case where it is detected that

The central processing unit 8 stores the H.264 of the extension port P in question. The connection status of the H.323 telephone 6 is searched. H. 323
When the telephone 6 is connected to the extension port P,
The central processing unit 8 sends the IP address to the LAN interface unit 2 via the internal bus 10. Further, a switching control signal is output to the general public line interface unit 1 through the internal bus 10 so as to be assigned to a data stream and a channel number corresponding to the corresponding IP address. In the general public line interface unit 1, the codec unit 12 encodes an incoming signal. The encoded incoming signal is input to So5 of the switch unit 11, and the switch unit 11 assigns an appropriate data stream and channel based on the switching control signal sent from the central processing unit 8. In the case of FIG. 3, the coded incoming signal is output from the switch unit 11 after a certain period of time.
5 is switched to Si3 and assigned to the channel corresponding to the corresponding IP address. For example, an incoming signal is assigned to the data stream number Dsi3 and channel 0 of the TDM bus 9. The switch interface unit 21 in the LAN interface unit 2 captures this signal, encodes the signal by the codec unit 22, and adds the corresponding IP address, MAC address, and the like to the data by the packet interface unit 23 to generate an Ethernet frame. . This Ethernet frame is transmitted by the H.264 connected to the corresponding extension port P. The frame 323 is received by the H.323 telephone 6 via the terminal interface unit 24, and a frame error is checked. LAN interface 2
Is H. An exchange is performed with the H.323 telephone set 6 in order to determine an audio compression scheme in a pseudo manner. Then, H. At the H.323 telephone 6, a bell indicating an incoming call is generated. When the telephone 6 goes off-hook, the off-hook signal is LA
The codec section 22 through the terminal interface section 24 and the packet interface section 23 of the N interface section 2
, Is encoded by the codec unit 22, and is assigned to an appropriate data stream and channel by the switch interface unit 21. And Ds of the TDM bus 9
o3, assigned to channel 0. The switch unit 11 in the general public line interface unit 1 is the H.0 assigned to Dso3 and channel 0. 323 telephone 6 is coded, and So3 to Si5
Switch to Then, the data is decoded in the codec section 12 and transmitted through the line interface section 14 to the internal H.264 device. The off-hook signal of the H.323 telephone 6 is transmitted to the other party who made the call.

In this way, the caller through the general public line 100 and the H.264 in the apparatus are connected. 323 telephone 6
A communication call is established between the device and. After that, an actual conversation takes place, but the form of operation is the same as before, and the only difference is the path through which the audio data flows. For example, voice data from the other party is encoded by the codec unit 12 in the general public line interface unit 1,
The switch unit 11 switches from So4 to Si2.
Dsi2 of DM bus 9 is assigned to channel 0. The switch interface unit 21 in the LAN interface unit 2 fetches this data, and
2, the packet interface unit 23 adds a synchronization signal, a header, and an FCS termination code to the encoded data to generate an Ethernet frame. Notify 323 telephone 6. On the other hand, H. 32
3 The voice data of the telephone 6 is transmitted to the LAN interface 2
Is encoded by the codec unit 22 through the terminal interface unit 24 and the packet interface unit 23, and is assigned to Dso2 and channel 0 of the TDM bus 9 through the switch interface unit 21. This voice data is fetched by the switch unit 11 in the general public line interface unit 1,
Switched to i4. Then, the voice data is decoded by the codec unit 12, and the voice data of the telephone dedicated to the switching device 5 is transmitted to the other party through the line interface unit 14. When the conversation is over, the telephones are hooked on each other. The operation at that time is the same as the case of the above-mentioned incoming call signal, and will not be described.

Next, communication with the terminal telephone in the apparatus when the other party makes a call through the Internet 200 will be described.

When the other party makes a call through the Internet 200, an Ethernet frame as shown in FIG. 5 is input to the packet interface unit 23 through the Internet interface unit 3. When an Ethernet frame is input to the packet interface unit 23 of the LAN interface unit 2, the H.264 having the corresponding IP address is transmitted. The H.323 telephone 6 performs a frame check, and if there is an error in the frame, the frame is discarded. When there is an error, the error is notified to the other party through the Internet interface unit 3 and the same data is transmitted again. However, this is only a call control signal such as an incoming call, outgoing call, or disconnection. The reason is that if an error occurs in the Ethernet frame containing the call control signal in the data, a problem such as the inability to establish or disconnect the call forever will occur. Immediateness is required for voice data, and even if a data error occurs in a frame, a request to transmit the data again is not output. Then, an agreement with the partner on the audio compression method and the like is made. The LAN interface unit 2 recognizes the destination IP address in the IP header part of the Ethernet frame, and notifies the central processing unit 8 of the destination IP address via the internal bus 10. The central processing unit 8 searches the storage unit 7 for which extension port in the apparatus the IP address corresponds to. The connection status of the H.323 telephone 6 is searched. As a result of the search, H.P. When the H.323 telephone 6 is connected and the message setting is not performed, the Ethernet frame is set to the corresponding H.323. 32
(3) The telephone is fetched by the telephone 6, and a bell indicating an incoming call rings. H.
When the H.323 telephone 6 goes off-hook, the off-hook signal is sent to the other party through the LAN interface unit 2 and the Internet interface unit 3 to establish a call with the other party. Voice communication is performed similarly.

Here, as a result of the central processing unit 8 searching the storage unit 7, H.264 is assigned to the corresponding extension port. The case where the H.323 telephone 6 is not connected, the telephone for exclusive use of the switching device 5 is connected, and no message setting is performed (the message setting area is OFF) will be described.

The central processing unit 8 sends H.264 to the corresponding extension port.
If the H.323 telephone 6 is not connected, the connection status of the telephone dedicated to the switching device is searched. If the connection has been found, the central processing unit 8 sends the call control signal and the voice signal extracted from the Ethernet frame to the LAN interface unit 2 so that the call control signal and the voice signal are appropriately loaded on the TDM bus 9. A switching control signal is output to the section 1 through the internal bus 10 so as to be assigned to a data stream and a channel number corresponding to the telephone for exclusive use of the switching device.

The Ethernet frame including the incoming signal input to the LAN interface unit 2 is encoded by the codec unit 22 through the packet interface unit 23.
Through the switch interface unit 21, for example, TDM
Dso3 of bus 9 is assigned to channel 0. Since this incoming signal has to be connected to the switching apparatus dedicated telephone set 5, the switch section 11 in the general public line interface section 1 fetches the coded incoming signal of Dso3 and channel 0, and from the So3 in the switch section 11. S
i1 and after a certain period of time
1. Assign to channel 0. The subsequent operation and the data path are the same as the operation when the other party calls the exchange-dedicated telephone 5 through the general public line 100, and the incoming signal is assigned to Dsi1 of the TDM bus 9, channel 0. This signal is taken into the switching device dedicated terminal accommodating section 4 and the corresponding switching device dedicated telephone 5
And the bell will ring.

The off-hook of the switching apparatus-dedicated telephone 5 with the bell ringing is the same as the operation when the other party makes a call to the above-mentioned terminal telephone through the general public line 100, and Dso1 of the TDM bus 9 , Channel 0. General public line interface 1
The switch unit 11 in the inside takes this signal, switches from So1 to Si3, and assigns it to Dsi3 and channel 0 of the TDM bus 9 after a certain period of time. And LA
Switch interface unit 2 in N interface unit 2
1 takes out this signal and encodes it by the codec unit 22 using the encoding method first agreed with the other party. The encoded data is added to the other party's IP address, own IP address, and other data by the packet interface unit 23 to be converted into an Ethernet frame, and an off-hook signal is transmitted to the other party through the Internet interface unit 3.

A call for communication with the other party is established by such a series of operations. This is where the actual conversation begins. The mode of operation is the same, and the difference lies in the data communication path. The audio data from the other party passes through the Internet interface unit 3, is expanded by the codec unit 22 in the LAN interface unit 2, and is encoded so that it can be assigned to the TDM bus 9. This data is assigned to Dso2 and channel 0 of the TDM bus 9 by the switch interface unit 21. This data is switched from So2 to Si0 by the switch section 11 of the general public line interface section 1. The switch interface section 41 in the switching apparatus dedicated terminal accommodating section 4 fetches the data, and the codec section 42 decodes the audio data. Then, the voice of the other party is transmitted to the telephone 5 for exclusive use of the switching device. On the other hand, the voice data of the telephone dedicated to the exchange 5 is transmitted to the codec 42 via the terminal interface 43 in the terminal accommodating unit 4 for the exchange.
It is encoded so that it can be assigned to the DM bus 9, and the Dso of the TDM bus 9 is
0, assigned to channel 0. This voice data is transmitted to the switch unit 1 in the general public line interface unit 1.
1, and is switched from So0 to Si2 of the switch unit 11. Then, the voice data is encoded by the codec unit 22 in the LAN interface unit 2 by the encoding method decided with the other party, and the packet interface unit 23
Then, the voice data of the telephone set 5 for exclusive use of the exchange device is transmitted to the other party through the Internet interface unit 3. When the conversation is over, the telephones are hooked on each other. The operation at that time is the same as the case of the above-mentioned incoming call signal, and will not be described.

Next, a case where a message is set from each extension port will be described. This can be done, for example, by switching device-specific telephone 5 or H.264. This is a case where the user of the H.323 telephone 6 is absent.

When a call is received from the general public telephone line 100, it is necessary to first establish a call in order to store a message. Therefore, the central processing unit 8 outputs a signal having the same function as the off-hook of the terminal telephone. Output to the general public line interface unit 1 through the bus 10. The data is
The signal is decoded by the codec unit 12 of the general public line interface unit 1 and output to the general public line 100 through the line interface unit 14, an off-hook signal is transmitted to the other party, and a call with the other party's telephone is established. If the user of the terminal telephone is not present, the message of the other party must be stored. Therefore, the central processing unit 8 extracts the message data to that effect from the storage unit 7 and outputs it to the general public line interface unit 1. . The data is decoded by the codec unit 12 of the general public line interface unit 1,
Through the line interface unit 14, the general public line 10
0 is output and the message is transmitted to the other party. The other party listens to the message and tells the message,
The data is encoded by the codec unit 12 through the line interface unit 14 in the general public line interface unit 1 and stored in the storage unit 7 through the internal bus 10. Central processing unit 8
Transmits a signal to the terminal telephone used by the user to indicate to the user that the message is present in the storage unit 7. Telephone for exclusive use of exchange device 5; 323 telephone 6
In the above, the display unit composed of an LED or the like is turned on to notify the user.

Voice via Internet 200
When a call is received by over IP, the central processing unit 8 also needs to first establish a call. Three
23, a signal having the same function as the off-hook of the telephone set 6 is sent to the LAN interface unit 2 through the internal bus 10, and the data is packetized by the packet interface unit 23 in the LAN interface unit 2 and transmitted to the other party through the Internet interface unit 3. Sent.

In this way, a call with the other party is established. Then, the central processing unit 8 retrieves the same message data from the storage unit 7 and sends
To the LAN interface 2
The codec section 22 encodes the message data, the packet interface section 23 packetizes the data, and assembles a frame. Then, the message is transmitted to the other party through the Internet interface unit 3. The other party hears the message and delivers the message.
The message data is extracted from the packet by the packet interface unit 23 in the LAN interface unit 2 through the Internet interface unit 3, decompressed by the codec unit 22, and stored in the storage unit 7 through the internal bus 10. To memorize. Similarly to the above, the central processing unit 8 transmits a signal to the terminal telephone used by the user to indicate to the user that the message is present in the storage unit 7. Exchange device dedicated telephone 5,
H. On the H.323 telephone 6, a display unit made up of an LED or the like is turned on to notify the user.

When the message data is stored in the storage unit 7,
It is stored in a format as shown in FIG. Each area is composed of a header area and a message data area. In the header area, a source telephone number or a source IP address and a destination telephone number or a destination IP address are described. In the message data area, voice data of the message is written. When the communication method of the destination telephone terminal is different from the communication method of the transmission source, for example, when the transmission source makes a call through a general public line, the switching device dedicated telephone 5 is not connected to the destination,
H. When the H.323 telephone 6 is connected, the destination telephone number is converted into a destination IP address and stored in the header area. Now, when an operation to listen to a message is performed from the exchange-specific telephone 5 connected to the extension port N, the central processing unit 8 searches the storage unit 7 and the same telephone number as the telephone number of the extension port N is stored in the header. It is determined whether or not it is not in the telephone number of the destination of the area, and if it exists, the voice data, which is the content of the message, is transferred to the switching device dedicated terminal accommodating unit 4. Then, through the codec section 42 and the terminal interface section 43, the voice data is reproduced from the telephone dedicated to the switching device 5. H. When an operation to listen to a message message is performed from the H.323 telephone 6, the central processing unit 8 stores in the storage unit 7
To determine whether or not the same IP address as the IP address of the extension port N exists in the destination IP address in the header area. If the IP address exists, the voice data as the message content is transmitted to the LAN interface unit 2. Transfer to The voice data is transmitted through the H.264 through the codec unit 22, the packet interface unit 23, and the terminal interface unit 24. 32
