摘要： PURPOSE:To obtain a composite exchange executing proper exchange processing in accordance with redundancy by discriminating voice information from data information to form a packet and by interrupting the retrasmission of the voice information having high redundancy even if the fault of transmission is datacted. CONSTITUTION:At the communication between telephone terminals 3, 5, an A/D converter 17 converts a voice signal into a digital signal, then a reception controlling circuit 30 forms a packet by using the discrimination information transmitted by a CPU through a processor 36. The packet is stored in a memory 38 through a direct access memory 37 and then sent to a repeating transmission line 11 through a repeating packet 29. The memory 38 stores the received signal and then the processor 36 confirms the VD information. If the VD information is data information, the information is retransmitted when the fault of transmission is detected, but the voice information is not retrasmitted because of high redundancy even if the fault of transmission is detected, and is transmitted to a voice packet part 14 and then a telephone terminal 5.
摘要翻译：目的：通过将语音信息与数据信息区分开来形成一个数据包，并通过中断高冗余的语音信息的重新发送来获得一个根据冗余执行适当的交换处理的复合交换，即使是发送故障是被通知的。构成：在电话终端3,5之间的通信中，A / D转换器17将语音信号转换为数字信号，接收控制电路30通过使用CPU通过处理器36发送的识别信息来形成分组。分组通过直接访问存储器37存储在存储器38中，然后通过重复分组29被发送到重复传输线11.存储器38存储接收到的信号，然后处理器36确认VD信息。如果VD信息是数据信息，则当检测到传输故障时重发信息，但即使检测到传输故障，也由于高冗余而重新发送语音信息，并被发送到语音分组部分14和然后是电话终端5。

摘要： PURPOSE:To enable automatic receiving of private branch exchange subscribers without the aid of an operator, by providing the function to transfer PBX extension number to PBX in public network and providing the function to receive and analyze this extension number in PBX. CONSTITUTION:A subscriber A dials large private branch number and extension number. Received dial number is analyzed by CC of LS-1, received by an inter station transferring section 8, analyzed by CC of LS-2, and a path to PBX-2 is selected. Out of dial numbers received by LS-2, extension number is transmitted to the signal transmitting and receiving section 10. On receiving the extension number, CC of PBX-2 analyzes this, and calls relevant subscriber B. When the subscriber B replies to the subscriber B is connected to the subscriber's line under receiving. Thus, a communication path is completed between subscribers A and B.

摘要： PURPOSE:To relieve the load of a processing unit by providing a counter counting an error of a reception data, allowing it to discriminate an error of the received data and allowing a device other than the processing unit to process the abolition of the received data in error. CONSTITUTION:A signal transmitted from a data terminal device is demodulated by an MODEM3 and inputted to a line control section 11. When an F pattern is detected during control, the receiving operation is finished. The result of operation of FCS (Frame Check Sequence) is checked at the same time and when it is a specific fixed pattern, it is discriminated as normal reception and when it is a pattern other than the fixed pattern, it is discriminated as a fault reception. The line control section 11 discriminates it as the normal reception as the result of FCS operation, a line error counter 13 is added by (m) at each time and when it is discriminated as fault reception, the line error counter 13 is decreased by (n). When the count value of a line error counter 13 reaches a threshold value or below, the data reception function at a direct memory access control section 12 stops the data reception function.

摘要： PURPOSE:To attain information transmission between terminal equipment different in communication speed by obtaining the maximum communication speed of an opposite side prior to the communication and allowing a terminal equipment having a higher communication speed to adjust the own communication speed so as to be matched to the maximum communication speed of the opposite side. CONSTITUTION:When a terminal equipment 2A dials to call a terminal equipment 2B, an exchange 1A identifies this dial signal and transmits an outgoing terminal number and an incoming terminal number to an exchange 1B via common line signal devices 7A, 7B and a line 7. The exchange 1B calls the exchange 2B from the incoming terminal number and the exchange 2B returns a response signal to the exchange 1A via the line 7. When the identification number of the mutual equipment is informed to the equipment 2A, 2B, the maximum communication speed of the opposite side is discriminated. The equipment having the higher communication speed than the opposite equipment frequency- divides a clock signal and adjusts the own communication speed so as to be matched to the communication speed of the opposite equipment, activates a transmission/reception circuit of the terminal equipment and transmits information via the exchanges 1A, 1B and a line 6.

摘要： PURPOSE:To match the communication speed of a transmission line and a terminal device by frequency-dividing a data fed from the transmission line to transmit the data to a line for terminal device, and also multiplying the data from the line for terminal device to transmit the data to the transmission line. CONSTITUTION:A data from the line for terminal device is stored in a buffer 27. The data is read from the buffer 27 in a clock speed being n-times the data speed of the line for terminal device extracted from the transmission line and transmitted to the transmission line. The data from the transmission line is stored in a buffer 24 and the data is read to the line for terminal device from the buffer 24 in the clock speed being 1/n of the speed of the clock signal extracted from the transmission line.

摘要： PURPOSE:To check surely the normality of a storage device by folding a digital voice signal from a file memory at a line corresponding section to collate the signal with a digital voice signal stored in the file memory. CONSTITUTION:A central controller CC connects the line corresponding section LC of a voice storage device VSE and a subscriber SUB upon request of the subscribe SUB. A line control section LCNT stores a digital voice signal to a magnetic disc device DKU. When the contents of storage are read from the device DKU, the control section LCNT generates a frame pulse and a pulse representing voice/no voice and transmits the pulse to the corresponding section LC. The control section LCNT stores a folded signal to the device DKU. The central controller CC collates a voice signal read from the device DKU with the folded signal.
