摘要： PURPOSE:To synchronize the bit rates between a transmission-side and a reception-side terminals by receiving pattern data at a reception-side adapter, and generating a transmitting and a receiving clocks corresponding to the bit rate of the transmission side by a timing generation part. CONSTITUTION:A pattern data generation part 25 generates pattern data on the bit rate of the transmission-side terminal, a sampling circuit 21 samples the pattern data from a transmission-side adapter, and the timing generation part 22 supplies the clocks for transmission and reception corresponding to the bit rate detected from the output of the circuit 21 to the receiving data terminal. The pattern data is sent out to the transmission-side adapter before data transmission, and this is received by the sampling circuit 21 of the reception side adapter. Then, the generation part 22 generates a transmission and a reception clocks corresponding to the transmission-side bit rate and makes the bit rate of the receiving data terminal coincident with the bit rate of the transmission-side terminal.

摘要： PURPOSE:To execute high speed data transmission accurately, by applying a bit reception clock and a serial-parallel conversion pulse to the reception side from the transmission side. CONSTITUTION:A data in which one frame has 128-channel time slot and each channel consists of 8-bit, is transmitted from a device A to a device B with a highway HW. The data is serial. A bit reception clock BCLK and a serial- parallel conversion pulse CPLS are transmitted with a transmission line provided in parallel with the data highway to the device B. Serial data are stored in a shift register by applying the BCLK to the clock terminal of a serial-parallel converting shift register at reception side. This data is picked up in parallel with the serial-parallel converting pulse CPLS.

摘要： PURPOSE:To facilitate extension and so on, by accessing dial information of the subscriber and so on written into a channel memory to the processing device in the time division electronic exchange where the connection part between the signal processing device and the push-button dial signal receiving device, and so on is simplified. CONSTITUTION:Channel memory SPMT is read out in a prescribed time dependent upon contents of holding memory HM1 and is written into the address assigned to push-button dial receiving unit PBR in channel memory receiver SPMR through highway switch HSW. This data is read into memory HM1 and is input to unit SPMT. When dial information is detected in device PBR, this data SS2 is sent to memory SPMT and is written. When read out, this data SS2 is processed as dial information in device. SPR by access circuit ACS and is reported to the CPU. As a result, extension and so on can be facilitated.

摘要： PURPOSE:To enable the control of system constitution stable, by taking constitution so that the self-contained system constitution and control is made for an arbitrary double system controller, in the system having a plurality of double system controller. CONSTITUTION:The central processing units 21-1 to 22-n constituting a plurality of double system contollers and the fault detection timers FDT 23-1 to 24-n detecting the failure signal provided corresponding to the units 21-1 to 22-n are provided, and the normality of the units 21-1 to 22-n is monitored with the signal of FDT 23-1 to 24-n. The overflow displays 25-1 to 26-n are provided with the units 21-1 to 22-n, which show the signal taken place by FDT 23-1 to 24-n. Further, the automatic selection enable displays 27-1 to 28-n representing that the units 21-1 to 22-n can automatically selected are provided, allowing to determine the units 21-1 to 22-n in advance, which can constitute the system. The logical product between the both displays 25-1 to 26-n and 27-1 to 28-n is taken with the selection control circuit 29 at the occurrence of fault and the output performs selection control.

摘要： PURPOSE:To prevent the deterioration of transmission performance, by exchanging the information of the time slot in the same frame of incoming highway with that in the same frame of outgoing highway, and avoiding the shift in phase even with multiple-frames. CONSTITUTION:The control memory CMa designating the address of communication memory PM performing the write-in and readout of digital signal takes for the capacity for 2 frames' share, and the address information of the memory PM is written in the address corresponding to the time slot equivalent to the first frame of memory CMa and that equivalent to the second frame respectively in the converse order, allowing to give a given frame delay to the time slot. Thus, the information of the time slot in the same frame of the incoming highway HWi is replaced with that in the outgoing high way HWo, and the phase shift is avoided even with the multiframes, allowing to prevent the deterioration of transmission performance.

摘要： PURPOSE:To transmit a signal without distortion by transmitting a sampling rate at the transmission side to a terminal device to be called to make a sampling clock at both terminal devices identical to each other. CONSTITUTION:Plural terminal devices 3, 3' are connected to a private branch of exchange PBX via interface devices IF2, 2'. A timing circuit 22 of a clock pulse of the device IF is preset so that the sampling rate is changed to a prescribed value and a transmission/reception circuit 23 transmits/receives change information of the sampling rate. The circuits 22, 23, a switch 28 and a gate G are controlled by a microprocessor 21. Then the sampling rate of the terminal device of the transmission side is transferred to a terminal device to be called, the sampling clock at both the terminal devices is made identical mutually under the control of the processor 21 to transmit a signal without distortion.

摘要： PURPOSE:To improve the service while keeping the function of an exchange as it is, by storing a number transmitted from a telephone set, and transmitting the number after adding a numeral automatically when an opposite party is busy. CONSTITUTION:In calling a telephone set 1 and selecting a telephone number of a called party, the number is transmitted to an exchange PBX. The number is stored in a storage device 4 in an adaptor. A detecting circuit 5 monitors whether a busy tone is returned from a PBX or a dial tone is returned. When the busy tone is detected, a hooking control circuit 9 is started. As a result, the calling is stopped once and the next calling is attained again. Numeral 1 is added to the number stored in the storage device and the next calling is attained. Thus, other telephone set positioned near the opposite party is called automatically.
摘要翻译：目的：通过存储从电话机发送的号码来保持交换机的功能，同时在对方忙时自动添加数字之后发送号码，来改善业务。规定：在呼叫电话机1并选择被叫方的电话号码时，将号码发送到交换机PBX。该号码存储在适配器中的存储设备4中。检测电路5监视是否从PBX返回忙音，或者返回拨号音。当检测到忙音时，起动控制电路9。结果，呼叫被停止一次，再次进行下一个呼叫。将数字1添加到存储装置中存储的号码中，并进行下一次呼叫。因此，定位在对方附近的其他电话机被自动调用。
