摘要： PURPOSE:To obtain a reverse signal transmitting circuit with which the generation of noises is reduced by combining a relay having a set of transfer contacts and a contact protecting circuit consisting of capacitors and resistances. CONSTITUTION:A relay RBa is actuated by a driving circuit DV when a reverse signal is produced and therefore transfer contacts rba0 and rba1 are actuated together with a make contact rba2 respectively. At the same time, a relay RBb is also actuated in response to the actuation of the relay RBa. Thus a series circuit of resistances R1 and R2 and capacitors C1 and C2 is connected to the transfer contacts rbb0 and rbb1 respectively. As a result, the DC power supply voltage -48V is impressed to a chip terminal T via a DC superposition circuit DC and the contact rba1. Then a ring terminal R is grounded via the contact rba0 and the circuit DC, and a reverse signal is transmitted. Thus it is possible to obtain a reverse signal transmitting circuit with which the generation of noises is reduced.

摘要： PURPOSE:To attain exchange of asynchronous data with less error by applying exchange processing to the asynchronous data by means of the sampling system to correct sampling distortion produced because of low sampling frequency. CONSTITUTION:When a time of a flag F is short, a prescribed value or below because of detection of changing point of (1), (0) of data bits D0, D1, a phase supervisory control circuit PHC gives a +DELTA control signal CS to a clock control circuit CLC to control the phase of a high speed clock HSC thereby making the period of the load clock LC to T+DELTA. That is, since the time width of the flag F shows a phase difference between the changing point of de-sampling data and the load clock LC, the phase of the load clock LC is controlled so that the phase difference is within a prescribed range, the de-sampling data having sampling distortion is corrected and the result is fed to a terminal device DTEB. Thus, economical exchange processing of asynchronous data is attained.

摘要： PURPOSE:To prevent distortions from increasing in a system which exchanges and connects data terminals through an MODEM pool, by installing a means which disassembles and assembles characters to the MODEM pool and by once performing the discrimination of each character. CONSTITUTION:Since a converting device CHA which disassembles and assembles characters is connected to an MODEM pool MDP, character discrimination of a digital signal received from a digital line circuit DLC is performed at the converting circuit CHA and the discriminated character is transferred to a converting section DC after it is converted into digital data. Moreover, the converting device CHA also makes character discrimination on digital signals from the converting section DC and transfers the discriminated character to the digital line circuit DLC after converting it into digital data. Therefore, addition of sampling distortion and analog conversion distortion expected when data terminals are connected through the MODEM pool MDP is eliminated and the summed distortion becomes smaller.
摘要翻译：目的：为了防止在通过MODEM池交换和连接数据终端的系统中发生变形，通过安装一个拆卸和组合字符到MODEM池的方法，以及一旦执行每个字符的区分。构成：由于将字符组合并组合的转换装置CHA连接到MODEM池MDP，所以在转换电路CHA处执行从数字线路电路DLC接收的数字信号的字符识别，并且将识别的字符传送到转换部分 DC转换成数字数据后。此外，转换装置CHA还对来自转换部分DC的数字信号进行字符识别，并将其识别的字符转换成数字数据后将其转换为数字线路电路DLC。因此，消除了通过MODEM池MDP连接数据终端时预期的采样失真和模拟转换失真的增加，并且求和的失真变小。

摘要： PURPOSE:To prevent an unqualified party from being permitted to dial illegally by devising the telephone set so that a call from the telephone set is not allowed so long as a same voice print as that of a qualified party is not inputted. CONSTITUTION:A voice print registration means 100 executes a predetermined registration and a voice print of the voice inputted from a transmitter is registered. A voice print registration means 200 collates the voice print of the inputted voice from a transmitter with the voice print registered in the voice print registration means 100 when prescribed dialing is executed and the dialing is allowed only when both the voice prints are coincident. Thus, so long as the same voice print as that of a qualified party is not inputted, the dialing from the telephone set is not allowed. Thus, the possibility of permitting illegal dialing by an unqualified party is precluded.

摘要： PURPOSE:To make a telephone set system inexpensive by providing a call con trol processing part and a modularized packet control processing part for a line interface, executing distributed control for call control and packet control with these processing parts, and removing the packet control processing part when the packet control is unnecessary. CONSTITUTION:A line terminal module 10 straddles call control information (S information) and packet control information (P information). A call control processing part 24 analyzes the message of the call control information and executes the communication with a main control part 18 (the control of the path of an extension, etc.,). A packet control processing part 26 executes packet processing for the packet control information and the communication with the main control part. Further, the main control part 18 controls a network 14, an extension terminal, etc. Thus, the packet control processing part 26 can be unnecessary to be provided for a telephone set system which does not need the packet control, and the inexpensive system can be obtained by provid ing the call control processing part 24 and the packet control processing part 26 for the system and executing the call control and the packet control in separate processing parts (processors).
