摘要： When an interrupt completion detecting unit detects completion of an interrupt processing, a hooking unit executes hooking automatically. A busy tone detecting unit judges whether or not a station of a suspended telephone communication has been holding the telephone circuit. If not, a call is directed to the suspended station on the basis of stored information on its dialing number. At the same time as the hooking is executed, an on-hook judging unit judges whether or not a handset at the own station is in an on-hook state. If it is on the hook, a predetermined processing for urging an operator to lift the handset is executed. This processing selectively causes ringing of a bell incorporated in a telephone unit or of a buzzer, or indication by a display unit or a lamp. With the above procedure, the telephone communication with the suspended station can automatically be restored in accordance with the situations at the suspended and own stations.

摘要： In a data communication apparatus, when detecting a "catch phone" signal sent out from an exchange, a receiving station requests a transmitting station to resend data by use of protocol information. At the transmitting station, the data resending request is detected in a protocol information analyzing unit, and a predetermined unit of data which was transmitted immediately before the present time is resent. The receiving station has a page deleting unit to save the memory area used to store the data resent and avoid printing of unnecessary data. The page deleting unit enables deletion of data received when a "catch phone" call comes in and permits the resent data to be effectively stored in a memory. Also, in the apparatus, a "catch phone" detecting unit in a transmitting station detects that a circuit connection request comes in from a third station on the basis of a "catch phone" signal sent out from an exchange. A page-end detecting unit detects completion of transmission of a predetermined unit of data. A condition judging unit automatically decides whether to open the circuit or not on the occasion of resending data in accordance with the state of a "catch phone" detecting signal "a" and a page-end detecting signal "b". If the page end is detected in a short time after the detection of a "catch phone" signal, the circuit is not opened. If the "catch phone" signal has continued when the page end is detected, after the circuit is temporarily opened, resending of data is executed.
摘要翻译：在数据通信装置中，当检测到从交换机发出的“抓取电话”信号时，接收站通过使用协议信息请求发送站重新发送数据。在发送站处，在协议信息分析单元中检测数据重发请求，并且在紧接在当前时刻之前发送的预定数据单元重新发送。接收站具有页面删除单元，用于保存用于存储重新发送的数据的存储区域，并避免打印不必要的数据。页面删除单元能够删除当“抓取电话”呼叫进入时接收的数据，并允许将重发数据有效地存储在存储器中。此外，在该装置中，发送站中的“抓取电话”检测单元基于从交换机发出的“抓取电话”信号，检测到来自第三站的电路连接请求。页末端检测单元检测预定数据单位的传输完成。根据“抓取电话”检测信号“a”的状态和页末端检测信号“b”，条件判断单元根据重发数据自动判定是否打开电路。如果在检测到“抓取电话”信号后的短时间内检测到页面结束，则电路不会被打开。如果检测到页面结束时“抓取电话”信号继续，则在电路暂时打开后，执行重新发送数据。

摘要： A facsimile apparatus receives data from a transmitting station and is provided with a capability for determining when an interrupt request signal has been received from another station. It is first judged whether an error has occurred in received image information on one line. If an error occurrence is detected, its time period is then measured. If the error period coincides with the output time period for a prescribed interrupt request signal, it is determined that an interrupt request signal has been received. Further, it may additionally be determined whether the coincidence has occurred a plurality of times in succession thereby affirming the reception of an interruption request signal.

摘要： A data communication apparatus in which if it is determined that a distant station presently in communication is a called station by a distant-station discriminating means, and a call-waiting signal is detected by a call-waiting-signal detecting means, a call-waiting-telephone controlling means is activated. This call-waiting-telephone controlling means switches over the line to the interrupting-station side by controlling a line switching means, and commences processing for an interrupt communication by a call-waiting telephone. Thereby, even if there has been an interrupt request signal, an interrupt communication is not allowed if a distant station presently in communication is in a chargeable state.

摘要： A date communication apparatus in which a message stored in advance is transmitted to a receiving station so as to notify the receiving station that a call-waiting signal has been received, if a call-waiting signal is received by a transmitting station during communication. The reception of a request for line connection from a third station is detected by the call-waiting-signal detecting unit of a transmitting station on the basis of the call-waiting signal transmitted by an exchange. If the call-waiting signal is detected, a preset message is read from a message storage unit, and is transmitted to the other station. This message is transmitted either upon completion of the transmission of all the predetermined data or upon completion of the transmission of data, for instance, in units of pages. By means of this message, it is possible for the operator of the receiving station to identify that the cause of the disconnection of the line and the disturbance of the data is due to the reception of the call-waiting signal.
