摘要： PURPOSE:To relieve the quantity of load of the maintenance personnel by automating the link setting job with all exchange nodes under the control of a sub service control node at the extension of a sub service control node. CONSTITUTION:A notice means of a number of exchange nodes 110 under the control of a sub service control node 105 relating to itself is provided in a main service control node 101 and a communication means with the main service control node 101 is provided in the sub service control nodes 105. Then the processing setting a link to all the exchange nodes under the control is executed by allowing the extended service control node to inquiry about a list of the exchange node numbers under the control to the main service control node at the extension of the sub service control node. Thus, a job for exchange nodes under the control to set a link is not required.

摘要： PURPOSE:To efficiently attain a specified processing in spite of the number of total peripheral equipments by temporarily transferring identification information of the specified peripheral equipment from a controller-side to the peripheral equipment, adding identification information at the time of transferring information from the peripheral equipment to the controller-side so as to return information. CONSTITUTION:A controller 1 is connected with the peripheral equipments 2 through an interface 3. The controller 1 transmits control information having an information field to which a value showing that it is the specified equipment is set to the specified peripheral equipment executing the specified processing. The specified peripheral equipment edits notice information including the information field and transmits it to the controller 1-side. Since the value that it is the specified equipment is set in the information field of the controller 1 at the time of receiving notice information, it can judge whether the specified processing is to be executed or not. Thus, a processing for referring to whether it is the specified peripheral equipment executing the specified processing or not is executed in the peripheral equipment 2 and a load by the specified processing of the controller 1 is reduced.

摘要： PURPOSE:To repeat a multiple call not necessitating TSSI guarantee by a switching network against TSSI guarantee by adding the indication of the necessity/non-necessity of the TSSI guarentee to the call setting information of a subscriber, and connecting the multiple call to the switching network against the TSSI guarantee if the TSSI guarantee is not necessitated. CONSTITUTION:When a call originating subscriber 1 executes the multiple call connection for a call terminating subscriber 6, as for the call setting information sent from the subscriber at the time of call origination, TSSI guarantee necessity indication is set to transmission capacity in an information element in the case of a TSSI(Time Slot Sequence Integrity) guaranteed call, and TSSI guarantee non-necessity indication is set to the transmission capacity in the information element in the case of a TSSI non-guaranteed call. A subscriber exchange 2 analyzes the received cell setting information, and selects a transit switch and switching network to connect. Thus, in the case of the TSSI non- guaranteed call, it can be repeated by selecting the transit switch the switching network against the TSSI guarantee.

摘要： PURPOSE:To improve line utilizing efficiency by storing transmission information to each terminal equipment and applying transmission and reception from a transmission destination without interrupting a line on the condition that the transmission information for its own equipment exists in the terminal equipment of the transmission destination. CONSTITUTION:A terminal equipment T21 finishing the reception of picture and writing information 10 sends a protocol signal MCF' to a terminal equipment T20 when transmission picture and writing information addressed to the terminal equipment T20 is stored in its own equipment. The terminal equipment T20 receiving the protocol sends a protocol signal DCN' to the terminal equipment T21. The protocol signal DCN' represents the enabled transmission from the terminal equipment T20 to the terminal equipment T21 and constituted with a signal code different from a protocol signal DCN or a specific frequency signal. Thus, the document information stored in its own equipment is sent from the terminal equipment T21 as the picture and writing information 1 to the terminal equipment T20. Thus, the information is sent bidirectionally by one line connection control.

摘要： PURPOSE:To prevent a pushbutton signal tone from being listened to other subscribers by detecting the pushbutton transmitted from a subscriber for a service request during conference talking and eliminating immediately. CONSTITUTION:When a meeting halfway withdrawal request is generated from a telephone set 1 of a subscriber during conference talking, the pushbutton signal is digitized and multiplexed. Then a multi-frequency signal reception circuit 3 detects the signal, applies interruption to a microprocessor 6, and the button signal is outputted to a selector 7 to inform a time slot number corresponding to the telephone set 1 from which the button signal is outputted. Since the multi-frequency signal reception circuit 4 receives and informs the button signal, the processor 6 receives and stores the button signal and analyzes the content to decide the performance of the meeting halfway withdrawal service. On the other hand, the selector 7 transmits a silence pattern '0' to a time slot informed from the multi-frequecncy signal reception circuit 4. No button signal representing the meeting halfway withdrawal service is outputted to an adder circuit 5.
摘要翻译：目的：通过在会议通话期间检测从用户发送的用于服务请求的按钮，立即消除按钮信号音，以阻止其他用户收听按钮。构成：在会议通话期间，当从用户的电话机1产生会议中途提款请求时，按钮信号被数字化和多路复用。然后，多频信号接收电路3检测信号，对微处理器6施加中断，按钮信号输出到选择器7，通知与输出按钮信号的电话机1对应的时隙号。由于多频信号接收电路4接收并通知按钮信号，处理器6接收并存储按钮信号并分析内容以决定会议中途提款服务的性能。另一方面，选择器7将静音图案“0”发送到从多频信号接收电路4通知的时隙。代表会议中途提取服务的按钮信号被输出到加法器电路5。

摘要： PURPOSE:To test a series of operations as the system automatically at all times, by starting a test attendant board periodically at a test incoming line trunk, and monitoring it at a check circuit. CONSTITUTION:In closing a key AR, a clock circuit 7 counts time in self-control, and a relay ST in a check circuit 6 is turned on and off. While the relay ST is activated, a test incoming line trunk 4 is grounded and a relay A is operated, a control circuit 8 illuminates the incoming lamp of a test attendant board 5 and monitors the response. Further, the check circuit 6 transmits ground to the control circuit 8 via a contact st through the operation of a relay P. When this earth signal connects the trunk 4 and the board 5 with the response of the control circuit 8 to activate a relay T. Since the relay P is restored with the operation of the relay T, an alarm relay AL is not operated, thus the normality is confirmed.

摘要： PURPOSE:To automatically call a called subscriber when his line becomes free and to connect calling subscribers which are in a waiting state in the order of arrival for talking, by sending out a talkie voice to the calling subscribers by talkie connection and registering said voice in a waiting cue, in the case that the subscriber line is busy when the called subscriber is called from a telephone office. CONSTITUTION:When subscribers C and D call a subscriber B while the subscriber B is talking with a subscriber A under the talking condition (i), a waiting call condition (j) is set and the subscribers C and D are informed that the line is busy with a talkie voice, ''the line is busy, please hold the line'', etc. When the switchboard detects that the talking between the subscribers B and A is over, the ringing tone is sent to the subscriber B, the first calling subscriber C is called, and the talkie voice is continuously sent to the other calling subscriber D under the calling condition (k). When the switchboard detects that the called subscriber B takes up his receiver, the switchboard closes the channel and connects the waiting subscriber C with the called subscriber B under the talking condition (l).
