摘要： PROBLEM TO BE SOLVED: To provide a high-speed and compact QoS circuit, especially a WFQ circuit for performing queue control. SOLUTION: The WFQ circuit 100 using a weighted round robin has a storage means for storing the values of quotient counters corresponding to each of a plurality of input ports and the value of a remainder counter. The WFQ circuit 100 selects the quotient counter of the minimum value in the quotient counters, transmits a transmission request from an input port corresponding to the selected quotient counter to a later-stage circuit, and updates the values of the quotient counters except the selected one to values obtained by subtracting the values of the selected quotient counter from them. A value obtained by adding the frame length of input from the input port corresponding to the selected quotient counter to the value of the remainder counter corresponding to the input port is divided by the value of a prescribed weight corresponding to the input port. The value of the selected quotient counter is updated by the quotient of a divided result. The value of the remainder counter corresponding to the input port is updated by the remainder.

摘要： PROBLEM TO BE SOLVED: To perform traffic shaping for controlling a token rate precisely. SOLUTION: By a traffic shaping method, packet transmission is controlled based on a token counter value added by a predetermined period with the token size as an upper limit. When a sum value is added to the token counter value, the token counter value is compared with a value obtained by shifting the token size to the left by a prescribed shift value. When the token counter value is larger than the value obtained by shifting the token size to the left by the shift value, the token size is stored in a token counter storage section as the token counter value. When the transmission request of a packet is received, the transmission of the packet is requested based on the token counter value. When the transmission of the packet is requested, a value obtained by shifting the frame size value of the packet to the left by a shift value is subtracted from the token counter value.

摘要翻译：要解决的问题：进行精确控制令牌速率的流量整形。解决方案：通过流量整形方法，基于以令牌大小为上限的预定周期添加的令牌计数器值来控制分组传输。当向令牌计数器值添加和值时，将令牌计数器值与通过将令牌大小向左移动规定的移位值而获得的值进行比较。当令牌计数器值大于通过将令牌大小向左移位移位值而获得的值时，令牌大小作为令牌计数器值存储在令牌计数器存储部分中。当接收到分组的传输请求时，基于令牌计数器值来请求分组的传输。当请求发送分组时，从令牌计数器值中减去通过将分组的帧大小值向左移位移位值而获得的值。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a key telephone system capable of reducing a call loss rate caused by the mismatch of codec between a transmitter side and a receiver side. SOLUTION: In the key telephone system housing one or more telephone sets, when a telephone set housed in the system returns an incoming call rejection signal for an incoming call to a caller, contents of the incoming call rejection signal are analyzed, and if the telephone set can convert the codec resulting in incoming call rejection because of the mismatch of the codec into the other codec capable of receiving the incoming call, the incoming call rejection signal is not returned to the caller side but the telephone set is re-called using a codec capable of receiving an incoming call from this telephone set, and codec conversion is executed for the subsequent communication of the telephone set which responds to the re-calling. When a telephone set in the own key telephone system transmits a signal, an identifier indicating the kind of codec convertible by the own telephone system is added to a transmission signal in addition to the kind of codec installed in the telephone set and the signal is transmitted, and when a response to the transmission shows the codec not installed in the telephone set, codec conversion is executed for subsequent communication.

摘要： PROBLEM TO BE SOLVED: To prevent erroneous transmission of FAX and to support smooth input of a FAX number. SOLUTION: Each time a push-button of an operating unit 11 is pressed, a numeral number corresponding to the push-button is sent to a collation unit 21, and the collation unit 21 collates an inputted number sequence with a transmission enabled list. In the case that a FAX number forwardly matched with the inputted number sequence can not be detected, a user is warned about absence of the transmission enabled FAX number corresponding to the inputted number sequence. Thus, the user can notice an error prior to inputting all the destination FAX number. Furthermore, in the case that the number of FAX numbers forwardly matched with the inputted number sequence is a little, a FAX machine 1 is notified of all the forwardly matched FAX numbers, and the FAX machine 1 causes the user to select any FAX number. Thus, the user can easily designate a destination of FAX. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：防止传真错误传输，并支持传真号码的平滑输入。解决方案：每当按下操作单元11的按钮时，与按钮相对应的数字被发送到对照单元21，并且对照单元21将输入的数字序列与允许的发送信号进行核对名单。在不能检测到与输入的号码序列前向匹配的传真号码的情况下，向用户警告不存在与输入的号码序列相对应的传送使能的传真号码。因此，用户可以在输入所有目的地FAX号码之前注意到错误。此外，在与输入的号码序列前进匹配的传真号码数量少的情况下，向FAX机1通知所有正向匹配的传真号码，FAX机1使用户选择任何传真号码。因此，用户可以容易地指定FAX的目的地。版权所有（C）2011，JPO＆INPIT
