摘要： PROBLEM TO BE SOLVED: To prevent increase in a load of network processing due to mis- discrimination of an ATM connection state caused by the effect of production of a physical layer fault and due to a notice processing undesired attended with a transmission line fault restored immediately in the fault monitor of the ATM connection with respect to an OAM(operation and maintenance) function in the ATM(asynchronous transmission mode) exchange technology. SOLUTION: This processor 100 monitors an arrival state of an alarm cell as to each ATM connection and discriminates an ATM connection receiving an alarm cell at a time interval within a prescribed time to be an alarm state and an ATM connection not receiving an alarm cell over a prescribed time to be a normal state based on the result of monitor. When a fault of a physical layer with respect to the ATM connection discriminated to be in an alarm state is detected, the ATM connection is discriminated to be in an alarm state regardless of the result of a monitor till the fault is recovered.

摘要： PURPOSE:To obtain a traffic observation device in which a call processing software reads correctly an observed traffic quantity. CONSTITUTION:The device is provided with a 1st measurement means 1 measuring a traffic with the hardware, a storage means 2 for a measures result, a flag display means receiving the control of a call processing software 240, and a 2nd measurement means 4 operated by the control of the flag display means and the timing transmission means. In the case of transmission of a timing signal, the storage means stores the result of the 1st measurement means to a memory address corresponding to the display value of the 2nd measurement means to clear the 1st measurement means. When the call processing software 240 reads the storage content, the software 240 sets the flag display means to read the content corresponding to the relevant memory address. When the flag display means is set in the transmission of the timing signal, the 2nd measurement means is reset and counts up the 2nd measurement means in the reset state.

摘要： PROBLEM TO BE SOLVED: To improve the effect of congestion control by specifying and extracting connection to be the cause of congestion and controlling cell flow-in to an ATM exchange when the congestion is detected. SOLUTION: When the overflow of a cell buffer 1421 and cell abandonment are continued for more than fixed time set beforehand, it is judged that this ATM exchange 11 is in a congestion state in a congestion judgement part 15. The header information inverse conversion part of an input line coping congestion control part 1 obtains the call origin information of an abandoned cell by reading and inversely converting the header information of the cell abandoned in the cell buffer 1421 . In an input line specifying part, the connection to be the cause of the congestion is extracted corresponding to the call origin information and an input line 2111 is specified. A congestion control part 16 sets input control to the input control part 1311 of a line coping part 131 for housing the input line 2111 and controls the flow-in of the cell to the ATM exchange 11.

摘要： PROBLEM TO BE SOLVED: To autonomously perform the band regulation of a virtual channel(VC) in a hardware without burdening call processing software by imparting a flag to the part of plural virtual channels and providing a means for regulating the VC to which this flag is imparted. SOLUTION: After a starting instruction is given to a timer, an enable signal is outputted for every set fixed period by call processing software 210 and a flag control part 1 outputs the reset instruction of the flag indicating an input regulation to a connection control part 2. A flag set/reset control circuit 111 receiving the enable signal outputs a reset signal. The connection control part 2 rewrites the flag of a connection holding memory 120 from a flag control part 1, based on the flag set instruction and the reset instruction for this address. An input regulation part 4 executes an input regulation processing, based on the contents of the connection holding memory 120.

摘要： PROBLEM TO BE SOLVED: To autonomously perform the band regulation of a virtual channel(VC) in a hardware without burdening call processing software by dividing plural virtual channels into two groups or more and providing a means cyclically imparting a regulation for every group. SOLUTION: A counter 122 for table retrieval receiving a signal decides a VC group executing an input regulation for the counter value that the counter holds. The VPI/VCI information of the cell passing a cell drop circuit 120 and the VPI/VCI information read from a band regulation control table #N are compared in an input regulation decision circuit 123 and a scrapping processing is performed for only the cell having pertinent VPI/VCI information in the cell drop circuit 120. Namely, header information is copied by a cell extractor in the cell drop circuit 120 inputted in an input regulation part 12, the information is held, a comparator compares the VPI/VCI information and the VPI/VCI of a control table and only the cell having the VPI/VCI is dropped.

摘要： PURPOSE:To highly precisely count the number of passing cells at every counting time zone without any error by a little hardware amounts without depending on the number of the counting time bands. CONSTITUTION:A cell number counting circuit 20 is equipped with A and B double surfaces count value tables 11 and 12, and a counting surface resistor (counting surface identifier) 13 which displays the counting surface in the time zone, so that the number of the passing cells at every time band is enabled to separately count. When the cell reaches, the count value of the counting surface shown by the counting surface identifier is increased by 1. The counting surface can be simultaneously switched for entire logical channels by rewriting the value of the identifier, and the number of the passing cells at every logical channel number can be counted separately at every logical channel without any error.
