摘要： PURPOSE:To provide a switching system which can deal with both STM and ATM signals by means of a single switch. CONSTITUTION:The address of a data memory 6 which stores temporarily an input signal for switching differs between an STM signal and an ATM signal. At the same time, the addresses given to the STM signal are registered into the address control memories 8 and 9. Then these addresses are periodically given to the STM signal. Meanwhile the addresses given to the ATM signal are stored in an idle address FIFO memory 10 in regard of the unused addresses. When the ATM signal is stored in the memory 6, the unused addresses are read out of the memory 10 and used in circulation. Both STM and ATM signals can be treated by a single switch and therefore the cost can be reduced at an area where both signals coexist.

摘要： PURPOSE:To reduce the power consumption of the ATM switch. CONSTITUTION:The ATM switch interchanges cells between plural input highways (1-1-1-4) and output highways (3-1-3-4) and have plural input ports provided corresponding to the output highways, and are provided with plural input memories (6-1-6-4) that the respective input ports can write data independently; and the input ports are connected to the input highways (1-1-1-4) respectively and the output ports of the input memories (6-1-6-4) are connected to the output highways (3-1-3-4). Then plural input FIFO memories are used as the input memories to omit multiplied structure, thereby suppressing an increase in power consumption.

摘要： PURPOSE:To confirm whether or not a sender of a signal and the signal are correct by setting a node number to a section overhead (SOH) at a node inserting the SOH and allowing a node separating the SOH to check the node number. CONSTITUTION:Each of wavelengths lambda1, lambda2 is allocated to signal paths 6-1, 6-2 respectively, a node B being a wavelength cross connector checks the wavelength and shares an input signal whose wavelength is lambda1 to a node C and an input signal whose wavelength is lambda2 to a node D. In this case, the node B does not implement the processing of an electric level, that is, the processing of a section overhead (SOH) and then the SOH added in the node A reaches the nodes C, D. One byte of the SOH is used in the node A for the insertion of the number of the node A to which a different number is allocated and it is detected by the nodes B, C. Thus, whether or not the sender of the signal and the signal itself are set correctly are confirmed.

摘要： PURPOSE:To receive frames having the various kinds of frame constitution by previously setting the specified frame constitution in a device, executing frame transformation in an interface part and unifying the frame constitution of the frame in the device. CONSTITUTION:In a frame synchronizing part 1, frame synchronizing is established and the frame phase of the received frame is matched with a 8k frame phase provided for the device. Then, the termination of a VC-4POH is executed by a POH termination part 5. When reading out A TUG-21 stored in a buffer memory 6 by a read control part 8, an AU pointer addition part 9 adds an AU-32 pointer to the output of the buffer memory 6. Thus, the received frame having the second frame constitution is transformed to the frame having the first frame constitution. Then, even in a network mixing the two kinds of the frame constitution, a processing in the device is made easy by unifying frame format in the interface part.

摘要： PROBLEM TO BE SOLVED: To prevent an unnecessary load increase and a wasteful use of radio resources by suppressing port scanning and paging by an illegal access in a radio communication system.SOLUTION: In a mobile communication network, when shifting from an active state in which a radio link is connected to an idle state in which a radio link is released, a mobile terminal 101 notifies a mobile gateway 105, which accommodates a mobile terminal in the radio communication network, of port information in communication or port information in a standby state. On receiving a packet destined to the mobile terminal in the idle state, the mobile gateway 105 initiates paging processing if the port information included in the packet matches the notified port state in communication or in the standby state.

摘要： PROBLEM TO BE SOLVED: To be able to monitor signal quality or the like with respect to a standby system even when an active system is in operation. SOLUTION: Upon the receipt of a check request signal 300 from a management system 250, a controller 230 transmits a switching request 310 to an optical switch drive circuit 164 that throws an optical switch 160 to take a position from a 1st transmission line 120 to a 2nd transmission line 130. A received signal performance monitor 190 gives a detection result 330 from the 2nd transmission line 130 to the controller 230 that throws the optical switch 160 to take a position from the 2nd transmission line 130 to the 1st transmission line 120. The controller 230 stores the detection result to a memory 240 according to a detection result storage instruction 360 on the basis of information from a 1st transmission line optical detector 210 and a 2nd transmission line optical detector 220. The management system 250 stores a result report 400 from the controller 230 to a storage device.

摘要： PROBLEM TO BE SOLVED: To miniaturize the scale of a multiplex device. SOLUTION: A low speed ATM(asynchronous transfer mode) interface part 100, an SDT (structured data transfer mode) line emulation interface part 200 and an UDT (unstructured data transfer mode) line emulation interface part 300 executes a part of a processing for terminating service which a stored low speed transmission line supplies and an AAL(ATM adaptive layer) processing being a preprocessing depending on service for generating an ATM cell from a signal received in terminated service. A processed signal is sent to a high speed interface part 500 by using a time slot which is previously allocated on a time division bus 600. The high speed interface part 500 once stores the signal received from the time division bus 600 in a buffer and executes the processing of a common part with respective signals generating the ATM cells stored in a pay load on the signal and transmits the generated ATM cell to the high speed transmission line by multiplexing them.
