摘要： PROBLEM TO BE SOLVED: To construct a remote monitoring and control channel without decreasing the number of user data channels in a system for remotely monitoring and controlling user's equipment from a station device over the Ethernet. SOLUTION: Both a maintenance management (OAM) channel and a user data channel are used together. Namely, user terminals 130, 131 connected to a user's equipment 110 are connected with a station device 100 in a point-to-point manner. Route management over the Ethernet is managed by means of a VLAN. As illustrated, the user terminal 130 is accommodated in the station device 100 by means of a VLAN 120 via the user's equipment 110, and the user terminal 131 is accommodated in the station device 100 by means of a VLAN 121 via the user's equipment 110. An Ethernet OAM frame can be transmitted/received using the user data channel. Thus, a remote monitoring and control channel can be constructed without decreasing the number of user data channels.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration of the reception relevant part or the failure in a reception side transmission device reliably without using an attenuator.SOLUTION: In the output value control method controlling the output value of the output information transmitted from each transmission device 1, a transmission device 1A transmits the output information in a state having the smallest output value to a transmission device 1B, and notifies the smallest output value as its own output value to the transmission device 1B. When the output information does not arrive at the transmission device 1B, the transmission device 1A increases its own output value by a predetermined value from the previous output value, and repeats transmission of the output information and notification of its own output value during transmission. Upon receiving the output information, the transmission device 1B calculates the output value of the transmission device 1A on the basis of the output value thus notified, and notifies the output value of the transmission device 1A thus calculated as an output proper value to the transmission device 1A. The transmission device 1A performs transmission and reception with the transmission device 1B on the basis of the output proper value thus notified.

摘要： PROBLEM TO BE SOLVED: To accommodate a non-interrupt-switching-desiring user and a low latency-desiring user coexisting with each other in a single device in a redundantly configured packet transfer network.SOLUTION: A device includes both a processing procedure for a non-interrupt-desired packet and a processing procedure for a low latency-desired packet, and processes the respective user packets using desired procedures. The phase of a non-interrupt-desired packet is aligned by delay parts 506 and 526 and is then stored in non-interrupt-use memory 508. Further, a low latency-desired packet is also stored on low latency memory 510 and 530 without going via the delay part 506 or 526 and therefore is not delayed. Read control parts 512 and 532 read packets from the non-interrupt memory 508 and 528 and output them as is if the read packets are non-interrupt-desired packets, or discard them if the read packets are low latency-desired packets and read low latency-desired packets from the low latency memory 510 and 530 and output them.

摘要： PROBLEM TO BE SOLVED: To quickly execute congestion control by generating promptly an RM cell added with congestion information in a communication equipment in which congestion occurs, and transmitting it to a communication terminal or the communication equipment transmitting a cell to be the factor of cell buffer congestion. SOLUTION: When the quantity of inter-device cells accumulated in cell buffers 2a, 2b exceeds a threshold, the congestion is judged to have occurred, and a cell buffer detecting part 3 detects the identifier of the cell buffer in which the congestion occurred, and reports it to line dealing with parts 100a, 100b. Cell buffer identifier-to- received cell header information retrieving parts 5a, 5b generate newly a congestion reporting RM cell having the same VPI and VCI as the VPI snf VCI of the detected identifier in the header. Selector parts 7a, 7b receive the control of the information retrieving parts 5a, 5b, and insert the congestion reporting RM cell into the transmission cell, and output it to interfaces 300a, 300b, and transmit it directly to a cell transmitting origin making the congestion. Thus, response time till the communication terminal or the communication equipment transmitting the congestion factor cell slows down transmission cell speed is shortened.

摘要： PURPOSE:To use a relay line for general talking and a fault transfer line in common without provision of an adaptor to each relay station by connecting the fault transfer line from an unattended station to a maintenance in charge station with connection processing by a telephone number and transferring fault information. CONSTITUTION:When a fault information transfer circuit 6 of a station 15 subjected to maintenance detects a fault, a transmission control circuit 5 starts a relay station 16 to connect a fault information receiver 13 of a maintenance in charge station 17 via a relay station 16 similarly to the case with a general channel. Then the fault information receiver 13 reaches a state similar to a reply of a general talking and the reply signal is sent to a transmission control circuit of the station subjected to maintenance similarly to the case with a general talking. Upon the receipt of a reply signal, the transmission control circuit 5 connects a channel to a fault information transfer circuit 5 to make communication between the fault information transfer circuit 6 and the fault information receiver 13. Thus, a relay line for general talking and the fault transfer circuit are used in common without provision of a special means for fault transfer to the relay station 16.

摘要： PURPOSE:To enable a display to match an actual road by a handy means by judging whether a peripheral road data of the current position read out of a map data coincides with a correction road data read in a semiconductor memory. CONSTITUTION:An arithmetic processing section 5 reads a peripheral road data of the current position out of a CD-ROM 6 to be sent to display device 7 following a data conversion. A moving speed and an ongoing bearing of a vehicle are supplied to the arithmetic processing section 5 from a vehicle sensor 1 and a bearing sensor 2. The arithmetic processing section 5 determines the current position of the vehicle from the data obtained and displays it superimposed with a road displayed on a display device 7. When the peripheral road data of the current position read out of the CD-ROM 6 differs from an actual road, for example, correction information of a road is written into a semiconductor memory 4 from a scan switch 3. The arithmetic processing section 5 judges whether an area of a data for correction read out from a memory 4 coincides with that of the peripheral road data of the current position to project correct road information to the display device 7 by a correction processing of a road data.
