摘要： PROBLEM TO BE SOLVED: To notify a station device, over an access network, of maintenance and monitor information such as power supply interruption information of a user's set, via access networks of different managers between the station device and the user's set.
SOLUTION: A user's set 100 includes: a circuit 110 for monitoring a power supply voltage drop when power supply to the user's set itself is interrupted; and an internal power source capable of ensuring the time for transmitting power supply interruption information. A station device 101 is notified of the power supply interruption information by an Ethernet OAM frame in the ITU-T recommendation Y.1731. An MEG level between the station device and the user's set, which becomes an end point, is set to a value greater than an MEG level of an access network by a filtering operation at an MEG level of the OAM frame of the recommendation, thereby transmitting the OAM frame transmitted from the user's set through an access network 104 to be transferred to the station device. Power supply interruption cancellation is determined by receiving, at the station device, a term-monitoring response frame from the user's set with respect to a term-monitoring frame from the station device.

摘要： PROBLEM TO BE SOLVED: To perform an end-end continuity characteristic test without using a measurement instrument and without providing advanced test functions to a user access device. SOLUTION: The system has a test function in a relay device which constitutes a relay network wherein a plurality of user access devices are multiplexed. An end-end continuity characteristic test is performed using the relay device as a test starting point. The relay device sends a test frame to one user access device, and the user access device loops back the test frame to the same port. The relay device transmits the loopback test frame, and transfers the test frame to an opposed user access device. The opposed user access device returns the test frame to the same port. The relay device which is a test starting point terminates the test frame which is looped back again from the opposed user access device. Throughput and a delay time are calculated based on information contained in the test frame. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To assure high reliability required for a communication carrier network and at the same time provide an inexpensive high-functional packet relay device.
SOLUTION: The packet relay device includes multiple interface parts that send and receive data packets, two packet switches of active and standby systems to sort the received data packet to the interface parts corresponding to the addresses of the data packets, and a device control part that controls the multiple interface parts to send and receive control signals between operation devices connected to the outside. The interface parts receive control commands from the device control part. When the command instructs insertion of the diagnosis packet, the diagnosis packet is generated at a predetermined-fixed cycle and is inserted into the stream of data packets. If the diagnosis packet sent from other interface part via a packet switch does not come continuously over a predetermined number of monitoring cycles, the packet switch is controlled to switch the systems.

摘要： PROBLEM TO BE SOLVED: To provide a redundancy system that allows communication service to be continued even if multiple faults occur without a single fault point.SOLUTION: A redundant network system is made redundant about devices including a 0-system device and a 1-system device at a certain point in a network, and paths for system switching are set between a neighboring adjacent device 302 and the like and the 0-system device 305 and the 1-system device 308 respectively. A termination device 301 contacting with a user is set redundant paths with the 0-system device and the 1-system device. When the adjacent device has detected a fault of a port on physical port basis, it determines whether the fault port accommodates either of the 0-system path or 1-system path, and determines whether the 0-system/1-system path accommodated on the fault port is active or standby, and transmits a fault notification storing the determined fault status of 0-system/1-system and active/standby to the termination device 301. The termination device 301 includes means for determining whether it performs path switching or system switching from received multiple fault notification messages, and if the system switching is required, it transmits a system switching message to the adjacent device 302 and the like.
