摘要:
In a data transmission device and method provided with e.g. duplexed switches outputting frames in the order of input for continuing the communication without instantaneous interruptions even though one of the switches are faulted, input interfaces generate frames in which every time data is inputted, input order information indicating the input order is added to the data together with unique information of each input interface and providing the frame generated to the switches in parallel. At least one output interface sequentially stores the frames outputted from the switches for every unique information and selects a first arrived frame among the frames stored with same input order information.

A ceramic electronic component includes a ceramic base, first and second internal electrodes, and first and second external electrodes. The first external electrode is disposed at a first end portion of a first major surface in the longitudinal direction. The second external electrode is disposed at a second end portion of the first major surface in the longitudinal direction. A portion of each of the first and second external electrodes is opposed in the thickness direction to a region where the first and second internal electrodes are opposed to each other in the thickness direction. A condition ( 1/10)t0≦t1≦(⅖)t0 is satisfied, where t0 is the thickness of each of the first and second external electrodes and t1 is the thickness of a portion in which each of the first and second external electrodes is embedded in the first major surface.

Disclosed is a method of setting a bidirectional path between a first node and a second node in a network. A first path from the first node to the second node is established by a first path establishing procedure in which a first path message including a record of a route through which the first path message is forwarded from the first node to the second node. A second path from the second node to the first node along the route of the first path in the backward direction is established by a second path establishing procedure in which a second path message including a route specification determined based on the record of the route included in the first path message is transferred from the second node to the first node.
摘要:
A method for time-division multiplexing including steps of generating a plurality of first signals and a plurality of second signals to which specific pulse trains for frame synchronization are allocated respectively; generating low speed signals of plural channels including the first and second signals and transmission signals; a conversion step; and time-division multiplexing the low speed signals after the conversion step, thereby obtaining high speed signals. When applied to SDH, for example, the first and second signals may be A1 bytes and A2 bytes respectively, and the transmission signals may ho payload signals. According to one aspect of the invention, at the conversion step, the first and second signals in each channel are panty convened into either of “1/0” alternating signals and “0/1” alternating signals. Consequently, it becomes possible to reduce the number of successive same code and to diminish the deviation of the mark rate.
摘要:
An optical-signal transmission apparatus and method for optical-signal transmission, or a signal processing apparatus for signal processing including optical-signal transmission. A number of terminals (circuit boards and the like) are connected, and communication can be freely performed among the terminals. A plurality of transmission nodes input optical signals having different light intensity levels into an optical transmission medium. A desired signal is separated and extracted from a multiplex signal where these optical signals transmitted from a reception node are overlaid.

An apparatus for storing digital data includes a clock pulse source and plural serial shift register stages storing data bits. Digital data signals, each having plural databits, are coupled to and shifted in the stages in synchronization with the clock pulses. Data stored in the memory stages stages are held in a non-erasable memory unit provided for each stage while an emergency causing a failure of a power supply of the shift register occurs.
