The switch unit includes a buffer memory for temporarily storing cells inputted from the input ports while forming a queue chain for each output line to which each cell is to be outputted, a demultiplexer for distributing the cells read from the buffer memory among the output ports in circulation, and a buffer memory control circuit for controlling the write and read operation of cells with the shared buffer memory. The buffer memory control circuit has a control table device for outputting an identifier of an output line to which the cells read from the shared buffer memory are to be outputted, and cells are read from the chain designated by the output line identifier outputted from the control table device.

摘要： The optical transmission apparatus for multiple wavelengths according to the present invention comprises; a light source, a temperature control section for controlling the temperature of the light source, a temperature control (ATC) loop for controlling the operation of the temperature control section, and a wavelength control (AFC) loop. The ATC loop detects the temperature of the light source and feedback controls the operation of the temperature control section, so that the optical output wavelengths of the light source fall within a wavelength capture range corresponding to a target wavelength of the AFC loop. The AFC loop has a wavelength detection filter having a periodic transmission wavelength characteristic. After the operation of the ATC loop has stabilized, a wavelength capture operation is commenced, and the operation of the temperature control section is controlled so that the optical output wavelength of the light source is captured at a stable point corresponding to a target wavelength, among a plurality of stable points.

摘要： This invention relates to a time division switching system for exchanging audio signals, data and so on in a time division manner. This time division switchboard comprises a plurality of separate local exchange units capable of interfacing with various different circuits such as subscriber lines, trunk lines, service circuits and so on, one or a plurality of junctor high ways connected to a time switch of each of the local exchange units, and one or a plurality of tandem exchange units each having a time switch connected to the other ends of the junctor high ways and switching by the time switch. Each of the local exchange units selects a channel on an arbitrary junctor high way and transmits control information concerning other one of the local exchange units to which a calling is to be sent, to one of the tandem exchange units which has the selected junctor high way connected thereto. The tandem exchange unit to which the control information is sent selects a channel on a junctor high way connected to the local exchange unit to which the call is to be sent, in response to the control information sent thereto, thereby switching the calling to the desired local exchange unit. Thus, since the respective units can be loosely coupled to each other, the time division switching system of this invention has high reliability and good economy.
