Traffic in various routes between the nodes is continually measured in the communication stations and the measuring results are stored in a database storage unit. Future traffic in the various routes is predicted on the basis of the information on the continually measured traffic by the use of a predetermined algorithm and stored in the storage unit for use in determination of routes for communication messages on the basis of the result of the communication performance prerequisites discrimination and predetermined criteria with respect to the updated information on the predicted traffic in the storage unit.

    摘要: An optical receiving method utilizing polarization diversity is disclosed in which first and second reference lightwaves having different frequencies and having polarization planes substantially perpendicular to each other, are combined with a signal lightwave to form a combined lightwave. The combined lightwave is subjected to heterodyne detection to obtain a detection signal and the detection signal is separated into first and second intermediate-frequency signals having different carrier frequencies. The first and second intermediate-frequency signals are converted into first and second baseband signals, respectively, and the first and second baseband signals are added to obtain an output signal.

    摘要: A high speed digital signal multiplexing method and apparatus are provided wherein a plurality of first higher bit rate transmission frames are provided, each first higher bit rate transmission frame being multiplexed therein with lower bit rate signals in an n-byte (n is an integer) interleave manner, and the lower bit rate signals are selectively derived from the plurality of first higher bit rate transmission frames and multiplexed into a second higher bit rate transmission frame. When a phase conflict is detected among the derived lower bit rate signals, all the data columns of at least one of the derived lower bit rate signals are given a predetermined delay by means of a shift register, and the derived signals are multiplexed into the second higher bit rate transmission frame. When a first higher bit rate transmission frame asynchronous with the system frame is detected, a pointer is derived which pointer represents a predetermined information unit within the derived lower bit rate signal. The derived pointer is inserted into a time slot corresponding to the frame pattern position of the second higher bit rate transmission frame for the lower bit rate signal. Thereafter, the derived signals are multiplexed.

    摘要: For reducing the scale of a multiplexer, a lower speed ATM interface block, an interface block for SDT mode circuit emulation, and an interface block for UDT mode circuit emulation perform processing for terminating services provided by lower speed transmission lines accommodated therein, and part of AAL processing, which is pre-processing depending on a service, for generating ATM cells from signals received by a terminated service, and send the processed signal to a higher speed line interface using a previously assigned time slot on a time-division bus. The higher speed line interface once stores the signals received from the time-division bus in a buffer, and subsequently performs certain processing including a common portion for respective signals for generating therefrom ATM cells in which the signals are stored in payloads. The generated ATM cells are multiplexed and transmitted onto a higher speed transmission line.
