摘要： An optical transmission technique for a ring transmission system that can transmit time-division-multiplexed optical signals in dual directions. An optical transmitting apparatus comprises a data link reading section, a topology creating section, a data link writing section, a squelch table creating section, a squelch table, an RIP table creating section, an RIP table, a node recognizing section, an east-side receiving unit, an east-side transmitting unit, a west-side transmitting unit, and a west-side receiving unit. When a transmission route is switched at plural positions, the squelch table and the RIP table are automatically created as soon as a crossconnect is set. With minimum setting, the ring transmission system can be normally operated without increasing the number of setting items, the squelch table can be created at a high speed using existing hardware, and an alarm can be automatically transmitted from a secondary node until each table is created.

摘要： A transmission device in which a bus of a central processing unit is used to synchronize timing signals between units, thereby restraining enlargement in scale of wiring. A reference signal generator generates a reference signal. A reference signal receiver is mounted on a unit set as an active or standby unit and receives the reference signal. A timing signal generator divides the frequency of the received reference signal by means of a frequency divider/counter to generate a timing signal. A count holder holds the count value of the frequency divider/counter. The bus connects the units and the central processing unit. A count receiver receives, via the bus, the count value from the count holder of the active unit. A count updater updates the count value of the frequency divider/counter to the count value received by the count receiver.

摘要： In a power supply monitoring device, a power supply voltage monitoring portion always monitors a power supply voltage supplied to a monitored circuit and outputs a voltage reduction signal when detecting that the power supply voltage is reduced below a predetermined threshold (e.g. a second voltage higher than a voltage guaranteeing a normal operation of the monitored circuit and lower than a rated voltage). A monitoring controller having received the voltage reduction signal determines whether or not an operational malfunction has occurred in the monitored circuit by comparing operation data of the monitored circuit with reference data of the monitoring controller itself. Also, the monitoring controller executes recovery processing (reset processing or reference data overwrite processing) suitable for the monitored circuit referring to a prestored recovery processing type specific to the monitored circuit when detecting an operational malfunction of the monitored circuit.

摘要： A transmission device comprises a plurality of types of exchangeable duplexed interface cards on a receiving side and a transmitting side; an STS or VC switch card having functions of setting a signal route between the interface cards by an STS or VC on the receiving side and the transmitting side and of switching over a duplexed system in at least one of an interface card unit, a line unit, an STS path unit and a VC path unit; and a monitoring portion controlling the STS switch card and the transmitting side interface cards upon switching, and setting a signal route. For upgrading the transmission device, when an interface card is upgraded in service by increasing a transmission capacity of the duplexed already-existing interface cards, an interface card on a standby side is exchanged with an interface card having a larger capacity, the monitoring portion performs the same setting as that of an interface card on an active side, switches over the interface card on the standby side to the active side as well as the interface card on the active side to the standby side, by controlling the STS or VC switch card and a switch portion of the transmitting side interface card, and exchanges the interface card with an interface card having the capacity.
