Abstract: The user operates a hand-held telephone to set the telephone in the suspend mode in which call termination at that telephone is denied, and to set the time duration of the suspend mode. After they are set, the time elapsed after the mode is started is automatically calculated. When the telephone receives a call before the set suspend duration time elapses, a message indicating the remaining time until the suspend duration time elapses and that the telephone is in the suspend mode is sent back to the calling party.

Abstract: Each network control section sequentially writes, into a common memory, data items included in a transmission frame output from each network, outputs a notification to notify start of writing and a notification to notify completion of normal writing, reads the transmission frame stored in the common memory in response to a transmission command, and transmits the read transmission frame to a corresponding network. When a C.T mode is set, a route control section receives the notification to notify start of writing from each network control section, and outputs a transmission command to a network control section corresponding to a destination network designated by a destination address included in the transmission frame. Further, when an S.

Abstract: In a bridge unit for connecting branch LANs through a trunk LAN, of address information registered in an address translation table, address information associated with a station not subjected to message transmission or reception for a predetermined period of time is recognized as address information to be deleted from the address translation table After this recognization, when a message is to be transmitted to a destination station represented by the station address included in the address information to be deleted, message transmission is performed by using the address information to be deleted When a response message is not received from the destination station, the address information to be deleted is deleted from the address translation table, and the message is retransmitted by broadcast.

Abstract: In an optical transmission system including a trunk LAN having duplex optical transmission lines, and branch LANs connected with the trunk LAN through nodes, an optical signal on the optical transmission line of the trunk LAN is input to a node including an optical switch, an optical transmitting and receiving circuit, a serial-parallel converter, an internal bus, and a LAN interface. The optical signal input to the node is converted to an electric signal (serial data) by the optical transmitting and receiving circuit through the optical switch, and is converted to parallel data by the serial-parallel converter. Thereafter, the parallel data is output onto the internal bus. The LAN interface performs an operation for outputting the parallel data onto the internal bus to the branch LANs. Data on the branch LAN is output to the optical transmission line by the operation opposite to that described above. The node can include a signal optical transmitting and receiving circuit.

Abstract: When the first message from a station is received by a LAN interface in a LAN connector unit, a source station address and a bridge port address are registered in an address translation table, and a flag T2 is set. This message is transmitted to the respective interfaces in the LAN connector unit by broadcast. Upon receiving this message, a flag T4 is set in the interface, and flags T1 are set in the other interfaces. When a WAN interface in another LAN connector unit receives the first message, a flag T2 is set. This message is transmitted from the WAN interface to the respective interfaces in the LAN connector unit by broadcast. The WAN interface is determined as an input/output interface associated with this message, and a flag T4 is set. A flag T1 is set in other interfaces. When the WAN interface receives a delayed message, since the flag T1 is already set therein, this interface is determined not to be an input/output interface for this message. A flag T3 is set in this interface.

Abstract: In a network system, a duplex transmission line has two transmission lines. Each transmission line, which is connected to a transmitting section, a receiving section and a serial/parallel converter, enables data transmission to be performed in a normal operating condition. When a fault is generated in the transmission lines, the fault position is separated by a line changing section and a folded loop is formed, whereby the network system is reconstructed.

Abstract: A table memory stores an address transformation table (AT table) which contains no address pairs therein before initialization of the system. A hash function memory stores a plurality of hash functions which are selectively used in correspondence with the sizes of a backbone network (BN) and a local area network (LAN), when an address pair consisting of a node address and a LAN address, of a LAN to which a node indicated by the node address belongs, is registered in the AT table. When a control unit receives frame data from the LAN or the BN, it automatically generates the above address pair consisting of the node address and the LAN address in the AT table by selecting one of the plurality of hash functions.

Abstract: An optical coupling unit connected to a single optical fiber includes first to fourth directional couplers each having three terminals. The optical coupling unit receives at a first side a first optical signal transmitted in a first direction through the fiber, and at a second side a second optical signal transmitted in a second direction through the fiber. The first optical signal is guided to the second side through first and second couplers and is guided through the first and third couplers to a first optical receiver. The second optical signal is guided to the first side through the second and first couplers and is guided to a second optical receiver through the second and fourth couplers. When an optical signal input to the second optical receiver is below a predetermined level, a first optical transmitter produces an optical signal formed by O-ring a second electrical signal from the second optical receiver and a transmission signal.

The preamplifier acts as a current amplifier for amplifying an output current signal from the photo-detector. The variable attenuating circuit acts as a current attenuating circuit for attenuating an output current signal from the preamplifier. The main amplifier amplifies an output current from the variable attenuating circuit and issues an amplified voltage.

Abstract: A timing extraction circuit includes a phase comparator, a charge pump circuit, a filter circuit and a voltage controlled oscillator, these components constituting a phase-locked loop. The phase comparator compares the phases of a digital data signal and a timing signal and supplies first and second difference signals to the charge pump circuit. The charge pump circuit detects a phase error corresponding to the difference between the integrals of the first and second difference signals. The filter circuit supplies a control signal corresponding to the phase error to the voltage controlled oscillator. The voltage controlled oscillator generates the timing signal having a period corresponding to the control signal.
