A communication apparatus which can carry out a facsimile communication with a calling station and a speech communication with the calling station. The communication apparatus includes, a monitoring block for monitoring received signals, a first determining block for determining, based on a result obtained by the monitoring block, whether or not a first signal transmitted from the calling station is received, a transmission block for transmitting a second signal to the calling station, a first c...

In a communication processing apparatus, communication processing system and communication processing method for performing communication processing between a transmitting unit and a receiving unit via a line, the transmitting unit converts audio into digital data, converts the resulting digital data into code data, units the resulting code data and document data prepared in advance and transmits the united data. The receiving unit receives the data from the transmitting unit, converts, into dig...

The present invention discloses a communication system in a network system having a plurality of user terminals connected to a communication network and a plurality of network resources accessed by the user terminals, the communication system having a communication part which makes the user terminals accessing the same network resource exchange and share communication information. The communication part has a communication server and a communication controlling part, provided in each user termin...

The communication method and communication apparatus according to the invention are capable of generating a packet having a header which includes at least data representing an identifier of a transmitting end point of a logical communication channel, data representing an identifier of a receiving end point of the logical communication channel, data representing an address corresponding to the identifier of the transmitting end point of the logical communication channel, data representing an addr...

First, communication data are transmitted from an arbitrary originating source communication device to the other plural destination communication devices. When receiving the communication data, the respective destination communication devices which receive the communication data make responses including the receiving states of the communication data to the originating source communication device, and thereafter change a next destination of the communication data into a next address according to ...

A path request repeating installation transmits a number of request subchannels used occupationally by communication data to be transmitted to all multiple destination repeating installations existing in paths from an originating source to destination, whereas the multiple destination repeating installations, which received the number of request subchannels from the path request repeating installation, refer to the received number of request subchannels and path information stored in path inform...

A communication system including a server having a state holding unit for holding variable state information and a state informing unit for holding a destination address of the state information to transmit the state information held by the state holding unit to the destination address. Further, a client's connected via a network to the server having plotting control for plotting one or more icons on an application, anyone of the icons being duplicatable between a plurality of mutually different...

A spread communication system comprising a receiver, a diffusion convertor for converting a signal from the receiver, a control signal generator for generating a control signal representing an output level of the diffusion convertor, another diffusion convertor for converting data to be transmitted, a transmitter for transmitting data from the another diffusion convertor and a transmission controller for controlling a transmission level of the transmitter in accordance with the control signal fr...

A communication apparatus includes a unit for starting power supply in accordance with external conditions, a unit for supplying power to the apparatus in accordance with a signal from the starting unit, and a unit for stopping power supply by the power supply unit after a predetermined operation such as a communication operation is completed.

A bidirectional broadband and telephony network is controllable from an exchange or head end of the network. An optical fiber (16 ) carries the telephone services to customers' premises (30, 31) via passive optical splitters (17, 18). Telephony is provided on one wavelength, broadcast TV on a second wavelength, and bidirectional asynchronous time division information on another wavelength using ATD techniques. Time-slots are allocated for information packets so they can travel without interferen...
