摘要:
A plurality of user terminals regularly accessing Internet Relay Chat (IRC) services are also in communication with a service selecting host. The service selecting host is configured to collect data from the plurality of user terminals. The collected data includes information about the users at the user terminals and information about the user terminals activity in the accessing of the IRC services. The service selecting host compiles and sorts the collected data concerning IRC services to produce information provided to the user terminals. The information provided to the user terminals allows users at the user terminals to more easily select sorted IRC services.

An ISDN interface unit interconnects a data processing unit, an ISDN, and an analog telephone and includes a DMA request signal generation circuit for generating a DMA request signal from an 8 kHz clock signal from an ISDN line. In accordance with the request signal, PCM coded data input from the ISDN line is transferred, using DMA, to a memory of the data processing unit or vice versa. Alternatively, the ISDN interface unit includes a code conversion circuit. Data stored in the data processing unit are converted to nonlinear PCM coded data and transmitted to the ISDN line or vice versa. Further, the ISDN interface unit includes communication functions for the digital signal and for the voice band signal, a control channel signal sent from the ISDN line is interpreted, and one of the communication functions can be selected.

A key management device for communicating with relay devices is provided, and one of the relay devices, which is communicating with a communication device based on master key information, transmits the master key information to the key management device. If the communication with the communication device has been enabled, the other relay devices makes a request to the key management device for transmission of the master key information. Then, the key management device transmits the master key information, which has been received from the one of the relay devices, to the other relay device, and then the other relay device can communicates with the communication device using the received master key information.
摘要:
There is provided a linkage apparatus for linking a plurality of telephones with one another, including a communication part communicating with the plurality of telephones, a detection part detecting operating states of the plurality of telephones, a determination part determining, on the basis of the detected operating states, whether or not the operating state of a first telephone out of the plurality of telephones has changed to a first state from a third state, and when it is determined that the operating state of the first telephone has changed, determining whether or not the operating state of a second telephone precedently set to be linked with the first telephone is a second state, and a decision part deciding a linkage process that the linkage apparatus makes the second telephone to execute when it is determined that the operating state of the second telephone is the second state.
摘要:
An intercept system includes: a call controller that controls a call between a plurality of communication devices connected through a packet network; a route setting device that sets a route along which communication on a call between the communication devices is relayed; a duplicating device that duplicates a packet to be intercepted; an acquiring unit that acquires communication device identification information for identifying positions on the packet network of the communication devices from the call controller; a setting unit that sets the route setting device in such a way that a packet received from one communication device is transmitted to the duplicating device as to communication on a call between the communication devices identified by acquired communication device identification information; and a returning unit that returns a received packet to the route setting device after duplicating the received packet by the duplicating device for use in interception.
