摘要:
In an ATU-R having established a connection with an ATU-C and being in a state where data communication is enabled, the ATU-R being located at a user's home, a voltage detection circuit detects a connector voltage of a connector to which a network cable of a user side is connected. When the connector voltage is decreased below a predetermined value in a state where power is supplied to an ADSL circuit of the ATU-R, the power supply to the ADSL circuit is stopped while maintaining a function related to detecting the connector voltage and controlling the power supply. The connector voltage is monitored even after the power supply is stopped. When the detected connector voltage becomes greater than the predetermined value, the power supply to the ADSL circuit is resumed.
摘要:
After establishing a connection between an ATU-C and an ATU-R and having a state where data communication is enabled, the ATU-R checks a packet that flows through a network at the user side. When there is no packet addressed to the ATU-R for a predetermined time period, the ATU-R transmits, to the ATU-C, a request to transition to an energy-save mode. The ATU-C and AUT-R determines a parameter to be used for the energy save mode, the parameter enabling a number of carriers and/or transmission power to be decreased compared to the ones in a normal mode. Using the determined parameter, a state in which data communication is enabled is maintained.

An IP telephone system includes an IP telephone apparatus, a Web server and an ENUM server. The IP telephone apparatus is connected to an IP network. The Web server registers talk volume information corresponding to a telephone number assigned to the IP telephone apparatus. The ENUM server registers a NAPTR resource record in which a URI specifies link data related to the talk volume information registered in the Web server. In the IP telephone system, the IP telephone apparatus that has received a call transmits, to the ENUM server, a query for a NAPTR record corresponding to a targeted recipient phone number. The IP telephone apparatus then transmits, to the Web server, a request for the talk volume information corresponding to the targeted recipient phone number according to the returned NAPTR resource record, and adjusts the talk volume according to the returned talk volume information.

An IP telephone system includes a source IP telephone apparatus, a destination telephone apparatus, a Web server and an ENUM server. The IP telephone apparatuses function as base stations for multi-handset telephone systems and are connected to an IP network. The Web server stores ring tone information corresponding to a telephone number assigned to the source or destination IP telephone apparatus. The ENUM server stores a NAPTR resource record in which a URI specifies link data related to the ring tone information stored in the Web server. In the IP telephone system, the IP telephone apparatus that has received a call transmits, to the ENUM server, a query for a NAPTR record corresponding to an intended recipient's telephone number. The IP telephone apparatus then transmits, to the Web server, a request for the ring tone information corresponding to the intended recipient's telephone number according to the obtained NAPTR resource record, and sounds a ring tone through the apparatus itself and the handsets that are connected to the apparatus according to the obtained ring tone information.
