The present invention provides a communications method of a modem, including: determining a current power supply mode; if it is determined that the current power supply mode is that a network device is used to supply power by using a copper twisted pair, switching a communications interface from a fiber interface to an electrical interface, where the electrical interface connects to the network device by using the copper twisted pair and the fiber interface connects to a passive optical network by using an optical fiber. The present invention further provides a modem, and a wireless charging method and device. According to the technical solutions provided in the present invention, it is implemented that a service can still be provided after an external power supply is powered off.

An adapter includes a passive branch circuit configured to communicate a first cable television (CATV) signal between an input port and a passive port, an active branch circuit configured to receive a second CATV signal from the input port, and a sensor configured to detect a low-power condition in the active branch circuit. The active branch circuit is configured to terminate the second CATV signal in response to the sensor detecting the low-power condition, and the active branch circuit is configured to communicate the second CATV signal from to one or more active ports when the active branch circuit does not terminate the second CATV signal.

A personal mobile device receives a session-request message requesting establishment an encrypted-audio session with a call-initiating device. In response, one or more call-response inquiries are presented via a user interface of the mobile device. The one or more call-response inquiries include an accessory-status inquiry with respect to an accessory to the mobile device. The mobile device receives, via the user interface, an accessory-unready indication with respect to the accessory, which is associated with the presented accessory-status inquiry. In response to receiving the accessory-unready indication, the mobile device establishes a communication link with the call-initiating device and refrains from exchanging audio data with the call-initiating device via the established communication link. The mobile device makes an accessory-ready determination and responsively establishes the encrypted-audio session at least in part by receiving encrypted-audio data from the accessory and forwarding, via the established communication link, the encrypted-audio data to the call-initiating device.

A network that is to execute transcoding is fixed. IMS networks set an information element that requests either of the IMS networks to execute transcoding into the SDP, and use that information element to select the IMS network that is to execute transcoding between the IMS networks. Then, the selected IMS network executes transcoding of media data.

The facsimile apparatus of the present invention, and the method of controlling the same, switches a connection between a telephone device and a telephone line between connected and cut off, has a power supply for supplying power to the telephone device, and, in a state where the telephone device and the telephone line are connected and supply of power from the power supply to the telephone device is stopped, in a case that an off-hook of the telephone device is detected by a detection unit for detecting an off-hook and an on-hook of the telephone device, controls to start supply of power from the power supply to the telephone device.

A method and security system arrangement are disclosed for processing incoming signals at an alarm monitoring station. The method includes analyzing the incoming signals to assess if any particular incoming signal includes characteristics of a facsimile signal to thereby identify whether or not a given incoming signal is a facsimile signal. If the analyzing identifies that a given incoming signal includes characteristics of a facsimile signal, thus identifying that the given incoming signal is likely a facsimile signal, the alarm monitoring station refrains from initiating an alarm handling procedure to handle the given incoming signal. Caller ID information may be extracted from the facsimile signals received by the alarm monitoring station, and added to a call block list. Calls originating from caller IDs on the call block list may be blocked by the alarm monitoring station.

A phone comprising: a phone body, at least one sensor on the phone body for measuring a vital sign of a user when the phone is held in use; means for converting the vital sign measurement into a voice-frequency band signal; and means for transmitting the voice-frequency band signal for use in monitoring the health of the user.

An information processing apparatus (10) includes a processor capable of executing IP facsimile communication and a job other than the IP facsimile communication, a facsimile tone signal being transmitted/received as audio data in the IP facsimile communication; a storage (12) that stores a first or second level, which represents a mode for executing the IP facsimile communication; and a control unit (11) that determines whether the first or second level is stored in the storage, respectively selects a first mode and a second mode when determining that the first level and the second level are stored in the storage, and when receiving an execution instruction of the IP facsimile communication in the first mode and the second mode, respectively causes the processor to stop an uncompleted job and then preferentially execute the IP facsimile communication, and to execute an uncompleted job and the IP facsimile communication in parallel.

Non-voice data is embedded in a voice bit stream that includes frames of voice bits by selecting a frame of voice bits to carry the non-voice data, placing non-voice identifier bits in a first portion of the voice bits in the selected frame, and placing the non-voice data in a second portion of the voice bits in the selected frame. The non-voice identifier bits are employed to reduce a perceived effect of the non-voice data on audible speech produced from the voice bit stream.

A network that is to execute transcoding is fixed. IMS networks set an information element that requests either of the IMS networks to execute transcoding into the SDP, and use that information element to select the IMS network that is to execute transcoding between the IMS networks. Then, the selected IMS network executes transcoding of media data.
