摘要： According to one embodiment, there is provided an information terminal device which receives power via a communication cable from a power sourcing device recognizes a class identifying power-sourcing characteristics on the basis of response characteristics to a defined value voltage given in authentication and which is configured to connect an option unit. The information terminal device comprises a resistor unit which is disposed on a power sourcing line from the communication cable and configured to vary a resistor value, a control unit which recognizes a class of the information terminal device itself and sets a resistor value in order to achieve response characteristics corresponding to the recognized class, and a storing unit which stores the set resistor value.

摘要： According to one embodiment, a communication apparatus includes a processor, a detector, and a controller. The processor operates by a power class selectively set from a plurality of power classes including different maximum power supply amounts in accordance with a connected power sourcing equipment, and executes a communication process. The detector detects a count of an authentication process executed between the communication apparatus and the power sourcing equipment when the communication apparatus is connected to the power sourcing equipment. The controller sets in the processor a power class corresponding to the connected power sourcing equipment, based on a detection result obtained by the detector.

摘要： According to one embodiment, a headset interface circuit includes a connector, a plurality of amplifiers, a detector and an amplification switch. The connector selectively connects a plurality of headsets to a communication apparatus configured to operate at a predetermined power supply voltage and designed to provide telephone calls via a handset. The plurality of amplifiers selectively amplify an output signal from a transmitter of the headset and supply the communications apparatus with the amplified output signal. The detector cause a comparator to detect an operation current of the transmitter of the headset, wherein the comparator operating at a voltage of equal to or smaller than the power supply voltage. The amplification switch switches the amplifier based on a detection result by the detector.
摘要翻译：根据一个实施例，耳机接口电路包括连接器，多个放大器，检测器和放大开关。连接器选择性地将多个耳机连接到被配置为以预定电源电压工作并被设计为经由手机提供电话呼叫的通信装置。多个放大器选择性地放大来自头戴式耳机的发射器的输出信号，并向通信装置提供放大的输出信号。检测器使得比较器检测耳机的发射器的操作电流，其中比较器工作在等于或小于电源电压的电压。放大开关根据检测器的检测结果来切换放大器。
