摘要： A broad-narrow band integrated board includes: testing bus, for connecting the traffic signal to the testing device; switching unit matrix, for switching on the testing bus and the subscriber line, to make the traffic signal to be tested access into the testing bus, and at the same time establish the no-tested traffic channel. A method for testing the broad-narrow band integrated board includes: setting the testing bus and the switching unit matrix at the broad-narrow band integrated board; on-demand the switching unit matrix selecting the connect testing bus and subscriber line, to make the traffic signal to be tested into the testing bus, and at the same time establish the no-tested traffic channel; and testing the signal to be tested through the testing bus. It can carry a general test on the broad-narrow band integrated board through adopting the technical scheme in this invention; simultaneously it would not affect other signals when testing a signal.

摘要： A communication device and a method for saving static power consumption of communication device are disclosed. The communication device mainly includes a control signal unit, transmitting a control signal for cutting off power supply of at least one service unit of plurality of service units to a power control circuit unit; a power control circuit unit, cutting off power supply of at least one service unit of the plurality of service units according to the control signal. The method mainly includes: cutting off, by a control signal unit of the communication device, power supply of at least one service unit in the communication device according to an acquired control signal through a power control circuit unit of the communication device. According to the scheme, power supply of at least one service unit of the communication device may be cut off according to application requirements, to save the static power of the device, and reduce the static power consumption of the wideband parts of Integrated Voice Data (IVD) line card.

摘要： The present invention provides a method, an apparatus, and a system for time synchronization of an xDigital Subscriber Line (xDSL). The method includes: transmitting, by a customer premises equipment (CPE), a first symbol to a central office (CO) equipment, and obtaining time Ts2 indicating the moment that the first symbol is transmitted; receiving, by the CPE, a second symbol transmitted by the CO, and obtaining time Ts1 indicating the moment that the second symbol is received; obtaining, by the CPE obtains time Tm2 indicating the moment that the first symbol is received by the CO and time Tm1 indicating the moment that the second symbol is transmitted by the CO; the CPE calculates an offset between a clock of the CPE and a clock of the CO according to Ts1, Ts2, Tm1, Tm2 and a delay of the CPE; and the CPE adjusts the clock of the CPE according to the offset to achieve synchronization. According to the present invention, by adjusting the time of the clock of the CPE and the time of the clock of the CO, the offset between the clock of the CPE and the clock of the CO can be obtained accurately to effectively achieve time synchronization between the CPE and the CO.
