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.
摘要翻译：本发明提供了一种用于x数字用户线（xDSL）的时间同步的方法，装置和系统。该方法包括：由客户驻地设备（CPE）向中心局（CO）设备发送第一符号，并获取指示发送第一符号的时刻的时间Ts2; 由所述CPE接收由所述CO发送的第二符号，并获得指示接收到所述第二符号的时刻的时间Ts1; 通过CPE获得表示由CO接收到第一符号的时刻的时间Tm2和表示CO发送第二符号的时刻的时间Tm1; CPE根据Ts1，Ts2，Tm1，Tm2和CPE的延迟来计算CPE的时钟与CO的时钟之间的偏移; 并且CPE根据偏移量调整CPE的时钟以实现同步。根据本发明，通过调整CPE的时钟时间和CO的时钟时间，可以精确地获得CPE的时钟与CO的时钟之间的偏移量，以有效地实现CPE的时钟之间的时间同步 CPE和CO。
