Abstract: Embodiments of the present invention provide a method for activating a DSL. The method includes: sending, by a central office equipment, a sync frame period indication message to a customer premises equipment, where a sync frame period indicated by the sync frame period indication message is smaller than a specified sync frame period threshold; receiving a reply message sent by the customer premises equipment in response to the sync frame period indication message, where the reply message indicates whether the customer premises equipment accepts the sync frame period indicated by the sync frame period indication message; and if the reply message indicates that the customer premises equipment accepts the sync frame period, performing, by the central office equipment, vectoring training by using a corresponding sync frame within the sync frame period. The embodiments of the present invention further provide corresponding equipments, a system, and a program product.

Abstract translation: 本发明的实施例提供了一种激活DSL的方法。 该方法包括：由中心局设备向客户驻地设备发送同步帧周期指示消息，其中由同步帧周期指示消息指示的同步帧周期小于指定的同步帧周期阈值; 响应于所述同步帧周期指示消息，接收由所述客户驻地设备发送的应答消息，其中所述应答消息指示所述客户驻地设备是否接受由所述同步帧周期指示消息指示的同步帧周期; 并且如果所述回复消息指示所述客户驻地设备接受所述同步帧周期，则由所述中心局设备通过在所述同步帧周期内使用对应的同步帧执行向量化训练。 本发明的实施例还提供对应的设备，系统和程序产品。
