Abstract: A data link control method including receiving a message (30) for transmission over a cable communications system. The method determines a number of octets in the message (30). When the number of octets is less than or equal to a predetermined number of octets, the method sets a frame length (44) equal to the number of octets and transmits a frame (180) containing the message (30). When the number of octets is greater than the predetermined number, the messages (30) is segmented (32-42), each segment being identified in order with respect to the other segments. The method thereby provides for graceful communications resumption when the transmission of a message is interrupted before completion.
Abstract translation: 一种数据链路控制方法,包括接收用于通过有线通信系统传输的消息(30)。 该方法确定消息(30)中的八位字节数。 当八位字节的数量小于或等于预定数量的八位字节时,该方法设置等于八位字节数的帧长度(44),并发送包含消息(30)的帧(180)。 当八位字节数大于预定数量时,消息(30)被分割(32-42),每个段相对于其他段按顺序被标识。 因此,在完成之前中断消息传输时,该方法提供了适当的通信恢复。
