换句话说，校验字节的监测和检测过的SONET帧的不同部分中的错误。
In other words, parity bytes monitor and detect errors over different parts of a SONET frame.
接受方和发送方必须具有相同的帧长相同的校验方式，和相同的终止位。
Receiver and transmitter devices must have the same word length, the same parity and the same number of stop bits.
通过使用帧方式、CRC校验和选择重发纠错功能保证了协议的可靠性，该协议在一定程度上还可得到扩充。
The reliability of the protocol can be ensured by use of the frame format, CRC check, and correct function of selecting and sending repeatedly. The protocol can be extended to a certain extent.
当一个帧到达时，校验和将被验证。
论文介绍了多功能总线控制器编码器的设计，编码器有六个模块组成，分别为位控制单元、FIFO单元、帧分界符单元、数据转换单元、CRC校验单元和曼彻斯特编码单元。
The paper describes the design of encoder which is divided into seven modules: bit control unit, FIFO unit, frame delimiter unit, data conversion unit, CRC unit, Manchester encoding unit.
不利因素也随之产生，由于直通模式不做CRC校验，网络上的畸形和错误帧将增加。
The disadvantage is that the cut-through operation does not check for CRC errors, which increases the amount of runt and error frames on the network.
