摘要： Blocks of input data that include control words and a packet of information words are received (203; 252). The packet has a start preceded by ones of the control words and an end followed by others of the control words. The blocks are smaller than the packet. A determination of whether the block consists exclusively of information words is made (204; 253). When the block consists exclusively of information words, a master transition having a first sense is appended (207; 270) to the block to form a frame. When the block does not consist exclusively of information words, the block is condensed (e.g., 227; e.g., 260) to accommodate a TYPE word, the TYPE word is generated (e.g., 224; 266) and inserted (228; 271) into the block and a master transition is appended (213; 273) to the block to form the frame. The TYPE word has a value that indicates one of the following structural properties of the block: (a) the position of the start of the packet in the block, (b) the position of the end of the packet in the block, and (c) the block being composed exclusively of control words. The master transition appended to the block when the block does not consist exclusively of information words has a second sense, opposite to the first sense.
摘要翻译： 接收包括控制字和信息包分组的输入数据块（203; 252）。 该分组具有一个控制字前面的开头，另一个控制字后面跟着一个。 这些块比数据包小。 确定块是否仅由信息字组成（204; 253）。 当该块仅由信息字组成时，具有第一感测的主转换（207; 270）被附加到该块以形成一帧。 当块不仅仅由信息字组成时，块被压缩（例如，227;例如260）以容纳TYPE字，则产生TYPE字（例如，224; 266）并插入（228; 271）到 将块和主转换附加到块（213; 273）以形成该帧。 TYPE字具有指示块的以下结构特性之一的值：（a）块中的分组开始的位置，（b）块中的分组的结尾的位置和（ c）该块仅由控制字构成。 当块不完全由信息字组成时，附加到块的主转换具有与第一感觉相反的第二感觉。
