摘要： A communications system includes N parallel communications channels connecting first and second devices. The N channels may include N−1 channels for carrying information symbols, and an Nth channel for facilitating deskewing and word framing. The first device may include an alignment symbol generator for generating alignment symbols on the Nth channel, and a word framing code generator for generating word framing codes on the Nth channel. The second device may include a deskewer for aligning received information symbols based upon the alignment symbols, and a word framer for determining word framing based upon the word framing codes. The word frame code generator in the first device or transmitter, and the word framer in the second device or receiver provide the desired feature of knowledge of where each word starts or begins. The start of each word may be determined in terms of a time and a corresponding one of the N−1 channels where the word starts. The word framing code generator may generate word framing codes comprising at least one predetermined word framing code. Alternately, the word framing code generator may generate word framing codes including at least one changeable word framing code based upon information symbols.

摘要： A fibre channel (FC) signal representing block encoded data is applied to a block decoder, which removes the block encoding from the data. The data is then applied to a simplified data link (SDL) protocol encoder, which maps the data into an SDL protocol packet for transmission over a SONET (Synchronous Optical Network)-based transport medium.
摘要翻译：表示块编码数据的光纤通道（FC）信号被施加到块解码器，其从数据中去除块编码。然后将数据应用于简化的数据链路（SDL）协议编码器，其将数据映射到SDL协议包中，以通过基于SONET（同步光网络）的传输介质进行传输。

摘要： Asynchronous/plesiochronous digital hierarchy (PDH) signals, such as DS1 and E1, are transported using virtual concatenation. The packetized data signals are frame encapsulated and subsequently inverse multiplexed into a plurality of PDH frames. An overhead packet is inserted in the transmitted frames to enable the receiver to determine the status of the frames and extract the differential delay experienced by various frames as they are routed through virtually concatenated channels. The extracted delays enables the receiver to realign the various frames of the PDH signal to reconstitute the originally transmitted signals that travel through different paths of the transport network linking the source and sink of the virtually concatenated channel.
摘要翻译：使用虚级联方式传输诸如DS1和E1的异步/同步数字体系（PDH）信号。分组化数据信号被帧封装，随后被反向多路复用到多个PDH帧中。在发送的帧中插入开销数据包，以使接收机能够确定帧的状态，并提取各种帧在通过虚拟级联信道路由时所经历的差分延迟。所提取的延迟使得接收机能够对PDH信号的各个帧进行重新对准，以便重构通过连接虚拟级联信道的源和接收器的传输网络的不同路径行进的原始传输的信号。
