    摘要： It is disclosed a method of demapping a tributary from a first frame into a second frame, the first frame comprising a plurality of tributary words and a synchronization word, the method comprising: providing a first and a second counters; increasing the first counter by a first value at each clock cycle of the second frame; and performing reading operations according to the second counter. It further comprises: generating synchronization information according to the synchronization word; according to the synchronization information, performing a change of state between a first state and a second state, wherein, in the first state, the second counter is synchronized to the first counter at each clock cycle of the second frame, and in the second state, the second counter is synchronized to the first counter at a predetermined instant of the second frame and the second counter is increased by a second value at each clock cycle of the second frame wherein the reading operation is performed.

    摘要： It is disclosed a digital crossbar comprising TDM switches with slicers at their inputs and deslicers at their outputs. The crossbar comprises mappers receiving respective client signals and mapping them into TDM input flows, which are fed to the slicers. The slicers slice each TDM input flow in different TDM input sub-flows on a per-tributary basis. The TDM switches switch the content of the TDM input sub-flows into a number of TDM output sub-flows, which are recombined by the deslicers thereby recovering TDM output flows carrying the original content of the TDM input flows. The crossbar also comprises demappers extracting the client signals from the TDM output flows. While the interconnectivity function is implemented by TDM switches, mappers and demappers allow the crossbar operating with any signal format in a transparent way. Implementing the interconnectivity function by TDM switches is advantageous in terms of scalability of the crossbar capacity.

    摘要翻译： 公开了一种数字交叉开关，其包括具有在其输入端的切片器和其输出端的去除器的TDM开关。 交叉开关包括映射器，其接收相应的客户端信号并将它们映射到TDM输入流中，馈送到分片器。 切片器在每个支路的基础上对不同TDM输入子流中的每个TDM输入流进行切片。 TDM交换机将TDM输入子流的内容切换成多个TDM输出子流，这些子流由去耦合器重组，从而恢复携带TDM输入流的原始内容的TDM输出流。 交叉开关还包括从TDM输出流中提取客户端信号的解映射器。 虽然互连功能由TDM交换机实现，但映射器和解映射器允许以任何信号格式以透明的方式操作交叉开关。 通过TDM交换机实现互连功能在交叉开关容量的可扩展性方面是有利的。
