摘要： The invention relates to a multiplexing method used in a PDH network. Standard PCM signals are received in the network element, at least some of which are multiplexed on a time-division basis into the same outbound transmission frame, the capacity of the payload portion of the frame substantially corresponding to the capacity required by N PCM signals. In order that ATM cells may be transferred more advantageously than heretofore through an existing PDH network, the multiplexing is implemented as configurable in such a way that the total capacity of the payload portion cab be divided between at least two parts of variable capacity in such a way that each part can be allocated a desired portion of the total capacity of the payload portion in accordance with the current transmission requirement. A part of the payload depending on the desired capacity is allocated to at least one traffic source from a group in which a number of PCM signals constitutes a first traffic source and a number of packet data streams constitutes a second traffic source. The invention is specifically intended for transferring ATM traffic through a PDH network.

摘要： Switch frames are arbitrarily concatenated to allow for any available time slots to be used for carrying concatenated switch frames. Methods and apparatus transport switch frames in available time slots, and keep track of which time slots correspond to a group of concatenated switch frames. The switch frames are transported through the switch and synchronized on the outgoing side of the switch so that arbitrarily concatenated switch frames are synchronized with each other.

摘要： Data frames are converted to a format suitable for transparent, flexible concatenated transport such that a network element not supporting flexible concatenation may transparently pass the data frames. Flexible concatenation involves nonstandard data frames such as an STS-4c or an STS-Nc in which the time slots do not occupy rigidly defined contiguous time slots. In transparent flexible concatenation, the pointer from the parent time slot is used for each of the child time slots and the concatenation identifier is set to indicate no concatenation. In this way, the concatenated data appears to be a series of conventional STS-1s such that pointer processing may be successfully accomplished even by a network element not capable of handling non-standard concatenations. A downstream receive framer reconstructs the original STS-Nc based on the N STS-1s and a concatenation table the contents of which are shared between the transmit framer and the downstream receive framer.
摘要翻译：数据帧被转换成适合于透明，灵活的级联传输的格式，使得不支持灵活级联的网络元件可以透明地传递数据帧。灵活连接涉及非标准数据帧，例如STS-4c或STS-Nc，其中时隙不占用刚性定义的连续时隙。在透明灵活连接中，父时隙中的指针用于每个子时隙，并且级联标识符被设置为指示不连接。以这种方式，连接的数据似乎是一系列常规STS-1，使得甚至可以通过不能处理非标准级联的网络元件来成功地实现指针处理。下行接收成帧器基于N STS-1重建原始STS-Nc，并且在发送成帧器和下行接收成帧器之间共享其内容的级联表。

摘要： A method and apparatus are provided for flexible time-division multiplexing, and demultiplexing, of serial line data, from 1-n client lines, based on the SONET standard (e.g. OC-48 or OC-192) whereby a predetermined and reconfigurable number of STS-1s are allocated to each client. A multiplexer includes 1 to n mappers for mapping the data of 1 to n clients, according to a predetermined bandwidth allocation, to an NnullSTS-1 SON ET payload, each mapper using y STS-1s where y is 0 to N, the y STS-1s being selected on a sequential or non-sequential concatenation basis from the N STS-1s. Each mapper maps the data of one client and each allocated STS-1 is allocated to one client and the total number of STS-1s allocated to the clients is less than or equal to N. An aggregator aggregates the mapped data into a composite STS payload comprising N STS-1s. A bandwidth allocation receiver receives the bandwidth allocation. The bandwidth allocation may be received from a source external to the multiplexer and the source may be a network controller. A demultiplexer includes a deaggregator for deaggregating the STS payload to provide the mapped data for the clients. 1 to n demappers demap the client data according to the predetermined bandwidth allocation. A bandwidth allocation receiver receives the bandwidth allocation.
