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： Any size and location of concatenated packet data across Synchronous Optical Network (SONET) frames in a SONET signal is provided. In one embodiment, a method may include receiving portions of packets and placing the portions into buffers. Additionally, the method may determine packet boundaries among the portions of packets in the buffers to locate a number of packets. Additionally, the method may concatenate the packet data into a Time Division Multiplexing (TDM) SONET signal. The concatenation can be across any locations within the TDM SONET signal, and the size of the concatenation can be in increments of single SONET frames. In another embodiment, the number of packets may be concatenated within locations in the TDM SONET signal not occupied by the TDM data traffic. In one embodiment, the TDM SONET signal having the concatenated packet data may be transmitted.

摘要： A frame based data communications network is interfaced to a synchronous digital hierarchy network via a plurality of frame based data port cards incorporated into a plurality of synchronous multiplexers. Each port card comprises a conventional frame based data port, a frame switch, a rate adapter means and a mapping means for mapping data frames into a plurality of SDH virtual containers. Frame based data is incorporated directly into a synchronous virtual container without encapsulation in an intermediate protocol. A number of topologies of a frame based data channel network are possible, overlaid on the underlying synchronous transport network, including an open loop topology, a ring mode topology, and a backhaul topology.

摘要： A non-interruptive protection switching device which performs protection switching in a more efficient and robust way. The device has a working-channel signal storage unit to store data signals received through a working channel. Multiframe synchronization timings are detected by a working-channel multiframe synchronization controller, which provides a working-channel multiframe sync detection pulse signal when the main signals are in a normal condition and stops it when the channel is disrupted. A working-channel write controller controls every write access to the working-channel signal storage unit, generating a write pulse signal therefor. The working-channel write controller also produces working-channel write phase data by identifying a phase difference of the detected multiframe synchronization timing with respect to a reference phase signal. The generation of this write pulse signal is based on the multiframe sync detection pulse signal when the working-channel multiframe sync detection pulse signal is available, or on a free-running timebase when it is stopped. The stored data in the working- and protection-channel signal storage units are read out simultaneously, under the control of a read controller which produces read pulses from the write phase data.

摘要： A system for transporting traffic is provided. The system transports traffic from a first network access path over a transport network path having multiple channels and transports traffic from a second network access path over the same transport network path. The system transports the traffic using transport network path channels wherein the bandwidth of the first network access path is higher than the capacity of any of the transport network path channels and wherein the bandwidth of the second network access path is higher than the capacity of any of the transport network path channels. The system allocates a first quantity of the transport network path channels for transporting traffic from the first network access path. The system allocates a second quantity of the transport network path channels for transporting traffic from the second network access path. And, the sum of the first quantity plus the second quantity is less than or equal to the total number of channels in the transport network path.
