摘要： A method for switching data signals transmitted over a transport network is disclosed. The method comprises receiving a plurality of input data signals of a first signal type wherein the plurality of data signals of the first signal type comprises data signals exchanged between a Radio Equipment and a Radio Equipment Controller and aggregating the plurality of input data signals into an aggregated first data signal. The method also comprises receiving a second data signal of a second signal type different to the first signal type, and multiplexing the first data signal with the second data signal to form a combined data signal. The method further comprises forwarding the combined data signal to the transport network. Multiplexing the first data signal with the second data signal comprises, for a frame of the combined data signal, allocating the first data signal to a portion of the frame reserved for the first data signal, and allocating the second data signal to a remaining portion of the frame.

摘要： Optical Transport Network (OTN) High Order (HO) mapping systems and methods utilize pointer processing to map one HO signal into another similarly sized HO signal. An OTN HO mapping method and circuit include receiving a first HO signal at a first rate, asynchronously mapping the first HO signal into a second HO signal at a second rate, wherein the first rate and the second rate are substantially similar, translating a portion of overhead from the first HO signal to overhead of the second HO signal, utilizing pointers in the overhead of the second HO signal for frame alignment of the first HO signal, and transmitting the second HO signal containing the first HO signal.

摘要： A failure protection method of a network connecting between nodes by multiple working paths and a protection path is disclosed. An allocation bandwidth is determined to allocate to a detected path where a failure is detected in multiple paths being set to the multiple working paths, depending on the detected path. The detected path is switched from one of the multiple working paths to the protection path. Data to be transmitted by the detected path is transmitted by using the allocation bandwidth determined within an entire bandwidth of the protection path.

摘要： A digital transmission system includes at least a client device and a transmission device, and rate-adjusts the client signal transmitted from the client device to the transmission device before accommodating/multiplexing the signal in a frame. The transmission device includes a rate adjusting unit and a frame processing unit. The rate adjusting unit encapsulates the client signal by using a predetermined frame structure, inserts an idle pattern if necessary, and performs rate adjustment into the bit rate which can be contained in the frame. The frame processing unit accommodates/multiplexes the signal after the rate adjustment. The digital transmission system inserts a bit string of the client signal directly in a payload area of the digital frame, or accommodates and multiplexes it. Alternatively, a specific pattern is accommodated in the payload area, or accommodated and multiplexed after performing a reversible digital signal processing.

摘要： Signal format conversion apparatus and methods involve converting data signals between a first signal format associated with a first reference clock rate and a second signal format that is different from the first signal format and is associated with a second reference clock rate different from the first reference clock rate. A period of the second signal format is changed to match a period of a third signal format by controlling a synchronized second reference clock rate that is applied in converting data signals between the first signal format and the second signal format. The synchronized second reference clock rate is different from the second reference clock rate and is synchronized with a third reference clock rate. The third reference clock rate is associated with the third signal format. Such synchronization simplifies conversion of signals between the second and third signal formats.
