摘要： A method for passing communications over an Optical Transport Network (OTN) from a first communication interface to a second communication interface. The first interface extracts characters from received data symbols, maps the characters into OTN communication frames and discards the synchronization symbols. The mapping is performed using a Bit-synchronous Mapping Procedure (BMP), while filling some locations in the OTN frames with stuffing characters, so that the rate of the characters matches a desired rate of the OTN communication frames. The characters are extracted from the communication frames in the second communication interface by synchronizing to the mapped input frames independently of the synchronization symbols. The input frames are reconstructed to produce reconstructed input frames including the data symbols and the synchronization symbols, by re-encoding the extracted characters. In some embodiments, data from Ethernet frames is passed along with the extracted characters in the OTN frames.

The reception module receives a frame. The first detector detects a head position of a first layer, the head position being included in the frame. The second detector detects a head position of a second layer, the head position being included in the frame. The shift module shifts the frame so that the head position of the first layer and the head position of the second layer are located at respective predetermined positions. The first extraction module extracts a header of the first layer from the frame after the frame is shifted. The second extraction module extracts a header of the second layer from the frame after the frame is shifted.

摘要： A method for adapting the rates of a certain number of asynchronous HDLC channels (15) to a single clock domain suited for interfacing with an HDLC processor (13) through a synchronous pseudo-TDM interface (14) in which the HDLC channels are multiplexed in time and vice versa in the opposite direction. In one direction the algorithm is based on the writing of the HDLC channels in a dedicated buffer (17) and in reading these buffers with a common synchronous clock just above the expected maximum HDLC rate. The under-run condition is avoided by inserting neutral information between the end byte and the start byte of the HDLC packets when this is suggested by the buffer fill monitoring function. A simple function to locate the first and last bytes of each HDLC packet read by the buffer is hence used in combination with the buffer fill monitoring function. The algorithm is also suited in the opposite direction in which different asynchronous physical lines receive their HDLC channels from a synchronous TDM-type interface on condition that this interface clock domain be just below the minimum expected HDLC output rate. In this case also the under-run conditions are avoided by insertion of neutral data after having used the same algorithm described above. Adaptation devices and a telecommunications card using them are also proposed.
