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.

摘要： A method for generation of a clock (22) synchronized with time references derived from input signals (12) in an apparatus (10) of a telecommunications network comprising an input part (11) receiving the input signals and a part (13) for treatment of said input signals is described. In the input part (11) the method comprises the steps of deriving the time reference signals from the input signals, reading a edge of the reference signals, establishing the position of this edge relative to the internal data frame, inserting in the frame heading a pointer representing the established position of the edge relative to the frame and sending the frame to the treatment part. In the treatment part (13) the method comprises the steps of receiving the frame, extracting said pointer, generating said time reference clock (22) and synchronizing it with the position in the frame indicated by the pointer. An apparatus applying this method is also proposed.
