Abstract
In a telecommunication system that employs asynchronous transfer mode (ATM) and minicells to transport communication data, accurate minicell header information dramatically improves the ability to align the minicells at a receiving station. More accurate minicell header information can be achieved by deriving a single header integrity check code (e.g., a cyclic redundancy code) for each ATM cell based upon minicell headers that have been inserted into contiguous locations in the ATM cell. By inserting the headers in contiguous locations, the receiving station can extract each header without having to rely upon the length indicator codes in each header, which may contain one or more bit errors. This, in turn, allows the receiving station to recompute the header integrity check code with far fewer errors, thus substantially increasing the probability of detecting and correcting the aforementioned errors and, ultimately, the ability to align the minicells.
