Abstract: A method and apparatus for identifying at least a portion of a framing pattern in a data stream comprising a plurality of sequential bits. In the method embodiment, the method includes the step of identifying a set of successive candidate bits wherein the identified candidate bits are spaced apart from one another. The successive candidate bits include a first candidate bit, a last candidate bit, and a predetermined number of intermediary bits between the first candidate bit and the last candidate bit. Each of the intermediary bits has a numeric relative position between the first candidate bit and the last candidate bit. The method further includes the step of identifying a group of look ahead bits corresponding to each of the intermediary bits. Each of the groups has a number of look ahead bits, and the particular number of such bit for a given group equals the magnitude of the numeric relative position for the intermediary bit corresponding to the group.
