Abstract

A method and apparatus for analyzing a bit stream having an unknown format that is conveyed through a communications network. The method includes the steps of: (a) storing a plurality of sequentially occurring bits received from a communications network; (b) analyzing a plurality of the stored bits to detect periodicities in the bits; and (c) determining if the detected periodicities exhibit characteristics associated with a known type of data communications format, particularly a synchronous time-division-multiplexed (TDM) data communications format or a packetized data communications format. The step of analyzing includes a step of performing a statistical analysis of the stored bits.
