Patent ID: 7301967

Claim:
A method for processing time division multiplexed signals comprising the steps of: translating input frequencies to an intermediate frequency range, if necessary; determining whether a Phase Shift Keyed (PSK) or a Frequency Shift Keyed (FSK) or On-Off Keyed (OOK) modulation-type signal is present; demodulating said signal using said determined modulation-type so as to produce a digital data bit stream; bit synchronizing said digital data bit stream with a rate clock; stripping and decoding digital protocol from said digital data bit stream; digitally reformatting said digital data bit stream; synchronizing frames of said digital data bit stream; assigning said synchronized frames of digital data to channels; extracting said channel-assigned frames of digital data into individual channel streams; formatting said individual channel streams into a-law format; remultiplexing said formatted channel streams; wherein said step of remultiplexing further comprises the steps of: adding a sync byte to each frame; and adding idle bit patterns to unused channels so as to complete the requisite thirty one channels for a E1 frame; analyzing said channel streams to determine their contents; reformatting and outputting said channel streams; demultiplexing said reformatted said channel streams; converting said demultiplexed channel streams to analog channels; and outputting said analog channels.
