Estimating the term…
A plurality of digital signals of one or more digital transmission bit rates are arranged to be combined by employing a unique common channel frame format. The channel frame format includes a plurality of data bit positions and a plurality of overhead bit positions. The number of data bit positions used is dependent on the particular incoming signal. Similarly, the number of frames generated during a specific common framing interval is dependent on the digital transmission bit rate of the particular signal. Specifically, the number of channel frames generated during the common channel frame interval is dependent on a number of equivalent so-called lowest transmission bit rate signals included in the particular signal being formatted. The overhead bits are distributed in the channel frame format.
A digital frame formatter for generating channel frames each having a plurality of data bit positions and a plurality of other bit positions to facilitate combining a plurality of digital signals of one or more digital transmission bit rates, comprising,
A digital channel frame deformatter for generating a reconstructed one of a plurality of digital signals of one or more digital transmission bit rates from channel frames in a combined signal, the channel frames each having a plurality of data bit positions and a plurality of other bit positions, the deformatter comprising,
A formatting method for generating channel frames each having a plurality of data bit positions and a plurality of other bit positions to facilitate combining a plurality of digital signals of one or more digital transmission bit rates, comprising the steps of,
A deformatting method for generating a reconstructed one of a plurality of digital signals of one or more digital transmission bit rates from channel frames in a combined signal, the channel frames each having a plurality of data bit positions and a plurality of other bit positions, comprising the steps of,
A transmission system including a transmitter and a remote receiver, the transmitter including a digital frame formatter for generating channel frames each having a plurality of data bit positions and a plurality of other bit positions to facilitate combining a plurality of digital signals of one or more digital transmission bit rates, the formatter comprising,
