Abstract:
An information transferring apparatus within a communication system for transferring an information block stream having valid cells containing valid data and idle cells containing no valid data, the information transferring apparatus comprising:a plurality of serially connected circuit packages including an input circuit package and an output circuit package, the circuit packages being connected such that the information block stream is transferred serially through each of the circuit packages from the input circuit package to the output package,wherein the input circuit package comprises:an idle cell detector which detects idle cells in the information block stream; andan information inserter which inserts control information into the detected idle cells; andwherein the output circuit package comprises a restorer to restore the detected idle cells having control information inserted therein to the idle cells as originally contained in the information block stream such that the information block stream exiting from the output circuit package is substantively identical to the information block stream prior to being transferred into the input circuit package.
