    • ‘A method and apparatus for performing adaptive differential pulse code modulation.’
    • ‘The line module test can be done remotely using two different loop backs, one prior to the A / D conversion (PCM (pulse code modulation) loopback) and one after the conversion (analog loopback).’
    • ‘A first channel has an output electrically connected to the input line of the line interface circuit, and the first channel has inputs for both a pulse code modulation input and a xDSL input.’
