Physical layer coding violations framing method

We had seen in previous article framing, that to send packets from sender to the receiver framing is required. But the question was how the receiver will identify the starting and ending of a frame. For receiver, starting and ending of a frame is necessary to recognize the next frames transmitted by the sender.

So in this case Physical layer coding violations framing method will support.

  1. In this method some reserved signals are used to indicate the start and end of frames.
  2. As they are reserved signals, it is easy to find the start and end of frames.
  3. Here we are using ‘‘coding violations’’ by  putting reserved signals in original data.
