The received data is passed through a buffer to the remainder of the station. A decoder at the receiving station generates an indication of buffer fill level and a local time-stamp is also generated. The output timing for the buffer is controlled by a circuit which is responsive to both a difference value off, received and locally generated time-stamps and to the fill level indication. | |
