ABSTRACT:
A communication circuit for providing a bi-directional data transmission over a signal line, thereby receiving a first digital data stream and transmitting a corresponding first signal into a near end of a signal line to a remote device, the remote device being connected to a far end of the signal line, receiving a second signal at the near end of the signal line from the remote device and deriving a second digital data stream therefrom, having a replica generator for providing, in response to the first digital data stream or a signal derived therefrom, a replica signal, and an extraction circuit for extracting the second digital data stream from the second signal in response to the replica signal and a comparator signal deduced from the near end of the signal line and an automatic test equipment having a plurality of communication circuits each providing a bi-directional data transmission.
