  • at least two transmission channels; and

    a receiving module connected to the transmission channels and having a loop-back conductor which operably connects the two transmission channels and returns a packet containing error bits if one or more of the transmission channels downstream of the receiving module is disturbed, wherein the error bits comprise an error value set by the receiving module if the receiving module fails to receive a null pattern for a length of time exceeding that which is used to send a packet.
