Synchronous data repeater having noncompatible signal bypass

Claim 1

IN A SYNCHRONOUS DATA SIGNALLING SYSTEM WHEREIN SYNCHRONIZING SIGNALS SEPARATED BY FIXED TIME INTERVALE ARE RECOVERABLE FROM THE DATA SIGNALS, A TRANSMITTER FOR SENDING SAID SYNCHRONOUS DATA SIGNALS, A DATA SIGNAL RECEIVER, AT LEAST ONE REPEATER BETWEEN SAID TRANSMITTERAND RECEIVER FOR REGENERATING SAID SIGNALS, SAID REPEATER INHERENTLY PROVIDING A DELAY OF SAID REGENERATED SIGNALS, INTERMITTENTLY OPERATED MEANS HAVING A NEGLIGIBLE INHERENT DELAY FOR PASSING SAID SIGNALS FROM THE INPUT OF SAID REPEATER TO THE OUTPUT THEREOF TO BY-PASS SAID REPEATER, AND DELAY MEANS EXTERNAL TO AND CONNECTED IN SERIES WITH SAID REPEATER BETWEEN SAID INPUT AND SAID OUTPUT FOR DELAYING SAID REGENERATED SIGNALS TO PROVIDE AN ACCUMULATIVE DELAY INTERVAL WITH THE INHERENT DELAY OF SAID REPEATER WHICH EXCEEDS THE DELAY OF SAID INTERMITTENTLY OPERATED MEANS BY AN INTERVAL EQUAL TO AN INTEGRAL MULTIPLE OF SAIDF FIXED TIME INTERVALS.
