Abstract
Synchronization of a receiving termination of a telecommunications system with an incoming data stream is carried out from a synchronization signal carried with the data stream. It is possible that a 'mimic' of the synchronization signal may occur within the data stream. Two frame alignment detectors operate in worker/standby relationship, one being locked to a detected synchronization signal and the second searching for an alternative signal. Verification is carried out using a cyclic redundancy check.
