Title: Communication system and method therefor
IPC: H04J3/06
Filed: 1992-12-11
Abstract: PURPOSE: To detect a true TSO synchronization signal by using two time slot O detectors of worker/standby. CONSTITUTION: Data is transferred by a time slot. If synchronization is lost, one of worker TSO detectors executes a coincidence with a 1st effective frame synchronization signal, and another TSO detector expands the search of a mimic frame synchronization signal. In this case, a mimic-detecting facility is at the first of a scanning window, and is forcedly recoincided with an effective frame synchronization signal available at next. Then, in the first of a checking window, the start pulse of a worker and a standby frame are compared, and if neither exists simultaneously, a mimic alarm is generated and notified. Thus new scanning cycle is restrained, and the standby remains kept to be coincided with a new TSO. Relevant error data is analyzed, and one detector of two that coincides with a true TSO is determined.
