METHOD FOR LOCK SYNCHRONISATION OF GENERATORS OF RAILWAY DIGITAL COMMUNICATION NETWORK Russian patent published in 2010 - IPC H03L7/08 

FIELD: radio engineering.

SUBSTANCE: in the method, a generated reference synchronisation signal is transmitted over a main transportation digital network. The synchronisation signal is transmitted to second level transmission system generators through corresponding generators of network elements of the road level transport network to which a reference synchronisation signal is transmitted through network elements and driving generators of the main transportation digital network. Synchronisation signals are transmitted to technical cooperation department switching centres from network elements of the first level transmission system which receive the synchronisation signal from network elements of the second level transmission system, and a standby synchronisation signal in emergency mode for the last local section of the synchronisation circuit, which does not have other sources of the standby signal, is generated using a standby driving generator in standby mode and is connected to the synchronisation circuit of the last local section only in case of emergency of the main synchronisation signal.

EFFECT: reduced phase jitter of the synchronisation signal and highly reliable operation of the synchronisation network on dead-end directions.
