FIELD: information technologies.
SUBSTANCE: it is proposed in subsequent linear transport network built on the basis of system of synchronous digital hierarchy transfer, to include subsequently at least two secondary clock-pulse generators (SCPG), separately for each direction of synchronisation signals transfer.
EFFECT: improved quality of communication services by increasing quality of network synchronisation in case of accident of synchronisation signal sources and in case of failure in communication line between network elements.
