Embodiments of the present disclosure relate to a Zero traffic hit synchronization switch over technique in a telecommunication network. The switch over is carried out by switching input reference of the receiver from one or more master (1) to at least one slave (2), wherein said slave (2) becomes new master (2) and said one or more master (1) becomes new slave (1) after switching. Now, the new master (2) locks to the new slave (1) for predetermined time period. Once the predetermined is elapsed, the new master (2) is disconnected from the new slave (1), wherein said new master (2) selects its own network reference clock upon disconnection of the new slave (1). The new slave (1) is locked to the new master (2) to synchronize the switchover in redundant systems.
