1. A method for achieving zero traffic hit synchronization switchover in a telecommunication network including a plurality of line blades, said method comprising acts of:
switching, by a network element, input reference of a receiver from one or more master controller (1), configured to lock to a network reference clock to provide clock signals to the network, to at least one slave controller (2), wherein said at least one slave controller (2) becomes a new master controller (2) and said one or more master controller (1) becomes a new slave controller (1) after switching; locking, by the network element, the new master controller (2) to the new slave controller (1) for a predetermined time period while line blades synchronize to the new master controller; disconnecting, by the network element, the new master controller (2) from the new slave controller (1); selecting, by said new master controller (2), its own network reference clock upon disconnection from the new slave controller (1); and locking, by the network element, the new slave controller (1) to the new master controller (2) for synchronizing the switchover in redundant systems, and achieving zero traffic hit synchronization switchover. |
