Synchronization Map
Synchronization of network elements and how the clock information is propagated through the network, determine the integrity of information transmission through the network.
To ensure that this operates correctly, FOXMAN-UN provides the SDH and PDH Synchronization Map functionality.
This facility helps the operator to trace the clocking information through the managed network, and identify:
• which network element in the network is supplying the clock;
• any 'clock islands', where a network element clock is generated locally and is not propagated to any other network element;
• Any 'timing loops' which may have inadvertently been created by propagating the clock from a network element back to a network element which is providing the clock source.
With the synchronization map the operator can graphically display the actual clock propagation of either the SDH or PDH part in the managed network.
A synchronization map can be generated for all or for a user defined selection of the managed network elements.
Synchronization Map
The current timing source information is collected from all the FOX61x and FOX51x network elements through the polling mechanism. Therefore the synchronization map reflects the timing situation at the moment of the poll of each network element. The map can be updated manually.
