What is the best solution to synchronize your network ?
These requirements could be met by:
Installing a synchronization network based on the redundant and reliable master-slave tree structure: - HPS : master Primary Reference clock (usually redundant),
- US4G : GILLAM-FEI Synchronisation Supply Unit (Rubidium and Quartz technologies),
- GNCD : GILLAM-FEI Synchronization Distribution Unit.
- Using appropriate equipment for measuring the critical issue of wander accumulation in transmission networks: GILLAM-FEI PJS-2000.
3.Carrying out monitoring, remote control and network management in order to ensure its real-time maintenance with the GILLAM-FEI Network Synchronization Manager LYNX RSNM. |
