2. Goals of Project
Implementation of kingdom wide network to serve all ANS facilities
Support ATM and ATC data and voice flows
Form a single and robust communication infrastructure
Provide redundancy for links and communication hardware
Provide simplicity and scalability of addition of applications
Monitoring communication facilities to identify faults

3. Present ANS Communication
Individual links for each application
Lack of redundancy at Hardware and link levels
Addition of application requires new circuits and hardware
Delay of lunching of applications due to unavailability of lines

11. NAN Monitoring
NAN Monitoring tools provide graphical representation of the NAN and allow monitoring NAN devices and links
Monitoring include: hardware faults, link status, bandwidth utilization and topology changes
NNMC: Located in Jeddah and Riyadh ACC’s and will supervise the whole NAN.
RNMT: Located in other sectors and Jeddah HQ and will monitor sites related to the sector.
