MOPS, CON/TRA and IBS are built and interconnected to provide 5 levels of contingency and backup as follows:

 Level-I to Level-III redundancy is provided within the MOPS and IBS.

 Level-II to Level-III redundancy is provided within the CON/TRA (Contingency mode).

 Level-I : All servers and internal network in the system is duplicated and operate simultaneously.

 Level-II : Fall-back Surveillance Data Processing (FSDP) servers run in parallel with Duplicated Main Surveillance Data Processing (MSDP) servers and seamlessly take over the operations on failure of MSDP.

 Level-III : Surveillance Direct Access (SDA) Processing servers provides continuation of surveillance tracking data to the operator in the event of a failure of the both MSDP and FSDP. 10 / ATMS Contingency & Backup

 Level-IV redundancy is provided through CON/TRA.

 The CON/TRA system runs in Contingency Mode (CON mode) and takes over the operations of MOPS in event of MOPS failure or unavailability.

 Level-V redundancy is provided through IBS.

 The NAS IBS takes over the operations of NAS MOPS in the event of disaster at NAS (BACC, BAPC).

 The APP IBS takes over the operations of any one of the APCs in event of disaster at APC. 11 / ATMS Contingency & Backup

Infrastructor Test (IFT)

• To demonstrate that the installed equipment meets iits requirements.

Syetem Site Function Test (FUT)

• To demonstrate that the system is “fit to the purpose” through operation and functional test scenarios. 17 / Acceptance Process

Integration Test (ITT)

• To demonstrate the proper interaction, exchanges of data and operation of the sub-system comprising the TMCs

System Continuous Test (SCT)

• To demonstrate the proper interaction, smooth exchanges of data and operation of thr entire TMCS for a continuous period of 90 days. 18 / TMCS Transition status on 7 Nov 2018 19 / TMCS Transition status on 7 Nov 2018 20 /
