#3: Operation & PerformanceMEVA Network performance and maintenance: Jun 2013-May 2014» Opened 191 trouble tickets this period» Summary» FAA to Santo Domingo problems revealed several systemic issues withinMEVA II network. Progress made but troubleshooting continues. See followon slides.» Majority of the trouble tickets were related to equipment issues:»»»»MemotecLynkway modemCustomer issuesHub equipment» Working with the sites to provide more complete information when callingthe SES GS NOC» Recommend referring to the Quick Reference Guide procedures» Also, recommend verifying all active circuits to determine if issue is relatedto all circuits (voice, data) or isolated to individual circuit before calling NOCSlide 3SES-GS Proprietary

Resolution of recurrent problemsFAA - Santo Domingo circuitsSummary of Issue: FAA to Santo Domingo voice and data circuits have beenunreliable with issues dating back to Sept 2013. Urgent actions required toresolve.Summary of SES GS actions to date: Formed Tiger Team to conduct deep dive analysis of problem Assessed issues at various sites and developed plans to resolve Conducted hand over hand check of equipment at Santo Domingo & replacedfaulty equipment at Santo Domingo, Miami and Atlanta Conducted assessment of IS-14 BW & identified low level interference Peaked & Poled Atlanta, Miami and Santo Domingo terminals Conducted extensive monitoring of Santo Domingo circuitsSlide 15SES-GS Proprietary
Resolution of recurrent problemsFAA - Santo Domingo circuitsOverall Trouble-shooting Plan 3-Step plan to resolve potential transponder saturation(1) Assess site transmit powers and potentially balance network(2) Provision new carrier on IS-14(3) Change all carriers from ¾ FEC to ½ FEC Establish baseline to extend for remainder of contract Work with Intelsat to resolve low level interference on IS-14 Review maintenance actions for other potential issues, ex.

Significant EventsSignificant Events June 2013 – May 2014» Santo Domingo – Atlanta AMHS and voice circuits becameunstable and an extensive troubleshooting and testing wasconducted. All MEVA equipment was replaced, bad wires werereplaced, antenna peak & poled. AMHS & voice circuits areunder test. Santo Domingo antenna need replacement» Planning to send the FAA contingency flyaway antenna to SantoDomingo. This action will affect the contingency plan» Miami MRT modem was found to be unstable, timing issue.Replaced the modem, timing is now stable» Miami antenna was peak & pol» Performed a power balance of the master reference signal to allsitesSlide 33SES-GS Proprietary
REDDIGSignificant Events June 2013 – May 2014, continue» Relocated the ANCC/AMRT from Woodbine to Atlanta, it isoperational and can be use as the back up for Miami» Conducted a synchronization & auto switching test betweenNCC & ANCC. Auto switching is not 100%. ANCC will not startthe AMRT automatically, need operator intervention. Procedureis in place to complete this function manually. Continued lookingfor a solution» Peak & pol Atlanta antenna. Discovered a small crack on thefeed Millar cover. The new feed has been received» SES-GS is working closely with IntelSat to eliminate a possibleASI affecting the entire networkSlide 34SES-GS Proprietary
REDDIGSignificant Events June 2013 – May 2014, continue» SES-GS is monitoring the total network bandwidth availabilityand is working closely with IntelSat to find a solution. Possiblesolutions;» Conduct a power balance for those sites that are transmittingwith high power. This action will lower the noise floorproviding additional margin» Add an additional 1.25 msps carrier to the network» Reduce the FEC on all carriers to 1/2, this action requirepush of new configuration files to all sites, high riskSlide 35SES-GS Proprietary
