DISASTER-EARTHQUAKE
Scenerio 1 : Earthquake on large FTTX deployed area
Assumptions
Main Telecom buildings are not damagedAC Mains is off Aftershocks are expecting Collapsed or Destroyed;

DISASTER-EARTHQUAKE
RESULTS
Telecom infrastructure destroyed and out of service
There is no way to quickly recover infrastructure and provide service other than Mobile capabilities.

DISASTER-EARTHQUAKE
RESULTS
Telecom infrastructure destroyed and out of service in some areasBig Part of Network in good condition and works
But still there is risk to loose all services
Since Mains off, Fuel is running out, Battery back up times are exceeding
How we can maintain services ?

DISASTER-EARTHQUAKE
Fiber cables more sensible pressure than copper cables
Ring or mesh topoloji critical for FTTC cabinets
Power shortage is very criticalSpare FTTX equipment or boards and
batteriesFireMore network people to diagnose problems
and put equipments in service
