DISASTER-EARTHQUAKE Scenerio 1 : Earthquake on large FTTX deployed area Assumptions Main Telecom buildings are not damaged AC Mains is off Aftershocks are expecting Collapsed or Destroyed; Buildings Telecom İnfrastructure (Ducts, Pipes, Cables, Equipments …) High amount of incoming voice and Data traffic towards Disaster area Goverment agencies Relief agencies Press agencies ………

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 Scenerio 2 : Earthquake on large FTTX deployed area Main Telecom buildings are not damaged AC Mains is off Aftershocks are expecting Some buildings collapsed destroyed others undamaged Telecom infrastructure (Ducts, Pipes, Cables, Equipments …) partially destroyed in some areas but still big portion un damaged High amount of incoming voice and Data traffic towards Disaster area Goverment agencies Relief agencies Press agencies ………

DISASTER-EARTHQUAKE RESULTS Telecom infrastructure destroyed and out of service in some areas Big 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-FLOODING

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