10. Application: Bridging the Digital Divide
• In the following slides, you will find a project that is
successfuly implemented in Azerbaijan
• Rural telephony backbone of Azerbaijan is now fully
digitalized with this project
• This project is a pioneering example for those
countries that are upgrading, reconstructing or
rebuilding their telecommunication infrastructures

Increased effiency in call processing by replacing the functionality of the mechanical modules.
Huge electricity and maintenance savings from omitted analog modules:
Savings comparable with budget of the project itself
