SDH Network Management System (SDH NMS)

The SDH network is being remotely managed by a Network Management System installed in Sofia. All operations are carried out from centralized locations, ensuring the network’s proper operation and monitoring. Functions provided by the SDH NMS comply with the International Management Networks (TMN) standards of the ITU-T. This system can be expanded to cover the management of other SDH multiplexers installed in the country.
